Exploiting paraphrases in a Question Answering system
Fabio Rinaldi, James Dowdall, Kaarel Kaljurand, Michael Heß, Diego Mollá · 2003
We present a Question Answering system for technical domains which makes an intelligent use of paraphrases to increase the likelihood of finding the answer to the user's question. The system implements a simple and efficient logic representation of questions and answers that maps paraphrases to the same underlying semantic representation. Further, paraphrases of technical terminology are dealt with by a separate process that detects surface variants.
