摘要 提出了一种基于统计与可视化的新闻视频挖掘方法,在传统的新闻视频内容分析的基础上,结合数据挖掘中的统计与可视化技术,挖掘出大量新闻视频数据中的隐含信息,较好地实现了视频内容分析技术与数据挖掘技术的结合。根据新闻视频的特点,着重从时间以及空间的角度进行统计分析,并设计了两种可视化方法:时间趋势图以及时空分布图。实验证明,该方法对辅助决策人员做出正确的分析与决策具有重要意义。 A novel news video mining method based on statistic and visualization is proposed. It integrates news video analysis techniques with data mining techniques of statistic and visualization perfectly, and discovers the implicit information from large news videos. Considering news videos' characters, it statistics and analyses news videos from the point of view of time and space, and designs two visualization methods: time-tendency graph and time-space distribution graph. Experiments prove that this method is important and efficient in supporting decision-makers' finial decisions.
