a shows period from 2010-2014, using the topic “Google’s exit from the Chinese market” as an example. b shows period from 2015-2019, While c shows period from 2020-2024. The same color represents topics belonging to the same category within the ten topics of China-related discourse. The x-axis in the figure represents the timeline, with the proximity of topic bubbles indicating the degree of semantic relatedness between topics. The size of the bubble represents the number of topics. The bigger the bubble representing a topic is distributed in the graph, the larger its relative quantity. Note that this graph is a schematic, and the time and quantity do not represent precise values.
