Abstract

The University of Amsterdam participated in the Question Answering (QA) Track of CLEF 2005 with two runs. In comparison with previous years, our focus this year was adding to our multi-stream architecture a new stream that uses offline XML annotation of the corpus. We describe the new work on our QA system, present the results of our official runs, and note areas for improvement based on an error analysis.
