Service Task

Recently, Semantic Annotations for WSDL (SAWSDL) standard emerged as a W3C recommendation to add semantics to WSDL components. SAWSDL annotates WSDL components with different semantics in order to automate Web service tasks, such as service discovery, composition, mediation, and invocation. In fact, certain service task requires a specific service semantic that semantically describes the service. As a result, several tools and techniques have emerged to allow users to get maximum advantage of semantic Web service by implementing SAWSDL. This paper analyzes SAWSDL standard. The relationships between SAWSDL and WSDL components were revealed. The direct relationships between SAWSDL components and service tasks through service semantics were investigated and reported. This paper also reviews some well-known tools that are used for SAWSDL implementation.

Service Matching

At present, as the number of web services resources on the network drastically increased, how to quickly and efficiently find the needed services from publishing services has become a problem to resolve. Aiming at the problems of low efficiency in service discovery of traditional web service, the formal concept analysis ( FCA) is introduced into the semantic Web service matching, and a Matching Algorithm based semantic web service is proposed. With considering the concept of limited inheritance,this method introduces the concept of limited inheritance to the semantic similarity calculation based on the concept lattice. It is significant in enhancing the service function matching in practical applications through adjust the calculation.

Semantic Discovery

This chapter surveys existing approaches to Semantic Web service discovery. Such semantic discovery will probably substitute existing keyword-based solutions in the near future, in order to overcome the limitations of the latter. First, the architectural components along with potential deployment scenarios are discussed. Subsequently, a wide range of algorithms and tools that have been proposed for the realization of Semantic Web service discovery are presented. Moreover, key challenges and open issues, not addressed by current systems, are identified. The purpose of this chapter is to update the reader on the current progress in this area of the distributed systems domain and to provide the required background knowledge and stimuli for further research and experimentation in semantics-based service discovery.
