Natural Language Processing (NLP) is a subfield of Artificial Intelligence that deals with the interaction between humans and computers using natural language. It involves the development of algorithms and models that can analyze, understand, and generate human language. NLP is a multidisciplinary field that draws on linguistics, computer science, and statistics to build systems that can understand and generate human language. It has a wide range of applications, from chatbots to automated translation systems to sentiment analysis. Some of the core components of NLP include text preprocessing, feature extraction, language modeling, and machine learning algorithms.
