An Ontology-Based Process Description and Reasoning Approach for Service Discovery

In web service research field, discovering proper services to satisfy requirements is a key issue for service reuse. A main obstacle is the different levels of abstraction between requirements and service description. In this paper, we propose an ontology-based method to organize processes according to their functions, and reasoning rules are defined basing on the ontology. In this method, a service can be determined whether it can satisfy a process by the vector space model and cosine similarity of function descriptions, and reasoning rules are employed to discover services which have no relationships with the process literally. This method provides more efficient services discovery for the implementation of process.
