(a) Proportion of comments for each topic by platform. The cell color intensity corresponds to the proportion of comments discussing a given topic; a higher percentage results in a darker hue. (b) Box plots distributions of the sentiment tone across topics. On the x-axis, sentiment tones are represented as values. A negative value indicates a negative sentiment, while a positive value suggests the opposite. The further away from zero the value is, the stronger the sentiment. The vertical red dashed line at the 0 mark, differentiates positive tones from negative tones. Black diamonds inside the boxes indicate the average sentiment tone for each topic.
