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):
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):

With the proliferation of Internet, ERP systems like all the domains of Information Technology have known an important evolution. This final thesis project is a study about the evolution of ERP systems, more precisely about their migration to the Web giving birth to a new generation of systems: the Web-Based or Web-enabled ERP systems. This migration to the Web is justified by the difficulty of making possible the communication between partner’s legacy systems and the organizations’ ERP systems. A historical evolution of these systems is presented in order to understand the reasons that lead vendors to adopt the Web Service Technology. Based on different studies, the main technologies such as Web services, Service-Oriented Architecture and Web Application server are also presented. From an interpretative research approach mySAP ERP has been chosen as a case study. This Master’s thesis has been led into AIRBUS France Company within the framework of the SAP Customer Competence Center (SAPCCC) Web site project. The project is aimed at re-building the SAPCCC Web site. The new characteristic of the Web site is to make it accessible by all AIRBUS partners working with SAP applications. To make the Web site accessible by the partners from their own applications located on their own platforms the development has been done thanks to mySAP ERP which is an ERP using the Web service technology. Finally, this thesis presents a comparative study between traditional ERP systems and the new generation of Web-based ERP systems.

Abstract (sommario):
O acúmulo de documentos disponíveis na Web dificulta a recuperação de informação e a gestão eficiente do conhecimento. Os modelos tradicionais de recuperação da informação são inadequados para uma busca efetiva e rápida, e os resultados são, comumente, numerosos e irrelevantes. Com o advento da Web Semântica foi possível o uso da ontologia formal como modelo de recuperação da informação na Web para melhorar a qualidade da informação recuperada. Os portais semânticos constituem um instrumento da Gestão do Conhecimento que oferece maior capacidade e rapidez no acesso às informações com relevância dos resultados. Neste sentido, esta pesquisa tem como objetivo propor condições mínimas necessárias para o estabelecimento de potencial semântico de portais, mediante o mapeamento do uso da ontologia como modelo de recuperação da informação. O locus da pesquisa incluiu os portais de universidades públicas federais brasileiras da Região Sul do Brasil, partindo-se de um estudo comparativo entre as características da Web Semântica e as ferramentas e tecnologias usadas nas instituições pesquisadas. A pesquisa de campo foi instrumentalizada por um questionário, coletando-se dados da equipe técnica responsável pelos portais. Como principais resultados apresentam-se um diagnóstico do uso da ontologia na estruturação dos portais universitários pesquisados e a proposição de um quadro de referência das condições mínimas necessárias para estabelecimento de potencial semântico dos portais.
The accumulation of documents available on the Web makes it difficult to information retrieve and efficient knowledge management. Traditional models of information retrieval are inadequate for effective and quick search, and the results are often numerous and irrelevant. With the advent of the Semantic Web it was possible the use of formal ontology as a model of web information retrieval that improves the quality of the information retrieved. Semantic portals are a Knowledge Management tool that offers greater capacity and speed of access to information relevant results. In this trend, the goal of the this research is propose minimum conditions necessary for the establishment potential of semantic portals, by mapping the use of ontology as a model of information retrieval. The research's locus included the portals of federal public universities in southern Brazil, starting from a comparative study between the Semantic Web features and the tools and technologies used in the institutions surveyed. The field research was instrumentalized by a pool, collecting data from the technical team responsible for portals. The main results were presented a diagnosis of ontology in the structuring of respondents university portals and a framework of minimum conditions for semantic potential property portals.

Abstract (sommario):
La gestion des connaissances permet d'identifier et de capitaliser les savoirs faires de l'entreprise afin de les organiser et de les diffuser. Cette thèse propose un système de gestion des connaissances hétérogènes et distribuées, appelé OCEAN. Basé sur les ontologies et sur un système multi-agents, OCEAN a pour but de résoudre le problème de la capitalisation et de réutilisation des connaissances provenant de plusieurs sources différentes, afin d'aider les acteurs métiers dans le processus de développement de produits mécaniques. Le système OCEAN repose sur un cycle de vie de quatre étapes Ce cycle de vie possède les phases : d'identification, d'extraction, de validation et se termine par la réutilisation des connaissances. Chaque phase constitue l'objectif d'une organisation d'agents.L'identification dans le système OCEAN consiste à définir les connaissances par un expert métier sous la forme d'une ontologie. Les ontologies sont utilisées dans notre système pour représenter les connaissances définis d'une façon structurée et formelle afin d'être compréhensible par les machines. L'extraction des connaissances dans OCEAN est réalisée par les agents de manière automatique à l'aide des ontologies créées par les experts métiers. Les agents interagissent avec les différentes applications métiers via des services web. Le résultat de cette phase est stocké dans une mémoire organisationnelle. La validation des connaissances consiste à permettre aux acteurs métiers de valider les connaissances de la mémoire organisationnelle dans un wiki sémantique. Ce wiki permet de présenter les connaissances de la mémoire organisationnelle aux acteurs pour les réutiliser, les évaluer et les faire évoluer. La réutilisation des connaissances dans OCEAN est inspiré de travaux antérieurs intégrés au sein d'OCEAN. Les quatre phases du cycle de vie des connaissances traitées dans cette thèse nous ont permis de réaliser un système apte à gérer les connaissances hétérogènes et distribuées dans une entreprise étendue.

Abstract (sommario):
ppXML is an information infrastructure that enables and facilitates meaningful information and knowledge management within and interoperability between web services (applications) for Platform Product Development (PPD) — a formidable approach to agile product development (APD) for mass customization (MC). There are four folds of meanings in ppXML. Firstly, ppXML represents a set of constructs that are consistent with concepts and methods of Platform Product Development for Mass Customization. Secondly, derived from XML (eXtensible Markup Language) as a sublanguage, ppXML is a standard and yet extensible modeling language dedicated to the modelling of products and product platforms for PPD web services. Thirdly, ppXML serves as a product platform repository and a PPD web service registry, together with a set of online facilities for data representation and transformation between different components and parties involved in the web services. Finally, ppXML is a proof-of-theconcept online PPD portal, incorporating some essential web-based Decision Support Systems (DSS) for product platform development and product platform customization. This paper presents an overview of ppXML together with its background and underlying philosophy.
