DCU at FIRE 2013: cross-language !ndian news story search (2013)

Abstract We present an overview of our work carried out for DCU’s participation in the Cross Language !ndian News Story Search (CL!NSS) task at FIRE 2013. Our team submitted 3 main runs and 2 additional runs for this task. Our approach consisted of 2 steps: (1) the Lucene search engine was used with varied input query formulations using different features and heuristics designed to identify as many relevant documents as possible to improve recall; (2) document list merging and re-ranking was performed with the incorporation of a date feature. The results of our best run were ranked first among official submissions based on NDCG@5 and NDCG@10 values and second for NDCG@1 values. For the 25 test queries the results of our best main run were NDCG@1 0.7400, NDCG@5 0.6809 and NDCG@10 0.7268.
