Logic is the study of correct reasoning. It includes both formal and informal logic. Formal logic is the science of deductively valid inferences or logical truths. It studies how conclusions follow from premises due to the structure of arguments alone, independent of their topic and content.

– Description logics are formal languages designed for knowledge representation and. reasoning, and most of these are decidable fragments of FOL. – Each description logic describes a language, and each language differ in. expressibility vs.

Description logic is a formalism used in AI applications for representing and reasoning about the properties of concepts and individuals. It is closely related to first-order logic, but with a more restricted syntax that makes it more suitable for automated reasoning.

DLs are used in artificial intelligence to describe and reason about the relevant concepts of an application domain (known as terminological knowledge). It is of particular importance in providing a logical formalism for ontologies and the Semantic Web: the Web Ontology Language (OWL) and its profiles are based on DLs.

There are general, spatial, temporal, spatiotemporal, and fuzzy description logics, and each description logic features a different balance between expressive power and reasoning complexity by supporting different sets of mathematical constructors.

Logical AI involves representing knowledge of an agent's world, its goals and the current situation by sentences in logic. The agent decides what to do by inferring that a certain action or course of action is appropriate to achieve the goals.
