Preliminary Evaluation of Schema Matching Systems
Mikalai Yatskevich · Unitn Eprints Research (Università Degli Studi di Trento) · 2003
This evaluation of the state-of-the-art schema matching approaches is based on a comprehensive testing of modern systems on various real-world schemas. The results obtained show that there is no matcher that performs best on all types of schemas used. The quality of mappings depends significantly on the approaches to schema matching used and on the tuning of the matcher to the particular schema type. The approach proposed in COMA that combines results of different schema matchers proved its effectiveness in our evaluation.
