Abstract (in Japanese) (See Japanese page) 
(in English) Recently, a use of e-Learning system increases on Internet and Intranet.
In particular, VOD learning systems with slides and videos have been
used for self-learning and lectures.
Therefore, for foreign students who are non-native Japanese language, we consider that understanding
of topics is difficult only by slides and sounds.
In this study, we propose emphasis of important words and sentence contraction of subtitles in the VOD learning system.
In particular, for calculation of important words, we use
the documentary section of TF-IDF as the place around the subtitles,
we evaluated the number of words that it should emphasize.
On the other hand, we analyze dependency relation and evaluate every phrase by TF-IDF for sentence contraction, and we delete the low phrase of the evaluate value. In addition, we propose methods to delete a case structure with low TF-IDF value using the sentence division from the surface word and case structure to compound sentences and complex sentences.
