It seems like these functions can be used to compute precision and
recall for something like a search engine, where you get a set of
results for a query, but not for classifier evaluation.
Interesting, is this true? I see a post by Jacob Perkins on StreamHacker (his blog) saying something different. It would be great if there's an official confirmation on this.
