Parsing Gapping Constructions Based on Grammatical and Semantic Roles

Yoshihide Kato, Shigeki Matsubara


Abstract
A gapping construction consists of a coordinated structure where redundant elements are elided from all but one conjuncts. This paper proposes a method of parsing sentences with gapping to recover elided elements. The proposed method is based on constituent trees annotated with grammatical and semantic roles that are useful for identifying elided elements. Our method outperforms the previous method in terms of F-measure and recall.
