Abstract: According to the reality that the need of users is becoming more and more diversified in telecommunication service field, the model of semantic Web services in Internet is tailored and a semantic Web services based intelligent telecommunication service model is proposed. In this model, the telecommunication service domain ontology base is designed to achieve knowledge sharing throughout telecommunication service field; the ontology based user personality database is put forward to sharpen the mining of user interests, taking advantage of natural reasoning feature of ontology; Intelligent agent is presented to liberate user from choosing the right service from huge amount of services. A module generating XSLT, the semantic transformation code, is constructed to increase the efficiency of describing semantic Web services. The model is verified in practical testing environment, and a multimedia service is presented to illustrate the working principle of the model in the end.
