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-item

Embodiment Construction

[0050] The present invention has been effectively applied in the project "IPv6-based P2P content access middleware system for radio, film and television data". In this embodiment, the development computer is "DELL GX520, Intel(R) Pentium(R) 4 CPU 3.00GHz, 2GB memory, 80G hard disk". The development environment is Microsoft VisualStudio 2003, and the programming language is C#. The operating environment of the system is an operating system of Windows XP or above (installing Microsoft.NET Frameworkl.1).

[0051] First of all, the unified description method of metadata of multimedia information resources provides definition and normative information for digital multimedia content, organizes and manages the metadata of radio, film and television materials in a unified way, and provides basic support for the storage of massive resources.

[0052] Secondly, based on the ontology database, a basic index and an extended index database are established to support a certain degree of se...

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...
