网络仇恨言论和攻击性语言已被广泛认为是严重的社会问题。为了解决这个问题,最近出现了几项研究,重点关注使用机器学习方法检测和解释仇恨言论和攻击性语言。虽然这些方法在检测和解释仇恨言论和攻击性语言样本方面非常有效,但它们并没有探索这些样本的表示的影响。在这项工作中,我们引入了一种新颖的,基于发音的仇恨言论和攻击性语言样本表示,以实现其高精度的检测。为了证明我们基于发音表示的有效性,我们扩展了现有的基于深度长短期记忆(LSTM)神经网络的仇恨言论和攻击性语言防御模型,使用我们基于发音的仇恨言论和攻击性语言样本表示来训练该模型。我们的工作发现,基于发音的表示显著降低了数据集中的噪声,并提高了现有模型的整体性能。
Online hate speech and offensive language have been widely recognized as critical social problems. To defend against this problem, several recent works have emerged that focus on the detection and explanation of hate speech and offensive language using machine learning approaches. Although these approaches are quite effective in the detection and explanation of hate speech and offensive language samples, they do not explore the impact of the representation of such samples. In this work, we introduce a novel, pronunciation-based representation of hate speech and offensive language samples to enable its detection with high accuracy. To demonstrate the effectiveness of our pronunciation-based representation, we extend an existing hate-speech and offensive language defense model based on deep Long Short-term Memory (LSTM) neural networks by using our pronunciation-based representation of hate speech and offensive language samples to train this model. Our work finds that the pronunciation-based presentation significantly reduces noise in the datasets and enhances the overall performance of the existing model.
