摘要:

开发一个网络攻击性语言检测系统对网络用户的健康和安全有着重要的意义。研究表明,网络仇恨、在线骚扰和其他滥用技术的行为正在上升,特别是在2020年全球冠状病毒大流行期间。根据反诽谤联盟(ADL)的最新报告,35%的在线用户报告了与其基于身份的特征有关的在线骚扰,比2019年增加了3%。应用自然语言处理(NLP)领域的先进技术来支持在线无仇恨社区的发展是社会正义的一项关键任务。迁移学习通过允许将知识从一个域或一个数据集迁移到以前未见过的其他域或数据集来增强分类器的性能,从而支持分类器更具可推广性。在我们的研究中,我们将迁移学习的原理应用于跨多个阿拉伯语攻击性语言数据集,以比较对系统性能的影响。本研究旨在探讨微调和训练双向编码器表示从Transformers(BERT)模型上的多个阿拉伯语攻击性语言数据集单独和测试它使用其他数据集单独的效果。我们的实验从多个BERT模型之间的比较开始,以指导用于我们研究的主模型的选择。本研究亦探讨连结所有资料集以用于微调及训练BERT模型的效果。我们的研究结果表明,迁移学习对分类器性能的影响有限,特别是对于高度辩证的评论。

英文摘要:

Developing a system to detect online offensive language is very important to the health and the security of online users. Studies have shown that cyberhate, online harassment and other misuses of technology are on the rise, particularly during the global Coronavirus pandemic in 2020. According to the latest report by the Anti-Defamation League (ADL), 35% of online users reported online harassment related to their identity-based characteristics, which is a 3% increase over 2019. Applying advanced techniques from the Natural Language Processing (NLP) field to support the development of an online hate-free community is a critical task for social justice. Transfer learning enhances the performance of the classifier by allowing the transfer of knowledge from one domain or one dataset to others that have not been seen before, thus, supporting the classifier to be more generalizable. In our study, we apply the principles of transfer learning cross multiple Arabic offensive language datasets to compare the effects on system performance. This study aims at investigating the effects of fine-tuning and training Bidirectional Encoder Representations from Transformers (BERT) model on multiple Arabic offensive language datasets individually and testing it using other datasets individually. Our experiment starts with a comparison among multiple BERT models to guide the selection of the main model that is used for our study. The study also investigates the effects of concatenating all datasets to be used for fine-tuning and training BERT model. Our results demonstrate the limited effects of transfer learning on the performance of the classifiers, particularly for highly dialectic comments.
