Vocabulary Cross-Contamination between video game contents and disaster related posts on social media

The purpose of this study is to investigate the contamination of information collection via X(Twitter) during disasters by entertainment content, and to elucidate methods to prevent its impact. During disasters, local governments sometimes use Twitter to grasp the damage and rescue requests. However, there are concerns that the large volume of entertainment-related information posted on Twitter, even during disasters, can hinder disaster information collection. While posts related to entertainment contribute to the activation of their content and community, under the special circumstances of a disaster, they can obstruct the collection of disaster information by local governments. We define this state as contamination by entertainment content and aim to separate it. As a preliminary step, this paper analyzes twitter posts related to entertainment content during disaster and examines two points: 1) which types of content are easily contaminated, and 2) whether they can be separated.
