Abstract
This paper presents a schema matching method for the transformation of XML documents. The proposed method consists of two steps: computing preliminary matching relationships between leaf nodes in the two XML schemas based on proposed ontology and leaf node similarity, and extracting final matchings based on a proposed path similarity. Particularly, for a sophisticated schema matching, the proposed ontology is incrementally updated by users' feedback. Furthermore, since the ontology can describe various relationships between concepts, the proposed method can compute complex matchings as well as simple matchings. Experimental results with schemas used in various domains show that the proposed method performs better than previous methodologies, resulting in a precision of 97% and a recall of 83% on the average.
