[jira] Created: (MAHOUT-570) Make the retrieval of candidate items for the most-similar-items computation customizable

Make the retrieval of candidate items for the most-similar-items computation customizable
-----------------------------------------------------------------------------------------

                 Key: MAHOUT-570
                 URL: https://issues.apache.org/jira/browse/MAHOUT-570
             Project: Mahout
          Issue Type: Improvement
          Components: Collaborative Filtering
    Affects Versions: 0.5
            Reporter: Sebastian Schelter


When retrieving the initial set of possibly similar items in GenericItemBasedRecommender.doMostSimilarItems(...) only co-occurring items are selected. We need an exchangable strategy (similar to the existing CandidateItemsStrategy) in order to make this behavior customizable.
