Abstract
Disclosed is a contents information search control system that, when automatic search of contents, such as game software, is performed with a terminal, such as a cellular phone, according to a user's preference, can reflect a change in user's interest or expansion of a target range of an interest. A change in user's interest is quantitatively grasped as an interest vector, and when the interest vector satisfies a predetermined condition, a search condition is updated to reflect the change in the user's interest in a search condition. In addition, expansion of a target range of the user's interest is quantitatively grasped as distance information, and when the distance information satisfies a predetermined condition, the search condition is updated to reflect the expansion of the target range of the user's interest in the search condition. The interest vector or the distance information is calculated from an automatic search result on the basis of contents selected by a user, and updated as occasion demands.
