摘要:

互联网和社交媒体的普及使仇恨言论内容能够在推特等微博平台上迅速匿名传播。目前欧盟和美国针对仇恨语言的立法,加上这些平台产生的大量数据,导致自动工具成为仇恨语音检测任务和管道的必要组成部分。在这项研究中,我们研究了几种不同的文本表示技术与多个分类算法配对,在自动仇恨语音检测和辱骂性语言歧视任务的性能。我们对二进制和多类数据集进行了实验评估,并进行了显著性测试。我们的研究结果表明,简单的仇恨关键词频率特征(BoW)效果最好,其次是预训练的词嵌入(GLoVe)以及N-gram图(NGG):一种基于图形的表示,证明可以为这项任务产生高效,非常低维但丰富的特征。这些表示与逻辑回归或3层神经网络分类器的组合在微观和宏观F测量方面实现了最佳的检测性能。

英文摘要:

The pervasiveness of the Internet and social media have enabled the rapid and anonymous spread of Hate Speech content on microblogging platforms such as Twitter. Current EU and US legislation against hateful language, in conjunction with the large amount of data produced in these platforms has led to automatic tools being a necessary component of the Hate Speech detection task and pipeline. In this study, we examine the performance of several, diverse text representation techniques paired with multiple classification algorithms, on the automatic Hate Speech detection and abusive language discrimination task. We perform an experimental evaluation on binary and multiclass datasets, paired with significance testing. Our results show that simple hate-keyword frequency features (BoW) work best, followed by pre-trained word embeddings (GLoVe) as well as N-gram graphs (NGGs): a graph-based representation which proved to produce efficient, very low-dimensional but rich features for this task. A combination of these representations paired with Logistic Regression or 3-layer neural network classifiers achieved the best detection performance, in terms of micro and macro F-measure.
