Someone recently posted a 30 line scala implementation of a tf-idf variant on hackernews, the github link is here. I thought I'd just check if it were possible to code the same variant more succinctly in clojure, but it wasn't really possible (although I include whitespace and have several functions). Thought I'd post it here just for fun.

If you're interested in clojure, we're hiring at ReadyForZero.

Discuss this on hacker news.
