-----------------------------------
Key: MAHOUT-1428
URL: https://issues.apache.org/jira/browse/MAHOUT-1428
Project: Mahout
Issue Type: Bug
Components: Collaborative Filtering
Affects Versions: 1.0
Reporter: Mario Levitin
Labels: easyfix
Fix For: 1.0
Mahout does not recommend items which are already consumed by the user.
For example,
In the getAllOtherItems method of GenericUserBasedRecommender class
there is the following line
possibleItemIDs.removeAll(dataModel.getItemIDsFromUser(theUserID));
which removes user's items from the possibleItemIDs to prevent these
items from being recommended to the user. This is ok for many
recommendation cases but for many other cases it is not.
The Recommender classes (I mean all of them, NN-based and SVD-based as
well as hadoop and non-hadoop versions) might have a parameter for this for
excluding or not excluding user items in the returned recommendations.
