I think that it depends on just what data is used from them. I've looked a bit at the Yago data. The mappings from Wikipedia categories to WordNet synsets are pretty good, although there will be some errors. The instance relationships are less good as they are just the Wikipedia category membership relationships, which are known to have problems.
So I would think that what to get from Yago is the Wikipedia to Wordnet mappings, not the instance relationships. I haven't looked at BabelNet much. My expectation is that they will have more mappings but maybe at the price of more errors. If there is a desire to have a mapping from Wikidata to Wordnet, the only reason to not want to use of these efforts as a start is the quality of their mapping. Perhaps one option is to repeat something along the lines of what they did but more closely tailored to the situation in Wikidata. peter On 08/21/2017 07:56 AM, Denny Vrandečić wrote: > I think we could ask either Yago or BabelNet or both whether they would be > receptive to release their mappings under a CC0 license, so it can be > integrated into Wikidata.
