Results of the Instance Matching

For the first time in the OAEI an instance matching track was proposed to participants. The aim of this track is to evaluate matchers on instance data coming from diverse sources. Both data extracted from published the Web datasets, and a testbed presenting various automatically generated values and structure modifications were proposed.

Instance Matching contest was composed by two tracks: IIMB and AKT-Rexa-DBLP. The ISLab Instance Matching Benchmark (IIMB) is a benchmark automatically generated starting from one data source that is automatically modified according to various criteria. The AKT-Rexa-DBLP test case aims at testing the capability of the tools to match individuals. All three datasets were structured using the same schema. The challenges for the matchers included ambiguous labels (person names and paper titles) and noisy data (some sources contained incorrect information).
