Similartity Network For Semantic Web Services Substitution
Web services substitution is one of the most challenging tasks for automating
the composition process of multiple Web services. It aims to improve
performances and to deal efficiently with Web services failures. Many existing
solutions have approached the problem through classification of substitutable
Web services. To go a step further, we propose in this paper a network based
approach where nodes are Web services operations and links join similar
operations. Four similarity measures based on the comparison of input and
output parameters values of Web services operations are presented. A
comparative evaluation of the topological structure of the corresponding
networks is performed on a benchmark of semantically annotated Web services.
Results show that this approach allows a more detailed analysis of
substitutable Web services
