Abstract

Disclosed is an apparatus and method for retrieving multimedia contents represented in a Moving Picture Experts Group (MPEG) 7 by transforming a user query into an MPEG-7 query format. The method for retrieving multimedia contents includes: representing a user query by using an indicator indicating a specific region of a Moving Picture Experts Group 7 (MPEG-7) document and a reference for referring to the indicator; analyzing a meaning of the user query represented by using the indicator and the reference to thereby produce an analysis result; and retrieving multimedia contents according to the analysis result. The present research can satisfy more than two retrieval conditions within the same structure in an MPEG-7 query format and it can also clearly represent that two different MPEG-7 documents are referred to. Since the meaning of a user query is analyzed accurately during retrieval process, it is possible to precisely retrieve multimedia contents.

Description

technical field [0001] The present invention relates to apparatus and methods for retrieving multimedia content; and more particularly, to multimedia content that can be retrieved based on MPEG-7 representations by transforming user queries into the Moving Picture Experts Group 7 (MPEG-7) query format Content retrieval device and method thereof. [0002] This work was supported by MIC / IITA's IT R&D Program [2005-S-117-03, "Development of Intelligent Personal Media Management Technology for Ubiquitous Environment"]. Background technique [0003] Moving Picture Experts Group 7 (MPEG-7) is an international standard concerning the structure of metadata representing multimedia information such as images, audio, and moving pictures. The MPEG-7 query format is used to retrieve multimedia content based on MPEG-7 representations. The MPEG-7 multimedia content retrieval system retrieves multimedia content associated with queries entered in accordance with the MPEG-7 query format. ...
