Natural Language Processing in AI

What is NLP?

Natural Language Processing (NLP) is the branch of AI that enables computers to understand, interpret, and generate human language — both written and spoken.

Core NLP Tasks

• Tokenization: Splitting text into words or subwords.
• Named Entity Recognition (NER): Identifying names, places, and organizations.
• Sentiment Analysis: Determining the emotional tone of text.
• Machine Translation: Converting text between languages.
• Text Summarization: Condensing long text into key points.

How Modern NLP Works

Modern NLP relies on transformer architectures, which use self-attention mechanisms to understand context across long passages of text, powering models like GPT and BERT.

Applications of NLP

• Chatbots and virtual assistants.
• Search engines.
• Email spam filtering.
• Voice assistants like Siri and Alexa.
