Definition
Natural Language Processing (NLP) is a field of artificial intelligence that enables computers to understand, interpret, and generate human language. It combines computational linguistics with machine learning models to process text and speech data. NLP works by breaking down language into smaller components, identifying patterns, and applying algorithms to derive meaning or perform tasks. This capability is crucial for automating tasks, extracting insights from unstructured data, and improving human computer interaction. For instance, NLP powers virtual assistants like Siri and Alexa, allowing them to respond to voice commands. It differs from simple keyword matching by understanding context, sentiment, and intent. NLP concepts are relevant in domains like data analytics, cybersecurity threat intelligence analysis, and AI development, appearing in certifications such as AWS Certified Solutions Architect Associate.
