+In this paper, we describe our approach in PAN 2012 competition.
+Our candidate retrieval system is based on TODO Simon.
+
+Our detailed comparison system detects common features of both
+documents, computing valid intervals from them, and then merging
+some detections in the postprocessing phase. We also discuss
+the relevance of current PAN 2012 settings to the real-world
+plagiarism detection systems.
