Abstract
Bringing semantics to Web Services description and matching remarkably improves the recall and precision ratios of Service discovery. Though there are many effective semantic based Web Services matchmakers, they have poor time efficiency for consuming time in the semantic reasoning step. To shorten service matching time, this paper presents a fast matchmaker for OWL-S services, called XServices Semantic Service Discovery (XSSD). It executes the Semantics Pretreatment Algorithm (SPA) in service publishing phase and implements a multi-feature based Semantic Web services matching method when queries coming. SPA extracts part of semantic description in the OWL-S files and creates matrixes which we call service feature matrixes to express service semantics. By shifting part of the reasoning process from service matching stage to service publishing stage, XSSD reduces the waiting time for the matchmaker clients. The results of the evaluation on a well-annotated Semantic Web Services set OWLS-TC4 show that while XSSD offers the comparable recall and precision ratios, the time efficiency of XSSD outperforms existing similar matchmakers.
