Answer Extraction Using a Dependency Grammar in ExtrAns

by: Diego Mollá, Gerold Schneider, Rolf Schwitter, and Michael Hess

In: Traitement Automatique des Langues, Vol. 41, Nr. 1 (2000) , p. 127-156.

Abstract

We report on the implementation of an answer extraction system, ExtrAns, that uses the output of a dependency-based parser and grammar. In order to increase speed, the parser and grammar used sacrifice functionalism in the framework of dependency theory in favour of projectivity. We have found that the resulting dependency structures, although cumbersome to handle, can be used by ExtrAns to find the syntactic and semantic dependencies needed in several of the linguistic processing stages. In particular, we focus on the minimal logical form generation.
