ABSTRACT
Natural language processing (NLP) is a subfield of artificial intelligence (AI) and a research area in the field of computer science recently. It is processed by the computer system and understands the concept which is given as text input and generates some meaningful results. There are many subfields of NLP like machine translation, information retrieval (IR), information extraction (IE), and question answering. There are different types of natural languages are available in India even if in worldwide labels like Hindi, Odia, Bengali, Marathi, French, Spanish, German, etc. But different language has a different grammatical structure and rules. Most of the Indian languages are morphologically rich language. The process of natural language is mean to understand by the machine properly then processed it carefully and generates another natural language in the errorless manner by applying some intelligent computing algorithm. As per the mathematician or computer scientist, without algorithm the process of natural language is meaningless and will not to be produce output in proper format. Intelligent Computing is a method, ability to learn knowledge and specific task from the data set across a specified domain or experimental observation. The role of intelligent computing having various computational algorithms like machine learning, deep learning 254are applied in various parts of NLP like machine translation, sentiment analysis, IR, extraction, etc.
