Benchmark Datasets for Schema and Ontology Matching

Benchmark Datasets for Schema and Ontology Matching


The table below comprises a set of selected match tasks that have been solved with COMA++. Each match task consists of at least two source schemas (owl or xdr) to be matched against each other. We also provide the presumably perfect mapping result that can be used for evaluating the results of automatic match approaches. If more than two schemas were matched, the mapping file contains the mappings for all possible schema combinations.

Please refer to the papers to see how we determined the perfect mapping.
