The Ephyra QA system has been developed as a flexibleopen-domain QA framework. This framework allows usto combine several techniques for question analysis andanswer extraction and to incorporate multiple knowledgebases to best fit the requirements of the TREC QAtrack, in which we participated this year for the firsttime. The techniques used include pattern learning andmatching, answer type analysis and redundancy eliminationthrough filters. In this paper, we give an overviewof the Ephyra system as used within TREC 2006 andanalyze the system's performance in the QA track.
