中文简介: | 英国广播公司有一个非常大的节目档案,涵盖了广泛的主题。该档案馆保存着BBC机构记忆的重要部分,是英国和世界其他地区文化史的重要组成部分。这些节目或其中的一部分有助于为当前新闻事件提供有价值的背景和背景。然而,英国广播公司的档案目录并不是所有曾经播出的节目的完整记录。例如,它不包括自1932年以来一直在广播的英国广播公司世界服务。这使得在存档的这些部分中发现内容非常困难。在本文中,我们描述了一个基于语义Web技术的系统,该系统帮助我们在BBC档案中快速定位与当前新闻事件相关的内容,而不需要或几乎不需要预先存在的元数据。该系统由归档内容与语义网的自动链接、用户对结果数据的验证以及从BBC直播新闻字幕中提取主题驱动。直播新闻字幕和BBC档案之间的链接被用于动态可视化,使用户能够快速定位相关内容。然后,记者和编辑可以使用这些内容提供历史背景、背景信息和有关时事的支持性内容。 |
课程简介: | The BBC has a very large archive of programmes, covering a wide range of topics. This archive holds a significant part of the BBC’s institutional memory and is an important part of the cultural history of the United Kingdom and the rest of the world. These programmes, or parts of them, can help provide valuable context and background for current news events. However the BBC’s archive catalogue is not a complete record of everything that was ever broadcast. For example, it excludes the BBC World Service, which has been broadcasting since 1932. This makes the discovery of content within these parts of the archive very difficult. In this paper we describe a system based on Semantic Web technologies which helps us to quickly locate content related to current news events within those parts of the BBC’s archive with little or no pre-existing metadata. This system is driven by automated interlinking of archive content with the Semantic Web, user validations of the resulting data and topic extraction from live BBC News subtitles. The resulting interlinks between live news subtitles and the BBC’s archive are used in a dynamic visualisation enabling users to quickly locate relevant content. This content can then be used by journalists and editors to provide historical context, background information and supporting content around current affairs. |
