◆Research Interests
Grammar acquisition, grammar change and evolution
Why we human beings could acquire context-free grammar? Via computer simulation, we try to explain such hypotheses as efficient ambiguity resolution or innate language acquiring device.
Logic of Knowledge, Belief, Time and Negation
Knowledg and belief (uncertain knowledge) are represented by modal logic, as well as temporal logic. Considering those required axioms for each modal operator, we formalize the appropriate results of belief revision or agent communication. In addition to formal semantics of natural language, we apply the idea to the legal reasoining and the inspection of code soundness.
Grammatical analysis of music
A piece of music has a tree structure which includes long distance dependency. We apply the Generative Theory of Tonal Music and other linguistic knowledge, and analyze the stable structure of music scores.
