It's official since a couple of minutes, there will be a 2nd Challenge on Context-aware Movie Recommendation at RecSys2011.
Needless to say we're excited. The focus this year will be a bit different from last year's CAMRa, we're aiming at a social context this year which will include household information. We're working on a website which should be available soon at CAMRa2011.
This year we're teaming up with Moviepilot again and will be releasing another batch of interesting datasets.
