Exploiting paraphrases in a question answering system


Rinaldi, F; Dowdall, J; Kaljurand, K; Hess, M; Mollà Aliod, D (2003). Exploiting paraphrases in a question answering system. In: ACL-2003, Second International Workshop on Paraphrasing: Paraphrase Acquisition and Applications, Sapporo, Japan, July 2003 - July 2003, 25-32.

Abstract

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.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
