| Abstract(in English) | In recent years, the spread of the Internet has created an environment where users can speak out on online platforms, and the number of users is increasing. Therefore, we focus on the concept of values in order to understand social trends. Values are sometimes used together with various concepts that describe a series of people's mental processes, and it is explained that they are based on "desires, demands, and motivations" that direct "attitudes" and lead to "words, deeds, and actions''. In this report, we focus on "attitudes" and aim to understand the trends in the spread of coronaviruses on Twitter. A classifier was constructed by learning linguistic information from Twitter using BERT to classify "attitudes" as "action" or "restricted action" in response to requests for self-restraint by the government and local authorities. As a result of verifying the accuracy of the classifier, we confirmed that it can classify attitudes as well as humans. |
