A database building method for multimedia contents is provided. The database building method for multimedia contents has the steps of (a) accessing an arbitrary site providing multimedia contents through a telecommunications network; (b) calling multimedia contents in by spidering the site; and (c) classifying the multimedia contents data according to the stored addresses and storing them in a predetermined database. Using category information on the corresponding sites, the database building method for multimedia contents according to the present invention semantically classifies multimedia contents and stores them in the corresponding databases. In the database built by the database building method for multimedia contents according to the present invention, multimedia contents which are dispersed on the WWW are well collected and, using category information or URL information, are semantically well classified. Therefore, various method for retrieving multimedia contents can be used so that wanted multimedia contents can be retrieved fast and efficiently.

1. Field of the Invention
The present invention relates to classification of multimedia data, and more particularly, to a database building method for multimedia data (hereinafter, referred to as multimedia contents) in which multimedia contents are semantically classified and stored in a predetermined database.
2. Description of the Related Art
The above objects and advantages of the present invention will become more apparent by describing in detail a preferred embodiment thereof with reference to the attached drawings in which:
FIG. 1 is a block diagram showing the structure of a database building apparatus for multimedia contents according to an embodiment of the present invention;
FIG. 2 is a flowchart showing the major steps of a database building method for multimedia contents according to an embodiment of the present invention used in the apparatus of FIG. 1;
Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings. The present invention is not restricted to the following embodiments, and many variations are possible within the spirit and scope of the present invention. The embodiments of the present invention are provided in order to more completely explain the present invention to anyone skilled in the art.
According to the present invention, multimedia contents are semantically classified so that retrieval or browsing can be efficiently done. For example, multimedia contents corresponding to “F-16 fighter” can be classified in a category referred to as “Gulf War”. For this, the merit of the structure categorized in a retrieval site is used. For example, retrieval sites such as Yahoo TM have a categorized structure. For example, a text categorized by “movie” is clicked on, collected information of more detailed sites related to movies in text formats categorized such as “erotic”, “action”, or “human episode” is provided. Also, the addresses of detailed sites related to respective movies can be provided. The classification of such retrieval sites and portal sites are well done semantically. Therefore, the present invention uses the categorized structures of such retrieval sites and portal sites in making a database for multimedia contents.
FIG. 1 is a block diagram showing a database building apparatus for multimedia contents according to an embodiment of the present invention. FIG. 2 is a flowchart showing the major steps of a database building method for multimedia contents according to an embodiment of the present invention used in the apparatus of FIG. 1. FIG. 2 will be frequently referred to in the following explanation.
