PoliMedia - Improving Analyses of Radio, TV & Newspaper Coverage of Political Debates

Analysing media coverage across several types of media-outlets is a challenging task for academic researchers. The PoliMedia project aimed to showcase the potential of cross-media analysis by linking the digitised transcriptions of the debates at the Dutch Parliament (Dutch Hansard) with three media-outlets: 1) newspapers in their original layout of the historical newspaper archive at the National Library, 2) radio bulletins of the Dutch National Press Agency (ANP) and 3) newscasts and current affairs programs from the Netherlands Institute for Sound and Vision. In this paper we describe generally how these links were created and we introduce the PoliMedia search user interface developed for scholars to navigate the links. In evaluation it was found that the linking algorithm had a recall of 67% and precision of 75%. Moreover, in an eye tracking evaluation we found that the interface enabled scholars to perform known-item and exploratory searches for qualitative analysis
