Abstract (sommario):

PurposeIn the internet economy, the business model of web portals has spread rapidly over the last few years. Despite this, there have been very few scholarly investigations into the services and characteristics that transform a web site into a portal as well as into the dimensions that determine the customer's evaluation of the portal's service quality.Design/methodology/approachBased on an empirical study in the field of e‐banking, the authors validate a measurement model for the construct of web portal quality based on the following dimensions: security and trust, basic services quality, cross‐buying services quality, added value, transaction support and responsiveness.FindingsThe identified dimensions can reasonably be classified into three service categories: core services, additional services, and problem‐solving services.Originality/valueThe knowledge of these dimensions as major determinants of consumer's quality perception in the internet provides banks a promising starting point for establishing an effective quality management for their e‐businesses.

AbstractWeb-based expert systems (WBESs) provide the benefits of both expert system technology and web technology. The use of web services to deliver functionalities of WBESs allows the integration of these systems in web-portals. WBESs are used in a diversity of areas like engineering, management, medicine, agriculture, education, tourism, finance etc. A study on the various features of WBESs like knowledge-representation, reasoning, languages, implementation tools, use of various web services-related processes such as discovery, selection, composition etc. can result into some interesting conclusions. Presented work tries to fulfill the same purpose. The paper presents various WBESs classified according to their use of domain. The comparisons, observations, and assessments of these systems are presented by emphasizing the above-mentioned features of WBESs. A discussion on different web services-related processes and some representative techniques for performing each has also been provided to clarify their use in the WBESs. On the basis of assessments and surveys from different perspectives, some remarkable conclusions are drawn.

Abstract (sommario):

This investigation aimed to determine the use of web 2.0 services in the Catholic University Cecilio Acosta (UNICA) site by the institution, located in Maracaibo city, Venezuela. The theoretical contributions were supported by O'Reilly (2007), Lévy (2004), Rheingold (2004), Surowiecki (2005), Cobo (2007a), among other authors. The investigation comes from a project attached to the UNICA Research and Postgraduate Deanery, was descriptive, an observation guide was applied to collect information from the UNICA website and the 2.0 services to which it is associated as the platforms for vertical social networks YouTube, Instagram and SoundCloud, and platforms for horizontal social networks Facebook and Twitter. Among the most relevant findings was the exclusive use of social networking services for interaction with the university community, without including other services that seek to generate knowledge. It is concluded that UNICA uses web 2.0 services in its site in a limited and non-strategic way, with a purely informative nature that includes specific topics of the university and the catholic church, which could hinder the knowledge management as process of 21st century universities.

Abstract (sommario):

This paper introduces and compares two innovative tools aimed at enhancing the collaborative work of the researchers and professionals from the West Balkan countries in the Semantic Web field. The first tool, the Alfresco system, is a version controlled content repository designed in REST architectural style and based on a set of document management and collaboration services. The Alfresco workflow engine enables organization and automation of the process activities. The second tool, the Semantic MediaWiki portal, is a semantic collaboration tool and knowledge management system that leverages the latest Semantic Web (SW) technologies and standards. By using semantic annotations, it enriches the Web contents with semantics and makes the knowledge explicit. Thus, it provides structured access to information and accurate and precise knowledge retrieval. This paper discusses the customization of these tools and their utilization in the Web Technologies for West Balkan countries (Web4WeB) project.

Abstract (sommario):

North Eastern Region (NER) of India comprising of eight states considered to be most unique and one of the most challenging regions to govern due to its unique physiographic condition, rich biodiversity, disaster prone and diverse socio-economic characteristics. Operational Remote Sensing services increased manifolds in the region with the establishment of North Eastern Space Applications Centre (NESAC) in the year 2000. Since inception, NESAC has been providing remote sensing services in generating inventory, planning and developmental activities, and management of natural resources, disasters and dissemination of information and services through geo-web services for NER. The operational remote sensing services provided by NESAC can be broadly divided into three categories viz. natural resource planning and developmental services, disaster risk reduction and early warning services and information dissemination through geo-portal services. As a apart of natural resources planning and developmental services NESAC supports the state forest departments in preparing the forest working plans by providing geospatial inputs covering entire NER, identifying the suitable culturable wastelands for cultivation of silkworm food plants, mapping of natural resources such as land use/land cover, wastelands, land degradation etc. on temporal basis. In the area of disaster risk reduction, NESAC has initiated operational services for early warning and post disaster assessment inputs for flood early warning system (FLEWS) using satellite remote sensing, numerical weather prediction, hydrological modeling etc.; forest fire alert system with actionable attribute information; Japanese Encephalitis Early Warning System (JEWS) based on mosquito vector abundance, pig population and historical disease intensity and agriculture drought monitoring for the region. The large volumes of geo-spatial databases generated as part of operational services are made available to the administrators and local government bodies for better management, preparing prospective planning, and sustainable use of available resources. The knowledge dissemination is being done through online web portals wherever the internet access is available and as well as offline space based information kiosks, where the internet access is not available or having limited bandwidth availability. This paper presents a systematic and comprehensive study on the remote sensing services operational in NER of India for natural resources management, disaster risk reduction and dissemination of information and services, in addition to outlining future areas and direction of space applications for the region.

Abstract (sommario):

The interoperability problems of distributed databases are important in the developing of the operatively working web services aimed for all sectors of public administration. The following web services are designed for solving tasks in water resource management and contamination evaluation sector with a due attention to the international environment protection context. The paper is devoted to problems of developing the component‐based architecture of the integrated decision‐support system that afford ground for the monitoring and intellectual analysis of water management. Such investigations are made according to the requirements of European Union (EU) Water Framework Directive, Sustainable development Directives and EIONET ReportNet infrastructure. The main components of decision‐support system are analyzed by using different knowledge modelling and web service development techniques. The structure of water resource management information system (WRMIS) becomes the core of the decision‐support system in which web services are implemented. The main components for evaluation of processes of contamination and water monitoring are represented by data warehouse structures. The solutions to satisfy the interoperability requirements are demonstrated by architectural design decisions of the system, integrating the distributed data warehouses and geographical information system means. The web services are based on common portal technology. The organizational and political arrangements require deeper and stronger participation activities by all member states of EU in reporting, understanding the importance of sustainable development problems and risk evaluation possibilities.

Abstract (sommario):

The paper illustrates the potentials of geospatial data to access a historical digital atlas for landscape analysis and territorial government. The experience of a historical geo-portal, the “Atl@nte dei Catasti Storici,” in the management of geo-referenced and non-geo-referenced maps—ancient cadastral and topographic maps of the Lombardy Region—can be considered a case study with common aspects to many European regions with an extensive cartographic heritage. The development of downstream Web-based services enables integration with other data sources (current maps, satellite and Unmanned Aerial Vehicle [UAV] airborne photogrammetry, and multi-spectral images and derived products). This provides new scenarios for retrieving geospatial knowledge in support of more sustainable management and governance of the territory.

Abstract (sommario):

SummaryBackground: An increasing amount of health education resources for patients and professionals are distributed via social media channels. For example, thousands of health education videos are disseminated via You-Tube. Often, tags are assigned by the disseminator. However, the lack of use of standardized terminologies in those tags and the presence of misleading videos make it particularly hard to retrieve relevant videos.Objectives: i) Identify the use of standardized medical thesauri (SNOMED CT) in You-Tube Health videos tags from preselected YouTube Channels and demonstrate an information technology (IT) architecture for treating the tags of these health (video) resources. ii) Investigate the relative percentage of the tags used that relate to SNOMED CT terms. As such resources may play a key role in educating professionals and patients, the use of standardized vocabularies may facilitate the sharing of such resources. iii) Demonstrate how such resources may be properly exploited within the new generation of semantically enriched content or learning management systems that allow for knowledge expansion through the use of linked medical data and numerous literature resources also described through the same vocabularies.Methods: We implemented a video portal integrating videos from 500 US Hospital channels. The portal integrated 4,307 YouTube videos regarding surgery as described by 64,367 tags. BioPortal REST services were used within our portal to match SNOMED CT terms with YouTube tags by both exact match and non-exact match. The whole architecture was complemented with a mechanism to enrich the retrieved video resources with other educational material residing in other repositories by following contemporary semantic web advances, in the form of Linked Open Data (LOD) principles.Results: The average percentage of YouTube tags that were expressed using SNOMED CT terms was about 22.5%, while one third of YouTube tags per video contained a SNOMED CT term in a loose search; this analogy became one tenth in the case of exact match. Retrieved videos were then linked further to other resources by using LOD compliant systems. Such results were exemplified in the case of systems and technologies used in the mEducator EC funded project.Conclusion: YouTube Health videos can be searched for and retrieved using SNOMED CT terms with a high possibility of identifying health videos that users want based on their search criteria. Despite the fact that tagging of this information with SNOMED CT terms may vary, its availability and linked data capacity opens the door to new studies for personalized retrieval of content and linking with other knowledge through linked medical data and semantic advances in (learning) content management systems.

Abstract (sommario):

Background Studies have shown the effectiveness and user acceptance of mobile health (mHealth) technologies in managing patients with chronic kidney disease (CKD). However, incorporating mHealth technology into the standard care of patients with CKD still faces many challenges. To our knowledge, there are no reviews on mHealth interventions and their assessments concerning the management of patients undergoing dialysis. Objective This study provided a scoping review on existing apps and interventions of mHealth technologies in adult patients undergoing chronic dialysis and identified the gaps in patient outcome assessment of mHealth technologies in the literature. Methods We systematically searched PubMed (MEDLINE), Scopus, and the Cumulative Index to Nursing and Allied Health Literature databases, as well as gray literature sources. Two keywords, “mHealth” and “dialysis,” were combined to address the main concepts of the objectives. Inclusion criteria were as follows: (1) mHealth interventions, which are on a smartphone, tablet, or web-based portals that are accessible through mobile devices; and (2) adult patients (age ≥18 years) on chronic dialysis. Only English papers published from January 2008 to October 2018 were included. Studies with mHealth apps for other chronic conditions, based on e-consultation or videoconferencing, non-English publications, and review papers were excluded. Results Of the 1054 papers identified, 22 met the inclusion and exclusion criteria. Most studies (n=20) were randomized controlled trials and cohort studies. These studies were carried out in 7 countries. The main purposes of these mHealth interventions were as follows: nutrition or dietary self-monitoring (n=7), remote biometric monitoring (n=7), web-based portal (n=4), self-monitoring of in-session dialysis-specific information (n=3), and self-monitoring of lifestyle or behavioral change (n=1). The outcomes of the 22 included studies were organized into five categories: (1) patient satisfaction and acceptance, (2) clinical effectiveness, (3) economic assessment, (4) health-related quality of life, and (5) impact on lifestyle or behavioral change. The mHealth interventions showed neutral to positive results in chronic dialysis patient management, reporting no to significant improvement of dialysis-specific measurements and some components of the overall quality of life assessment. Evaluation of these mHealth interventions consistently demonstrated evidence in patients’ satisfaction, high level of user acceptance, and reduced use of health resources and cost savings to health care services. However, there is a lack of studies evaluating safety, organizational, sociocultural, ethical, and legal aspects of mHealth technologies. Furthermore, a comprehensive cost-effectiveness and cost-benefit analysis of adopting mHealth technologies was not found in the literature. Conclusions The gaps identified in this study will inform the creation of health policies and organizational support for mHealth implementation in patients undergoing dialysis. The findings of this review will inform the development of a comprehensive service model that utilizes mHealth technologies for home monitoring and self-management of patients undergoing chronic dialysis.

Abstract (sommario):

Several systems integration proposals have been suggested over the years. However these proposals have mainly focused on data integration, not allowing users to take advantage of services offered by Web portals. Most of the mentioned proposals only provide a set of design principles to build integrated systems and lack in suggesting a systematic way of how to develop systems based on the integration architecture they propose. In previous work we have developed PISA (Web Portal Integration Architecture)—a Web portal integration architecture for data and services—and MIDAS-S, a methodological approach for the development of integrated Web portals, built according to PISA. This work shows, by means of a case study, how both proposals fit together integrating Web portals.

Abstract (sommario):

The sharing economy has become a new socioeconomic activity that allows the co-creation, production, distribution and consumption of goods and services between individuals, driven by Web 2.0 and e-word of mouth. How these online platforms communicate their content is critical. This paper seeks to develop a scale for measuring the perceived quality of websites that offer information about sharing economy services focused on online peer-to-peer accommodation. The resulting model is validated by means of structural equations and is composed of four dimensions (efficiency; reliability, privacy/security; and communication). The influence that perceived quality exerts on satisfaction and loyalty is then explored from an online media perspective. A scale resulting from the combination of these two areas of knowledge (online media and e-service quality) may take advantage of the more beneficial features they have to offer and provide us with as balanced and convergent a model as possible. The results of the study show that all of the initial hypotheses are confirmed except one. Efficiency, reliability and privacy/security positively influence the perceived quality of a collaborative accommodation portal, whereas communication does not.

Abstract (sommario):

This paper describes an open educational resources (OER) architecture framework that would bring significant improvements in a well-structured and systematic way to the educational practices of distance education institutions of India. The OER architecture framework is articulated with six dimensions: pedagogical, technological, managerial, academic, financial, and ethical. These dimensions are structured with the component areas of relevance: IT infrastructure services, management support systems, open content development and maintenance, online teaching-learning, and learner assessment and evaluation of the OER architecture framework. An OER knowledge and information base, including a web portal, is proposed in the form of a series of knowledge repositories. This system would not only streamline the delivery of distance education but also would enhance the quality of distance learning through the development of high quality e-content, instructional processes, course/programme content development, IT infrastructure, and network systems. Thus the proposed OER architecture framework when implemented in the distance education system (DES) of India would improve the quality of distance education and also increase its accessibility in a well-organised and structured way.

Abstract (sommario):

Purpose – This paper aims to present an exploration of the potential utilisation of different information and communication technologies (ICT) in Indian academic libraries. Design/methodology/approach – A survey method was used for the collection of data. A structured questionnaire, containing close-ended questions, was sent by postal mail to 30 librarians of the Central University Libraries in India, of which 15 questionnaires were returned. Findings – Academic libraries in India have mostly been involved in applying traditional ICT-based solutions for the management of various library functions and services, particularly for organising and retrieving information. Use of modern ICT-based tools of knowledge creation and sharing such as web discovery tools, blogs, wikis, Real Simple Syndication feeds, social networking and social bookmarking seems uncommon in academic libraries. Lack of trained staff in ICT, low level of ICT skills among library users, unawareness of potential benefits of ICT and inadequate ICT infrastructure were found as the major barriers of ICT applications in academic libraries. Practical implications – Academic libraries in India are still in the early stage of understanding the importance of modern ICTs. Librarians should renovate existing library environment and develop knowledge and skills among their staff in the fields of computer programming, website or portal development, hardware maintenance and metadata or e-resource management for providing quality information services to their users. Originality/value – Because no empirical study on the use ICT-based knowledge management (KM) tools in academic libraries in India has been carried out before, this study closes this gap and provides guidelines for practising librarians, policy makers, management and the University Grants Commission of India to promote the use of ICTs in libraries, and to design courses of information communication technology and related skills.

Abstract (sommario):

Objective HealthPathways (HPW) is an international web-based information portal that provides health practitioners with guidelines and referral pathways to specialists and services. The present study explored usage of HPW by general practitioners (GPs) in the Barwon region, south-west Victoria, and any benefits and barriers to its use. Methods Approximately 421 GPs provide services in 86 clinics across the Barwon region, south-west Victoria and Barwon Health is the public health service providing acute, subacute, residential aged care and community health services to approximately 350000 people. The present study was a mixed-methods analysis of all GPs in the region, who were invited to complete a survey in two waves (2014 and 2016) and participate in focus groups. Data were survey/questionnaire (fixed response and free text options, analysed with descriptive statistics and content analysis), and focus groups (interview and facilitated group discussion, analysed using the principles of thematic analysis). Results Most GPs surveyed used HPW and usage increased over time from 2014 to 2016 (67% vs 77% respectively). Junior GPs used HPW more often than the more experienced practitioners. GPs reported that HPW was easy to access and navigate, improved their knowledge of local services, improved their confidence, changed their clinical management and saved them time. Main barriers to use of HPW were: GPs did not think to look at HPW, or simply did not know about it. Conclusions HPW has the potential to improve patient management and health outcomes, and use of HPW is increasing over time. What is known about the topic? Initiatives such as HPW are viewed positively by clinicians and have the potential to address challenges at the primary–secondary care interface, specifically, referral to secondary specialists. What does this paper add? Proof of concept that the ongoing availability of localised HPW for common clinical conditions improves GP usage of HPW and has increased access to HPW as the first source of clinical information. Benefits and barriers to use have been identified. What are the implications for practitioners? HPW improves knowledge of local services and provides GPs with easy access to referral pathways.

Background With increased specialization of health care services and high levels of patient mobility, accessing health care services across multiple hospitals or clinics has become very common for diagnosis and treatment, particularly for patients with chronic diseases such as cancer. With informed knowledge of a patient’s history, physicians can make prompt clinical decisions for smarter, safer, and more efficient care. However, due to the privacy and high sensitivity of electronic health records (EHR), most EHR data sharing still happens through fax or mail due to the lack of systematic infrastructure support for secure, trustable health data sharing, which can also cause major delays in patient care. Objective Our goal was to develop a system that will facilitate secure, trustable management, sharing, and aggregation of EHR data. Our patient-centric system allows patients to manage their own health records across multiple hospitals. The system will ensure patient privacy protection and guarantee security with respect to the requirements for health care data management, including the access control policy specified by the patient. Methods We propose a permissioned blockchain-based system for EHR data sharing and integration. Each hospital will provide a blockchain node integrated with its own EHR system to form the blockchain network. A web-based interface will be used for patients and doctors to initiate EHR sharing transactions. We take a hybrid data management approach, where only management metadata will be stored on the chain. Actual EHR data, on the other hand, will be encrypted and stored off-chain in Health Insurance Portability and Accountability Act–compliant cloud-based storage. The system uses public key infrastructure–based asymmetric encryption and digital signatures to secure shared EHR data. Results In collaboration with Stony Brook University Hospital, we developed ACTION-EHR, a system for patient-centric, blockchain-based EHR data sharing and management for patient care, in particular radiation treatment for cancer. The prototype was built on Hyperledger Fabric, an open-source, permissioned blockchain framework. Data sharing transactions were implemented using chaincode and exposed as representational state transfer application programming interfaces used for the web portal for patients and users. The HL7 Fast Healthcare Interoperability Resources standard was adopted to represent shared EHR data, making it easy to interface with hospital EHR systems and integrate a patient’s EHR data. We tested the system in a distributed environment at Stony Brook University using deidentified patient data. Conclusions We studied and developed the critical technology components to enable patient-centric, blockchain-based EHR sharing to support cancer care. The prototype demonstrated the feasibility of our approach as well as some of the major challenges. The next step will be a pilot study with health care providers in both the United States and Switzerland. Our work provides an exemplar testbed to build next-generation EHR sharing infrastructures.

Abstract (sommario):

This paper analyses the use and management of web portals of the Czech industries. This paper investigates which industries have the highest shares of foreign language portals. This share is compared to the number of hired IT professionals. This paper is based on the thesis that competing in global markets requires skilled labour force in the form of IT specialist. The analysis will be split into two parts because the management of web portals can be done in-house or outsourced. The statistical evaluation will be based on the contingency table analysis and detailed summary statistics. Foreign language web portals are essential to world market opportunities. Czech labour market provides only a limited number of IT specialist to hire. Results suggest that there are differences between industries (services, trade, manufacturing) in the management of web portals (in-house vs. outsourcing) and the number of IT specialist depends on the use of foreign language web portals. The outsourcing of international management of web portals or joining the global value chains is starting to be a more affordable and interesting option because the labour costs of IT specialist are raising in the Czech labour market.

Abstract (sommario):

Current e-Health portal platforms provide support for patients only if they have previously registered and received service from a healthcare facility (e.g., hospital, healthcare clinic, etc.). These portals are usually connected to a central EMR/EHR system linked to a central system. Furthermore, these portals are restrictive in that they are only accessible by these patients at the exclusion of parents, relatives and others that participate in providing care to the patient. Further complications include the increasing demand from our healthcare systems for patients to receive more off-site, non-primary, in-homecare, and/or specialized healthcare services at home (e.g., therapy, nursing, personal support, etc.). Lastly, an increasing number of people would like to have more autonomy over their health in terms of increased access to their own medical records and the services they receive. In this work, we addressed these limitations by creating MyHealthPortal – a patient portal aimed at non-primary care, in-homecare, and/or special healthcare for patients. MyHealthPortal can assist homecare and clinic-based healthcare services along with the benefits of existing portals (e.g., online appointment scheduling, monitoring, and information sharing). MyHealthPortal is secure, robust, flexible and user-friendly. We developed it in partnership with our industry partner, Closing the Gap Healthcare. Closing the Gap is a prominent homecare and clinic-based healthcare service provider that became the first homecare agency to score 100% on standards from accreditation Canada and was awarded the exemplary standing. In this paper we present MyHealthPortal, the architectural framework that we designed and developed to support the system, and the results of a usability study conducted from real field studies. Our system was tested in a variety of conditions and achieved SUS usability scores of 92.5% (high).

Abstract (sommario):

Research portals are a means to present, discuss, and advance scientific findings. They are web-based knowledge management tools for research communities. Research portals foster collaboration among a community of scientists, research funders, and political decision-makers. However, research communities might not possess the knowledge and experience required to design a research portal. The authors support them by analyzing the status quo of existing portals and providing respective improvement perspectives. The authors ask what typical characteristics of such portals are and how these characteristics can be used to evaluate the advancement of individual portals and they seek to distinguish classes of differently advanced research portals and determine their status quo. The authors’ research is based on a systematic web search, during which the authors identify 813 relevant research portals. Following a multi-method approach, they assign each research portal a previously distinguished class of advancement. The authors conclude that research portals generally only offer basic functionality and discuss functionality that is underrepresented in this pool of analyzed research portals and elaborate on improvement perspectives in 11 feature dimensions.

Abstract (sommario):

E-Government emerges from web sites that offer static information, documents and forms for employees and citizens, enquiries, and process automations to many types of stakeholders. Increasingly, different layers of government services are being consolidated into a knowledge portal, providing on time and online services. Such knowledge portals not only provide a platform for integrating applications and information from all government sources, but also provide platforms for knowledge sharing and learning to the public with the objective to improve the efficiency and the quality of E-Government processes and services. However, due to the heterogeneity of applications and information across different levels of government agencies, a significant amount of work is needed to re-configure such applications and services into a new platform. However, semantics are often deficient, which results in problems establishing effective knowledge sharing and learning in E-Government. This paper confers how knowledge intensive portals can be used for enhancing sharing and learning in E-Government. The authors discuss innovative information on how the Semantic Web and Web 2.0 technologies can be applied in providing interoperability to leverage knowledge sharing and learning activities.

Abstract (sommario):

Purpose Triggered by the advancement of information and communications technology, open access repositories (a variant of digital libraries) is one of the important changes impacting library services. In the context of openness to a wider community to access free resources, Wawasan Open University Library initiated a research project to build open access repositories on open educational resources. Open educational resources (OER) is an area of a multifaceted open movement in education. The purpose of this paper is to show how two web portal repositories on OER materials were developed adopting a Japanese open source software, called WEKO. Design/methodology/approach The design approach is based on a pull to push strategy whereby metadata of scholarly open access materials kept within the institution and network communities’ digital databases were harvested using the Open Archives Initiatives Protocol for Metadata Harvesting method into another open knowledge platform for discovery by other users. Findings Positive results emanating from the university open access repositories development showed how it strengthen the role of the librarian as manager of institutional assets and successfully making the content freely available from this open knowledge platform for reuse in learning and teaching. Research limitations/implications Developing further programmes to encourage, influence faculty members and prospective stakeholders to use and contribute content to the valuable repositories is indeed a challenging task. Originality/value This paper provides insight for academic libraries on how open access repositories development and metadata analysis can enhance new professional challenges for information professionals in the field of data management, data quality and intricacies of supporting data repositories and build new open models of collaboration across institutions and libraries. This paper also describes future collaboration work with institutions in sharing their open access resources.

Abstract A modern urban lifestyle can be a risk factor for developing non-communicable diseases and mental health problems (Eckert S, Kohler S. Urbanization and health in developing countries: A systematic review. World Health Popul. 2014;15:7–20; Penkalla AM, Kohler S. Urbanicity and mental health in Europe: a systematic review. Eur J Ment Health 2014;9:163–77). Two non-commercial, state-funded web portals in the German states of Berlin and Brandenburg are attempting to support the residents in realizing a healthier lifestyle. The initial portal is named Präventionsatlas [Atlas of Prevention] and has existed since 2008. The second portal, called Stadtplan Gesundheitsförderung [Health Promotion Map], went online in 2014 and has become the successor to the former. Both web portals provide health information as well as searchable databases with locally available health promotion courses and projects. Since internet portals and knowledge management through Internet portals have become more and more frequently used as public health tools (see, e.g. Quinn E, Huckel-Schneider C, Campbell D, Seale H, Milat AJ. How can knowledge exchange portals assist in knowledge management for evidence-informed decision making in public health?

Abstract (sommario):

Cloud Computing is a constantly evolving IT generic term used to refer to various IT solutions and services provided via the internet. Precisely, cloud computing can be said to be Â theÂ delivery of scalable IT resources over the Internet, as opposed to hosting and operating those resources locally; these resources can include applications and services, as well as the infrastructure on which they operate (EDUCAUSE 2009). So instead of spending money on applications and hardware, individuals and businesses have access to same resources without the commitment of ownership to vendors who provide on-demand services such as Customer Relationship Management (CRM), off-site storage, hosted email solutions, secure web portals, etc. Despite some seemingly security challenges that confront total adoption of Cloud computing by business organizations and educational institutions, the benefits of using services provided by Cloud technology still outweigh the perceived challenges. It is the aim of this paper to present an expository review of services that can run on the cloud thereby providing excellent opportunities for business groups and academics institutions. The paper also provides a contribution to the propagation of the adoption of cloud technology.

Most of the international e-Government benchmarking studies have focused on national government websites such as portal of ministries at the national level. This paper examines the level of sophistication of e-Government websites for different states in Malaysia, as opposed to a national level assessment, both in terms of the breadth and depth of e-Government service offering. This paper adds to the existing body of knowledge in relation to e-Government web portal assessment in two ways. First, studies pertaining to e-Government in Malaysia focus mainly on implementation issues at the Federal/National level– The authors examined State level implementation of e-Government services. Secondly, they used a predetermined instrument to assess the sophistication level of State government web portals, by consolidating different measurement items from our review of literature over the past ten years. The authors analyzed the website for a total of thirteen states in Malaysia, in relation to six different dimension measures of e-Government service offerings, as prescribed by literature. These six dimension measures are the extent of transparency, interactivity, usability and accessibility of the portal, citizen participation, security and privacy, and maturity level of services. A content analysis of the web portal was done, using a predetermined instrument developed based on our review of literature on this topic, in the past ten years. Their findings suggest that different State Governments in Malaysia demonstrate different levels of maturity in relation to the six dimensions measured.

Abstract (sommario):

The paper presents the approach to Internet knowledge portals design based on ontologies. Internet knowledge portals provide users with access to heterogeneous loosely coupled data and information resources of various subject domains. Using such portals as a single access point greatly simplifies the work with information presented on the Internet. In the case of Internet portals representing engineering subject domains information their environment concentrate not only information resources and data, but also a large number of computing resources and web-services that are used to perform certain calculation tasks of engineering subject domains. The ontological approach to Internet knowledge portals design allows to represent and integrate heterogeneous information and computing resources in the process of such portals data and knowledge structuring and systematizing. It is proposed to use ontology as portal knowledge representation model. The Internet knowledge portal general ontology is represented by a system of four interconnected components. The structure of such a system is described, the basic elements of its ontologies, as well as the relations between them, are distinguished. The ontology elements are formalized that allows to organize and optimize semantic search through the Internet knowledge portals information space.

Abstract (sommario):

The increased use of smartphones and tablets, along with advanced security features being offered by the online retailers are adding strength to e-commerce industry. Growing at an astonishing rate at 85%, as against 65% growth of regular shopping over the previous year, internet retailing in India touched US $10.672 billion in 2013, making it one of the most anticipated destinations for national and multinational online retailers. Several web portals are looking to capture a share of this huge market. This study gains importance as Indian arms of multinational online selling companies like Amazon and eBay are fighting various home-grown players like Snapdeal, Flipkart and many more. The objective of this paper is to identify and rank the factors that influence the selection of web portal among online shoppers in India. Exploratory study was conducted to identify various precursors of web site selection for online shopping. Twenty-four variables identified from this study were used to create a structured questionnaire. This questionnaire was then administered among 203 shoppers in India using convenience sampling. To determine the factors that influence the selection of web portals. Principal Component Analysis with Varimax Rotation was used. The study condensed the comprehensive set of twenty-four variables into six factors that have a direct influence on consumers' choice of online buying website. These were transaction security, augmented benefits, user experience, cognitive stimuli, personalized assurance and web atmospherics. This is against the general perception that shoppers prefer the web portals with best user experience and attractive web atmospherics. The online buying population of the world's third largest economy selects the portals based on the primary motive of security in a transaction. Adding to the existing knowledge on shoppers' selection of online buying portals, the study reveals the prevalence of a multitude of antecedent factors and distinct patterns with respect to constituents of these factors. Findings of this research may be used as guidelines for the development of multi-dimensional strategic framework by online retailing firms.

Abstract (sommario):

The use of Web services as a means of dynamically discovering, negotiating, composing, executing and managing services to materialize enterprise-scale workflow is an active research topic. Existing approaches involve many disparate concepts, frameworks and technologies. What is needed is a comprehensive and overarching framework that handles the processing and workflow requirements of Virtual Organizations, maps them to a collection of service-oriented tasks, dynamically configures these tasks from available services, and manages the choreography and execution of these services. The goal is to add semantics to Web services to endow them with capabilities needed for their successful deployment in enterprise-scale systems for Virtual Organizations. This paper introduces such a framework, the Knowledge-based Dynamic Semantic Web Services (KDSWS) Framework that addresses in an integrated end-to-end manner, the life-cycle of activities involved in preparing, publishing, requesting, discovering, selecting, configuring, deploying, and delivering Semantic Web Services. In particular, the following issues are addressed with an emphasis on adaptability to rapidly changing environments and standards: (1) semantic specification of both service's and requestor's capabilities, constraints and preferences including quality of service, trust, and security; (2) transaction control and workflow management; and (3) resource management, interoperation and evolution of the Virtual Organization.

Abstract (sommario):

The emerging Semantic Web and, in particular, Semantic Web services (SWS), demands the inclusion of new components in applications involving this technology. Therefore, Web development methodologies must be tailored to support the systematic development of such new components. In previous works we presented a UML profile, which extends the SOD-M method for service oriented Web Information System development of the MIDAS model-driven framework, to address the development of Semantic Web Services using WSMO (Web Service Modeling Ontology). The UML profile allows for the modeling of the new elements required by WSMO Web Services. This article focuses on studying the possibility of improving the proposed UML profile, including the OCL (Object Constraint Language), for the representation of WSMO logical axioms through three case studies. This would allow developers, whose knowledge does not extend beyond UML, to develop applications that use Semantic Web services.

Abstract (sommario):

Web APIs (Application Programming Interface) are a common means for Web portals and data producers to enable HTTP-based, machine-processable access to their data. They are a prominent source of information*1 pertaining to topics as diverse as scientific information, social networks, entertainment or finance. The methods of Linked Data (Heath and Bizer 2011) similarly aim to publish machine-readable data on the Web, while connecting related resources within and between datasets, thereby creating a large distributed knowledge graph. Today, the biodiversity community is increasingly adopting the Linked Data principles to publish data such as trait banks, museum collections and taxonomic registers (Parr et al. 2016, Baskauf et al. 2016). However, standard approaches are still missing to combine disparate representations coming from both Linked Data interfaces and the manifold Web APIs that were developed during the last two decades to expose legacy biodiversity databases on the Web. The SPARQL Micro-Service architecture (Michel et al. 2018) tackles the goal of reconciling Linked Data interfaces and Web APIs. It proposes a lightweight method to query a Web API using SPARQL (Harris and Seaborne 2013), the Semantic Web standard to query knowledge graphs expressed in the Resource Description Framework (RDF). A SPARQL micro-service provides access to a small RDF graph, typically resource-centric, that it builds at run-time by transforming a fraction of the whole dataset served by the Web API into RDF triples. Furthermore, Web APIs traditionally rely on internal, proprietary resource identifiers that are unsuited for use as Uniform Resource Identifiers (URIs). To address this concern, a SPARQL micro-service can assign a URI to a Web API resource, allowing an application to look up this URI and get a description of the resource in return (this process is referred to as dereferencing). In this demo, we wish to showcase the value of SPARQL micro-services in the biodiversity domain. We first query TAXREF-LD, a Linked Data representation of the French taxonomic register of living beings (Michel et al. 2017), to retrieve information about a given taxon. Then, we demonstrate how we can enrich our knowledge about this taxon with various types of data retrieved on-the-fly from multiple Web APIs: trait data from the Encyclopedia of Life trait bank (Parr et al. 2016), articles or books from the Biodiversity Heritage Library, audio recordings from the Macaulay scientific media archive, photos from the Flickr photography social network, and music tunes from MusicBrainz. Different visualizations are demonstrated, ranging from raw RDF triples to Web pages generated dynamically and integrating heterogeneous data, as suggested in Fig. 1. Depending on the audience’s interests, we shall touch upon the alignment of Web APIs’ proprietary vocabularies with well-adopted thesauri or ontologies, or more technical concerns e.g. related to the effort required to deploy a new SPARQL micro-service.

Abstract (sommario):

The continually expanding distributed global compendium of biomedical knowledge is diffuse, heterogeneous and huge, posing a serious challenge for biomedical researchers in knowledge harvesting: accessing, compiling, integrating and interpreting data, information and knowledge. In order to accelerate research towards effective medical treatments and optimizing health, it is critical that efficient and automated tools for identifying key research concepts and their experimentally discovered interrelationships are developed. As an activity within the feasibility phase of a project called “Translator” (https://ncats.nih.gov/translator) funded by the National Center for Advancing Translational Sciences (NCATS) to develop a biomedical science knowledge management platform, we designed a Representational State Transfer (REST) web services Application Programming Interface (API) specification, which we call a Knowledge Beacon. Knowledge Beacons provide a standardized basic API for the discovery of concepts, their relationships and associated supporting evidence from distributed online repositories of biomedical knowledge. This specification also enforces the annotation of knowledge concepts and statements to the NCATS endorsed the Biolink Model data model and semantic encoding standards (https://biolink.github.io/biolink-model/). Implementation of this API on top of diverse knowledge sources potentially enables their uniform integration behind client software which will facilitate research access and integration of biomedical knowledge. Availability The API and associated software is open source and currently available for access at https://github.com/NCATS-Tangerine/translator-knowledge-beacon.

Abstract (sommario):

This paper presents an approach to enhance various intelligent services of a Web-based collaborative knowledge management system. The proposed approach applies the two widely-used argumentation technologies, namely IBIS and Toulmin’s argumentation schemes, to structurally capture the deliberation and collaboration occurred during the consensual knowledge creation process. It employs RDF and OWL as its underlying knowledge representation language with well-defined semantics and reasoning mechanisms. Users can easily create knowledge using a simple corresponding graphical notation with machine-processable semantics. Derivation of implicit knowledge, similar concept discovery, as well as semantic search, are also enabled. In addition, the proposed approach incorporates the term suggestion function for assisting users in the knowledge creation process by computing the relevance score for each relevant term, and presenting the most relevant terms to users for possible term reusing or equivalence concepts mapping. To ensure the knowledge consistency, a logical mechanism for validating conflicting arguments and contradicting concepts is also developed. Founded on the proposed approach, a Web-based system, namely ciSAM, is implemented and available for public usage.

Abstract (sommario):

Aiming at implementing knowledge reusability and high efficiency in the design process, this paper brings up a knowledge-based web service environment for 3D visualization (KWSE). KWSE proposes clearly: encapsulating geometry APIs to web services, knowledge fusion process and knowledge database management. To implement the construction it forms knowledge service model and knowledge-driven web service architecture. Following this architecture, a knowledge-driven 3D visualization system has been built using Open CASCADE geometry engine and WISF technology.

Abstract (sommario):

We describe best practices for providing convenient, high-speed, secure access to large data via research data portals. We capture these best practices in a new design pattern, the Modern Research Data Portal, that disaggregates the traditional monolithic web-based data portal to achieve orders-of-magnitude increases in data transfer performance, support new deployment architectures that decouple control logic from data storage, and reduce development and operations costs. We introduce the design pattern; explain how it leverages high-performance data enclaves and cloud-based data management services; review representative examples at research laboratories and universities, including both experimental facilities and supercomputer sites; describe how to leverage Python APIs for authentication, authorization, data transfer, and data sharing; and use coding examples to demonstrate how these APIs can be used to implement a range of research data portal capabilities. Sample code at a companion web site, https://docs.globus.org/mrdp, provides application skeletons that readers can adapt to realize their own research data portals.

Abstract (sommario):

Online offerings such as web search, news portals, and e-commerce applications face the challenge of providing high-quality service to a large, heterogeneous user base. Recent efforts have highlighted the potential to improve performance by introducing methods to personalize services based on special knowledge about users and their context. For example, a user's demographics, location, and past search and browsing may be useful in enhancing the results offered in response to web search queries. However, reasonable concerns about privacy by both users, providers, and government agencies acting on behalf of citizens, may limit access by services to such information. We introduce and explore an economics of privacy in personalization, where people can opt to share personal information, in a standing or on-demand manner, in return for expected enhancements in the quality of an online service. We focus on the example of web search and formulate realistic objective functions for search efficacy and privacy. We demonstrate how we can find a provably near-optimal optimization of the utility-privacy tradeoff in an efficient manner. We evaluate our methodology on data drawn from a log of the search activity of volunteer participants. We separately assess users preferences about privacy and utility via a large-scale survey, aimed at eliciting preferences about peoples willingness to trade the sharing of personal data in returns for gains in search efficiency. We show that a significant level of personalization can be achieved using a relatively small amount of information about users.

Abstract (sommario):

E-finance industry is rapidly transforming and evolving toward more dynamic, flexible and intelligent solutions. This paper describes a model with dynamic multilevel workflows corresponding to a multilayer Grid architecture. The mining-grid is used for multiaspect analysis in building e-finance portals on the Wisdom Web. The application and research demonstrate that mining-grid centric design is effective for developing intelligent risk management and decision making financial systems. This paper concentrates on how to develop a mining-grid centric e-finance portal (MGCFP), not only for supplying effective online financial services for both retail and corporate customers, but also for intelligent credit risk management and decision making for financial enterprises and partners.

Abstract (sommario):

The authors propose a Web-Mashup Application Service Framework for Multivariate Time Series Analytics (MTSA) that supports the services of model definitions, querying, parameter learning, model evaluations, data monitoring, decision recommendations, and web portals. This framework maintains the advantage of combining the strengths of both the domain-knowledge-based and the formal-learning-based approaches and is designed for a more general class of problems over multivariate time series. More specifically, the authors identify a general-hybrid-based model, MTSA – Parameter Estimation, to solve this class of problems in which the objective function is maximized or minimized from the optimal decision parameters regardless of particular time points. This model also allows domain experts to include multiple types of constraints, e.g., global constraints and monitoring constraints. The authors further extend the MTSA data model and query language to support this class of problems for the services of learning, monitoring, and recommendation. At the end, the authors conduct an experimental case study for a university campus microgrid as a practical example to demonstrate our proposed framework, models, and language.

Abstract (sommario):

This paper explores the ways in which Indigenous people around the world are participating in the World Wide Web, through establishing their own websites or accessing services via the Web. Indigenous websites are remarkably diverse: in addition to those representing Indigenous organizations and promoting Indigenous e-commerce, many websites have also been established to further unique concerns of Indigenous communities such as the maintenance and revitalization of Indigenous cultures, intercultural dialogue between Indigenous and non-Indigenous people, political advocacy and mobilization, community rebuilding and social support for disadvantaged communities. Despite the early involvement of Indigenous people on the Web, there still remain many unresolved issues, which include low levels of computer literacy and Internet connectivity, the cost of the technology, low levels of business understanding to support e-commerce, and concerns over the misappropriation of Indigenous knowledge and culture.

Abstract (sommario):

Purpose – Research into professional services firms that have successfully implemented and adopted Web 2.0 tools are still rare, with no widely known accepted methodologies or frameworks. The purpose of this case study is to investigate a medium-sized law firm that embarked on a KM programme that makes explicit use of emergent enterprise-based Web 2.0 tools. Design/methodology/approach – The overlying research methodology applied is action research, in particular participatory action research (PAR). The study draws on interviews with practitioners, consultants and knowledge workers and takes into consideration multiple stakeholder views and value conflicts. The project is part of a Knowledge Transfer Partnership between RPC LLP and Westminster Business School. Findings – Implementation of Web 2.0 tools in professional services requires the blending of a number of approaches to address the intrinsic tension between the open, participative behaviour and iterative development methodologies encouraged by social tools, and more traditional management styles and methods of developing IT solutions. Research limitations/implications – This article presents a single case study based on a law firm that, at the start of the research, was operating from a single location in London and at the time of writing has expanded to multiple locations, including overseas. There may be a limitation to implementing lessons learned and methodologies to larger organisations and organisations outside the legal sector. Originality/value – While many organisations are still attempting to understand how they can practically implement Web 2.0 tools, this case study presents findings from a law firm that has had an internal Web 2.0-based knowledge solution in place for over two years. The research also makes use of a KM maturity model in order to assess the impact of the Web 2.0 implementation.

Abstract (sommario):

Purpose – The purpose of this paper is to increase understanding of the role of information and knowledge in the context of health behaviour change. Design/methodology/approach – As internet use in Finland is among the highest in Europe, two Finnish web-based weight management services were analysed regarding their weight maintenance information by using a theoretical approach constructed for the purpose. The approach combines the elements of web-based weight maintenance information and the typologies of knowing and actional information. The approach was tested by examining the services deductively with theory-based content analysis. Findings – The approach indicated differences between the profiles of the two analysed information environments, which focus on factual and tailored information and their relation to pragmatic, provisional and contested knowing and the initiation, maintenance and recovery of actional information. Both services support weight maintenance; the other slightly more due to its rich social features. Research limitations/implications – The examination was focused on the free content of two Finnish weight management services. Further research should include the role of socially interactive information and further testing of the approach with more services. Practical implications – The proposed approach sheds light on the relationship between the types of weight maintenance information and the dimensions of the typologies of knowing and actional information. The approach has the potential to be applied when designing the information environment of new web-based weight management services. Social implications – The approach has potential to be applied when designing the information content of new web-based weight management services to support health behaviour change. The approach could be elaborated further by focusing on enabling social support required in long-term weight maintenance. Originality/value – The study adopted a novel approach to studying typologies of knowing and actional information, thus providing new viewpoints in both information behaviour and organisational knowledge. The study enables further research on weight maintenance information use by proposing a theoretical background.

Abstract (sommario):

Abstract. Spatio-temporal big data cloud platform is an important spatial information infrastructure that can provide different period spatial information data services, various spatial analysis services and flexible API services. Activities of policy coordination, facilities connectivity and unimpeded trade on the Belt and Road Initiative (B&R) will create huge demands to the spatial information infrastructure. This paper focuses on researching a distributed spatio-temporal big data engine and an extendable cloud platform framework suits for the B&R and some key technologies to implement them. A distributed spatio-temporal big data engine based on Cassandra&trade; and an extendable 4-tier architecture cloud platform framework is put forward according to the spirit of parallel computing and cloud service. Four key technologies are discussed: 1) a storage and indexing method for distributed spatio-temporal big data, 2) an automatically collecting, processing, mapping and updating method of authoritative spatio-temporal data for web mapping service, 3) a schema of services aggregation based on nodes registering and services invoking based on view extension, 4) a distributed deployment and extension method of the cloud platform. We developed a distributed spatio-temporal big data centersoftware and founded the main node platform portal with MapWorld&trade; map services and some thematic information services inChina and built some local platform portals for those countries in the B&R area. The management and analysis services for spatio-temporal big data were built in flexible styles on this platform. Practices show that we provide a flexible and efficient solution tobuild the distributed spatio-temporal big data center and cloud platform, more node portals can be aggregated to the main portal bypublishing their own web services and registering them in the aggregation schema. The data center and platform can support thestorage and management of massive data well and has higher fault tolerance and better scalability.
