BRIDGE: Building Rich Links to Enable Television History Research
BRIDGE addresses access to television archives. Television is not an isolated medium, but a key node in a complex information landscape. From an exclusive focus on producing radio, television and publishing program guides, broadcasting organisations have moved to cross-media production companies where users are directly involved in online follow-up discussions. To be meaningful, these additional materials need to be cross-linked to the traditionally archived television materials so as to arrive at a meaningful web of information.
The project will develop, test and deploy efficient, effective and robust methods for automatically creating meaningful links between dynamically expanding archived television data and other information sources that are centered around entities, themes and events.
Our work takes the identification of entities, themes and events as its starting point. For entities we will adopt a data-driven approach, which will utilize the Sound and Vision cataloguing system and Wikipedia. For theme classification, we aim to develop scalable methods to automatically acquire training data on a broad spectrum of topics. For event detection and normalization we will mainly use the repetition of stories covering the same event by leveraging their intrinsic threaded structure. Then, we will use generative and discriminative approaches to create and classify links using entities, themes, and events as link sources, while link targets can be documents or arbitrary text snippets. A historic study into the position of migrants using the developed tools will complement and inform our system-centered work.
In May 2009, Marc Bron joined BRIDGE as a PhD student. The team was extended with Andrei Vishneuski, a scientific programmer, in the fall of 2009, while Jasmijn van Gorp (Utrecht University) joined the team as a postdoc at the start of year 2, in May 2010.
BRIDGE is part of the NWO-funded CATCH-programme, a collaboration between ILPS (UvA), Centre for Television in Transition (Utrecht University) and the Netherlands Institute of Sound and Vision.
