摘要:

近年来,社交媒体平台Twitter上针对妇女的在线虐待行为引起了相当大的关注。一种有效识别厌女症虐待的自动化方法可以提高我们对持续一段时间内与虐待性推文相关的模式、驱动因素和反应有效性的理解。然而,训练一个神经网络(NN)模型与一个小的一组标记的数据来检测厌恶女性的推文是困难的。这部分是由于包含厌恶女性内容的推文的复杂性,以及在NN模型中需要学习的大量参数。我们已经进行了一系列的实验,以探讨如何训练神经网络模型,以有效地检测厌恶女性的推文。特别是,我们已经定制和正则化了卷积神经网络(CNN)架构,并表明在特定任务域上预训练的词向量可以用于在少量标记数据可用时有效地训练CNN模型。以这种方式训练的CNN模型与最先进的模型相比提高了准确性。

英文摘要:

Online abuse directed towards women on the social media platform Twitter has attracted considerable attention in recent years. An automated method to effectively identify misogynistic abuse could improve our understanding of the patterns, driving factors, and effectiveness of responses associated with abusive tweets over a sustained time period. However, training a neural network (NN) model with a small set of labelled data to detect misogynistic tweets is difficult. This is partly due to the complex nature of tweets which contain misogynistic content, and the vast number of parameters needed to be learned in a NN model. We have conducted a series of experiments to investigate how to train a NN model to detect misogynistic tweets effectively. In particular, we have customised and regularised a Convolutional Neural Network (CNN) architecture and shown that the word vectors pre-trained on a task-specific domain can be used to train a CNN model effectively when a small set of labelled data is available. A CNN model trained in this way yields an improved accuracy over the state-of-the-art models.
