The invention relates to generation of a user profile for applications and/or services such as e.g. recommendation of content items. Initially, a first user profile is generated at a first user device for a first user. The first user device furthermore stores user contacts for the first user with the user contacts being associated with a social network of the first user. A set of user devices associated with a set of user contacts of the stored user contacts is then determined and at least part of the first user profile is transmitted to this set of user devices. At least one user device generates user profile feedback which is transmitted back to the first user device. The first user device then modifies the first user profile in response to the received user profile feedback. The invention may allow a fast generation of an initial user profile with improved accuracy. |
