The Use of Machine Learning Classifiers to Evaluate the Sentiment Categories of ChatGPT-Related Tweets
This study evaluates the performance of conventional machine learning classifiers for sentiment analysis of ChatGPT-related tweets. While deep learning approaches have demonstrated advanced capabilities, their substantial computational requirements present practical limitations. Using a dataset of 219,294 tweets from November 2022 to April 2023, we assess four classifiers (Logistic Regression, Support Vector Machines, Random Forest, and Naive Bayes) with two feature extraction techniques (Bag of Words and TF-IDF) across balanced and imbalanced datasets. Results indicate that Linear SVM with TF-IDF vectorization achieves the highest accuracy (84.02%) and macro F1-score (80.81%) without balancing techniques. Random Forest with Bag of Words and balancing techniques shows competitive performance (80.08% macro F1-score), while Naive Bayes consistently underperforms across configurations. n-gram analysis reveals predominantly positive public sentiment toward ChatGPT, focusing on capabilities and utility, while negative sentiments center on performance limitations and broader AI implications. This research provides empirical insights into sentiment analysis methodologies for emerging AI technologies and demonstrates the continued effectiveness of conventional machine learning approaches in resource-constrained environments.
