Creating correct, semantic representa- tions of questions is essential for appli- cations that can use formal reasoning to answer them. However, even within a restricted domain, it is hard to anticipate all the possible ways that a question might be phrased, and engineer reliable processing modules to produce a correct semantic interpretation for the reasoner. In our work on posing questions to a bi- ology knowledge base, we address this brittleness in two ways: First, we exploit the DIRT paraphrase database to intro- duce alternative phrasings of a question; Second, we defer word sense and se- mantic role commitment until question answering. Resulting ambiguities are then resolved by interleaving additional interpretation with question-answering, allowing the combinatorics ...
