Cyc

CYC is like a giant brain that holds lots of information about the world, and it helps other computers understand and make sense of things. It's kind of like a smart encyclopedia that knows about everything! Imagine you have a big book with all the answers to every question you could ever ask. CYC is kinda like that, except it's not in one book, but it's in a computer that can think like a person. It can tell you about who a person is, what they like, what they do, and what things are related to each other. It's like having a smart friend you can ask for help whenever you need to understand something.
