Development of a search engine for the indexing and retrieval of data from the TV production archive of ZDF

电视、电影和广播制作的学术研究近年来蓬勃发展。这是因为长期以来在文化上具有巨大影响力的AV（视听）媒体越来越引起研究者的兴趣。公共广播公司设有节目和专题节目的制作档案，这些档案构成了德国的视听文化资产。然而，传播和媒体研究领域的研究人员目前无法方便地在线访问这些档案。因此，莱比锡大学图书馆正在开发一个基于搜索引擎的应用程序，该程序将对公共服务电视广播公司ZDF的档案数据进行编目，然后通过生成结果列表和创建图形可视化等方式使其可用于学术研究。该项目的一个关键目标是处理与文化遗产有关的广播数据，并将其提供给研究，同时确保这些数据不会被用于非法目的。该项目旨在使ZDF档案以这样一种方式访问，即除了探索个别特征和制作外，还可以对整个制作进行研究。类似于德国国家书目，它只包括出版的项目，只有制作已分发的某种形式的广播公司（例如，已经在一个或多个场合广播或以其他方式公开提供）将由应用程序解决。狭义的目标是为研究人员提供两种形式的数据检索：a）档案检索，以及B）使用目录数据的复杂检索查询，其中研究数据通过分析、显示和导出选项生成。这反过来又为学术用途开辟了两种可能性。首先，公共广播公司的制作档案首次可以在外部进行搜索。其次，由于该指数将超越单纯的库存功能，它将在检索研究数据时创造额外的附加值。这可以被视为一个试点项目，因为计划中的应用程序理论上可以用于其他数据提供者，因此可以扩展为可能的“德国媒体”。该项目利用莱比锡大学图书馆的专业知识开发和运行媒体-特定搜索引擎它还将利用在图书馆运营的“adlr.link”媒体、传播和电影研究专业信息服务中注册的研究人员的专业知识。

The academic study of television, film and radio productions has gown strongly in recent years. This is because AV (audio-visual) media, which have long been culturally very influential, are increasingly attracting the interest of researchers. The public broadcasting corporations have production archives where programmes and features are stored and which constitute an AV cultural asset of Germany. However, researchers working in communication and media studies do not currently have user-friendly online access to these archives.Leipzig University Library is therefore developing a search engine based application that will catalogue archive data from public-service TV broadcaster ZDF and then make it accessible for academic research, including by generating lists of results and creating graphical visualizations. One key goal of the project is to process broadcast data which is relevant to cultural heritage and make it available for research while ensuring that the data cannot be used for illicit purposes. The project aims to make the ZDF archive accessible in such a way that as well as exploring individual features and productions, research can be conducted regarding production as a whole. Similar to the German National Bibliography, which solely includes published items, only productions which have been distributed in some form by the broadcaster (e.g. which have been broadcast on one or more occasions or made publicly available in some other way) will be addressed by the application.The narrow aim is to enable two forms of data retrieval for researchers: a) an archive search, and b) a complex search query using the catalogue data, with research data generated by means of analysis, display and export options. This in turn will open up two possibilities for academic use. For one thing, for the very first time it will be possible for a public broadcaster’s production archive to be searched externally. And secondly, since the index will go beyond the function of a mere inventory, it will create additional added value when retrieving research data.This can be regarded as a pilot project because the planned application can theoretically be used for other data providers and could thus be expanded into a possible ‘German mediography’.The project makes use of the expertise of Leipzig University Library for the development and operation of a media-specific search engine. It will also harness the expertise of researchers registered in the ‘adlr.link’ Specialized Information Service for Media, Communications and Film Studies operated by the library.
