In this paper, we describe University of Waterloo's ap- proaches to the Adhoc, Book, and Link-the-Wiki tracks. For the Adhoc track, we submitted runs for all the tasks, the Focused, the Relevant-in-Context, and the Best-in-Context tasks. The results show that we ranked first among all participants for each task, by the simple scoring of elements using Okapi BM25. In the Book track, we participated in the Book retrieval and the Page-in-Context tasks, by using the approaches we used in the Adhoc track. We attribute our poor performance to lack of training. In the Link-the-Wiki track, we submitted runs for both File-to-File and Anchor-to-BEP tasks, using PageRank [1] algorithms on top of our previous year's algorithms that yielded high performance. The results indicate that our baseline approaches work best, although other approaches have rooms for improvement.
