摘要:

随着社交媒体上用户生成的网络内容呈指数级增长,互联网不同部分对个人或群体的辱骂性语言也在迅速增加。对于人类版主来说,识别攻击性内容并将其过滤掉是非常具有挑战性的。深度神经网络已经显示出在仇恨语音检测和相关应用中具有合理准确性的前景。然而,分类器严重依赖于训练数据的大小和质量。如此高质量的大数据集并不容易获得。此外,最近出现的现有数据集并不是按照相同的注释准则创建的,而且往往涉及与仇恨有关的不同类型和子类型。为了解决这个数据稀疏性问题,并获得更多的全球代表性的功能,我们提出了一个卷积神经网络(CNN)的多任务学习模型(MTLs)\footnote{code is available at https://github.com/imprasshant/STL-MTL},利用来自多个来源的信息。在三个基准数据集上进行的实证分析表明,所提出的方法的有效性与显着改善的准确性和F分数,以获得最先进的性能相对于现有的系统。

英文摘要:

With the exponential rise in user-generated web content on social media, the proliferation of abusive languages towards an individual or a group across the different sections of the internet is also rapidly increasing. It is very challenging for human moderators to identify the offensive contents and filter those out. Deep neural networks have shown promise with reasonable accuracy for hate speech detection and allied applications. However, the classifiers are heavily dependent on the size and quality of the training data. Such a high-quality large data set is not easy to obtain. Moreover, the existing data sets that have emerged in recent times are not created following the same annotation guidelines and are often concerned with different types and sub-types related to hate. To solve this data sparsity problem, and to obtain more global representative features, we propose a Convolution Neural Network (CNN) based multi-task learning models (MTLs)\footnote{code is available at https://github.com/imprasshant/STL-MTL} to leverage information from multiple sources. Empirical analysis performed on three benchmark datasets shows the efficacy of the proposed approach with the significant improvement in accuracy and F-score to obtain state-of-the-art performance with respect to the existing systems.
