Abstract
A new type of interactive interface is developed for e-learning system of disaster mitigation activities. The system can understand natural language communication by use of the knowledge base on earthquake disaster mitigation. The originally developed knowledge base is implementing knowledge structure and scenario flow, and is able to navigate e-learning system. By use of this interface, smooth and arranged access for the large amount of web contents is developed, and it is effective for every user for their easy comprehension about the importance of disaster mitigation.
