Hi Rhys, I'm using the Yahoo term extraction for the BBC Touch website I did http://cgriley.com/bbctouch (it extracts the subjects from the stories) and I also use it in a couple of other places (for instance generating tags for my blog posts). I've also seen the offering from TryNT and given it a test run.
>From what I've seen TryNT's returns a lot of terms for a given bit of text, and from memory I recall the terms weren't always as accurate as Yahoo's. For my particular applications I've always wanted a fairly low number of terms so I've counted that as a weakness, but maybe not for your application. Something I've also done is to use both services to extract a list of terms, and then use only the terms found in both lists, but this proved unsuccessful in the real world as not enough terms matched. I'd be interested in seeing the results of a study of them side by side, and for any others you find. However I think for use in an application your best bet is to try them both out on real data and see which works best, then go with that one, or a combination if needed. Finally you benefit from the Yahoo one being more popular as you have more code samples to look at!
