abstract = {Online media has an increasing presence on the restaurants' activities through social media
websites, coinciding with an increase in customers' reviews of these restaurants. These reviews become
the main source of information for both customers and decision-makers in this field. Any customer who
is seeking such places will check their reviews first, which usually affect their final choice. In addition,
customers' experiences can be enhanced by utilizing other customers' suggestions. Consequently, customers'
reviews can influence the success of restaurant business since it is considered the final judgment of the overall
quality of any restaurant. Thus, decision-makers need to analyze their customers' underlying sentiments in
order to meet their expectations and improve the restaurants' services, in terms of food quality, ambiance,
price range, and customer service. The number of reviews available for various products and services
has dramatically increased these days and so has the need for automated methods to collect and analyze
these reviews. Sentiment Analysis (SA) is a field of machine learning that helps analyze and predict the
sentiments underlying these reviews. Usually, SA for customers' reviews face imbalanced datasets challenge,
as the majority of these sentiments fall into supporters or resistors of the product or service. This work
proposes a hybrid approach by combining the SupportVector Machine (SVM) algorithm with Particle Swarm
Optimization (PSO) and different oversampling techniques to handle the imbalanced data problem. SVM is
applied as a machine learning classi cation technique to predict the sentiments of reviews by optimizing the
dataset, which contains different reviews of several restaurants in Jordan. Data were collected from Jeeran,
a well-known social network for Arabic reviews. A PSO technique is used to optimize the weights of the
features, as well as four different oversampling techniques, namely, the Synthetic Minority Oversampling
Technique (SMOTE), SVM-SMOTE, Adaptive Synthetic Sampling (ADASYN) and borderline-SMOTE
were examined to produce an optimized dataset and solve the imbalanced problem of the dataset. This study
shows that the proposed PSO-SVM approach produces the best results compared to different classiffication
techniques in terms of accuracy, F-measure, G-mean and Area Under the Curve (AUC), for different versions
of the datasets.},
