1. An information processing apparatus comprising:
extraction means for extracting interest data having a plurality of attributes indicative of a user's interest, an extracted interest data having first and second interest data;
comparison means for comparing a predicted degree of importance of the extracted interest data against a predetermined threshold, the second interest data having a predicted degree of importance lower than the predetermined threshold and corresponding to interest data which is expected not to interest the user, the first interest data having a predicted degree of importance higher than the predetermined threshold and corresponding to interest data which is expected to interest the user;
selection means for selecting only the second interest data having a predicted degree of importance lower than the predetermined threshold from among said extracted interest data extracted by said extraction means;
presentation means for presenting only said second interest data selected by said selection means which has a predicted degree of importance lower than the predetermined threshold;
dialogue means for receiving a response indicative of an actual degree of importance to the user of said second interest data presented by said presentation means which has a predicted degree of importance lower than the predetermined threshold; and
update means for updating said first and second interest data on the basis of a result of the response received by said dialogue means,
wherein said update means changes an order of said predicted degree of importance on basis of a result of said response received by said dialogue means.
