| Outline of Final Research Achievements |
Linguistic Atlas of Japan (LAJ), whose survey was conducted from 1957 to 1965, is one of the basic research materials capturing the geographical distribution of Japanese dialects in 2400 localities. While nationwide quantitative studies have been conducted on LAJ, most of them used calculations based on the 47-prefecture-unit. We have been developing LAJDB (Linguistic Atlas of Japan Database) to enable us to use the data of 2400 localities on computers. The nationwide "high resolution" patterns of 2400 localities is approximately 51 times the resolution of 47 prefectures. In this study, in order to explore the potential of large scale LAJ data in advancing the quantitative approaches, we prepared the data incorporating important extra-linguistic factors, such as historical road network and time series population distribution, and made some preliminary quantitative observations of LAJ data by utilizing the extra-linguistic factors.
