Abstract:
Analysing the sentiments in online reviews assists in understanding customers’ satisfaction with a provided service or product, which gives the industry an opportunity to enhance the quality of their commodity, increase sales volume, develop marketing strategies, improve response to customers, promote customer satisfaction, and enhance the industry image. However, the studies focusing on applying machine learning algorithms and word embedding models, as well as deep learning techniques to classify the sentiments in reviews extracted from automobile forums, are arguably limited, and to fill this gap, this research addressed this area. Moreover, the research concentrated on categorizing positive, negative, and mixed sentiment categories in online forum reviews. The procedures for gathering and preparing the dataset are illustrated in this research. To perform the classification task, a set of models which include supervised machine learning, deep learning, and BERT word embedding is ad
opted in this research. The results show that the combination of the BERT word embedding model with the LSTM model produced the highest F1 score. Finally, the paper lays out recommendations to enhance the proposed system in future studies.
