Mapping Japan’s China-related twitter discourse (2010–2024) using BERTopic
Fig 8
Stacked charts of topic-sentiment evolution (2010-2024).
This figure consists of ten subplots, each representing a distinct topic. The ten subplots are divided into two groups: the five on the left represent topics in the domain of high politics, while the five on the right correspond to topics in the domain of low politics. Among the latter, the first three pertain to culture and education, and the final two relate to economics and technology. In each subplot, the horizontal axis denotes time, while the vertical axis displays the stacked area segmented into five colors. Each color corresponds to the proportion of tweets expressing one of five sentiment categories—very negative, negative, neutral, positive, and very positive—relative to the total number of tweets within that topic.
