Innovative Exploration of Scientific videos: The TIB AV-Portal

In addition to the scientific core tasks, the dimension of transfer and scientific infrastructure services is becoming increasingly important. According to the German Wissenschaftsrat, transfer does not only include technological transfer. Transfer also includes the communication of scientific findings into society, culture, business, and politics. In order to use research findings in other areas of society, results must be accessible, searchable, citable and brought together across disciplinary boundaries.

Traditionally, scientific results are published in conference proceedings, documenting the current state of research. Additionally, an increasing number of conferences, workshops and symposia are recorded and the videos are subsequently published. While libraries have well established procedures for collecting textual conference reports, comparable procedures for scientific videos have not yet been established. In most cases these videos are published on commercial platforms like YouTube and Vimeo or on conference website. A systematic search for conference recordings is difficult e.g. because the URL changed over time or external links lead to nowhere, because conference websites are no longer maintained. In order to prevent the loss of scientific videos the Leibniz Information Centre for Science and Technology has developed the AV Portal. The AV Portal provides the ideal infrastructure to host, find and reuse scientific videos including conference recordings. 

The portal's key unique selling points are the long-term archiving of all videos and the seamless use of Digital Object Identifiers (DOI) and Media Fragment Identifiers (MFID), which ensure reliable long-term availability and referencing of the videos to the second. In addition, the AV-Portal contains various automated analysis methods, through which the videos can be accessed on a segment-level as well as time-based: Keyframe-based text recognition (Video OCR), Speech recognition for the creation of audio transcripts, annotation with predefined visual concepts as well as semantic analysis. With the help of these analysis procedures, information in a video can be precisely localised using semantic and explorative search functions, videos can be searched by content and relevant video segments can be identified and called up segment by segment. A cross-lingual mapping (German-English) of the semantic knowledge base also allows the videos in the portal to be searched across multiple languages.
