Meaning representations from Japanese and English treebanks

Abstract

This paper describes an implemented system that directly obtains meaning representations of quality from treebank annotations. The central component is a system of evaluation for a small formal language with respect to a structured information state. Inputs to the system are expressions of the formal language obtained from the conversion of parsed treebank data. Outputs are Davidsonian (higher order) predicate logic meaning representations. Having a system of formal evaluation as the basis for generating meaning representations is shown to make possible accepting input with minimal conversion from existing treebanks and treebank parsers. Demonstrations of the system are given with Japanese and English data.
