There is no fixed NLP technique to manage language. To add more layers of information, you must employ various techniques while managing language. In getting started with NLP, it is vitally necessary to understand several language processing principles. 

It follows four steps.

  • The structure and relationship of words are determined by morphology. 
  • The words are used in a syntax manner or order to form sentences. 
  • With the help of semantic studies, the meaning of words is disclosed by lexical and grammatical structures. 
  • The simple contextual word meaning is pragmatics.
