Conflations

• See Help:Conflation of two people

Semantic Scholar often sucks

it should be noted. Names are often conflated wildly. Don't trust the robots. -Animalparty (talk) 05:32, 4 December 2020 (UTC)

Indeed: the first example supposedly link to Tim Berners-Lee's Semantic Scholar page, but that id actually corresponds to "Hu-Cao"'s Semantic Scholar page. Natematic (talk) 14:30, 15 January 2021 (UTC)

I wish we could improve the use of this property

So often this property is inaccurate, assembled by the bots purely on vague initials. Recently I’ve seen 7 or 8 identifiers for one person. I think it’s useless due to its inaccuracies. Trilotat (talk) 02:12, 15 July 2021 (UTC)
