Domain Specific Retrieval: Back to Basics

摘要

In this paper describe Berkeley's approach to the Domain Specific (DS) track for CLEF 2006. This year we did not use the tools for thesaurus-based query expansion and de-compounding for German used in previous years. This year Berkeley submitted 12 runs, including one for each subtask of the DS track. These include 3 Monolingual runs for English, German, and Russian, 7 Bilingual runs (3 X2EN, 1 X2DE, and 3 X2RU), and 2 Multilingual runs. For many DS sub-tasks our runs were the best performing runs, but sadly they were also the only runs for a number of sub-tasks. In the sub-tasks where there were other entries, our relative performance was above the mean performance in 2 sub-tasks and just below the mean in another.
