Replication Data for: Online Propagation of Emotions: A Study of Resharing Dynamics on Social Media Following Celebrity Suicides

This dataset accompanies the study “Online Propagation of Emotions: A Study of Resharing Dynamics on Social Media Following Celebrity Suicides” published in PLOS ONE. It contains data from 91,868 resharing cascades on X (formerly Twitter) that occurred in response to four celebrity suicide events. The dataset includes variables capturing propagation dynamics (cascade size, lifetime, median inter-retweet delay, and time to the fifth retweet), content attributes (word count, presence of hashtags), original author characteristics, and probabilistic emotion scores (anger, sadness, fear, surprise, disgust, joy, and neutral), derived using a fine-tuned DistilRoBERTa language model.
