Using the methodology of data analysis and computational science, this course aims to solve theoretical and empirical problems that were not fully explained by previous research and to develop new ways of doing linguistic research. In particular, novelty and advancement of our linguistic investigation are found in the discovery and theorization of new linguistic facts through processing a large amount of linguistic data.
Theoretical Linguistics, Linguistic Typology
Analyses of the interface between syntax and morphology, explication of linguistic change in time and space
I specialize in the comparative research and theory construction in Asian languages, as well as the mechanism of linguistic change through language contact. I teach students how to analyze linguistic data with a linguistic method and put the results together in a verifiable way, and provide them with the practical skill of linguistic data analyses using the inductive or deductive method.
English linguistics, corpus linguistics
Research on the methodology of linguistic description and study of Japanese and English usages
I deal with linguistic descriptions and usages in various linguistic phenomena in English and Japanese. I encourage students to utilize various corpora and seek for the best method of analysis for a variety of linguistic phenomena, and teach them the methodology of linguistic analyses for solving their respective research questions in linguistics.
Linguistic Theory, Syntax
Descriptive, theoretical, and experimental syntax of natural language
I work on the development of a theoretical model explaining various syntactic phenomena in natural language. Furthermore, I examine the validity of the theoretical model by experimentally testing the hypothesis about linguistic competence and performance.
Modelling of the Japanese grammatical and semantic resources applicable to large corpus analyses
I am engaged in the study and description of Japanese language both in written and spoken forms. I am trying to work out a computational model of grammatical and semantic resources applicable to analyze large corpus, which allows us to improve information retrieval and conversational agent systems.
Linguistics, Phonetics and Phonology
Experimental and corpus-based research on the sounds of language
My research interest lies in phonetics and phonology, which are subfields of linguistics. I address issues such as how speech sounds are produced and perceived, what acoustic properties they have, whether there are regular patterns in their alternations, and whether speakers are psychologically aware of such patterns. I often use corpus-based and experimental approaches.
