A Heuristic Approach for Automated Composition of Semantic Web Services

摘要

Web services composition is a combinatorial problem.Automated composition of Semantic Web Services can be achieved by using heuristic approach.Semantic can formal present the property of web service,there for,Semantic Web Services can be considered as a subset of knowledge domain.Considering a granular knowledge domain consisting of a large number of individual properties and a large number of services that provide mappings between sets of properties,the objective of the services composition is to select a minimum cost combination of service that can provide a joint mapping from a given set of input properties to a set of output properties.A general framework for heuristic is presented.
