Abstract:
PROBLEM TO BE SOLVED: To enable information recommendation precision to be enhanced by automatically extracting an optimal context condition.SOLUTION: A global context/context ID setting part 117 collects context conditions related to content browsing. A divided context extracting and processing part 116 divides an interest model into tables for combination, on the basis of the combinations of the collected context conditions, and extracts a table to be updated from the tables for each combination, on the basis of a relationship between the context conditions included in the combinations, to calculate a weight for the table to be updated on the basis of the relationship. An interest model updating and processing part 130 updates a user interest score with respect to a concept of the table to be updated by using a feature score calculated from content browsing history and the weight.
