Abstract:

In service-oriented architectures, the implementation of distributed computing lies on the solution to the problem of service interaction. It is imper ative that service interfaces be described in a machine understandable way, which can provide a semantic foundation for the dynamic discovery and compos   ition of services. The technique of service semantics annotation satisfies this requirement, which refers to annotating service description by using mac hine understandable metadata from the shared domain ontologies. In this paper, an effective approach to automatic semantics annotation of services is presented. The process of service annotation is divided into two phases： ontology annotation phase, and concept annotation phase. We concentrate on the s solution to the problem of ontology annotation, and present a corresponding algorithm based on machine learning. The experiments on the service resource s in the real world show that this algorithm is highly practical.
