Natural Language Processing
📋 What it is
NLP lets AI work with human language — translating, summarising, and powering chatbots.
🗣️ Coach says
Natural Language Processing (NLP) is AI for words. It powers translation, voice assistants, autocomplete, and chatbots. Modern language AI is trained on enormous amounts of text and predicts likely word sequences — which is why it can sound fluent, but also why it can confidently make things up.
🧠 Memory hook
NLP = AI for language (translate, summarise, chatbots). Predicts likely words — fluent, but can make things up.
😂 Giggle
What did one neuron say to the other?
"I'm feeling a strong connection!"
😲 Whoa!
AI language translators now handle over 100 languages and translate billions of words a day — but they still stumble on jokes, idioms and sarcasm.
✅ Quick check: Why can an AI chatbot sound fluent yet still be wrong?
Say your answer out loud first — then reveal.
It predicts likely word sequences from training text; sounding right isn’t the same as being factually correct.
Language models optimise fluency/likelihood, not truth.
