The best way to start to explain sentiment analysis is to first define exactly what it is. So, sentiment analysis is technology that identifies the sentiment behind written text.
That written text could be from emails, blog comments, online reviews. It could come from social media messages, or live chat conversations. Whatever the source or medium, sentiment analysis would run the message through its algorithm to calculate the mood it holds.
From there, it produces a sentiment score from 1-100. This score can be based on whichever metric you’re keen to measure: from customer satisfaction levels to sales probability.
In a nutshell, sentiment analysis is the process of taking text and analysing it for the mood it reveals.
