Semantic Web Services Matching Algorithm Based on QoS-feedback
Shunli Zhang · Jisuanji gongcheng · 2012
The traditional Web services framework does not support Quality of Service(QoS)-based queries,and can not meet the performance requirements of service users.Based on ontology,this paper establishes the QoS ontology,proposes a two-stage service matching algorithm that based on function and QoS,and an algorithm of QoS-feedback which integrally computes the release and feedback QoS of the service.Experimental results show that the new approach can enhance the precision rate,and improve the performance of service discovery.
