            Abstract : 
In this paper, we propose a method that extracts positive comments (e.g. (motto hyouka sarerubeki: should be valued)") and negative comments (e.g. (hetakuso: dub)") from Nico Nico Douga automatically. For example, positive comments extracted by our method are beneficial for analysis of campaign broadcast.
