Asymmetric Web Service Operation Matching in Structural-Level Similarity Measure

Abstract

A structural-level Web service operation matching method with asymmetric characteristic is proposed in this paper. Our work focuses on the data-type matching based on XML schema, and the problem is a labeled tree edit distance calculation. We introduce the asymmetric characteristic of matching into the tree edit distance model and it can effectively improve the top-k precision of the fetching result set of operations.
