University of Waterloo at INEX2007: Adhoc and Link-the-Wiki Tracks

摘要

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.
