"Text analysis is the process of examining written communications to discover trends or create meaning. It involves sentiment analysis, key phrase extraction, and entity recognition. It usually is used with customer communications to improve a product or service. While working on a recent project to determine which of our company's services customers found the easiest to use, I analyzed email exchanges between the sales team and their customers. The results revealed that while customer surveys indicated that one service was the most popular, the email exchanges found that the customers actually enjoyed using another service more. This enabled the company to adopt some of the features of this service to improve customer satisfaction with the other ones we offered."
