<p>In television receivers and similar systems, user profiles (301, 302, 303, 311, 312, 313, 321, 322, 323) are needed for use with interactive agents which suggest or recommend content. The invention relates to a method and system for determining a user profile for a user. A first set (30) of profiles is presented, from which the user makes a selection. Next 'generations' (31, 32) of profiles are created based upon previous ones, preferably using a genetic algorithm. Each next generation (31, 23) will be more suited to the user's preferences, because the relevant attributes are passed on to this next generation. Presentation of the profiles can be adapted to the attributes, so that the user can visually recognize each profile and make a more informed selection.</p> |
