Abstract
A weight processor 120 selects keywords that match a plurality of phrases extracted from an accessed file, from a keyword storage unit 110. The processor 120 determines a priority keyword based on the weights linked to the selected keywords. A useful information selector 150 selects useful information for use by the user and associated with the priority keyword, from a useful information storage unit. A feedback receiving unit 154 receives from the user an input for evaluation indicating whether user is interested in the content of the file. A weight adjusting unit 156 adjusts the weight linked to the keyword selected by the weight processor 120, based on the input evaluation, and records the adjusted weight in the keyword storage unit 110.
