This paper presents the basic design of a new web service search technique for mobile mashup. Web service search means searching web APIs to build a new mobile mashup service. The technique is based on user-oriented profiling and can be easily used on mobile devices. For web service search, a user must know the details of a web service in advance. However, conventional service search cannot provide such information on whether the web service can be used for the mashup. This study discusses a user-oriented web service search technique for mobile mashup. Its key feature is that users can easily search for web services that use mashup on mobile phones without knowing the details.

Mobile devices enabled with Web services are being considered as equal participants of the Web services environment. The frequent mobility of devices and the intermittent disconnection of wireless network require migrating or replicating Web services onto adjacent devices appropriately. This article proposes an efficient method for migrating and replicating Web services among mobile devices through code splitting. Specifically, the proposed method splits the source code of a Web service into subcodes based on users’ preferences for its constituent operations. The subcode with a higher preference is migrated earlier than others. The proposed method also replicates a Web service to other devices to enhance its performance by considering context information such as network traffic or the parameter size of its operations. To evaluate the performance of the proposed method, the effect of the code splitting on migration was analyzed. Furthermore, to show the feasibility of the proposed migration method, three application scenarios were devised and implemented.

The rapid growth of the mobile devices market and the increasing requirements of mobile users augment the need to develop Web Service clients that could be deployed and run on both mobile and desktop devices. Different developers attempt to address this heterogeneity requirement and provide solutions that simplify and automate the development of device-aware services. This chapter proposes a Model-Driven Web Service oriented approach, which allows designing and automatically generating mobile and desktop-based clients that are able to invoke ubiquitously Web Services from different devices. This is further enabled via the Web Services Description Language that allows generating the required proxy classes, which support the communication with platform-specific clients. The applicability and efficiency of the approach is demonstrated via the design and development of a device-aware Web Service prototype.

Recently, web services have presented a new and evolving model for constructing the distributed system. The meteoric growth of the Web over the last few years proves the efficacy of using simple protocols over the Internet as the basis for a large number of web services and applications. Web service is a modern technology of web, which can be defined as software applications with a programmatic interface based on Internet protocol. Web services became common in the applications of the web by the help of Universal, Description, Discovery and Integration; Web Service Description Language and Simple Object Access Protocol. The architecture of web services refers to a collection of conceptual components in which common sets of standard can be defined among interoperating components. Nevertheless, the existing Web service's architecture is not impervious to some challenges, such as security problems, and the quality of services. Against this backdrop, the present study will provide an overview of these issues. Therefore, it aims to propose web services architecture model to support distributed system in terms of application and issues.

Purpose Web services play vital role in the development of emerging technologies such as Cloud computing and Internet of Things. Although, there is a close relationship among the discovery, selection and composition tasks of Web services, research community has treated these challenges at individual level rather to focus on them collectively for developing efficient solution, which is the purpose of this work. This paper aims to propose an approach to integrate the service discovery, selection and composition of Semantic Web services on runtime basis. Design/methodology/approach The proposed approach defined as a quality of service (QoS)-aware approach is based on QoS model to perform discovery, selection and composition tasks at runtime to enhance the user satisfaction and quality guarantee by incorporating non-functional parameters such as response time and throughput with the Web services and user request. In this paper, the proposed approach is based on ontology for semantic description of Web services, which provides interoperability and automation in the Web services tasks. Findings This work proposed an integrated framework of Web service discovery, selection and composition which supports end user to search, select and compose the Web services at runtime using semantic description and non-functional requirements. The proposed approach is evaluated by various data sets from the Web Service Challenge 2009 (WSC-2009) to show the efficiency of this work. A use case scenario of Healthcare Information System is implemented using proposed work to demonstrate the usability and requirement the proposed approach. Originality/value The main contribution of this paper is to develop an integrated approach of Semantic Web services discovery, selection and composition by using the non-functional requirements.

In the last decade, selecting suitable web services based on users’ requirements has become one of the major subjects in the web service domain. Any research works have been done - either based on functional requirements, or focusing more on Quality of Service (QoS) - based selection. We believe that searching is not the only way to implement the selection. Selection could also be done by browsing, or by a combination of searching and browsing. In this thesis, we propose a browsing method based on the Scatter/Gather model, which helps users gain a better understanding of the QoS value distribution of the web services and locate their desired services. Because the Scatter/Gather model uses cluster analysis techniques and web service QoS data is best represented as a vector of intervals, or more generically a vector of symbolic data, we apply for symbolic clustering algorithm and implement different variations of the Scatter/Gather model. Through our experiments on both synthetic and real datasets, we identify the most efficient ( based on the processing time) and effective implementations.

Business collaboration is increasingly conducted over the Internet. Trading parties require business-level protocols for enabling their collaborative processes and a number of standardised languages, and approaches have been proposed for specifying business-level protocols. To illustrate the specification of web services based collaborative processes, three inter-related specification languages, namely, the ebXML Business Process Specification Schema (BPSS), the Web Service Business Process Execution Language (WSBPEL), and the Web Services Conversations Language (WSCL) are discussed in this chapter. A contract negotiation protocol is used as an example to illustrate the concepts involved in the specification. The chapter also discusses different strategies for deploying these specification languages.

More and more systems provide data through web service interfaces and these data have to be integrated with the legacy relational databases of the enterprise. The integration is usually done with enterprise information integration systems which provide a uniform query language to all information sources, therefore the XML data sources of Web services having a procedural access interface have to be matched with relational data sources having a database interface. In this chapter the authors provide a solution to this problem by describing the Web service wrapper component of the SINTAGMA Enterprise Information Integration system. They demonstrate Web services as XML data sources in enterprise information integration by showing how the web service wrapper component integrates XML data of Web services in the application domain of digital libraries.

At the present time and with the economic orientation towards maturity, enterprises unlike the traditional competitive business strategies are wanted out of necessity to cooperate with other enterprises and to add new activities to their existing profiles. The rapid growth of technologies motivates enterprises to invest more and more in this domain with the adoption of the cooperative e-business applications. Consequently, we propose in this paper an approach that permits enterprises to enhance their cooperative activities. This approach is based on the agent and Web services paradigms. It is organized in the form of cooperative application groups representing the different parts of a company. Agent coordinators orchestrate the cooperative work of these groups. The most requested functionalities inside the enterprise and those offered to the external world can be exported as Web Services. We describe the Web Services with DAML-based Web Service ontology (OWL-S). The search, invocation and exploration of these Web services can be offered by an intermediate agent called Web Service Finder Agent. The proposed approach provides a new vision of the cooperation context where the companies and their partners share knowledge and offer functionalities as agents and Web Services.
