Knowledge Acquisition about Event Information from Twitter
Kohei Yamamoto, Kazutaka Shimada (Kyutech) NLC2018-38
Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we propose a knowledge acquisition method for non-task-oriented dialogue systems, Such dialogue systems need a wide variety of knowledge for generating appropriate and sophisticated responses. However, constructing such knowledge is costly. To solve this problem, we focus on a relation about each tweet and the posted time. First, we extract event words, such as verbs, from tweets. Then, we generate frequency distribution for five different time divisions, e.g., a monthly basis. We checked high ranked event words in each time division. As a result, we obtained not only common-sence things such as "sleep" in night but also interesting events such as "challenge" in April (April is the starting month in Japan.) .
