What is NLP in AI?

Natural Language Processing (NLP) bridges the gap between human language and machine understanding. It enables computers to interpret, analyze, and respond to text and speech in a way that mimics human comprehension. NLP combines computational linguistics, machine learning, and deep learning techniques to enhance communication between humans and AI systems.

Key Components of NLP

Tokenization:
Splitting text into smaller units, such as sentences, phrases, or individual words, to facilitate processing.
Lemmatization and Stemming:
Reducing words to their base or root forms. For example, “running” becomes “run” during lemmatization.
Parsing:
Analyzing sentence structures to understand grammatical relationships between words.
Named Entity Recognition (NER):
Identifying and categorizing key entities, such as names, places, organizations, and dates.
Sentiment Analysis:
Determining the sentiment or emotional tone within a piece of text, whether positive, negative, or neutral.
Stop Word Removal:
Filtering out common, non-informative words such as “the,” “is,” and “in” to focus on more meaningful terms.
