When we proposed the project, at that time, the number of logs of the Japanese e-Learning system JPLANG was 5.3 million and now it exceeded 18.3 million and its registered user exceeded 20,000.We have developed a learning mining system based on large scale log data statistical processing algorithms.We also developed Web conversational laboratory for completing web based five skill training required for CEFR. For the future teaching materials development, we have further developed 70 million words of Japanese textbook corpus.
