ABSTRACT:
A vector retrieval/generation/correction unit of a user terminal generates, corrects, and optimizes an inquiry vector on the basis of a vector profile, an inquiry history, a user model, and a user profile. On the other hand, a vector retrieval/generation/correction unit in an information center generates/corrects/optimizes a feature vector on the basis of a vector table, a search history, and a contents description database. In the information center, when an inquiry profile including an inquiry vector is transmitted from the user terminal, an adaptive searching process is executed. According to evaluation made by a contents evaluating unit, proper contents are retrieved from a contents database.
