What are Sentiment Analysis Tools, and How They Work

Sentiment analysis is a process of conversation research. It uses NLP and ML to report on customer emotions. Other names for it are opinion mining, text analysis, and emotion AI. 

Tools for sentiment analysis examine the emotions in text or audio/visual messages. They determine if the content is positive, negative, or neutral.

These tools track reviews, feedback, surveys, and customer support chats online. They search for emotional keywords and analyze data. Then, they present the information in charts or graphs to show customer feedback and opinions about the business.

Using a sentiment analysis tool is an effective way to learn about brand reputation and customers’ emotions from a high volume of unstructured data and conversation. However, you should select the right tool based on your business type, size, and needs. 

The tool designed for customer sentiment analysis may not serve your purpose if you want to track and analyze social mentions and hashtags. 

Hence, it is recommended that you use the trial version of your desired software before subscribing to a paid plan.
