Outline of Final Research Achievements

Speech-oriented information guidance systems have put into practice. Many of them introduce an example-based response generation technique. However,improvement of response accuracy and variety of response text expression are expected for a more useful interface. In this study, we propose machine learning approach to response selection and statistical machine translation approach to produce variation of response expression.
The proposed machine learning classifier which introduces two-stage classification using outputs of first stage classifiers, SVM, pboost etc. overcomes a conventional example-based method. On the other hand, it remains precise analysis to translate/convert a question to an answer because of difficulty of association between question and a answer.
In addition, we developed a prototype of a chat robot for upcoming demand on a personal spoken dialogue system.
