摘要:

这项工作详细比较了深度学习模型的性能,如卷积神经网络(CNN),长短期记忆(LSTM),门控递归单元(GRU),它们的混合体,以及一系列用于阿拉伯语评论情感分析的浅层学习分类器。此外,比较还包括最先进的模型,如Transformer架构和araBERT预训练模型。本研究中使用的数据集是多方言阿拉伯语酒店和书评数据集,这些数据集是阿拉伯语评论的一些最大的公开数据集。结果显示,与文献中报道的类似工作的结果相比,深度学习在二进制和多标签分类方面优于浅层学习。结果的这种差异是由数据集大小引起的,因为我们发现它与深度学习模型的性能成正比。深度和浅层学习技术的性能在准确性和F1得分方面进行了分析。表现最好的浅层学习技术是随机森林,其次是决策树和AdaBoost。使用默认嵌入层的深度学习模型表现相似,而Transformer模型在使用araBERT增强时表现最佳。

英文摘要:

This work presents a detailed comparison of the performance of deep learning models such as convolutional neural networks (CNN), long short-term memory (LSTM), gated recurrent units (GRU), their hybrids, and a selection of shallow learning classifiers for sentiment analysis of Arabic reviews. Additionally, the comparison includes state-of-the-art models such as the transformer architecture and the araBERT pre-trained model. The datasets used in this study are multi-dialect Arabic hotel and book review datasets, which are some of the largest publicly available datasets for Arabic reviews. Results showed deep learning outperforming shallow learning for binary and multi-label classification, in contrast with the results of similar work reported in the literature. This discrepancy in outcome was caused by dataset size as we found it to be proportional to the performance of deep learning models. The performance of deep and shallow learning techniques was analyzed in terms of accuracy and F1 score. The best performing shallow learning technique was Random Forest followed by Decision Tree, and AdaBoost. The deep learning models performed similarly using a default embedding layer, while the transformer model performed best when augmented with araBERT.
