Semantic interoperability is like sharing toys with your friends. You know that everyone has a different toy with different shapes, sizes, and colors. But you all agree on the names of each toy. You know that a toy car is called a car, and a toy train is called a train, and so on.
In the same way, semantic interoperability is when different computer systems can talk to each other and understand what each other means, even if they are using different words or languages. It's like when you and your friends use the same toy names to play together, even if you are speaking different languages.
So, when different computer systems have semantic interoperability, they can share information and work together easily. This is important in many fields like healthcare, finance, and government where different organizations need to share data to make decisions and provide services.
