METHOD AND APPARATUS FOR MODIFYING A USER PREFERENCE PROFILE

摘要

A user preference profile apparatus comprises a receiver (301) which receives preference indications from a plurality of devices (101-105) which have different device characteristics. The received preference indications are implicit preference indications reflecting user actions for content items. A relation processor (305) provides device dependent relations for devices where each device dependent relation defines a calculation of a device content item preference as a function of at least one preference indicator from the corresponding device. A preference processor (303) generates a device content item preference for content items and devices in response to received preference indications for the content items and devices and the corresponding device dependent relation. A user profile processor (307) then modifies a user preference profile in response to the content item preferences. The invention may facilitate or improve the generation of a device non-specific user profile by compensating for the impact of device specific characteristics of the devices used by a user.
