What is sentiment analysis?

Quite literally, sentiment analysis is the process of analyzing the emotions, feeling, or sentiment behind the textual or audial/visual (emojis) data with the help of a sentiment analysis software. This software analyzes text or audio based on the preprogrammed algorithm.

Sentiment analysis tools use Natural Language Processing or NLP to determine whether a piece of text is positive, negative, or neutral. Some sentiment analysis tools go beyond that and can even assign more detailed sentiment markers such as disappointment, excitement, or disgust to a piece of text. Sentiment analytics are often performed on text data sourced from social media, such as online reviews, emails, customer support chats, survey responses, blogs, and news items. In addition to that, some sentiment analysis tools can analyze voice clips or even analyze ongoing phone calls by applying Natural Language Processing logic to analyze the tone of voice.

The precision of the sentiment analytics software depends on the analysis algorithm it uses. It’s important to note that no sentiment analysis tools are 100% error-proof, no matter if it’s free or so expensive you can barely justify it. People often use sarcasm and slang in their communication which is hard to pick up even for the most advanced  sentiment analysis tools. However, when you’re dealing with hundreds or thousands of messages from various channels every day, automating sentiment analysis is always much more efficient than combing through them manually.
