Abstract:

The current infrastructure of Web services discovery such as UDDI provides text-and taxonomy-based search capabilities. With the rapid growth of the number of Web services, the current Web service discovery mechanism becomes inefficient. The service discovery algorithm uses OWLS ontology, and explicitly returns the sequence of atomic process invocations that the client must perform in order to achieve the desired result. When no full match is possibl e, the algorithm features a flexible matching by returning partial matches and by suggesting additional inputs that will lead to a full match.

Key words:  （OWL-S, web service, service discovery, process model）
