Around 70 % of tablet and smartphone owners use their devices while watching television [11]. This allows broadcasters to provide consumers with additional background information that they may bookmark for later consumption in applications such as depicted in Figure 1.

We present an approach for automatically generating links to background information in real-time, to be used on second screens. We base our semantic linking approach for television broadcasts on subtitles and Wikipedia, thereby effectively casting the task as one of identifying and generating links for elements in the stream of subtitles. The process of automatically generating links to Wikipedia i
