NLP stands for Natural Language Processing. It is a field of artificial intelligence and linguistics that deals with the interaction between human language and computers. NLP involves developing algorithms and models that enable computers to understand, interpret, and generate human language.

NLP encompasses a range of techniques, including text analysis, sentiment analysis, speech recognition, machine translation, and question answering. These techniques involve processing and analyzing large amounts of text and speech data, using statistical and machine learning methods, to extract insights and meaning.

NLP is used in a variety of applications, including chatbots, voice assistants, virtual agents, language translation, social media analysis, and sentiment analysis. It has also been applied in various industries such as healthcare, finance, and education, to help automate tasks and improve efficiency.
