Natural Language Processing Basics
Natural Language Processing (NLP) Basics refers to the foundational concepts and techniques used to enable computers to understand, interpret, and generate human language. This includes tasks such as tokenization, part-of-speech tagging, stemming, lemmatization, and syntactic parsing. NLP combines linguistics, computer science, and artificial intelligence to analyze text and speech, making it possible for machines to process and respond to human communication in applications like chatbots, translation, and sentiment analysis.

❓ Frequently Asked Questions
What is Natural Language Processing (NLP)?
NLP is a field of AI that enables computers to understand, interpret, and generate human language, turning text and speech into useful information.
What is tokenization in NLP?
Tokenization splits text into smaller units (tokens), such as words or sentences, to make analysis easier.
What is stemming vs lemmatization?
Stemming trims word endings to produce a crude base form, while lemmatization maps a word to its dictionary form (lemma) using linguistic rules.
What is part-of-speech tagging?
Part-of-speech tagging assigns each word a grammatical category (noun, verb, adjective, etc.) to help understand sentence structure.
What is syntactic parsing?
Syntactic parsing analyzes sentence structure to reveal relationships between words, such as subject–verb relationships or how words group into phrases.
