摘要:

虽然情感分类的研究在高资源语言中取得了显着进展,但对于孟加拉语等资源受限的语言来说,这仍然是一个起步阶段。然而,缺乏必要的语言处理工具和基准语料库的不足,使得孟加拉语的情感分类任务更具挑战性和复杂性。这项工作提出了一种基于transformer的技术,将孟加拉语文本分类为六种基本情绪之一:愤怒,恐惧,厌恶,悲伤,喜悦和惊讶。孟加拉语情感语料库由6243文本的分类任务。使用各种机器学习(LR、RF、MNB、SVM)、深度神经网络(CNN、BiLSTM、CNN+BiLSTM)和基于Transformer(Bangla-BERT、m-BERT、XLM-R)的方法进行实验。实验结果表明,XLM-R通过在测试数据上实现最高加权$f_1$ -评分$69.73\%$而优于所有其他技术。该数据集可在https://github.com/omar-sharif03/NAACL-SRW-2021上公开获得。

英文摘要:

Although research on emotion classification has significantly progressed in high-resource languages, it is still infancy for resource-constrained languages like Bengali. However, unavailability of necessary language processing tools and deficiency of benchmark corpora makes the emotion classification task in Bengali more challenging and complicated. This work proposes a transformer-based technique to classify the Bengali text into one of the six basic emotions: anger, fear, disgust, sadness, joy, and surprise. A Bengali emotion corpus consists of 6243 texts is developed for the classification task. Experimentation carried out using various machine learning (LR, RF, MNB, SVM), deep neural networks (CNN, BiLSTM, CNN+BiLSTM) and transformer (Bangla-BERT, m-BERT, XLM-R) based approaches. Experimental outcomes indicate that XLM-R outdoes all other techniques by achieving the highest weighted $f_1$-score of $69.73\%$ on the test data. The dataset is publicly available at https://github.com/omar-sharif03/NAACL-SRW-2021.
