YAGO (database)

Yago is like a huge book that has information about many things, such as people, places, animals, and even ideas. But it's not just any book; it's a special kind of book that computers can read and understand. This means that people can ask questions to the computer, and it can look up the answers in the Yago book.

For example, if you ask a computer, "Who is Barack Obama?" the computer can use Yago to tell you that Barack Obama is a person who used to be the president of the United States. Or if you ask, "What is a giraffe?" the computer can use Yago to tell you that a giraffe is a tall animal with a long neck that lives in Africa.

But the Yago book has even more information than just that! It also tells us how different things are related to each other, like how Barack Obama is related to other people or events, or how a giraffe is related to other animals. This is called "semantic information," which means information about the meaning and relationships between things.

So, in summary, Yago is a really big computer book that has information about all kinds of things, and it helps computers answer questions and understand how different things are related to each other.
