Emotion Detection Sentiment Analysis
This is a more sophisticated way of identifying the emotion in a piece of text. Lexicons and machine learning are used to determine the sentiment. Lexicons are lists of words that are either positive or negative. This makes it easier to segregate the terms according to their sentiment. The advantage of using this is that a company can also understand why a customer feels a particular way. This is more algorithm-based and might be complex to understand at first.

This is a deeper understanding of the intention of the customer. For example, a company can predict if a customer intends to use the product or not. This means that the intention of a particular customer can be tracked, forming a pattern, and then used for marketing and advertising.
Different methods are used for these different types of sentiment analysis – while one is rule-based, the other is automatic. Rule-based sentiment analysis is more rigid and might not always be accurate. It involves the natural language processing (NLP) routine. On the other hand, automatic sentiment analysis is more detailed and in-depth. Machine learning is used to decode the feedback provided by each customer. So, there is more precision and flexibility here.

What is sentiment analysis?
Sentiment analysis is the process of gathering and assessing opinions spread on the internet. It can also be defined as the process of determining attitude of internet users towards a particular object. Sentiment analysis is done using a variety of techniques which can be divided into two categories: opinion mining and social media analytics. The two techniques are different but used for the same purpose; that of analyzing the public's opinion on a particular issue or subject.
What are the differences between opinion mining and social media analytics?
Opinion mining is the process of identifying and categorizing opinions on a particular subject from online journals, blogs, and other forms of discourse. The process of identifying these opinions is called opinion extraction. Social media analytics on the other hand is the process of analyzing the sentiments about a particular issue or subject using the tools and techniques available in social media. For example, a website can query tweets to determine people's perception on a particular news event.
