Natural Language Processing (NLP)

Natural Language Processing (NLP) is the branch of AI concerned with the interaction between computers and human language. NLP enables machines to read, understand, and generate text in a way that is both meaningful and useful.

Core NLP tasks:

• Text Classification: Spam detection, sentiment analysis
• Named Entity Recognition: Identifying people, places, organizations in text
• Machine Translation: Translating between languages
• Text Summarization: Condensing long documents
• Question Answering: Providing accurate answers to queries
• Text Generation: Creating coherent written content

NLP has been transformed by the transformer architecture and large language models. Modern NLP systems achieve human-level or near-human-level performance on many benchmarks, though challenges like reasoning, truthfulness, and bias remain active research areas.
