Adhoc and Book XML Retrieval with Cheshire

摘要

For this year's INEX UC Berkeley focused on the Book track and also submitted two runs for the Adhoc Focused Element search task and one for the Best in Context task. For all of these runs we used the TREC2 logistic regression probabilistic model. For the Adhoc Element runs and Best in Context runs we used the "pivot" score merging method to combine paragraph-level searches with scores for document-level searches.
