I still get no results when GenericItemBasedRecommender.mostSimilarItems(),and my ItemSimilarity works well. Does GenericItemBasedRecommender.mostSimilarItems() works without preference data? Tim said: "As Sebastian pointed out, you could start out by making recommendations strictly on content-based similarities (such as the output from a More Like This query in Lucene) and then introduce recommendations based on collaborative filtering as your user-item interaction data grows." Do I get the similar items with other tool.like Lucene,can Mahout do it without preference data at start?
