| Abstract(in English) | In this report, we propose efficient information searching methods based on user's utility in super distributed environments, where the released information can be renewed or deleted freely by administrators of the independent information sites. Efficient searching methods mean that the searcher can find the information he/she wants (we call it "target information") with his/her high utility or satisfaction. Generally, the more the searching time and the other costs pile up and therefore target discovery probability rises up, the less user's utility becomes. Then we propose some efficient searching methods considering user's utility in the case of the search for plural number of targets at the same time. In these methods, focusing on that the user's utility decreases monotonously, we give high priority to the search which decreases its utility sharply. Moreover, we show the effectiveness of the proposed methods by computer simulations. |
