论文摘要
在Twitter数据中表达的情绪的自动识别具有广泛的应用。我们通过将中性类添加到一个由四种情绪组成的基准数据集中添加中性类来创建一个均衡的数据集：恐惧，悲伤，喜悦和愤怒。在此扩展数据集上，我们研究了来自变形金刚（BERT）的支持向量机（SVM）和双向编码器表示情感识别的使用。我们通过组合两个BERT和SVM模型来提出一种新颖的集合模型。实验表明，所提出的模型在推文中的情绪识别方面达到了0.91的最新精度。
Automatic identification of emotions expressed in Twitter data has a wide range of applications. We create a well-balanced dataset by adding a neutral class to a benchmark dataset consisting of four emotions: fear, sadness, joy, and anger. On this extended dataset, we investigate the use of Support Vector Machine (SVM) and Bidirectional Encoder Representations from Transformers (BERT) for emotion recognition. We propose a novel ensemble model by combining the two BERT and SVM models. Experiments show that the proposed model achieves a state-of-the-art accuracy of 0.91 on emotion recognition in tweets.
