How long does it take for you to learn English? How could you know that Apple can mean a fruit and not the company which designs iPhone. Imagine how you could teach a young child that Apple can either mean a fruit or a brand. How about teaching a computer? That's exactly what this book is about.

You'll discover how AI figures out that two completely different sentences, \"I love to eat Apple\" and \"Apple designs iPhone\" can lead to different meanings for the same word, \"Apple\". We start with something as simple as counting words, then gently build up to the same powerful technique used inside today's advanced AI systems — with clear, friendly explanations at every step.

Along the way, you'll see why understanding sentence similarity is at the heart of everything from AI Search to AI Chatbots and AI Agents. By the last page, you'll see the world of AI differently — and realise that understanding AI begins with something as simple as counting words.
