Abstract: In this report we describe our approach to the known-item search task for TRECVID 2012. We describe how we index available metadata and how we gain additional information about the videos using content-based analysis. A rule-based query expansion and query reduction method is applied to increase the number of relevant videos in automatic runs. Furthermore, we describe an approach for quick, interactive filtering of large result sets. We outline how the parameters of our system were tuned for the IACC dataset and discuss our TRECVID 2012 KIS results.

Abstract: In this paper, we investigate whether community-contributed multimedia content can be used to make video summaries of social events. We implemented an event summarization algorithm that uses photos from Flickr and videos from YouTube to compose summaries of well-known society events, which took place in the last three years. The comparison with a manually obtained ground truth shows a good coverage of the most important situations of these events. We do not claim to produce the best summaries possible, which may be compared to the work of a human director, but we analyze what can be achieved with community-contributed content by now.

Abstract: Default image browsing interfaces on touch-based mobile devices provide limited support for image search tasks. To facilitate fast and convenient searches we propose an alternative interface that takes advantage of 3D graphics and arranges images on a rotatable globe according to color similarity. In a user study we compare the new design to the iPad's image browser. Results collected from 24 participants show that for color-sorted image collections the globe can reduce search time by 23% without causing more errors and that it is perceived as being fun to use and preferred over the standard browsing interface by 70% of the participants.
