Communication via comments is carried out actively in video sharing sites. Recently several studies on analysis of communication through comments and collaborative creative activities are conducted. When it becomes possible to analyze comments, these studies become possible to acquire useful information on user's behavior, involvement of users and video works. The interest of the user, an opinion, and the reaction to other users influence on comments. Moreover, the expression refelecting Web's original culture make noise removal difficult and the object to mention does not exist. Thus, useful information is hard to obtain in each study. Moreover, accurate analysis of the expression is difficult, due to unique expressions that appear in comments. In this paper, we created a dictionary where unique expressions that appear in a video sharing site are registered in the dictionary, and propose an analysis method of these comments using the dictionary.
