Title A Derivational Rephrasing Experiment for Question Answering
Authors Bernard Jacquemin
Abstract In Knowledge Management, variations in information expressions have proven areal challenge. In particular, classical semantic relations (e.g. synonymy) donot connect words with different parts-of-speech. The method proposed tries toaddress this issue. It consists in building a derivational resource from amorphological derivation tool together with derivational guidelines from adictionary in order to store only correct derivatives. This resource, combinedwith a syntactic parser, a semantic disambiguator and some derivationalpatterns, helps to reformulate an original sentence while keeping the initialmeaning in a convincing manner This approach has been evaluated in threedifferent ways: the precision of the derivatives produced from a lemma; itsability to provide well-formed reformulations from an original sentence,preserving the initial meaning; its impact on the results coping with a realissue, \textit{ie} a question answering task . The evaluation of this approachthrough a question answering system shows the pros and cons of this system,while foreshadowing some interesting future developments.
