L3S Research Center at TREC 2006 Enterprise Track

چکیده
The L3S Research Center submitted four runs at Enterprise Track for the first time in 2006, all of them are based solely on the W3C mailing lists. The first run serves as a fully automatically produced baseline. The second run uses a threshold on the document scores to limit the number of documents used for expert ranking. The third uses in addition a threshold on the experts scores in order to decide how many experts to retrieve. Our last run exploits the manually assigned topic specificity values, which predicts a number of relevant expert for each query. The results show that the simple threshold techniques outperform the baseline, while the current definition of query specificity does not improve the result quality.
