Foundational Concepts
Natural Language Processing (NLP)
The branch of AI that helps computers understand and generate human language.
Definition
Natural language processing is the set of techniques that allow computers to work with the messy, ambiguous, context-dependent way humans communicate. Unlike programming languages, which follow strict rules, human language is full of idioms, implied meaning, and variation. NLP covers everything from grammar checking and translation to sentiment analysis and document understanding. Modern LLMs represent the most advanced form of NLP to date.
