Embodiment Construction

[0067] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation methods and specific operation processes are given, but the protection scope of the present invention is not limited to the following embodiments.

[0068] Such as figure 1 As shown, a tag management method based on ontology library can mark media assets through multi-layer semantic tag extraction, dynamically update semantic tags based on ontology reasoning rules, and tag search method based on ontology library is conducive to improving the quality of media assets. management efficiency.

[0069] The extraction of the multi-layer semantic label is specifically:

[0070] A1) The user submits the image database to the multi-layer semantic tag library module through the management terminal;

[0071] A11) The user upload...

Abstract

The invention relates to an ontology library-based tag management method. Media asset tagging is realized through multilayer semantic tag extraction; and semantic tag management is realized based on an ontology reasoning rule. A user uploads a picture to a picture database through a management end; the picture is processed through an ontology-based multilayer semantic tag library generation module to obtain a multilayer semantic tag; and the multilayer semantic tag is stored in an ontology tag library. A new tag submitted by the user is processed through an ontology reasoning rule-based tag library generation module. Firstly the new tag is added to existing tag library contents to obtain a mixed tag library; secondly according to the reasoning rule, the mixed tag library is processed to obtain an optimal ontology; and finally, the optimal ontology is stored and the ontology library is updated. The user submits query information to the tag library for query during use, and if the query is hit, a tag query result is returned to the user; or otherwise, the query information is subjected to similarity calculation through a similarity calculation module to obtain related recommendation information of the query information, and the related recommendation information of the query information is returned to the user.

Description

technical field [0001] The invention relates to the field of media asset management, in particular to a tag management method based on an ontology library. Background technique [0002] One of the manifestations of the advent of the big data era is that digital media assets represented by text, pictures, audio, and video have seen a surge in data volume and content diversity. At the same time, people’s awareness and utilization of digital media assets are also increasing. More frequently, digital media assets are widely used in the public and various industries in various application forms, especially in the aspect of media asset management. [0003] At present, in the application industry related to digital media asset management, existing management methods need to rely on tag information attached to media resources to provide users with retrieval services, and all adopt text-based tag or content-based tag management methods. The text-based tag management method is a keyw...
