With the advance of computer technology, it is getting more frequent for users to treat mass information more and more frequently. Its order to treat mass information, it is important for the users to incorporate information filtering and information visualization technique effectively. That is, the visualization method which effectively visualize5 the importances, which are obtained by an information filtering system, is required. In this paper, we propose a method for evaluating information visualization methods in the point of the method reflecting the importance of each object.
