A person's feelings or emotions can usually be seen by their behavior, tone of voice, and expression.

“…The more datasets used, the better the accuracy of the data obtained. In addition, TF-IDF (Term Frequency-Inverse Document Frequency) must also be considered in word weighting (Alfarizi et al, 2022). In developing technology in the digital era, like today, chatbot services are needed to maximize the provision of information to students.…”
