Hi, I was playing with the examples and the demo, and to my best understanding, the recommendation is based on either "user-based" or "item-based". For example, the groupLens demo only looks on ratings but not on users data (i.e. demographics). I have 2 files, one for users and one for their ratings. Is there a way to combine them both and get better recommendation ? I'll appreciate if you can point me to such an example. thanks, Michal
