Twitter Sentiment Analysis

information. Sentiment analysis is widely applied to understand the voice of the customer who has expressed opinions on various social media platforms.

Sentiment Analysis is the analysis of the feelings (i.e. emotions, attitudes, opinions, thoughts, etc.) behind the words by making use of Natural Language Processing (NLP) tools. Natural Language Processing essentially aims to understand and create a natural language by using essential tools and techniques.

Machine learning helps to train algorithm which scanned for the positive and negative word and based on that it scores the complete sentence. So the question whether Machine learning can correctly identifies 100% of the sentences. The answer is No, most the sentiment analysis algorithms achieves only 80% accuracy due to the complexity of natural language.
