Who Let the Dogs Out? Auditing Dogwhistle Coverage in Hate Speech Benchmarks Across Target Groups

Reva Hirave, Ryan Oet


Abstract
Automated hate speech detection relies on benchmark datasets for both training and evaluation, making benchmark composition a fairness concern that precedes classifier behavior. We audit dogwhistle coverage in two widely-used benchmarks (HateXplain and Measuring Hate Speech) using an existing glossary of 340 dogwhistle entries mapped onto a four-level coding sophistication taxonomy, ranging from explicit slurs (L1) to opaque persona signals (L4). Across 59.6k posts in the benchmark union, annotation failure is the dominant failure mode: at the stereotype-based level (L2), every racial and religious group with stable match counts is labeled non-hateful at rates exceeding 60%. Collection failure, where entire dogwhistle categories are absent from the union, becomes co-dominant at higher coding levels, with twenty group x level cells showing categorical gaps that re-annotation cannot fix. These failures are unevenly distributed: race:black vs. race:middle_eastern fails the 4/5 rule on annotation DI at L2 (DI=0.661), and lgbtq:Trans/NB posts one of the highest annotator failure rates (81.2%, second only to origin:undocumented) and the lowest presence rate of any comparably-sized group at every level. We distinguish collection failure from annotation failure as mechanisms with different remediation implications, and release our mapped glossary and pipeline publicly.
