Ankur commented on MAHOUT-103:
------------------------------
Alright! then I'll incorporate 1 and 2 as suggested by Sean and also add some
documentation. To digress a little bit, I would also like to suggest a map-red
implementation of the log-likelihood ratio test as described in Ted's paper. As
in my own experience simple co-occurence counts don't take into account the
popularity bias that gets introduced because of items that have unusually high
number of occurrences.

> Nearest neighborhood type queries for users/items can be answered efficiently
> and effectively by analyzing the co-occurrence model of a user/item w.r.t
> another. This patch aims at providing an implementation for answering such
> queries based upon simple co-occurrence counts.
