Description Logic
Description Logic (DL) is a formal framework used to represent and reason about knowledge, particularly in structured domains like semantic web and artificial intelligence. It allows for defining concepts, relationships, and individuals in a precise way. DL extends modal logic by incorporating descriptions of classes and properties, enabling the creation of complex systems of knowledge. For instance, it can specify that "all birds can fly" while allowing for exceptions like penguins. By using Description Logic, we can efficiently infer new information, verify consistency, and facilitate automated reasoning in various applications, including ontology development and knowledge representation.
