Dictlinker is an interactive computer system for assisting students to read and understand Japanese sentences. The system displays the translation of each word on the computer screen. The system is presently used for teaching Japanese at MIT. A survey was held among the teachers and the students regarding the effectiveness of the proposed system. The survey result indicates that it is necessary for the intermediate and advanced course students to refer the dictionary for understanding the meaning of difficult Kanji. Therefore, it is largely hoped that the proposed system would be an effective and powerful tool for the advanced course students.
