| Abstract(in English) | Dialogue systems have been increasingly important these days. In particular, non-task-oriented dialogue systems have been studied because of the success of neural network approaches such as seq2seq models. However, these models tend to generate simple responses such as "yes" and "ok." To construct a dialogue system that holds user's attention continuously, we need to generate utterances that capture the interest of the user. In this paper, we propose a method to extract trivia sentences for the purpose. Trivia information perhaps adds a surprise to users. Therefore, capturing trivia information is beneficial for dialogue systems. We estimate a trivia score of a sentence by using machine learning approaches. We obtained 0.81 on the $nDCG@10$ score by a ranking method. |
