But first,

What is sentiment analysis?

Sentiment analysis is the use of natural language processing, text analysis, computational linguistics, and biometrics to systematically identify, extract, quantify, and analyze emotional states and subjective information.

More simply put, it is the process of identifying and categorizing the emotional tone of a piece of text. It can be used to determine whether a writer's attitude is positive, negative, or neutral.

Why do developers need a sentiment analysis API?

Developers need to know about the best sentiment analysis APIs because they help developers understand the mood of their users. Developers can use these APIs to build analysis tools and reports for better insights and better decisions.

According to a study by Zendesk, 49% of users who are unhappy with a brand are likely to tell others about their bad experiences through social media. This is just one of many reasons why it's important for developers to understand the mood of their users.
