COMA - A system for flexible combination of schema matching approaches

Summary: COMA provides a flexible platform to combine multiple schema-matching techniques. It offers a broad suite of matchers, including reuse-based results, and fusion mechanisms; real-schema experiments indicate that combined, reuse-aware strategies outperform single-matchers.
