Semantic Web Services Discovery and Composition: Paths Along Workflows

Web services are new paradigm of using the Web. One of emerging challenges is to discover Web services efficiently and precisely. Unfortunately, existing systems like UDDI often have the problems of low availability, low accuracy, and bad…

Since the beginning of the service oriented paradigm, the Web service discovery presents an important problem. Web Services should act autonomously with as minimal human intervention as possible, they should be able to discover other services which…

Web services paradigm is considered as the most prevailing instantiation of the service-oriented computing. This computing technology can he used potentially to compose new distributed collaborative applications and make easy the development of more…

Semantic Web services evolved from traditional computational services by semantic descriptions. Recently, there have been many research efforts in the field of semantic Web services, which reveals enormous potential for Service-Oriented Architecture…

The automatic discovery and composition of Web services rely on the facilities offered by the providers of services in describing the functionalities of their services semantically and on the description of the client's requests and their needs,…

Recently, the volume of Web information and the number of user accesses have increased rapidly. Static information can be retrieved by search engines whereas dynamic information may need special programs called Web services. Since each web service…

Matching algorithms for semantic Web services discovery focus on the functional aspects of the services, which are usually given by the function that transforms inputs into outputs. Current approaches do not take into attention the fact that some…

This paper describes a framework for ontology-based flexible discovery of Semantic Web services. The proposed approach relies on user-supplied, context-specific mappings from an user ontology to relevant domain ontologies used to specify Web…

In this paper the matching model for semantic Web services is proposed to improve the performance of Web service discovery. This matching model includes two-phase method: semantic similarity matching and qualitative filtering. Semantic similarity…

As Web resources and information are becoming numerous, many researchers have studied automated processing of the resources and information. In addition, semantic Web services make the Web services represented to be machine-interpretable through the…
