Hello, I played around a little bit with recommendations for anonymous users. Therefore I have simply build a preference array based on the recently visited items, like it is explained in "Mahout in Action". This seems to work out pretty well since the recent items perfectly relate the user's latest interests. However, now I want to include the most recent visited items into my main recommender, i.e. the recommender based on the historical data of known users. Any ideas on how to add temporary user preferences to the data model? As far as I understood the PlusAnonymousDataModel, this is no solution since it only supports one user and is not thread safe. Thanks in advance!
Best, Matthias
