Implementing a Japanese Semantic Parser Based on Glue Approach

摘要

This paper describes the implementation of a Japanese semantic parser based on glue approach. The parser is designed as domain-independent, and produces fully scoped higher-order in-tensional logical expressions, coping with semantically ambiguous sentences without storage mechanism. It is constructed from an English semantic parser on top of Lexical-Functional Grammar (LFG), and it attains broad coverage through relatively little construction effort, thanks to the parallelism of the LFG grammars. I outline the parser, and I present the analyses of Japanese idiosyncratic expressions including floated numerical quantifiers, showing the distinct readings of distributive and cumulative, as well as a double-subject construction and focus particles. I also explain the analyses of expressions that are syntactically parallel but semantically distinct, such as relative tense in subordinate clauses.
