SENTIMENT ANALYSIS COVID VACCINE ON TWITTER USING SVM ALGORITHM

Currently there are still many people who have not been vaccinated. many people comment on social media, especially the twitter application, to provide opinions and comments about the covid vaccine in Indonesia. In order to find out which tweets appeared including positive comments or negative comments, an analysis was carried out to find out how many negative and positive comments were by sentiment analysis. This study analyzes comments taken from the twitter application using the crawling method. Furthermore, pre-processing will be carried out such as case folding, tokenization, and stopword filtering. Then before the classification is carried out, data labeling and data split will be carried out to facilitate classification. After that, classification will be carried out using the SVM algorithm method. The final result of this research project is that there are 9981 data obtained from the crawling method. This data proves that 92.4% of Indonesians gave a neutral response to the topic of the Covid vaccine on the Twitter application. The SVM algorithm is easy to use in the implementation of sentiment analysis. And the accuracy results obtained using the SVM method are very high at 90.5%.
