在数据处理时代，新闻视频是信息的富矿。毕竟，新闻本质上是为了向公众传达信息而创造的。但是，我们能超越直接呈现给我们的东西，看到更广阔的图景吗？许多作品已经关注我们可以从多年的新闻广播分析中发现和理解什么。这些分析带来了对公众人物活动的监测和理解，政治策略，对关键媒体事件的解释甚至预测。这些工具可以帮助公众人物管理其公众形象，并支持记者、社会科学家和其他媒体专家的工作。新闻分析还可以从复杂系统的透镜来看待，随着时间的推移收集多种类型的实体、属性和交互。由于许多公众人物介入不同的新闻故事，第一个有趣的任务是观察这些演员之间的社会互动。为了实现这一目标，我们建议使用视频分析自动化的过程中，直接从新闻视频档案构建社交网络。在本文中，我们将介绍一个系统，从新闻视频中的人脸检测派生出多个社交网络。我们目前的初步结果，这些网络的分析，通过监测活动的100多个公众人物。最后，我们使用这些网络作为政治研究的支持，我们提供了日本公共广播公司NHK在过去十年的晚上7点新闻档案所呈现的政治格局的概述。
In the age of data processing, news videos are rich mines of information. After all, the news are essentially created to convey information to the public. But can we go beyond what is directly presented to us and see a wider picture? Many works already focus on what we can discover and understand from the analysis of years of news broadcasting. These analysis bring monitoring and understanding of the activity of public figures, political strategies, explanation and even prediction of critical media events. Such tools can help public figures in managing their public image, as well as support the work of journalists, social scientists and other media experts. News analysis can also be seen from the lens of complex systems, gathering many types of entities, attributes and interactions over time. As many public figures intervene in different news stories, a first interesting task is to observe the social interactions between these actors. Towards this goal, we propose to use video analysis to automatise the process of constructing social networks directly from news video archives. In this paper we are introducing a system deriving multiple social networks from face detections in news videos. We present preliminary results obtained from analysis of these networks, by monitoring the activity of more than a hundred public figures. We finally use these networks as a support for political studies and we provide an overview of the political landscape presented by the Japanese public broadcaster NHK over a decade of the 7 PM news archives.
