Abstract

Wikipedia is a famous online encyclopedia. However most Wikipedia entries are mainly explained by text, so it will be very informative to enhance the contents with multimedia information such as videos. Thus we are working on a method to extend information of Wikipedia entries by means of broadcast videos which explain the entries. In this work, we focus especially on news videos and Wikipedia entries about news events. In order to extend information of Wikipedia entries, it is necessary to link news videos and Wikipedia entries. So the main issue will be on a method that labels news videos with Wikipedia entries automatically. In this way, explanations could be more detailed with news videos can be exhibited, and the context of the news events should become easier to understand. Through experiments, news videos were accurately labeled with Wikipedia entries with a precision of 86% and a recall of 79%.
