The video provides a concise introduction to natural language processing (NLP) as an AI subfield that enables machines to understand and generate human language, which is inherently unstructured. It explains that NLP blends linguistic resources—such as grammatical rules, dictionaries, and heuristics—with statistical and machine‑learning approaches, including deep learning. The presenter lists major NLP applications like machine translation, virtual assistants/chatbots, sentiment analysis, summarization, text generation, and information extraction. The discussion then shifts to large language models (LLMs), describing them as a transformative development in NLP that relies on neural networks, particularly Transformer architectures trained on massive text corpora. Prominent LLMs mentioned are OpenAI’s GPT (ChatGPT), Google’s BERT and Gemini, Mistral AI’s Mistral, and Anthropic’s Claude.

Natural language processing, or NLP, is a field of artificial intelligence that makes it possible for a machine to understand and generate natural language. In other words, language spoken and written by humans and seen as a form of unstructured data. Although NLP uses machine learning and deep learning models, it also relies on mechanisms of its own such as classical linguistics, grammatical rules, dictionaries that provide canonical forms of words, heuristic methods for text analysis, etc. So we could say that NLP combines both linguistic and statistical approaches through artificial intelligence models, producing accurate and high-quality results. NLP is currently used in a wide range of popular applications, including machine translation, virtual assistants and chatbots, sentiment analysis, automatic summarization and text generation, information extraction, etc. LLMs, or large language models, represent a revolution in the field of NLP, as they use neural networks, especially Transformers based architectures trained on very large amount of text. The best known LLMs are GPT, the heart of ChatGPT from OpenAI, BERT and Gemini by Google, Mistral by Mistral AI, Claude from Anthropic, etc.
