Abstract: Services discovery based on syntactic matching cannot adapt to the open and dynamic environment of
the web. To select the proper one from the web services candidate set provided by syntactic matching, a service
selection method based on semantic similarity is proposed. First, this method defines a web services ontology
including GoS and context as semantic supporting, which also provides a set of terms to describe the interfaces
of web services. Secondly, the similarity degree of two web services is evaluated puting the semantic
distances of those terms used to describe interfaces. Compared with existing methods, interfaces of web services
can be interpreted under ontology, because it provides a formal and semantic specification of conceptualization.
Meanwhile, efficiency and accuracy of services selection are improved.
