What this unit is about
Natural Language Processing (NLP) is the domain of AI that helps computers understand and use human language, in text or speech.
1. How machines process text
To understand text, a machine breaks it into words, called tokenisation. It removes very common words (stopwords) and counts the important ones, an idea called the bag of words.
2. Chatbots
A chatbot is a program you can chat with. It reads your message with NLP and gives a helpful reply. Voice assistants work the same way with speech.
3. Uses and challenges
NLP powers chatbots, translation, voice assistants and spam filters. Language is hard because words have many meanings and context matters, so NLP keeps improving.
