Abstract
We describe our system for the monolingual Dutch and multilingual English to Dutch QA tasks. We describe the preprocessing of Wikipedia, inclusion of query expansion in IR, anaphora resolution in follow-up questions, and a question classification module for the multilingual task. Our best runs achieved 25.5% accuracy for the Dutch monolingual task, and 13.5% accuracy for the multilingual task.
This research was carried out as part of the research program for Interactive Multimedia Information Extraction, imix, financed by nwo, the Dutch Organisation for Scientific Research.
