Knowledge Representation Approaches in Artificial Intelligence

Knowledge representation (KR) is the study of how knowledge and facts about the world can be represented, and what kinds of reasoning can be done with that knowledge. It is a medium for pragmatically efficient computation, and the computational environment in which thinking is accomplished. The knowledge representation is used to solve the problems encountered in artificial intelligence. KR is a field of artificial intelligence that focuses on designing computer representations that capture information about the world that can be used to solve complex problems. Knowledge representation techniques support the representation of knowledge in a structured form which is suitable for computer processing. Todays knowledge representation system requires to design a general system which is applicable to represent declarative as well as procedural knowledge.
