What is Natural Language Processing?
Natural Language Processing (NLP) is a branch of artificial intelligence concerned with giving computers the ability to understand, interpret, and manipulate human language. NLP bridges the gap between human communication and computer understanding.
How does it work?
NLP combines computational linguistics (rule-based modeling of human language) with statistical machine learning and deep learning models. It breaks down language into its elemental pieces, analyzes the grammatical structure, and extracts the intended meaning or sentiment from the text or audio.
What is a simple example?
When you ask a smart speaker "What's the weather like?", the device uses NLP to convert your audio into text, identify that "weather" is the core subject, determine the intent of your question, and formulate a relevant spoken response. Email spam filters and grammar checking software also rely heavily on NLP.
Why does it matter?
Human language is messy. It contains sarcasm, idioms, varying accents, and ambiguous sentence structures. Traditional computer programming requires strict syntax to function. NLP is the technology that allows humans to interact with software naturally, without having to write code or memorize rigid commands.
