Collecting and analyzing social media posts to understand consumer perceptions is an example of sentiment mining, which involves using technology to analyze language and emotions in order to gauge public opinion.

An experiment involves manipulating variables to test a hypothesis, whereas sentiment mining is focused on observing and analyzing natural behaviors and opinions.
