The foundation of this study is based on the Kano model. This model was initially used by making a questionnaire survey. But now a days due to vast amount of data and opinions available via the internet on the World Wide Web the model can be changed. In this study data from an e-commerce site has been collected and has undergone preprocessing, sentiment analysis and then Kano evaluation to understand how to satisfy a customer. The use of the said model overcomes the disadvantages of the sentiment analysis. In this study a combination of sentiment analysis and Kano model has been done on online comment data giving us picture of how to discover the demands of a customer and also how to satisfy him.
