SMU Data Science Review
Abstract
This study investigates a comparison of classification models used to determine aspect based separated text sentiment and predict binary sentiments of movie reviews with genre and aspect specific driving factors. To gain a broader classification analysis, five machine and deep learning algorithms were compared: Logistic Regression (LR), Naive Bayes (NB), Support Vector Machine (SVM), and Recurrent Neural Network Long-Short-Term Memory (RNN LSTM). The various movie aspects that are utilized to separate the sentences are determined through aggregating aspect words from lexicon-base, supervised and unsupervised learning. The driving factors are randomly assigned to various movie aspects and their impact tied to each aspect and genre leading to the sentiment classification has been fully investigated based on the accuracy of each model. The study shows that assigning higher driving factors to certain aspects and genre result in the higher accuracy of the sentiment prediction models that utilized in this research.
