bbw: Matching CSV to Wikidata via Meta-lookup
Renat Shigapov, Philipp Zumstein, Jan Kamlah, Lars Oberländer, Jörg Mechnich, Irene Schumm
We present our publicly available semantic annotator bbw (boosted by wiki) tested at the second Semantic Web Challenge on Tabular Data to Knowledge Graph Matching (SemTab2020). It annotates a raw CSV-table using the entities, types and properties in Wikidata. Our key ideas are meta-lookup over the SearX metasearch API and contextual matching with at least two features. Avoiding the use of dump files, we kept the storage requirements low, used only up-to-date values in Wikidata and ranked third in the challenge.
