DIA-HARM: Dialectal Disparities in Harmful Content Detection Across 50 English Dialects

Wed, 08 Apr 2026 00:00:00 +0000

🏆 Social Impact Paper Award — ACL 2026, San Diego, July 2–7, 2026.

DIA-HARM investigates the robustness of harmful content detection systems across 50 English dialects, addressing critical equity gaps in automated content moderation.

Key contributions include:

Dialect-Diverse Detection (D3) Corpus: Over 195K samples derived from benchmark harmful content datasets, transformed using 189 morphosyntactic rules from eWAVE covering 50 dialects
Comprehensive Model Evaluation: 16 detection models tested — 10 fine-tuned, 5 zero-shot, and 1 in-context learning — revealing systematic performance disparities across dialect groups
D-PURIFY Validation: Quality filtering pipeline ensuring linguistic validity of dialect transformations with 97.2% average F1 for the best model (mDeBERTa)
Key Finding: Detection degradation correlates with density of morphosyntactic transformations rather than specific dialect features, with 2,450 dialect pairs analyzed

BLUFF: Benchmarking in Low-resoUrce Languages for detecting Falsehoods and Fake news

Sun, 01 Feb 2026 00:00:00 +0000

BLUFF is the largest multilingual fake news detection benchmark to date, spanning 79 languages (20 high-resource “big-head” + 59 low-resource “long-tail”) with over 202,000 samples. The benchmark combines human-written fact-checked content from 130 IFCN-certified organizations with LLM-generated content from 19 diverse models.

Key contributions include:

AXL-CoI (Adversarial Cross-Lingual Agentic Chain-of-Interactions): A multi-agentic framework using 10 fake chains and 8 real chains for controlled multilingual content generation
mPURIFY: A 4-stage quality filtering pipeline with 32 features across 5 dimensions, ensuring dataset integrity through asymmetric evaluation thresholds
Bidirectional translation: English↔X coverage across 70+ languages with 4 prompt variants
Comprehensive evaluation: State-of-the-art detectors suffer up to 25.3% Macro-F1 degradation on low-resource versus high-resource languages
