SemTab: Semantic Web Challenge on Tabular Data to Knowledge Graph Matching

This challenge aims at benchmarking systems dealing with the tabular data to KG matching problem, so as to facilitate their comparison on the same basis and the reproducibility of the results.

We have a discussion group where we share the latest news about the challenge.
