Passage retrieval in a question answering system.

Pyykkö, Juri; Weegar, Rebecka and Nugues, Pierre LU (2014) The Fifth Swedish Language Technology Conference (SLTC 2014)
Abstract
In this paper, we describe a passage retrieval component for a questioning answering system and we evaluate its performance on

Swedish documents. We used a corpus of questions and answers transcribed from the Swedish board game Kvitt eller dubbelt

and, as source for the passages, we used the articles of the Swedish version of Wikipedia. We show that Wikipedia is a suitable

knowledge source to answer the game questions. For answers consisting of one word, we could extract passages of text that

contained the right answer for 91% of the questions and when these answers corresponded to an entity, we found and ranked

correct answers for up to 75% of the questions.
