Ask HN: Keyword extraction library recommendations?

Hi - I need to do keyword extraction from substantial amounts of text (100s of dcouments, perhaps scaling to 1000s), and I know people have done this before so I'm keen to avoid re-inventing the wheel. Any recommendations?

  That has loads of useful tools - thanks - although a 20 minute browse doesn't seem to have exactly what I want. It's plausible that I can build what I want from what they have, but it's not clear. But it's a good start - thanks.
