Abstract

fetched live from OpenAlex

In the digital era, social media platforms have become central to communication across various domains. However, the vast spread of unregulated content often leads to the prevalence of hate speech and toxicity. Existing methods to detect this toxicity struggle with context sensitivity, accommodating diverse dialects, and adapting to varied communication styles. To tackle these challenges, we introduce an ensemble classifier that leverages the strengths of language models and traditional deep neural network architectures for more effective hate speech detection on social media. Our evaluations show that this hybrid approach outperforms individual models and exhibits robustness against adversarial attacks. Future efforts will aim to enhance the model’s architecture to further boost its efficiency and extend its capability to recognize hate speech across an even wider range of languages and dialects. • H armonyNet is a ensemble model that can detect hate speech. • H armonyNet is robust and can handle perturbations in texts. • H armonyNet shows better performance compared to individual models.

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.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
