Add rating recommendation for a single user-item pair
I can see ' Ranking ' build type in a sample but it seems to not be fully implemented yet. I would like to know a ranking for a user-item pair.
For example, taking into account historical data, I would like to know that particular content is recommended to the exact user with a ranking X (like 0.72). Additionally this could be executed also in a batch proces for a list of provided items. I'm note sure if the last proposition is already feasible with user recommendations and 'itemIds' parameter ?
