Abstract

fetched live from OpenAlex

One key for improving hate speech detection performance is to have a textual training corpus that is vast and confidently labeled. This paper develops a semi-supervised learning approach with self-training to benefit from the abundant amount of social media content and develop a robust hate speech classifier for future predictions. The classifier is self-trained iteratively using the most confident pseudo labels obtained from a large-scale unlabelled Twitter corpus. We demonstrate our approach’s efficacy and the high quality of the produced supervised hate speech dataset through experiments.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
