In this study, sentiment analysis was conducted on tweets about distance education during the covid-19 process. As the data set, the data set provided with open access over the Kaggle data sharing platform was used. 999 records randomly retrieved from this dataset were manually labeled as positive or negative. A sentiment analysis model was established on KNIME.
