Question and Answering System based on Predicate-Argument Matching.
Daisuke Kawahara, Nobuhiro Kaji, Sadao Kurohashi · 2002
This paper presents a Question and Answering system based on predicate-argument matching. Predicate-argument structures are utilized to capture more semantics in questions than a set of keywords. In addition to the predicate-argument matching, relation type matching is also used to handle expressions which are not mediated by verbs.
