چکیده
Three ad hoc runs were submitted: long (title, description and narrative), medium (title and description) and short (title only). \Blind" expansion was used for all runs. The queries from the medium ad hoc run were reused for the small web track submission. Most of the negative expressions were removed from the narrative eld of the topic statements, and a new expansion term selection procedure was tried.

Experimental results are given in terms of word error rate and average precision for both the SDR’98 and SDR’99 data sets. In addition to the Okapi approach, we also investiged a Mar...

متن کاملMultiText Legal Experiments at TREC 2008
Our TREC 2008 e ort used fusion IR methods identical to those used for our TREC 2007 e ort; in addition we used logistic regression to attempt to learn the optimal K value for the primary F1@K measure introduced at TREC 2008. We used the Wumpus search engine combining several methods that have proven successful, including cover density ranking and Okapi BM25 ranking, and combination methods. St...
