> Currently while running the itembased recommender from the command line, user
> can get recommendation for a particular set of users by using the userFile
> option or for particular set of itemId's by using the itemFile option. Using
> these option together seems to provide recommendations for the cross product
> for the two inputs. We need an option say userItemFile where a coma separated
> userid,itemid pair is provide on each line as input and output will be
> userid,itemid,recommendation. This functionality will be very useful for lot
> users.
