In this paper, we describe University of Waterloo’s approaches to adhoc and Link-the-Wiki tracks. For the adhoc track, we submitted runs for the focused and the best-in-context tasks. We again show that Okapi BM25 works well for XML retrieval. We also analyze why our element-based best entry point result is better than our passage-based counterpart. Finally, we present our baseline algorithm for embedding incoming and outgoing links in Link-the-Wiki track.


Query Term Outgoing Link Incoming Link Relevant Passage Focus Task 
These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
