Douglas W. Oard, Jian‐qiang Wang, Dekang Lin, Ian M. Soboroff · 2000
The University of Maryland team participated in four aspects of TREC-8: the ad hoc retrieval task, the main task in the cross-language retrieval (CLIR) track, the question answering track, and the routing task in the filtering track. The CLIR method was based on Pirkola's method for Dictionary-based Query Translation, using freely available dictionaries. Broad-coverage parsing and rule-based matching was used for question answering. Routing was performed using Latent Semantic Indexing in profile space. This working notes paper presents preliminary results. 1 Introduction The Eighth Text REtrieval Conference (TREC-8) offered many more attractive evaluation opportunities that our team could have pursued, so we chose to participate in four aspects of the work that are aligned particularly closely with our ongoing work. In Cross-Language Information Retrieval track (CLIR), we focused on rapid retargetability, seeking to learn how well we could do with freely available resources that...
