ITEC-UNIKLU Known-Item Search Submission 2012

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 contentbased 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.
