- Overview

Natural language processing (NLP) is a branch of artificial intelligence (AI) that allows computers to understand spoken words and text in a similar way to humans. 

The five phases of NLP are: Lexical or morphological analysis, Syntax analysis, Semantic analysis, Discourse integration, Pragmatic analysis. 

Some NLP techniques include: 

  • Semantic analysis: Analyzes the grammatical structure of sentences to determine the relationships between independent terms.
  • Syntax analysis: Identifies the relationships between words and phrases within a sentence, and standardizes their structure.
  • Sentiment analysis: Determines whether data is positive, negative, or neutral.
  • Tokenization: Breaks characters, words, or subwords down into "tokens" that can be analyzed by a program.

 

Other NLP techniques include: 

  • Speech recognition
  • Word modeling
  • Vocabulary building
  • Frequent word occurrence
