METADATA BASED INDEXING AND RETRIEVING APPARATUS AND METHOD

摘要

A metadata base index/search apparatus and a method thereof for improving search speed and search performance are provided to use a query for the metadata search generated from an inputted user query. A metadata extracting unit(10) extracts metadata from input data. A metadata indexing unit(20) produces index data in which a search object is from the extracted meta data. An index data storage by metadata(30) stores the generated index data according to meta data. A query analyzing unit of the quality produces the query for the metadata search from the query inputted from the user. A metadata searching unit searches index data corresponding to the query for the generated metadata search in the meta data index data storage module.
