A question-and-answer style spoken dialog system based on example-based answer generation is known to be robust against variation of user utterances. However, it is costly to create QA database for a new task. In this paper, we proposed a method to reduce cost of preparing the database by generating the database automatically from templates. As a result, we obtained almost same performance using the automatically generated QA database compared with the manually prepared database. In addition, we propose a new scoring method to choose an answer based on F-measure,which improved the accuracy of answer selection. |
