Definition
Natural Language Processing (NLP) is a field of artificial intelligence focused on enabling computers to understand, interpret, and generate human language. It bridges the gap between human communication and computer comprehension, allowing machines to process text and speech in a way that is meaningful. NLP works by applying algorithms and statistical models to analyze linguistic patterns, syntax, semantics, and context within data. This capability is crucial for automating tasks, extracting insights from vast amounts of unstructured text, and improving human computer interaction. For instance, NLP powers virtual assistants like Siri or Alexa, allowing them to respond to spoken commands. It differs from simple keyword matching by understanding the nuances and intent behind words, not just their presence. NLP concepts are frequently tested in domains like data analysis, cybersecurity threat intelligence, and project management software.
