通过分层建模用户身份,提升对被群体重用的侮辱性词汇的识别准确率。

AIWizards at MULTIPRIDE: A Hierarchical Approach to Slur Reclamation Detection

  • 先用弱监督大模型推测用户是否属于LGBTQ+群体,生成模糊标签。
  • 再用这些标签训练BERT类模型,学习与身份相关的语言特征。
  • 融合身份特征与仇恨言论模型,显著提升对重用词汇的检测效果。

识别被群体重用的侮辱性词汇是仇恨言论检测中的核心挑战,因同一词汇在不同社会身份和语境下可能为攻击性表达或内部认同。本文针对EVALITA 2026多语言仇恨言论任务(MultiPRIDE)中的子任务B,提出一种分层方法建模辱骂词重用过程。核心假设为LGBTQ+成员更可能以宣告式方式使用特定贬义词。方法分为两阶段:第一阶段基于弱监督大语言模型,结合推文与用户简介,为用户分配模糊标签以推断其归属LGBTQ+的可能性;第二阶段利用该软标签训练一个类似BERT的模型,学习与性别/性取向身份相关的潜在表征,并将其与新初始化的仇恨言论检测模型融合。在意大利语和西班牙语数据集上的实验表明,本方法性能与强基线模型相当,同时提供模块化、可扩展的框架,用于整合社会语言学上下文。研究认为,对用户身份与话语语境进行更精细的分层建模,有望进一步提升重用语言的检测能力。代码已开源:https://github.com/LucaTedeschini/multipride。

原文摘要 · Abstract (English)

Detecting reclaimed slurs represents a fundamental challenge for hate speech detection systems, as the same lexcal items can function either as abusive expressions or as in-group affirmations depending on social identity and context. In this work, we address Subtask B of the MultiPRIDE shared task at EVALITA 2026 by proposing a hierarchical approach to modeling the slur reclamation process. Our core assumption is that members of the LGBTQ+ community are more likely, on average, to employ certain slurs in a eclamatory manner. Based on this hypothesis, we decompose the task into two stages. First, using a weakly supervised LLM-based annotation, we assign fuzzy labels to users indicating the likelihood of belonging to the LGBTQ+ community, inferred from the tweet and the user bio. These soft labels are then used to train a BERT-like model to predict community membership, encouraging the model to learn latent representations associated with LGBTQ+ identity. In the second stage, we integrate this latent space with a newly initialized model for the downstream slur reclamation detection task. The intuition is that the first model encodes user-oriented sociolinguistic signals, which are then fused with representations learned by a model pretrained for hate speech detection. Experimental results on Italian and Spanish show that our approach achieves performance statistically comparable to a strong BERT-based baseline, while providing a modular and extensible framework for incorporating sociolinguistic context into hate speech modeling. We argue that more fine-grained hierarchical modeling of user identity and discourse context may further improve the detection of reclaimed language. We release our code at https://github.com/LucaTedeschini/multipride.
