Natural Language Processing (NLP) concerns interactions between computers and human (natural) languages. The goal is to enable computers to process, understand, and generate human language. NLP involves various tasks, such as text classification, sentiment analysis, translation, question-answering, and text summarization. These tasks are typically achieved through machine learning algorithms and deep learning models, such as neural networks.

Examples of NLP applications include chatbots, virtual assistants, language translation services, and text-to-speech systems.
