Natural Language Processing (NLP) is a field at the intersection of computer science, artificial intelligence, and linguistics. Its goal is to enable computers to understand, interpret, and generate human language in a way that is both valuable and meaningful. NLP encompasses a wide range of techniques and tools that allow computers to process and analyze large amounts of natural language data. The challenges in NLP include speech recognition, natural language understanding, and natural language generation, which involve understanding grammar, context, sentiments, and the nuances of language.
