Anything better than ruby alchemy for extracting keywords?

Question

I've currently written an algorithm in Ruby based on the arc90 readability code to extract an article from a web page.

Now that I have the article, I want to extract keywords and specific information from it (names, author, etc)

I heard Alchemy was a great ruby gem for doing this though it consumes a lot of resources. Are there any better gems I can use for this?

Answer 1

There is an OpenCalais gem which provides similar capability. In addition to entity extraction it can also detect events and relations between entities. It's not lightweight, though I couldn't tell if it's better or worse than Alchemy as I haven't used the Alchemy gem. Hope this helps.
