| 摘要: |
| 新闻视频关于新闻事件的报道是一种“多线程”的形式，针对这种特性提出了一种基于有向图理论的新闻视频数据库管理方法。研究了故事单元相似关系与图论知识之间的联系，结合最小部分树理论提出了一种将故事单元之间复杂相似关系图简化为“多线程”结构树的新闻视频数据库管理技术。实验显示，这种管理方法对于视频数据库的浏览、检索、摘要等实际需求具有重要的理论意义和应用价值。 |

| Abstract: |
| In order to incarnate “multithreading” of news event reporting, the paper studies the validity of graph theory for managing news video database. Firstly, news stories similarity and graph theory are studied for digesting complicated relations of all stories reporting the same event. Then, a method based on minimal spanning tree is presented for predigesting the similarity graph into a simple tree with “multithreads”. Experiments show that the method is a research issue with great theoretical and pratical significance for browsing, searching and abstracting in news video database. |
