Information flows fast, and social media has much of it. Twitter has a vast database, but most of it is unclear. Text mining helps uncover information in unstructured text. Twitter users searched for COVID-19 vaccine information most during the outbreak. The COVID-19 vaccination dispute continues on social media, with pros and drawbacks. Hence, data analysis is needed to understand COVID-19 vaccination public opinion better. The sentiment model analyzes text data to identify sentiments about the government’s program. Comparing classification performance requires the optimization algorithm. Neural Network (NN) and Support Vector Machine (SVM) sentiment studies determine COVID-19 vaccination program public opinion. SVM performs best with an 88% Receiver Operating Characteristic (ROC) score. The study emphasizes the need to enhance algorithms for text mining and sentiment analysis to determine and comprehend public opinion on an issue. © 2024 selection and editorial matter, Aji Prasetya Wibawa.
