What is the value created to describe simlarity by RowSimilarityJob? The
paper which describes how the algorithm is implemented doesn't describe
the various similarity values returned by mahout. It seems to focus on
cooccurrences.
For SIMILARITY_COSINE is the value = cosine or 1 - cosine?
Is the value calculated after cooccurrences determines similar docs
independently?
The code is very difficult to read so a little help would be appreciated.
