TREC 2005 Genomics Track at I2R

I2R at TREC 2006 Genomics Track

This paper describes the method we used for the Genomics Track of TREC 2006. BM25 model is implemented to retrieve relevant documents. We also tried to re-ranking documents based on the initial retrieval before passage retrieval. Passages are retrieved based on the concepts defining in topics and concept coverage. Results of submitted runs are listed and discussed.

DIMACS at the TREC 2005 Genomics Track

This report describes DIMACS work on the text categorization task of the TREC 2005 Genomics track. Our approach to this task was similar to the triage subtask studied in the TREC 2004 Genomics track. We applied Bayesian logistic regression and achieved good effectiveness on all categories. 1. TEXT CATEGORIZATION TASK The Mouse Genome Informatics (MGI) project of the Jackson Laboratory provides ...

Symbol-Based Query Expansion Experiments at TREC 2005 Genomics Track

This paper illustrates the activity conducted at the TREC 2005 evaluation campaign in the ad-hoc task of the Genomics track. The retrieval effectiveness of a relevance feedback query expansion algorithm, which is based on symbols, is studied. The experimental results suggest that query expansion based on implicit relevance feedback is not always an effective means for improving effectiveness in...

TREC 2005 Genomics Track Experiments at IBM Watson

This paper describes our experiments in the TREC 2005 Genomics Track. For the ad-hoc retrieval task, we study synonym-based query expansion, as well as the effectiveness of a new pseudo-relevance feedback method which is derived from our recent work on semi-supervised learning. For the categorization task, we study various methods for estimating conditional class probability and determining the...
