Digital media content and resource integration and sharing method in cloud environment

Abstract

The invention relates to a digital media content and resource integration and sharing method in a cloud environment. The method mainly comprises the steps that a unified view is established in order to solve the problem that the distribution of digital media resources is relatively independent, scattered and closed, so as to integrate and share the digital media data; extendable digital media resource bodies in different fields are constructed with WordNet as a blueprint of the bodies; a digital media semantic expression method is established to support the marking of digital media cloud materials at different grain sizes, so as to manage and use the digital media cloud materials in a unified way. According to the digital media content and resource integration and sharing method in the cloud environment, non-local digital media resources and databases are integrated, the effective sharing, organization, management and processing of digital media resources are realized, and digital media material semantic marking and searching at different grain sizes are supported.

Description

technical field [0001] The present invention relates to the technical fields of virtual reality, knowledge expression and database, in particular to a method for integrating and sharing digital media content resources in a cloud environment, specifically for the integration and sharing of digital media cloud materials, material library construction and digital media semantic expression method. Background technique [0002] Digital media is an interdisciplinary comprehensive technology. It is dominated by information science and digital technology, based on mass communication theory, and guided by modern art. It applies information communication technology to the fields of culture, art, business, education and management. , including graphics and image processing technology, human-computer interaction technology, virtual reality technology and mass media technology, etc., with obvious multi-disciplinary, multi-field and multi-directional technical cross characteristics.

AI Technical Summary

Problems solved by technology

When users search digital media resources, they focus on the semantic information contained in the resources, which can be described in natural language and is easy for users to understand and express. However, traditional queries are performed at the level of symbol matching. On the one hand, they do not fully expand the user's Query intent also ignores the rich semantic information of digital media materials, and semantic query can fundamentally improve the performance of information retrieval, which requires effective knowledge-based semantic description of massive digital media resources in the cloud environment, that is, resources Annotation and representation
