Abstract

An information processing apparatus which allows high-quality contents to be easily obtained. A WWW browser section sends search request information which includes a keyword for web pages, input by the user, to an evaluation and search server. A search section of the evaluation and search server receives the search request information through a transmitting and receiving control section, and searches a WWW data base for web pages corresponding to the reported keyword. The search section reports the URLS, access information, of web pages obtained as a search result, to an evaluation section to request the calculation of an evaluation value for each web page. The search section generates search result information including evaluation from the access information of the web pages obtained as a search result and the evaluation value for each web page, and sends it to the WWW browser section through the transmitting and receiving control section.
