Natural Language Processing is a way for computer systems like robots to learn and mimic the human language. It helps intelligent systems decode the meaning of human sentences and master communication. NLP tools are important for businesses that work with huge amounts of unstructured data, be it emails, social media conversations, survey responses, and data in other forms. Companies can analyze data to find what is trending amidst the pools of data and use those insights to automate tasks and make business decisions. Popular applications of NLP technology are in sentiment analysis, where machines learn to understand common human feelings like sarcasm to detect fake news online, text classification that brings order to unstructured data by making sense out of it, in chatbots and virtual assistants to make them smarter and obey commands better, and improves auto-correct and speech recognition software.
