Service system modeling research based on ontology in the ubiquitous computing environment

With the development of information technology, intelligent electronic services are playing a more and more important role in modern society, especially in the ubiquitous computing environment, in which the characteristics of mobility, openess and context awareness make e-services more complicated and difficult to be managed. Potential conflicts may occur anywhere at any time. This paper analyzes the ubiquitous service system and presents ontology models for each key factor using OWL and modified OWL-S. Finally we integrate these models together. The model presents enough semantic information to recognize potential conflicts of services and also provides strong support for other service management activities.
