In recent years, the number and size of Web services on the Internet have a rapid development. Industry and academia start to study the web service. In Internet resources, if the web cannot be found, the web service will become meaningless. So for web services, large-scale managements and problems are the keys of the study of Internet service resources. This paper studies large-scale distributed web services in network resources based on SOA architecture ideas. It also designs the unified management and organization system of ideological and political education which treat the ideological and political education as the content. It proposes SN network resource service model of ideological and political education. With the development and popularization of the Internet today, the study on Internet resources of ideological and political education in this paper provides a theoretical reference for the innovation of the ideological and political education.

Intelligent resource includes the knowledge, hardware and software resources even workflow and human resource, etc. From the point of view of enterprise information management, the service composition is an essential element for companies’ informatization construction. Therefore, the paper describes a web service composition framework for semantically-annotated web service. Based on the state of art ontology technology, an OWL-S process model for the CAM software is established to describe resource service. Then a service discovery process which mainly consists of services’ property matching algorithm for words is set up. A backward chaining framework for service composition is employed to dynamically compose resource services finally.

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.

In recent years, Cloud Computing has become popular to facilitate the use of Modeling and Simulation (M&S) resources. Nevertheless, there are still various issues to solve, including the structure constrain of chosen web service frameworks, the sharing of varied resources in the Cloud, and the difficulties in reproducing experiments. We show a new architecture based on Cloud Computing and new modeling methods to deal with these issues. This layered architecture, called Cloud Architecture for Modeling and Simulation as a Service (CAMSaaS), simplifies the deployment of M&S resources as services in the Cloud. CAMSaaS supports hierarchical resource services, experimental frameworks, scalable infrastructure and makes everything as a service. We deploy varied M&S resources as services in the Cloud, and build a Modeling and Simulation as a Service (MSaaS) middleware called CloudRISE to manage a variety of M&S resources. We also use the experimental framework concept to simplify the management of experiment environments. We present a case study for crowd evacuation application using the architecture.

Full textAbstract:
The CCP4 software suite [1] provides a comprehensive set of tools for use in the macromolecule structure solution process by X-ray crystallography. Traditionally, these tools have been run through the graphical interface or the command line on each user's personal workstation. Recently, some of the tools, including the molecular replacement pipelines Balbes [2] and MrBUMP [3] have been provided as web services in the Research Complex at Harwell. These pipelines can be especially useful in cases where there is low sequence identity between the target-structure sequence and that of its set of possible homologues. These services can be accessed through a web client, allowing one to submit molecular replacement jobs to our Linux cluster and view the results from these jobs. The molecular replacement pipelines are ideal candidates for web services, as they require installation and maintenance of large databases and benefit from parallel computing resources, provided by the cluster. Further plans for web services will be discussed. With ever-increasing mobility of scientific setups and the ubiquity of ultra-portable devices, there is a demand for a consistent framework of remote crystallographic computations and data maintenance. This framework is planned to include an interface for synchronising data with the facilities of Diamond Light Source, as well as with local CCP4 GUI-2 setups.

.As Web Services draw modules within and across enterprises, dynamically and belligerently testing Web Services has become crucial. Comprehensive Functional, Concert, Interoperability and Susceptibility Testing form the Pillars of Web Services Testing. Only by adopting a comprehensive testing department, enterprises can safeguard that their Web Services is robust, scalable, interoperable, and secure. Overall functionality of web services would be informal towards test. But, only if we methodically trust the applications components (services) before we combine them to complete the application. In current scenario web service technology comprehends various testing apparatuses for manipulating and generating the test cases. But these tools and approaches were negotiating security and execution time and consume more resources. The existing methodologies will generate test cases for the low end web services and limited number of requests, due to these constraints we built new testing framework. In this paper we introduced the new basis with testing of actions, scripts and link for web services by the use of test cases. For this approach we used SOAP web services with SOA. The test case generation and testing reports will gives the accurate testing results and test cases. These test cases are generated using Java JUnit testing tool. We implemented our approach in a java based platform for efficient and secure manner.

We propose a web service selection framework by introducing a QoS-based cost function concept. We used this mechanism to choose a few web services from a given service community according to their cost function. Then, we compose them together to find the optimal composite service. The proposed selection algorithms consume only limited system resources and have the characteristics of efficiency, dynamics, and fault tolerance. Hence, the aim is to optimally select component services at run time according to users' preferences and non-functional parameters.

Advantages and disadvantages of using cloud technologies in companies are considered. The programmatic mechanisms for protecting data and users’ resources from an unauthorized access that are given by an Amazon Web Services (AWS) cloud service provider are analyzed. The basic vulnerabilities which can be present even when effective programmatic methods for cloud resources safety exist are analyzed. Such problems as obsolescence of the access keys, open ports and untuned safety rules, presence of resources which are not in use in a cloud are highlighted. In the article approaches for increasing data protection strength and information security in the AWS cloud are proposed. Development of the framework is proposed, the main functions of this framework is the following: scanning and removing outdated access keys, open ports, resources which are not in use and vulnerable configurations of protection mechanisms in a cloud. For ease of use of the framework, it is supposed to develop scripts for automating the process of its deployment.

To support business and engineering collaboration in the diversified and global markets, enterprises are trying hard to continuously align their actual business processes to response customers’ demands. In this context, a flexible framework for inter-organizational process management is proposed, in which ontologies and semantic web service technologies are used throughout process modeling, implementation and execution. Heterogeneous manufacturing resources are encapsulated as uniform semantic web services, called manufacturing services, which are published, located and combined into executable processes. By means of formally definition of service capacity and as the mediation, business logic and implementation techniques is loosely coupling relationship, so enterprises can collaborate without prior relationship established and adjust their processes on demand.

Full textAbstract:
RESTful web services have evolved based on REST architectural design and gained popularity because of their inherent simplicity and suitability features in comparison with SOAP-based web services. Moreover, linked open data (LOD) provides a uniform data model for RESTful web services which in turn avoids manual intervention of users to perform tasks such as, searching, selection, and integration. Researchers have worked on LOD based RESTful web services searching, selection and composition but focused on individual basis though they are interrelated tasks. This article presents an integrated framework and approach to automate the discovery, selection and composition of RESTful Web services using linked open data to provide an efficient composition solution. We work with RDF descriptions to express the state of linked data resources on which SPARQL queries would be applied for the extraction, filtering and integration of RESTful services. Use case scenarios of population information systems and healthcare recommendation systems are presented as a proof of concept with necessary results.

Thanks to Web 2.0 technologies, many computer-supported activities are provided on-line, which enhances the possibility of sharing information and resources. In particular, the concept of service cloud is emerging as a paradigm for offering Web-based services based on an open distributed architecture. In this paper, the authors propose a framework supporting the management of Collaborative Service Clouds, i.e., open, Web-based environments that enable the integration of heterogeneous services, and provide a user-centered unified management of business and private activities. The management of Collaborative Service Clouds is enabled by an open architecture, which provides services and data synchronization, coupled with a set of core applications supporting essential aspects of the functionality of the environment.

This paper has pointed out the need for new technologies for integrating embedded devices in heterogeneous distributed networks, and outlines the perspectives opened by applying service-oriented paradigm for realizing interaction with embedded devices. As a foundation for interaction with embedded devices, XML and Web services have been used. Strong integration power of XML and Web services make presented framework appropriate for unique approach to all resources of embedded device regardless of applied technology. Developed Web services based middleware, provides application designers with a high level of semantic abstraction, hiding the complexity of the applied technologies. This makes presented framework suitable for use in many domains, independent of embedded devices physical realization or network characteristics. Two ways to achieve such integration have been presented in this paper: device level for modern embedded devices, and using service oriented gateway for "legacy" embedded systems. .

The development of mobile devices and the spread of wireless network help share and exchange information and resources more easily. Therefore users are able to use the information and service more free than previous wire network due to development of wireless network and device. In order to provide appropriate user services, it enables to recognize users current state, analyze the users profile like users tendency and preference, and draw the service answering the users request. Most existing frameworks, however, are not very suitable for mobile devices because they were proposed on the web-based. And other context information except location information among users context information is not much considered. Therefore, this paper proposed the context-aware framework, which provides more suitable services by using users context and profile.

SOAP/WSDL and REST are two architectural styles to build web services. SOAP/WSDL follows operation centric and REST follows resource centric approach. SOAP/WSDL has standard registry where producer can register service specification and consumer can discover service endpoint using UDDI. Recently RESTful web service gained momentum in development of distributed application and research community already started discussion about RESTful based Service Oriented Architecture(SOA) but there is no standard central repository exist where producer can register and consumer can search RESTful service based on Quality of Services or based on their specification. In this research paper, we proposed framework: XML based RESTRegistry – central repository with Quality of Service through which producer can easily register services and consumer can search it easily. We also developed Travel Schedule benchmark application to test proposed framework in real world.

The RESTful Web services is a lightweight framework which includes some important ideas such as addressability of resources, statelessness, connectedness, and uniform interface and has good interaction and elasticity by its loose coupling and other distributed components. In this paper, we aim at to solve the problem of information islands in the construction of Chinese medicine informatization and propose a valid scheme based on the techinque of RESTful Web Services. In accordance with the classification and cording of Chinese medicine provided by National Science Data Sharing Project, the difinition of information resources of Chinese medicine is first completed. In order to realize sharing and concordancy of Chinese medicine resources, a registration center is built so that Chinese medicine resources can be registered and released. Through reserching Restlet framework, an elementary Chinese medicine information system based on RESTful Web Services technique is obtained. Since distributed retrieval and sharing of Chinese medicine information is briefly relizied in this system, further research on how to intergrate the data resources will be continued.

Full textAbstract:
Geo-sensor is the term used for the deployment of a wireless sensor network (WSN) in a real environment, which can be a hideous task due to many influential variables in a given environment. The spatial context of a sensor in a smart environment can be of huge significance and can also play an important role in improving the smart services provision. In this work, we propose a DIY geo-sensor framework and data composition toolbox for the deployment of sensors data in smart IoT environments along with geographical context. A geo-sensor framework is deployed, which enables the registration of multiple geo-sensor networks by providing multiple geo-sensor platforms. The framework’s logic is based on the combination of a geo-sensor service registry, geo-sensor composition toolbox, and geo-sensor platforms. A geo-sensor platform provides the content to the toolbox, enabling relaxed real-time geo-sensor data management. Our proposed work is two-fold. Firstly, we propose the design details for the geo-sensor framework and composition toolbox. The proposed design for the geo-sensor framework aims to provide a DIY platform for multiple geo-sensor networks and services deployment, giving access to multiple users resulting in reuse of resources and reduction in deployment costs by avoiding duplicate deployments. Secondly, we implement the proposed design based on RESTful web services and SOAP web services. Performance comparison analysis is then performed among the two web services to find the best suited implementation for given scenarios. The results of the performance analysis prove that RESTful web services are the better choice for ease of implementation, access, and light-weightiness.

E-government presents a tremendous opportunity to provide higher quality, and cost-effective government services as well as creating a better relationship between citizens and government. The use of Web GIS makes the sharing and applying traditional GIS being possible. Web GIS provides integrated geo-spatial information and services to users and decision support for the government's macro decision-making. However, the current condition of huge initial capital investment in ICT equipment and IT labor does not change. As Cloud Computing enables sharing of resources and costs across a large pool of users while providing on-demand services with dynamic scalability. E-government with cloud computing raises the utilization rate of resource and reduces the budget. In addition, if e-government system is moved to cloud computing environment, cloud computing can construct the system into a service platform which takes service as its core, realizing the transition of government function and promoting the upgrading of local industry and developing low carbon economy. For this reason this research aims to develop a comprehensive framework of support e-government platform, with a specific focus on the e-government system based on Web GIS and private cloud computing based on OpenStack.

Full textAbstract:
The growing quantity and distribution of bioinformatics resources means that finding and utilizing them requires a great deal of expert knowledge, especially as many resources need to be tied together into a workflow to accomplish a useful goal. We want to formally capture at least some of this knowledge within a virtual workbench and middleware framework to assist a wider range of biologists in utilizing these resources. Different activities require different representations of knowledge. Finding or substituting a service within a workflow is often best supported by a classification. Marshalling and configuring services is best accomplished using a formal description. Both representations are highly interdependent and maintaining consistency between the two by hand is difficult. We report on a description logic approach using the web ontology language DAML+OIL that uses property based service descriptions. The ontology is founded on DAML-S to dynamically create service classifications. These classifications are then used to support semantic service matching and discovery in a large grid based middleware project [Formula: see text]. We describe the extensions necessary to DAML-S in order to support bioinformatics service description; the utility of DAML+OIL in creating dynamic classifications based on formal descriptions; and the implementation of a DAML+OIL ontology service to support partial user-driven service matching and composition.

Full textAbstract:
We propose a hierarchical brokering architecture (HiBA) and Mobile Multicloud Networking (MMCN) feedback control framework for mobile device-centric cloud (MDC2) computing. Exploiting the MMCN framework and RESTful web-based interconnection, each tier broker probes resource state of its federation for control and management. Real-time and seamless services were developed. Case studies including intrafederation energy-aware balancing based on fuzzy feedback control and higher tier load balancing are further demonstrated to show how HiBA with MMCN relieves the embedding of algorithms when developing services. Theoretical performance model and real-world experiments both show that an MDC2 based on HiBA features better quality in terms of resource availability and network latency if it federates devices with enough resources distributed in lower tier hierarchy. The proposed HiBA realizes a development platform for MDC2 computing which is a feasible solution to User-Centric Networks (UCNs).

The Internet of Things (IoT) is comprised of connected devices which are equipped with sensors, actuators, and applications to provide services for enabling those objects to connect and exchange data. For these connected devices and the IoT network environment, heterogeneous protocols and frameworks have been published and applied to provide novel IoT services in our daily life. On the Internet, most of the services are provided by existing web service providers which are based on the high-performance processor, storage, and stable power supply. However, devices of the IoT are developed for constrained environments using the small size of equipment to provide seamless services ubiquitously. For accessing the constrained devices and existing web service providers using the clients in the IoT networks such as smart homes, the services of servers from the devices and web service providers shall be discovered by the clients using a consistent discovery service. In this paper, a consistent registration and discovery scheme is proposed for the devices and web service providers in the Open Connectivity Foundation (OCF)-based IoT network. For supporting the proposed scheme, an embedded resource directory (RD) server is proposed to provide a consistent registration service that is used for publishing information of devices and web service providers. For the registration, a unified profile format is used that is based on the RESTful API Modeling Language to describes the information of devices and web service providers. Furthermore, the discovery service provides the consistent interface to discover the registered devices and web service providers by the client using the unified user interface. Accordingly, the client can access the resources of devices and web service providers based on the discovered information.

The goal of distributed heterogeneous information integration is seamless interactions among different business tasks. To achieve the goal, the paper presents a novel middleware framework in service oriented computing (SOC) environment. We analyze the framework in detail and propose three steps for integrating the heterogeneous information resource, including heterogeneous databases. The unified user interface is provided which invoking and binding Web services more dynamically and flexibly in the framework. Especially, we put forward the specific realization process of the core modules of the framework. As an example, we propose the realization of wrapping heterogeneous database as Web services. Finally, we propose the services oriented business integration process and provide the remedial measures for the model of the business process integration. The approach can achieve low cost, flexibility to change and full of system extensibility for distributed heterogeneous information integration.

The effective access and use of geospatial information (GI) resources acquires a critical value of importance in modern knowledge based society.

A mashup is a web page or application that combines data from two or more sources so as to create new services or enhance original services. Mashup technique is usually implemented in web-based applications at web browser via drag-and-drop actions. These web-based applications usually require extra programming efforts when integrating with a non-web application, and they usually cannot drop out the APIs style programming. The developers require indicating specific data source for their new mashup applications, and usually the functions of these applications are limited due to developers’ design in developing time. This kind of programming style is difficult to mashup more data sources coherently, and it is high coupling, resource limited, and difficult to be extended. To solve these issues, this paper proposes a uniform and coherent mashup technique based on the OSGi (Open Service Gateway Initiative) framework. OSGi is a module system and service platform that implements a complete and dynamic component model. By using the OSGi’s dynamic and flexible features, applications could be easily to deploy, remove, discovery, and combine with each other. The key features of proposed mashup technique include the definition of uniform identity terms and invoking chains. The uniform identity term is used to match each application service. Developers can leverage non-web mashup applications by declaring the simple definition of uniform identity term without providing and using any APIs. The invoking chains could link and combine relative application services or data with unlimited length and irregular mixing. After that, the system could build up invoking chains to perform mashup technique automatically. Therefore, developers could mashup certain application functions or data to unknown applications in runtime phase. Finally, we present two different use cases to evaluate the capabilities of the proposed technique.

Full textAbstract:
Enterprise Application Integration (EAI) is a major problem confronting manufacturing organizations that have deployed large-scale enterprise information systems and aim to coordinate inter- and intraorganizational product development, supply-chain, and customer management activities. Successful EAI is a key enabling step toward implementation of viable Product Life-cycle Management (PLM) strategies. Extant EAI technologies, such as distributed object and messaging technologies for communication and ontology-based database schema integration, are tedious to develop and maintain in an organization. Though workflow management systems have enabled process coordination of both manual and system-oriented tasks in organizations, coping with the lack of adaptability and inter-operability in workflow systems is a manual and resource intensive effort. Recent advances in (i) standardized, modular, and distributed software delivery frameworks, such as web services; (ii) standard semantic markup languages for developing domain ontologies; and (iii) intelligent process coordination frameworks promise the development of flexible, responsive, integrated, and organic process management architectures. In this paper, we present an intelligent mediator-based architecture for enabling EAI. Intraorganizational information sources and services are made available via a web-services framework. An Integrated Service Planning and Execution (ISP&E) framework interleaves service composition and execution at the mediator to fulfill service requests. Processes that interleave information gathering and transactional tasks are generated using domain-independent Hierarchical Task Network (HTN) AI planning and a domain-specific ontology and then executed in a scalable and reliable manner. Benefits and limitations of mediator-based frameworks for EAI and topics for further research are discussed based on a prototype development experience.

Cloud computing is a phenomenon that is changing information technology, with many companies no longer having data and resources retained within their own premises. Instead they are utilising cloud computing and its centralised resources. There are many benefits of this approach such as pay-per-use model, elasticity of operation and on demand resourcing. However, this approach also introduces additional security challenges. Security involves a triad of considerations, those being confidentiality, integrity and availability, often abbreviated to CIA. This work focusses on the last aspect of the CIA triad – availability, which is even more crucial for cloud-based platforms as centralised resources need to be provided at a distance to the end customers. Several factors including ‘denial of service’ attack impact availability. Moreover, current protection frameworks do not sufficiently consider the issues of verification, scalability and end-to-end latency. Hence, a new framework has been designed to fill the identified gap. The framework referred to as the cloud-based Distributed Denial of Service Alleviation System (DDoSAS) is based on its predecessor Enhanced DDoS-MS. The new framework has been implemented using Amazon Web Services. The work serves to provide a baseline for measuring end-to-end latency in real-life scenarios.

Portals to computational/data grids provide the scientific community with a friendly environment in order to solve large-scale computational problems. The Grid Resource Broker (GRB) is a grid portal that allows trusted users to create and handle computational/data grids on the fly exploiting a simple and friendly web-based GUI. GRB provides location-transparent secure access to Globus services, automatic discovery of resources matching the user's criteria, selection and scheduling on behalf of the user. Moreover, users are not required to learn Globus and they do not need to write specialized code or to rewrite their existing legacy codes. We describe GRB architecture, its components and current GRB features addressing the main differences between our approach and related work in the area.

Abstract. Sharing and management of geospatial data among different communities and users is a challenge which is suitably addressed by Spatial Data Infrastructure (SDI). SDI helps people in the discovery, editing, processing and visualization of spatial data. The user can download the data from SDI and process it using the local resources. However, large volume and heterogeneity of data make this processing difficult at the client end. This problem can be resolved by orchestrating the Web Processing Service (WPS) with SDI. WPS is a service interface through which geoprocessing can be done over the internet. In this paper, a WPS enabled SDI framework with OGC compliant services is conceptualized and developed. It is based on the three tier client server architecture. OGC services are provided through GeoServer. WPS extension of GeoServer is used to perform geospatial data processing and analysis. The developed framework is utilized to create a public health SDI prototype using Open Source Software (OSS). The integration of WPS with SDI demonstrates how the various data analysis operations of WPS can be performed over the web on distributed data sources provided by SDI.

Two frameworks were applied in our analysis, the ‘framework for analysing integration of targeted health interventions in systems’ and ‘Health in All Policies’ framework for country action. A comprehensive description of the methods is included in our published protocol.Results6117 papers were identified, only 18 studies met the inclusion criteria. Facilitators in implementation included: training for providers, colocation of services, transportation services to enhance access, clear role definitions and appropriate budget allocation and financing. Barriers included: lack of a participatory approach, insufficient resources for providers, absence of financing, unclear roles and insufficient coordination of interprofessional teams; low availability and use of data, and turf wars across governance stakeholders. Successful strategies to address refugee health included: networks of service delivery combining existing public and private services; system navigators; host community engagement to reduce stigma; translation services; legislative support and alternative models of care for women and children.ConclusionLimited evidence was found overall. Further research on intersectoral approaches is needed. Key policy insights gained from barriers and facilitators reported in available studies include: improving coordination between existing programmes; supporting colocation of services; establishing formal system navigator roles that connect relevant programmes; establishing formal translation services to improve access and establishing training and resources for providers.

The semantic web brings a new opportunity for efficient information organization and search. To meet the special requirements of the educational field, this paper proposes an intelligent search engine enabled by educational semantic support service, where three kinds of searches are integrated into Educational Information Intelligent Search (EIIS) framework, and web-based resources and local e-resources are both identically semantically processed. During the design, the EIISReasoning and its relevant rule sets are constructed to automatically reason semantic concepts to diverse levels by a semantic factor and a response time factor. Furthermore, the EIISRanking algorithm applies two-level ranking by a factor of semantic similarity, and the same relevance is differentiated in terms of the educational field’s needs. The experiments show that the EIIS engine with semantic services has a better precision rate and improved ranking performance.

Full textAbstract:
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.

Purpose The distant data centre-centric Internet of Things (IoT) systems face the latency issue especially in the real-time-based applications, such as augmented reality, traffic analytics and ambient assisted living. Recently, Fog computing models have been introduced to overcome the latency issue by using the proximity-based computational resources, such as the computers co-located with the cellular base station, grid router devices or computers in local business. However, the increasing users of Fog computing servers cause bottleneck issues and consequently the latency issue arises again. This paper aims to introduce the utilisation of Mist computing (Mist) model, which exploits the computational and networking resources from the devices at the very edge of the IoT networks. Design/methodology/approach This paper proposes a service-oriented mobile-embedded Platform as a Service (mePaaS) framework that allows the mobile device to provide a flexible platform for proximal users to offload their computational or networking program to mePaaS-based Mist computing node. Findings The prototype has been tested and performance has been evaluated on the real-world devices. The evaluation results have shown the promising nature of mePaaS. Originality/value The proposed framework supports resource-aware autonomous service configuration that can manage the availability of the functions provided by the Mist node based on the dynamically changing hardware resource availability. In addition, the framework also supports task distribution among a group of Mist nodes.

The traditional three-layer Internet of things (IoT) model, which includes physical perception layer, information transferring layer and service application layer, cannot express complexity and diversity in agricultural engineering area completely. It is hard to categorize, organize and manage the agricultural things with these three layers. Based on the above requirements, we propose a new service-oriented grid-based method to set up and build the agricultural IoT. Considering the heterogeneous, limitation, transparency and leveling attributes of agricultural things, we propose an abstract model for all agricultural resources. This model is service-oriented and expressed with Open Grid Services Architecture (OGSA). Information and data of agricultural things were described and encapsulated by using XML in this model. Every agricultural engineering application will provide service by enabling one application node in this service-oriented grid. Description of Web Service Resource Framework (WSRF)-based Agricultural Internet of Things (AIoT) and the encapsulation method were also discussed in this paper for resource management in this model.

Abstract. Work over the last decade has resulted in standardised web services and tools that can significantly improve the efficiency and effectiveness of working with meteorological and ocean model data. While many operational modelling centres have enabled query and access to data via common web services, most small research groups have not. The penetration of this approach into the research community, where IT resources are limited, can be dramatically improved by (1) making it simple for providers to enable web service access to existing output files; (2) using free technologies that are easy to deploy and configure; and (3) providing standardised, service-based tools that work in existing research environments. We present a simple, local brokering approach that lets modellers continue to use their existing files and tools, while serving virtual data sets that can be used with standardised tools. The goal of this paper is to convince modellers that a standardised framework is not only useful but can be implemented with modest effort using free software components. We use NetCDF Markup language for data aggregation and standardisation, the THREDDS Data Server for data delivery, pycsw for data search, NCTOOLBOX (MATLAB®) and Iris (Python) for data access, and Open Geospatial Consortium Web Map Service for data preview. We illustrate the effectiveness of this approach with two use cases involving small research modelling groups at NATO and USGS.

Banking and Financial Services Corporations need to update information systems with logic and data of various applications on everyday basis to remain consistent with change in economy and business activity. This helps to work with latest information included in information system available in current economic and business scenario. This enables information systems and empowers work force to complete tasks in rapidly changing flow of monetary resources. With several employees in Banking and Financial Services Corporations using cloud infrastructure and reporting incidents arising in using cloud infrastructure, it is of prime importance to fix incidents reported within specific timelines. IT change management process is followed in order to adhere to IT governance & compliance framework and reduce risk of failure while performing changes in cloud infrastructure. With incident management and change management processes are aligned to keep cloud infrastructure available and secure, they become integral part of IT operations everyday activity. To make ITIL processes efficient, further organization specific policies are developed. With global standards and organization level controls in place, there are failures in IT incident and change management processes and implementation. In this paper, we have identified the risk arising due to incident management and change management processes that lead to emergency changes being implemented on cloud infrastructure architecture and discussed the steps to mitigate risks to bring greater responsibility and accountability for cloud services providers.

Processing big data on traditional computing infrastructure is a challenge as the volume of data is large and thus high computational complexity. Recently, Apache Hadoop has emerged as a distributed computing infrastructure to deal with big data. Adopting Hadoop to dynamically adjust its computing resources based on real-time workload is itself a demanding task, thus conventionally a pre-configuration with adequate resources to compute the peak data load is set up. However, this may cause a considerable wastage of computing resources when the usage levels are much lower than the preset load. In consideration of this, this paper investigates an auto-scaling framework on cloud environment aiming to minimise the cost of resource use by automatically adjusting the virtual nodes depending on the real-time data load. A cost-effective auto-scaling (CEAS) framework is first proposed for an Amazon Web Services (AWS) Cloud environment. The proposed CEAS framework allows us to scale the computing resources of Hadoop cluster so as to either reduce the computing resource use when the workload is low or scale-up the computing resources to speed up the data processing and analysis within an adequate time. To validate the effectiveness of the proposed framework, a case study with real-time sentiment analysis on the universities’ tweets is provided to analyse the reviews/tweets of the people posted on social media. Such a dynamic scaling method offers a reference to improving the Twitter data analysis in a more cost-effective and flexible way.

In the context of Web services, access control presents some interesting challenges, especially when services are exposed to a global audience, with users accessing them from different systems and under different security settings. A decentralized approach to access control, which can be applied to such open environments, is represented by Trust Management. In fact, it is based on the peer-to-peer delegation of access rights among users, also across organizational boundaries, without supposing a-priori the existence of trusted third parties in the system. This article presents dDelega, a Trust Management framework for SOAP-style and REST-style Web services, available as open source software and usable in different application scenarios. The framework allows users to create multiple levels of delegation of access rights for protected resources. It defines various certificates, for binding names, permissions and oblivious attributes to users, adhering to relevant standards, such as WS-Security, SAML and XACML.

We present the SweGrid Accounting System (SGAS) — a decentralized and standards-based system for Grid resource allocation enforcement that has been developed with an emphasis on a uniform data model and easy integration into existing scheduling and workload management software. The system has been tested at the six high-performance computing centers comprising the SweGrid computational resource, and addresses the need for soft, real-time quota enforcement across the SweGrid clusters. The SGAS framework is based on state-of-the-art Web and Grid services technologies. The openness and ubiquity of Web services combined with the fine-grained resource control and cross-organizational security models of Grid services proved to be a perfect match for the SweGrid needs. Extensibility and customizability of policy implementations for the three different parties that the system serves (the user, the resource manager, and the allocation authority) are key design goals. Another goal is end-to-end security and single sign-on, to allow resources to reserve allocations and charge for resource usage on behalf of the user. We conclude this paper by illustrating the policy customization capabilities of SGAS in a simulated setting, where job streams are shaped using different modes of allocation policy enforcement. Finally, we discuss some of the early experiences from the production system.

Summary The huge and dynamic amount of bioinformatic resources (e.g., data and tools) available nowadays in Internet represents a big challenge for biologists -for what concerns their management and visualization- and for bioinformaticians -for what concerns the possibility of rapidly creating and executing in-silico experiments involving resources and activities spread over the WWW hyperspace. Any framework aiming at integrating such resources as in a physical laboratory has imperatively to tackle -and possibly to handle in a transparent and uniform way- aspects concerning physical distribution, semantic heterogeneity, co-existence of different computational paradigms and, as a consequence, of different invocation interfaces (i.e., OGSA for Grid nodes, SOAP for Web Services, Java RMI for Java objects, etc.). The framework UBioLab has been just designed and developed as a prototype following the above objective. Several architectural features -as those ones of being fully Web-based and of combining domain ontologies, Semantic Web and workflow techniques- give evidence of an effort in such a direction.The integration of a semantic knowledge management system for distributed (bioinformatic) resources, a semantic-driven graphic environment for defining and monitoring ubiquitous workflows and an intelligent agent-based technology for their distributed execution allows UBioLab to be a semantic guide for bioinformaticians and biologists providing (i) a flexible environment for visualizing, organizing and inferring any (semantics and computational) “type” of domain knowledge (e.g., resources and activities, expressed in a declarative form), (ii) a powerful engine for defining and storing semantic-driven ubiquitous in-silico experiments on the domain hyperspace, as well as (iii) a transparent, automatic and distributed environment for correct experiment executions.

As computing technology becomes more pervasive and mobile services are deployed, applications will need flexible access control mechanisms. Unlike traditional approaches based on the identity/role for access control, access decisions for these applications will depend on the combination of the required attributes of users and the contextual information. This paper proposes a semantic-aware context-based access control framework (called SA_CBAC) to be applied in mobile web services environment by combining semantic web technologies with context-based access control mechanism. In order to handle context information in the framework, this paper proposes a context ontology to represent contextual information and employ it in the inference engine.

This article aims to examine the interpersonal meaning of hotel web pages using the Appraisal framework in the view of assessing the frequent occurrence of the appraisal subsystem in the text. The employment of attitudinal, graduation and engagement of text construe the alignment. They explain how the hotel introductory text construction does align the reader. Martin & White (2005) argued that appreciation reaction framework determines interpersonal significancies. The emotive prosody of this appreciation reaction is “it grabs me”, decorative, and then “I want it” (Martin & White, 57:2005). The dominant result of appreciation resources of reaction is shown in this research than other appreciation resources. We can replace the word “it” with the prosody of appreciation. As a result, the appreciation reaction of quality appears dominantly (44%). It means that the hotel talked much about the things: facilities and services. Finally, the interpersonal meaning of the hotel Webpages is ‘I am the most / I am the best’. It implies that the hotel is the best in quality and services in order to attract the reader. It proves that the web pages authentically in constructing the text in order to persuade the potential customer to purchase the hotel product.
