Abstract
This invention is to automatically extract noteworthy information from a large amount of information. First, a disclosure unit of an individual opinion such as a statement in a personal Web page or a bulletin board is extracted from collected content information, and information such as URL or statement number for specifying the disclosure unit of the individual opinion is registered. Next, an object such as company name or industry type of the individual opinion is specified. Then, the disclosed contents of the individual opinion are analyzed, so that an evaluation as to the object such as good evaluation or bad evaluation is specified. Besides, the reliability is determined based on referenced degree ranking and based on whether information to indicate the basis of the opinion or the identity of the speaker is included. Thus, the evaluation as to the object as characteristics of the individual opinion can be presented to requesters. Besides, for example, only a bad evaluation can be extracted from evaluations as to the object of the individual opinion. Furthermore, the opinion, which has a high influence degree and is noteworthy, can also be found based on the referenced degree ranking or the reliability.
