Natural Language Processing


Natural Language Processing (NLP) falls under the fields of computer science, linguistics, and artificial intelligence. NLP deals with how computers understand, process, and manipulate human languages. It can involve things like interpreting the semantic meaning of language, translating between human languages, or recognizing patterns in human languages. It makes use of statistical methods, machine learning, neural networks and text mining. 


Google Translate uses some of the most advanced NLP tools available. Automated Chatbots, text predictors, and speech to text applications also use forms of NLP.
