Ontology matching

Ontology matching is like when you try to match two things that are similar but not exactly the same. It's like if you have two pictures of the same thing. You look at both pictures to see how they are the same and how they are different. Ontology matching is a way to try and match two different versions of the same thing. Computers can do it and people can do it. It helps them understand the different versions so they can be used together, like if they need to communicate with each other.
