Natural Language processing is today a fast-emerging technology area. It has also been one of the most difficult topics to handle for the computers. Thanks to the advancement in artificial intelligence, we can process natural language more easily today. Many business applications today leverage the power of NLP. With the perfection on speech to text and text to speech conversions, NLP tools are used today as personal assistants and robo advisors.
