ABSTRACT
The Covid-19 pandemic has changed the way people transact from physical bank to mobile banking transactions. The banks as financial companies are competing to offer the best service for mobile banking. Failure to fulfill consumer needs can damage a bank's reputation, profitability, and lead to gradual loss of customers. Hence, the bank needs to know its performance by measuring customer satisfaction. This study is aimed to know customer satisfaction of mobile banking using sentiment analysis. Sentiment analysis was conducted using data from Twitter, knowing that Twitter is a widely used media social with text-based content. The collected data was then predicted using the Support Vector Machine (SVM) model to get a positive or negative sentiment. From the model training result, this model achieved 92.5% of accuracy. The research analyzes customer satisfaction using sentiment analysis of BCA Mobile, Livin' by Mandiri, BRI Mobile (Brimo), and BNI Mobile. Brimo received the greatest percentage of positive sentiment compared to other platforms. Livin' by Mandiri and Brimo had a serious issue regarding its reliability. BCA Mobile should be more concerned regarding its usefulness. Meanwhile, BNI Mobile should have been more worried about its platform responsiveness. © 2022 IEEE.
