Central technology of Web service discovery based on semantics
Peng Wen-tao · Journal of Computer Applications · 2006
Because Web Ontology Language Service (OWLS) was lack of clear depiction to Quality of Service (QoS), QoSOn was introduced to extend OWL-S. Then, a matching model named Two Phases was proposed. In this model, the irrelevance services were eliminated by matchmaking based on classification, and similarity functions were introduced to rank semantic similarity between the candidate services and request service. Both OWL-S profile functional similarity and QoS similarity based on QoSOn were evaluated to measure the similarity between the candidate services and the request. The matching algorithm is proved to be feasible and effective by comparative experiments.
