DeepSentiPers: Novel Deep Learning Models Trained Over Proposed Augmented Persian Sentiment Corpus

Sentiment Analysis in Persian Using Deep Neural Networks

Binary and multiclass sentiment detection using deep neural architectures (BLSTM and CNN) on Persian augmented texts

NB: DeepSentiPers is a modified version of our paper presented at the fifth computational linguistics conference in Iran. <br> https://arxiv.org/pdf/2004.05328.pdf

This study uses deep neural networks to extract opinions from each Persian sentence-level text. Deep learning models have introduced a new way to boost output quality. However, these architectures require large annotated datasets and must be carefully designed. To the best of our knowledge, we not only suffer from a lack of well-annotated Persian sentiment corpora but also from the absence of a novel model capable of classifying Persian opinions for both multi-class and binary classification tasks. Therefore, our study first proposes two novel deep learning architectures, comprising bidirectional LSTM and CNN layers. These architectures form part of a precisely designed deep neural hierarchy and can classify sentences for both tasks. Second, we propose three data augmentation techniques for the low-resource Persian sentiment corpus. Our comprehensive experiments on three baselines and two different neural word embedding methods demonstrate that our data augmentation strategies and proposed models successfully address the research objectives.
