| Abstract(in English) | In the closed captions, there are a lot of typical expressions to express specific things, for example, first introduction of a guest in a talk show or explanation of a place in travel program. Such information helps us to put metadata to the corresponding scenes. This paper proposes a method to extract a section including typical expressions. The first step generates tree structures from inputted section of sentences and evaluates the similarities between those tree structures. We use these similarities as weak learners of adaboost algorism to judge whether the section of sentences includes typical expressions or not. In the experiment of detecting sections including typical expressions which explain a place with video targeting closed captions of TV programs concerned with travel, we show the effectiveness of our method. |
