net.myrrix.common.MyrrixRecommender.recommendedBecause()

Lists the items that were most influential in recommending a given item to a given user. Exactly how this is determined is left to the implementation, but, generally this will return items that the user prefers and that are similar to the given item.

This returns a {@link List} of {@link RecommendedItem} which is a little misleading since it's returningrecommending items, but, I thought it more natural to just reuse this class since it encapsulates an item and value. The value here does not necessarily have a consistent interpretation or expected range; it will be higher the more influential the item was in the recommendation.

@param userID ID of user who was recommended the item @param itemID ID of item that was recommended @param howMany maximum number of items to return @return {@link List} of {@link RecommendedItem}, ordered from most influential in recommended the given item to least

      return;
    }


    MyrrixRecommender recommender = getRecommender();
    try {
      Iterable<RecommendedItem> similar = recommender.recommendedBecause(userID, itemID, getHowMany(request));
      output(request, response, similar);
    } catch (NoSuchUserException nsue) {
      response.sendError(HttpServletResponse.SC_NOT_FOUND, nsue.toString());
    } catch (NoSuchItemException nsie) {
      response.sendError(HttpServletResponse.SC_NOT_FOUND, nsie.toString());
