[...]... monitoring, and composition of Web services In this book, we describe an end-to-end framework for semantic Web service composition 1.2 Web Service Composition Web service composition refers to the process of combining several Web services to provide a value-added service [35, 208] It is emerging as the technology of choice for building cross-organizational applications on the 1.3 Semantic Web Support for Automatic... we propose semantic Web approach for supporting the automatic composition of Web services Composers would specify the what part of the desired composition (i.e., the tasks to be performed), but will not concern themselves with the how part (e.g., which services will be outsourced) They would provide “abstract” definitions of the actions they would like to perform The process of composing Web services... on Web services reduces business risks since reusing existing services avoids the introduction of new errors Third, composing Web services enables the reduction of skills and effort requirements for developing applications Finally, the possibility of outsourcing the “best-in-their-class” services allows companies to increase their revenue 1.3 Semantic Web Support for Automatic Service Composition Web. .. interactions in the Semantic Web These include ontologies, Web services, semantic Web services, software agents, and XML-based standards In Section 2.5, we describe current commercial platforms for supporting interactions on the Web In Section 2.6, we overview Web service composition research prototypes Finally, Section 2.7 provides a tabular comparison summary of the existing solutions for Semantic Web interactions... generated for a given composition request The composition engine should, in this case, be able to assess the “quality” of the generated composite services 1.6 Preview of Chapters 11 1.6 Preview of Chapters In this book, we present an end-to-end framework for the automatic composition of Web services on the envisioned Semantic Web We illustrate the major research thrusts to be addressed for a semantic Web. .. as an extension of the existing Web, in which information is given a well-defined meaning [19] The ultimate goal of the envisioned Semantic Web is to transform the Web into a medium through which data and applications can be automatically understood and processed 1.1 Semantic Web Services The development of concepts and technologies for supporting the envisioned Semantic Web has been the priority of various...

AreaAgencyAging 2.2 A Taxonomy for Semantic Web Interactions In the first part of this section, we identify the different layers that make up an interaction framework on the Semantic Web We then define the dimensions for assessing interactions across these layers These dimensions are used as a benchmark for evaluating Semantic Web interaction solutions 2 Enabling Interactions on the Web: A Taxonomic Perspective... Automatic Composition of Web Services require access to the applicant record with a taxation office Note that Web services may also be linked by post-execution relationships The composition engine should be able to automatically include pre- and post-execution relationships in the generated composite service As illustrated in the aforementioned example, the automatic composition of Semantic Web services . class="bi x0 y0 w0 h0" alt="" Service Composition for the Semantic Web Brahim Medjahed • Athman Bouguettaya Service Composition for the Semantic Web Foreword by Schahram Dustdar . as the automatic selec- tion, monitoring, and composition of Web services. In this book, we describe an end-to-end framework for semantic Web service composition. 1.2 Web Service Composition Web. non-functional service properties) on the one side and technology on the other side. So far, there is no standard and agreed-upon way to perform service composition of the Semantic Web. In this book the
