Matching Web Services Based on Semantic Similarity

Classical matching on web services provides only coarse granularity methods, which classify the matching into several levels. Such level restricted methods prohibit the evaluation of matching within the same level which is necessary for modern web service compositions. This paper offers a finegrained matching method based on the semantic similarity of the services. By the semantic distances and the depth of concepts of ontology, a novel precise matching method is proposed to match the web services between levels and within the same level. Experiments show that the approach leads to better precision and recall.
