PROBLEM TO BE SOLVED: To visualize a cluster of users represented by a document selected from a collection of documents. SOLUTION: A plurality of users selected in a user group are identified, and the plurality of users share interest decided through multi-mode collection use analysis. For each user of the plurality of users, a corresponding access probability representing the frequency of user's access to documents for each document in a document collection is decided. For each document in the document collection, a set access probability in the plurality of selected users corresponding to the probability that a user in a plurality of selected users accesses the document is computed. A disk tree having a plurality of nodes each representing a document in the document collection is displayed. Each node in the disk tree having a set access probability larger than a desired threshold value is highlighted. COPYRIGHT: (C)2010,JPO&INPIT
