Computational Semantics and Evaluation Benchmark for Interrogative
  Sentences via Combinatory Categorial Grammar
Hayate Funakura Koji Mineshima
We present a compositional semantics for various types of polar questions and
wh-questions within the framework of Combinatory Categorial Grammar (CCG). To
assess the explanatory power of our proposed analysis, we introduce a
question-answering dataset QSEM specifically designed to evaluate the semantics
of interrogative sentences. We implement our analysis using existing CCG
parsers and conduct evaluations using the dataset. Through the evaluation, we
have obtained annotated data with CCG trees and semantic representations for
about half of the samples included in QSEM. Furthermore, we discuss the
discrepancy between the theoretical capacity of CCG and the capabilities of
existing CCG parsers.
