Contrastive Linguistic Database for Japanese Language Learners' Written Language (Taiyaku Sakubun DB)
This corpus forms a database of essays written by learners of Japanese as a Second Language (JSL). The data include Japanese essays written by about 1,600 learners from 21 countries, as well as translations of the essays made by the learners in their first languages, and corrections of the Japanese essays made by Japanese language teachers. The database serves as a useful resource for research in such fields as contrastive linguistic studies and JSL pedagogy.
The corpus is available on the internet. (http://www2.kokken.go.jp/eag/. User registration is required.) Shown below is a screenshot of a data-selecting window. An essay written by a French learner is shown in the bottom-left window, while the translation into French is shown in the bottom-right window.
