  • NLU involves the two tasks -
    • Used to map the given input into useful representation.
    • Used to analyze different aspects of the language.

2. Natural Language Generation (NLG)

  • Natural Language Generation (NLG) acts as a translator that converts the computerized data into natural language representation.
  • It involves in Text planning, Sentence planning, and Text Realization.

Note: The NLU is difficult than NLG.
