Abstract

The aim of this study is to establish a reliable criterion for rating the level of Japanese words, and to develop an automatic word level rating system based on the criterion. We have already developed word level rating systems based on the coverage for the Japanese language proficiency test (Kawamura, 1999), the word familiarity, and the word frequency (Kawamura, 2008), and released them on our web page (http://language.tiu.ac.jp/) as parts of Reading Tutor. In the present study, the inverse document frequency (IDF) calculated from a newspaper database is employed and evaluated.
