| Research Abstract |
Since many VOD lectures in the past were only materials displayed with visual images and in PowerPoint, it was difficult for foreign students to use them as they were. In the development of a VOD lecture learning system that matches the Japanese comprehension levels of foreign students, besides adding subtitles and providing simple subtitles, we developed a Chinese search function and a search function for self-learning topics. Furthermore, we assessed the difficulty of Japanese words with unclear levels of difficulty and carried out data acquisition from dictionaries and the Web; by improving the machine learning technique, we developed a system that evaluates the level of difficulty of the actual VOD lecture from the level of difficulty of the words used.
