AnswerFinder at TREC 2006

This article describes the AnswerFinder question answering system and its participation in the TREC 2006 question answering competition. This year there have been several improvements in the AnswerFinder system, although most of them in the implementation sphere. The actual functionality used this year is almost exactly the same as last year, but many bugs are fixed and the efficiency of the system has improved much. This allows for more extensive parameter tuning. Here we will also present an error analysis of the current AnswerFinder system.
