1. why not use the other columns as evidences and come up with a preference
score  <UID> <ITEMID> <PREF_SCORE> and see if results improve.. May be you
use  other machine learning algorithms to generate such preference
scores...


2. one other way may be to implement a custom similarity Score and not the
ones that ships with mahout  where you can use this column values to decide
on the similarity of the users. Kindly have a look at mahout in action.
There is an example for dating recommendation. This problem of yours
<USERID,ITEMID> can mapped back to the same problem mentioned. try
implementing the similarity score using the other column values.


May be some  expert in this area  can come up with a better solution...if i
were you i would certainly test the waters like the way i mentioned...
