Hi Darius,
There is no module called mahout-utils in mahout 0.8. The documentation you
referred to is prepared for mahout 0.4, it is outdated.
So if you want to use mahout 0.8, remove that dependency, mahout-core would
be sufficient.
But that wouldn't compile, since SlopeOneRecommender doesn't exist in
Mahout any more. You should replace it with another recommender, for
example, a neighborhood based recommender with a similarity measure that
supports boolean ratings.
An example modification for the tutorial you referred to works for 0.8:
REMOVE:
CachingRecommender cachingRecommender = new CachingRecommender (new
SlopeOneRecommender(model));
ADD:
UserSimilarity similarity = new CachingUserSimilarity(new
LogLikelihoodSimilarity(model), model);
UserNeighborhood neighborhood = new NearestNUserNeighborhood(10,
Double.NEGATIVE_INFINITY, similarity, model, 1.0);
CachingRecommender cachingRecommender = new CachingRecommender (new
GenericBooleanPrefUserBasedRecommender(model, neighborhood, similarity));
Best
Gokhan
