Sentiment Analysis Example

For example, in a study conducted by a student at Oklahoma State University, Amazon reviews were analyzed to find out brand preference. Samsung phone models (Galaxy S6 & Galaxy S7) and Apple (iPhone 6 & iPhone 7) were used for the study. It came out that customers who had a higher preference for a reliable battery and a good screen went on to buy Samsung phones. In contrast, iPhones were preferred by customers who are more attracted to design and camera.

Filtering comments by topic and sentiment, you can also find out which features are necessary and which must be eliminated. Armed with sentiment analysis, the product development team of an organization will know the features that customers are looking for.
