Dealing with Annotator Disagreement in Hate Speech Classification

arXiv:2502.08266v3 Announce Type: replace-cross Abstract: Hate speech detection is a crucial task, especially on social media where harmful content can spread quickly. Collecting social media content (tweets etc.) to train machine learning models is easy, but detecting and categorizing hate speech can be difficult due to the inherently subjective nature. This subjectivity leads to frequent disagreement among annotators, particularly for subtle or borderline content. Traditional approaches either discard non-consensus samples or force a ''gold standard'' through expert adjudication, ignoring va

Why this matters
Why now

The proliferation of social media platforms and the increasing reliance on AI for content moderation make robust hate speech classification a pressing need.

Why it’s important

Improving hate speech detection directly impacts online safety, platform governance, and the ethical deployment of AI in sensitive social contexts.

What changes

This research highlights the inherent subjectivity in hate speech annotation and proposes methods to explicitly model annotator disagreement, moving beyond simplistic 'gold standard' approaches.

Winners
  • · Social media platforms
  • · AI ethics researchers
  • · Trust and Safety teams
Losers
  • · Content creators using subtle hate speech
  • · Traditional fixed-label classification models
Second-order effects
Direct

More nuanced and effective hate speech detection models are developed and deployed across platforms.

Second

Social media content moderation policies evolve to integrate and reflect the complexities of annotator disagreement, leading to fairer and more consistent application.

Third

Enhanced understanding of hate speech subjectivity informs broader discussions on online discourse, free speech, and the role of AI in shaping public opinion.
