Selecting answers with structured lexical expansion and discourse relations

Résumé

n this paper, we present the LIMSI’s participation to QA4MRE2013. We decided to test two kinds of methods. The first one focuses on complex questions, such as causal questions, and exploits discourse relations. Relation recognition shows promising results, however it has to be improved to have an impact on answer selection. The second method is based on semantic variations. We explored the English Wiktionary to find reformulations of words in the definitions, and used these reformulations to index the documents and select passages in the Entrance exams task.
