I study the meaning of natural language with formal tools developed in philosophical and mathematical logic. My concern is whether/how the semantic differences among natural languages, especially between Japanese and English, can be characterized with the formal apparatus. The current focus is disjunctions ("p or q", "p ka q", etc.) across languages. I also have an interest in linguistic realizations of inference patterns—the way thought processes like deduction and abduction -- are expressed within language. I occasionally work with my collaborator to study the development of logical knowledge/ability of AIs.
