Natural Language Processing

· Natural Language Processing (NLP) is the branch of  Artificial Intelligence and Computational Linguistics and helps in interaction between the computer and natural languages.

· The common NLP tasks included in the software are sentence segmentation, part-of-speech tagging and parsing.

The different logical steps in NLP are:

Morphological analysis:
In this step, the punctuations are separated from the sentences.

Syntax analysis (Parsing):
It basically involves the stages of lexical analysis and grammar. The linear sequence of words are transformed into structures and further specifies how words relate to each other.

Semantic analysis: 
In this step, the meanings are assigned to the structures which are initially created in parsing. 

Pragmatic analysis: 
It involves re-interpretation of language , verification and generation of final output result.
