Executive Summary

In this paper, the authors describe the system they used for the CLEF 2008 monolingual Dutch and multilingual English-to-Dutch question answering task. Their QA-system, Joost, is largely the same as used in for previous participations in CLEF. Joost is an open-domain QA-system for Dutch, which makes heavy use of syntactic information in all of its components. The text collections used for CLEF (Dutch newspaper text and Wikipedia) are parsed using the Alpino parser (van Noord, 2006), which performs part-of-speech and named entity tagging, and syntactic analysis using dependency relations.
