Abstract

In the present invention, when a request query is different in expression from a viewpoint of a target content description, using a term exchange description in which a term contained in the content description and another term indicating in different expression the term are associated with each other and described, the request query or the viewpoint of the target content description is exchanged with the same term as the viewpoint or request respectively to perform content retrieval. In this way, without describing a plurality of viewpoints in a content description, it is possible to increase the number of expressions for use in request query, and to suppress the redundancy of content description.

Description

[0001] The patent application for this invention is a divisional application of the following patent application: [0002] Application number: 03108518.0 [0003] Application date: March 28, 2003 [0004] Title of Invention: Content Retrieval Device and Method technical field [0005] The present invention relates to a content retrieval device and method for retrieving a content description, which is the content of multimedia content (hereinafter referred to as content), such as video, audio and text. Background technique [0006] MPEG-7 has been standardized as a description interface for retrieving and filtering multimedia content, including video and audio, which cannot be retrieved conventionally. Therefore, it is possible to create various content descriptions using description profiles based on the XML schema standardized by W3C. Therefore, the use of MPEG-7 is about to start in broadcasting, cellular communication, the Internet, and the like. [0007] Next, the pr...
