Natural Language Processing (NLP) is a branch of artificial intelligence that focuses on enabling computers to understand and process human language. It involves techniques such as text analysis, speech recognition, natural language understanding, and natural language generation. NLP relies on machine learning algorithms to develop models that can interpret and process human language. These models are then used to create applications that can understand and respond to natural language input. These applications can be used for various tasks such as automated customer support, sentiment analysis, text summarization, machine translation, and more. NLP is an important part of the artificial intelligence field and is used to enable computers to understand and respond to human language.
