Service Similarity Measure Based on Semantic Distance of Ontology Concepts
Qiu Yu-hui · 2009
With the application of semantic Web service and semantic Grid service,the requests of service resource are on the fly,and service matching is more and more important in the domain of service discovery and service composition.Under the precondition of service described by OWL-S,service matching are generally considered as the matching of ontology concepts,and the purpose of concepts matching is that finding semantic similarity between concepts.The semantic similarity between concepts is influenced not only by the distance between concepts,but also by position of concept in the ontology hierarchy architecture.In this paper,considering the above two factors,we proposed a concepts similarity measure based on the semantic distance,defined the semantic distance,and stated the relationship between the semantic distance and semantic similarity.At last,we also provided an experimental comparison of our measure against traditional similarity measures,and proved empirically the benefits of our approach.
