区分仇恨言论与重新夺回的用语,提升社交媒体内容审核准确性。
Challenger at MultiPRIDE: Is It Hate Speech or Reclaimed?

- 用密集语义嵌入结合噪声过滤和MLP分类器,方法简单可解释。
- 在极端类别不平衡数据下仍保持高F1分数,表现稳健。
- 适合资源有限但需高可解释性的实际部署场景。
仇恨言论在现代数字环境中日益有害,尤其在社交平台中。尽管自动检测技术取得进展,但仍面临关键挑战:区分真正的仇恨言论与被重新夺回的语言表达。准确标注困难源于这类表达的细微语境依赖性。本文为MultiPride共享任务提出一种简洁且可解释的方法,通过生成密集语义文本嵌入,结合Cleanlab进行标签噪声过滤,并采用逻辑回归与多层感知机(MLP)进行最终分类。系统设计注重在有限计算资源下保持强性能。我们使用精确率、召回率和F1分数(含宏平均)评估,实验结果表明,在极端类别不平衡数据集上仍具稳健表现。研究显示,未来通过更大嵌入模型和更先进预处理技术有望进一步提升性能,同时维持可解释性。
原文摘要 · Abstract (English)
The spread of hate speech has become increasingly harmful in modern digital environments, particularly on social networking platforms. While recent advances have shown promising results in automatic hate speech detection, a key challenge remains: distinguishing genuine hate speech from reclaimed language. Accurate labeling is difficult due to the nuanced and context-dependent nature of reclaimed expressions. In this paper, we present a simple and interpretable approach for distinguishing hate speech from reclaimed language, developed for the MultiPride Shared Task. Our method generates dense semantic text embeddings and incorporates a label-noise filtering stage using Cleanlab with logistic regression, followed by a Multi-layer Perceptron (MLP) neural network for final classification. The system is designed to operate under limited computational resources while maintaining strong performance. We evaluate our approach using precision, recall, and F1-score, including macro-averaged metrics. Experimental results demonstrate robust performance despite extreme class imbalance in the dataset. Overall, the findings highlight the potential for further improvements through larger embedding models and more advanced preprocessing techniques while preserving interpretability.
