With the proliferation of Web technologies, theneed to deliver services via the Web has increasedtremendously. More and more, customers now demandone-stop service that calls for multiple servicescrossing organizational boundaries, which arerequired to be carefully and dynamically composed ina customized manner. Such a composition should notonly select the most appropriate available service, butshould also adhere to the policies and regulationsgoverning the organizational services. In this paper,we demonstrate how such a composition can beaccomplished to form a coherent service flow by usingrules and services expressed as a knowledge base andtopic ontology. The description of rules with topicconcepts allows the system to easily identify therelevant rules in a certain domain and to identify andselect appropriate Web services for composition. Weconsider different types of compositional rulesincluding syntactic, semantic and pragmatic(contextual), which play a major role in the discoveryand selection of Web services. We model theknowledge of rules and of the topic ontology usingOWL, DAML-S, RuleML and RDF standards.
