20140257930 | EVALUATING TASTE PROXIMITY FROM A CLOSED LIST OF CHOICES - A system and method for estimating preferences or taste of users comprises a catalog having a closed number of items; a memory for storing distances between ratings of each pair of items; and a user interface to rate a subset of the items. The distances from the subset items to other items of the catalog give the user a preference for each item in the catalog despite never having rated these items. The catalog is ordered using the assigned preferences into a user preference vector, and is compared with vectors of other users to match up different users having similar preferences. Alternatively a distance measure can be defined between preferences of different users, with matching made between the users having the smallest difference. Initial distances may come from rating by a focus group or from application download data or other suitable sources. | 09-11-2014 |
