A QoS-assured Trust-driven Semantic Web Service Discovery Method
Buqing Cao, Jianxun Liu, Bing Li · Journal of Convergence Information Technology · 2011
It have become very difficult that users can find the best, credible web service for some proposed semantic web service discovery methods, because web service environment has become open, autonomic, dynamic, and deceptive. This paper proposes a QoS-assured trust-driven semantic web service discovery method i.e. TDSWSD. This method, firstly, describes and labels web services by ontology technology, and then makes use of the existing keyword matching method to carry basic matching; secondly, function matching will be done by ontology-based concept semantic similarity calculation method; finally, QoS-assured trust measure method will be designed to carry credible QoS matching. Compared with existing methods, the experimental results show that this method can not only automatically find the service to meet user’ requirements, but also ensure the validity and reliability of service discovery.
