Reasoning over Dependency Relations for QA
Gosse Bouma, Jori Mur, Gertjan van Noord, RIJKSUNIVERSITEIT GRONINGEN · 2005
We present a QA system in which question analysis, off-line answer extraction and reranking and identification of potential answers from an IR all make use of syntactic dependency relations. We show that the addition of equivalence rules over patterns of dependency relations, which capture cases where different syntactic patterns express the same semantic relationship, improves the performance of various modules of the system.
