Classification Methods for Hate Speech Diffusion: Detecting theSpread of Hate Speech on Twitter
Bibliographic record
Abstract
In this paper, we investigate predictive models to detect the spread of hate speech on Twitter based on diffusion patterns. We experiment with a dataset of 10,000 tweets manually labelled as hate speech or not and show that classification based solely on the sharing graph yields strong F1 scores for our task and high hate speech detection precision. We also highlight the vulnerability of existing textual hate speech detection methods to adversarial attacks and demonstrate that while our methods do not outperform stateof-the-art text models, graph-based models provide robust detection mechanisms and are able to detect instances of hate speech that missed by text classifiers. We find that graph convolutional networks produce the strongest hate speech F1 score of 0.58 and that kernel methods offer strong predictive potential. Finally, we also consider the effects of automated bots in the diffusion of hate speech content and conclude that their sharing behavior plays an insignificant role in our experiments.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
