| Abstract(in English) | It is difficult to discriminate a request to a system from a chat based on only simple keywords, because keywords are sometime included in utterances of explaining an usage of a system, or appear by misrecognition in chats. On another front, it has troubles to use network grammar, bacause it makes the usage difficult for people unaccustomed to a system due to fixed expressions of system request. In this paper, we propose a discrimination method based on AdaBoost using linguistic information obtained from speech recognition. To solve a problem of misrecognition, a confution network is employed. The confusion network permits deep hypothesises of speech recognition. The experimental results showed that 95.7% of precision and 89.8% of recall on a task which is recognized with 42.1% of word accuracy. |
