摘要:

分析种族或宗教偏见对于提高自然语言处理模型的公平性、问责制和透明度非常重要。然而,许多技术依赖于人工编译的偏见术语列表,这是昂贵的创建和覆盖范围有限。在这项研究中,我们提出了一个完全数据驱动的管道,用于生成文化知识和刻板印象的知识图谱(KG)。我们由此产生的幼儿园涵盖5个宗教团体和5个民族,并可以很容易地扩展到包括更多的实体。我们的人工评估显示,大多数(59.2%)非单例条目是连贯和完整的刻板印象。我们进一步表明,在言语化KG上执行中间掩蔽语言模型训练会导致模型中更高水平的文化意识,并有可能提高相关任务中知识关键样本的分类性能,即,仇恨言论检测

英文摘要:

Analyzing ethnic or religious bias is important for improving fairness, accountability, and transparency of natural language processing models. However, many techniques rely on human-compiled lists of bias terms, which are expensive to create and are limited in coverage. In this study, we present a fully data-driven pipeline for generating a knowledge graph (KG) of cultural knowledge and stereotypes. Our resulting KG covers 5 religious groups and 5 nationalities and can easily be extended to include more entities. Our human evaluation shows that the majority (59.2%) of non-singleton entries are coherent and complete stereotypes. We further show that performing intermediate masked language model training on the verbalized KG leads to a higher level of cultural awareness in the model and has the potential to increase classification performance on knowledge-crucial samples on a related task, i.e., hate speech detection.
