Description logic

Description logic is a type of logic used in artificial intelligence and computer science to describe objects. It uses symbols to represent things and relationships between them. For example, the symbol “A” could stand for an apple and the symbol “B” could stand for a banana. If we want to express the fact that an apple is a type of fruit, we could write “A ⇒ F”, meaning that “A" is a type of “F”, which stands for fruit. Description logic can also be used to describe complex relationships between objects, such as how two objects may relate to each other, or how two different properties go together.
