Ask HN: Trying to remember name of startup that did named entity recognition

So I'm trying to remember the name of this startup/web service (that I believe was acquired by Google in like 2010) that let you add a bunch of things you liked, and it knew how to disambiguate them.

There was a search bar, and if you searched for something like Warpaint, it would show: Warpaint (band) - kinda like Wikipedia does, but at a much finer-grained level.

Does anyone remember what this was? Or does anyone know if there's an API that offers a similar service?

I love getting recommendations - be it for movies, albums, songs, podcasts etc, I've been wanting to make an app for myself that lets me add these cool things I'm being recommended. Sure I could use a note-taking app, but it would be nice if it could detect "Disco//very" as a song by the band Warpaint, which can then let me pretti-fy and link to Spotify and so on.
