摘要：This paper presents a semi-automatic approach to deriving sub-schema similarities from semantically het- erogeneous XML Schemas. The proposed approach is specific for XML, almost automatic and light. It consists of two phases: the first phase selects the most promising pairs of sub-schemas, the second one examines them and returns only those which are similar. This paper describes the approach in all details and illustrates a large variety of experiments to test its performance. Furthermore, it presents a comparison between this approach and others which have already been proposed in the literature.
