| Outline of Final Research Achievements |
The research presented in this paper aims at advancing text readability studies for Japanese and devises a practical and useful system that contributes to Japanese language teaching, learning, and research. More specifically, utilizing leveled corpora mainly consisting of text from textbooks of Japanese, we produced the following formula to measure the readability level of a given text in six scales: X = {mean length of sentence * -0.056} + {proportion of kango * -0.126} + {proportion of wago * -0.042} + {proportion of number of verbs among all words * -0.145} + {proportion of number of auxiliary verbs * -0.044} + 11.724 (R2=.896) . The formula was tested against another set of leveled text in Japanese to prove its reliability. Lastly, the method was implemented in a computer system that calculates and produces the estimated level of a text via a web-based online interface.
