Natural Language Processing (NLP)

Definition

Natural Language Processing (NLP) is a branch of artificial intelligence that gives computers the ability to understand, interpret, and generate human language in a valuable way. NLP combines computational linguistics (rule-based modeling of human language) with machine learning and deep learning to process text and speech. Key NLP capabilities include: sentiment analysis (determining emotional tone), named entity recognition (identifying people, places, brands), text classification (categorizing content), machine translation (Google Translate), text summarization, question answering, and text generation (ChatGPT). In marketing, NLP powers: chatbots and virtual assistants, social media monitoring and sentiment analysis, email subject line optimization, content creation assistance, voice search optimization, and customer feedback analysis. Modern large language models (LLMs) like GPT-4 and Claude use advanced NLP to understand context, nuance, and generate human-like responses.
