Release

[tvo]

Hey,

Any chance you could push out a new release that includes the performance optimizations?

TIA

See https://github.com/opennorth/tf-idf-similarity for a gem with a number of improvements, both in performance and in tf*idf implementation. reddavis' gem normalizes the frequency of a term in a document to the number of terms in that document (which, as far as I can tell, never occurs in the academic literature) and has no normalization component. My gem uses the same formula as Lucene and other major implementations.

Came here to make the same request. Thanks for the link to your project, jpmckinney.
