An uniform description and search method for multimedia element data

Abstract

The invention belongs to the computer technical field, and relates to a digital multi-media metadata uniform description facing to mass multi-media information resource management, being capable of expanding and maintaining, supporting large-scale disposition application and facing to an index and the retrieval method thereof. Based on the ontological idea, the uniform description method is a metadata description standard for integrating the media resource through combining a resource description frame and a XML; essential metadata is based on 15 basic elements defined by a Berlin core set DC to make a basic index; expanding metadata is the signalment data of being self-expanded by users or of unstructured multi-media data to make an expanding index. When in searching, firstly, the basic index is searched; then, the expanding index is searched. The invention can be applied to the system or platform for the processing of cataloguing, uploading, searching, exchanging, etc. to the multi-media information resource.

Description

technical field [0001] The invention belongs to the field of computer technology, and is an index-oriented digital multimedia metadata (Metadata) unified description and retrieval method that is scalable and maintainable for massive multimedia information resource management and supports large-scale deployment applications. The invention can be applied to a system or platform for cataloging, uploading, retrieving, exchanging and other processing of multimedia information resources. Background technique [0002] There are many kinds of multimedia information resources on the network, which can be mainly divided into four aspects: image, video, text and audio. These four aspects have their own resource description forms according to different formats, characteristics, and application purposes, and there are connections and interactions between different resources. A reasonable and unified description and definition of them is the basis for resource management and application d...

AI Technical Summary

Problems solved by technology

[0017] (1) Without a definite framework, it is difficult to make a unified description of various types of multimedia resources

[0018] (2) If a multimedia resource belongs to different types, then when making a unified description, there will be inconsistent cataloging specifications, and synonyms and polysemous words may occur, resulting in management disorder

[0019] (3) There is a lack of semantic association between items in the cataloging specification, and the resulting cataloging items are basically isolated, making it impossible to carry out further semantic queries

[0020] (4) If we integrate and manage multimedia information resources, in order to comply with different specifications, it will lead to more sub-items and more troublesome retrieval, which is not conducive to saving resources and improving performance

[0021] (5) A multimedia resource may need to be stored in several ways such as video, audio, picture, and text according to its different specifications, resulting in waste of resource space and difficulty in management

The management of media content is facing challenges such as business diversification and resource complexity

However, the organization and application forms of the old media resource information are relatively chaotic, with weak logic and poor scalability. They lack the necessary organizational framework for a variety of multimedia resources, and their identification and management capabilities are weak.
