Another way sentiment analysis software can be used is to find out how your employees are thinking about your company by analyzing employee communications. It might be nice to know what the internal mindset is at any given time or on some specific topic. Of course, I could see a lot of very unpleasant terms being used repeatedly once your employees are aware that all of their communications are being analyzed. Some companies do a version of this by monitoring employees Facebook posts, so it isn't as much of a leap as it sounds. If a company is very careful to ensure that individuals are not specifically identifiable, I could see this as a valid and useful use of text analytics, but you would have to treat very carefully through the privacy minefield not to end up with a bunch of outraged employees.
