Abstract
During initialization of an explicit user profile for a recommender system, the user rates only one or more supersets of attributes and/or one or more consistently recurring attributes from the total set of attributes which may be employed by the recommender system to generate suggestions. While viewing lists of subject matter to which the recommender system relates at any time thereafter, the user may view and manipulate individual ratings for all attributes associated with a particular list item. The explicit profile is updated by addition of the item and associated rating value or replacement of the current rating value with the new value entered by the user. The profile may be supplemented with implicit ratings based on the user's viewing history.
Claims21
A search system comprising:
- an explicit user profile containing user-specific ratings for a plurality of attributes, wherein a user provides rating values for only a subset of the plurality of attributes during initialization of the explicit user profile;
- a recommender system employing the explicit user profile in evaluating each of a plurality of search items;
- and
- a controller enabling the user, while viewing information regarding an item subject to evaluation by the recommender system after initialization of the explicit user profile, to manipulate ratings values for each of the plurality of attributes associated with the item.
A content reception system comprising:
- an input for receiving content and a plurality of information items regarding the content;
- an explicit user profile containing user-specific rating values for a plurality of attributes, wherein a user provides rating values for only a subset of the plurality of attributes during initialization of the explicit user profile;
- a recommender system employing the explicit user profile in evaluating each of the plurality of information items;
- and
- a controller enabling the user, while viewing an information item after initialization of the explicit user profile, to manipulate rating values for each of the plurality of attributes associated with the item.
A method of searching information items comprising:
- receiving content and a plurality of information items regarding the content;
- employing an explicit user profile containing user-specific rating values for a plurality of attributes in evaluating each of the plurality of information items, wherein a user provides rating values for only a subset of the plurality of attributes during initialization of the explicit user profile;
- and
- allowing the user, while viewing an information item after initialization of the explicit user profile, to manipulate rating values for each of the plurality of attributes associated with the item.
A signal comprising:
- a listing of content suggestions relating to content and a plurality of information items regarding the content,
- wherein the listing of content suggestions is generated by employing an explicit user profile containing user-specific rating values for a plurality of attributes in evaluating each of the plurality of information items,
- wherein a user provides rating values for only a subset of the plurality of attributes during initialization of the explicit user profile,
- wherein the user, while viewing an information item after initialization of the explicit user profile, is permitted to selectively manipulate rating values for each of the plurality of attributes associated with the item.
