Abstract
There are tens of thousands of unstructured textual data generated from social media platforms every day, as well as vast sensitive words that may spread harmful information and even insult with each other. Therefore, effectively identifying sensitive words on the network, can not only filter out these inappropriate remarks, but also build a healthy and clean network environment. Recently, there are many researchers devote themselves into the study of emotional vocabulary, just fewer studies draw attention to the identification of sensitive vocabulary on the network. Furthermore, traditional methods of vocabulary recognition need a lot of manpower to make rules and extract features. In this paper, we firstly construct the dataset of uncivilized language (ULN dataset), which is acquired through web crawler on the website. Secondly, we propose a method to identify Chinese sensitive words on the network, which combine the Bidirectional Encoder Representations from Transformers with Bidirectional Long Short Term Memory Network and Conditional Random Field (BERT-BiLSTM-CRF). We use three models to identify sensitive words in ULN dataset. The experimental results show that, the model proposed in this paper has excellent performance, compared with the classical Bidirectional Long Short Term Memory Network (BiLSTM-CRF) and Convolutional Neural Network (CNN).
