Ontology-based Web Services Reliability Model
基于本体的Web服务可靠性模型

Reliability plays an important role in the selection and combination of Web services. With the popularization of Web services, researches on minimizing the discovery duration and improving precision ration are getting more important. This paper proposed a new ontology-based approach, called OntoRel, to evaluate Web services reliability. The OntoRel approach analyzes the measurement criteria and relation of reliability attributes, builds the ontology model and measures the reliability of Web services. The approach is characterized by the management and development of rehabihty knowledge domain,the evaluation and prediction of Web services reliability and the automatic selection and combination of Wcb services.
