Cognitive Linguistics & Quantitative Text Analysis Laboratory

We reveal the movement of the human mind with linguistic data.

Linguistics is the scientific study of language, encompassing the analysis of linguistic characteristics and the construction of linguistic models. Languages are dynamic systems that evolve over time and across communities. However, due to the inherent limitations of studying individual speakers, it is necessary to construct a representative corpus, a collection of language data, to gain insights into population-level trends. In our laboratory, we analyze this qualitatively and quantitatively by comparing words used in different eras and communities, or between different languages, or by comparing historical changes in the same language. To create corpora, we use programming and questionnaires. We then machine process them using our knowledge of natural language processing, and statistically analyze and quantify the resulting numerical values. However, since the analysis process necessitates the utilization of research outcomes from linguistics (e.g., categorization, modification, and connective relationships) and cognitive science (e.g., how individuals process language), our laboratory employs an analytical approach that integrates the humanities and sciences. Consequently, our laboratory is equipped to conduct research that can be approached from either a humanities or a science perspective.
