Yes you must pass a user ID there. I would amend your comment slightly. To really recommend users to items (like 'which user will like this item most?') you would flip your data around. Make users into items and vice versa.
Using the mostSimilarItems convenience method does something similar indeed even if I would say it is not quite the same as recommendation.

That is not possible even if you fix your database. If you want to recommend items for an item, you should use an item based recommender, and its mostSimilarItems function On Mon, Oct 12, 2009 at 11:28 PM, Larry Homes <[email protected]> wrote: > Hello, > > I am tryi... -- Gökhan Çapan
