This paper presents a bilingual question answering system that has Finnish as its source language and English as its target language. The system was evaluated in the QA@CLEF 2004 evaluation campaign. It is the only officially evaluated QA system that takes Finnish as input. The system is based on question classification and analysis, translation of important query terms, document retrieval, answer pattern instantiation and answer selection. The system achieves an accuracy of 10,88%.
