| Abstract(in English) | A probabilistic answer selection on spoken dialog system requires a lot of question-and-answer pair as a training data. However, it costs much to collect a sufficient amount of transcription of user's utterance, or to make the question database manually. In this paper, a sentence generation method based on word N-gram to build a question database of a spoken dialog system from given keywords. First, the best word sequences between the keywords are searched based on N-gram. Then, they are concatenated each other and rescored to get the final sentences to be used for the training data. The proposed method was experimented on a public speech-oriented information guidance system. It has been shown that the conventional method with only keywords could get the correct response rate of 59.6%, whereas the proposed method which uses the generated sentences as training data got 65.1%, when using recognized text. Experiments on task-independent N-gram(Web / Newspaper model)also showed that the proposed method can achieve higher accuracy than the conventional method. Comparisons of various parameters were also investigated. |
