Problems solved by technology

[0005] Inconsistent ratings can lead to poor recommendations, distrust of recommenders and ultimately high user dissatisfaction
[0006] Another problem with discrete scales is that user tastes and rating criteria evolve over time

Embodiment Construction

[0018] Such as figure 1 As shown, a system 100 of an embodiment of the present invention includes a processor device 101 connected to a storage device 103 . The storage means 103 may be a memory integrated with the processor means 101 or a separate memory means such as a CD-ROM or an external storage means such as a library held on a server and accessed remotely eg via the internet. The processor means 101 are also connected to an interface device 105 and a display 107 . Interface device 105 may be a remote control device or mouse that allows a user to interact with display 107 . Alternatively, the interface device may include a touch sensitive screen, keypad or the like. The display may be a television screen, a computer screen or the screen of a handheld device such as a PDA, mobile phone, MP3 or the like.

[0019] now refer to figure 2 The operation of the system is described in detail. When a new item is available for rating, step 201 , the new item is presented to t...

Abstract

Items are rated for use in a recommender. A record of a plurality of previously rated items and their associated ratings is maintained and upon receiving a rating for a first item (201), at least one of the rated items is retrieved (205) having a similar rating to the rating of the first item. The retrieved at least one rated items is displayed (207). The user may then change rating of the first item or the retrieved items (209) in order to apply the ratings consistently.

Description

technical field [0001] The present invention relates to methods and systems for rating items. In particular, but not exclusively, the invention relates to item ratings for a recommender system to enable the system to learn a user's preferences. Background technique [0002] Recommenders are becoming increasingly popular as a tool to obtain only those items that a user (or user group) likes from a large number of items such as audio / video content libraries, product catalogs, etc. These recommenders are typically provided as stand-alone services (eg Movielens) or as add-ons to existing services (eg Amazon, iTunes). They are increasingly appearing in consumer devices such as TiVo DVRs. [0003] These recommender systems need to get feedback from users to understand their hobbies. Typically, users are asked to rate items on a given discrete scale, often a 5, 7 or 11 point scale. [0004] Unambiguously rating items on a 5, 7 or 11 point scale can be challenging for many users...
