基于视频单元的视频档案资源多维语义关联聚合研究

细粒度的视频档案资源语义关联聚合是视频档案资源精准化、知识化服务实现的基础。本文在分析当前我国视频档案资源聚合工作面临的主要问题的基础上，结合视频档案资源的特性，提出了基于视频单元的视频档案资源多维语义关联聚合思想，并界定了视频单元概念，阐释了基于视频单元的视频档案资源多维语义关联聚合含义与实现逻辑，设计了多维语义关联聚合实现框架。文章最后还从视频档案资源内容特征提取、语义关系优化、关联链接维护以及服务应用推进等层面提出了具体实现保障策略。

Research on Multidimensional Semantic Association Aggregation of Video Archives Resources Based on Video Unit

The fine-grained semantic association aggregation of video archive resources is the basis for the accuracy and knowledge of video archive resources. Based on the analysis of the main problems faced by the aggregation of video archive resources in China, the author in the paper puts forward the idea of multidimensional semantic association aggregation of video archive resources based on video unit, defines the concept of video unit, meaning and implementation logic of multidimensional semantic association aggregation of video archive resources based on video unit, and designs the framework of multidimensional semantic association aggregation. Finally, the author also puts forward specific implementation strategies from the aspects of content feature extraction, semantic relationship optimization, link maintenance and service application promotion.
