An Approach to Semantic Matching of Web Services

One of the challenging problems that Web service technology faces is the ability to effectively discover services based on their capabilities. An approach is proposed to tackle this problem in the context of description logics. The semantic information of a Web service can be described with three factors: functional capabilities, action and non-functional attributes. We formalize these three factors matchmaking and propose a novel matchmaking algorithm that takes as input a service request Q and an ontology T of services and finds a set of services whose functional capabilities, action and non-functional attributes matching ranks are all highest. We then present a simple example to illustrate our approach to semantic matching of Web service.
