Subject RowSimilarityJob

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 

For SIMILARITY_COSINE is the value = cosine or 1 - cosine?

Is the value calculated after cooccurrences determines similar docs 

The code is very difficult to read so a little help would be appreciated.
