Title:
情報分類装置および情報検索装置
Document Type and Number:
Japanese Patent JP4808736
Kind Code:
B2
Abstract:
An information retrieval device and the like are provided to quickly retrieve information desired by a user even when information is collected based on the user's taste or interest. Each of sort item generating units (121 to 12N) sorts information into plural sort items based on different sorting aspects (details or attributes of information), and a category generating unit (13) combines the sort items into various categories. A category-combination searching unit (14) combines a predetermined number of the categories to generate category combinations to which information of the most equivalent in number belongs. When information is narrowed down using the category combinations, the number of operations for arriving at target information to be retrieved by the user (specifically, the number of operations for selecting categories or for searching target information to be retrieved in the categories) can be minimized, thereby enabling much faster retrieval.
