Abstract: Matchmaking plays an important role in Web services interactions.
The matchmaking based on keywords easily leads to low precision, Meanwhile, the
current semantic service discovery methods perform service I/O based profile
matching, there exists no matchmaker that performs an integrated service
matching by additional reasoning on logically defined preconditions, effects,
Qos and so on. In this paper, the semantic web services are described based on
Description Logics, and the services description model is designed, which
describes the various aspects (such as IOPEs, Qos and so on) of the web
services. So the services matchmaking is transformed into the match of
concepts. The service match algorithm is proposed and the description logics
reasoner RacerPro is adopted for Web services discovery. We show how the
semantic matching between providers and a requester is performed by a case
study.
