properties of knowledge representation in ai

By in

Abstract. Updating the state requires the information about − A knowledge representation system should have following properties. Properties for knowledge Representation. Knowledge Representation is a radical and new approach in AI … The representation and manipulation of knowledge has been drawing a great deal of attention since the early days of computer science, resulting in the introduction of numerous different Knowledge Representation schemes (KR-schemes). Knowledge representation plays a role in setting up the environment and gives all the details necessary to the system. Syntax The syntax of a language defines which configurations of the components Internal State − It is a representation of unobserved aspects of current state depending on percept history. Use of Knowledge Representation in AI Systems The role of knowledge representation in AI systems can be understood by looking at the methodology followed by AI systems. Properties of Representation Systems 4 Representational adequacy – ability to represent the required knowledge Inferential adequacy – ability to manipulate knowledge ⇒ produce new knowledge Inferential efficiency – ability to direct inference methods into productive directions – ability to respond with limited resources (time, storage) Table displays the knowledge for the zoo animals problem in two formats–using rules on the left as implemented within the Knowledge Representation … Levesque H, Brachman R, A fundamental tradeoff in knowledge representation and reasoning, reprinted in Readings in Knowledge Representation, pp. The classic methods of representing knowledge use either rules or logic. ), Edinburgh: Edinburgh University Press, pp. It has to do with the ‘thinking’ of AI systems and contributes to its intelligent behavior. In artificial intelligence, knowledge representation is the study of how the beliefs, intentions, and value judgments of an intelligent agent can be expressed in a transparent, symbolic notation suitable for automated reasoning. Perception block [16] McCarthy J, Hayes P, Some philosophical problems from the standpoint of AI, in Machine Intelligence 4 , Meltzer and Michie (eds. The process is as follows: 1. 42-70. A knowledge representation language is defined by two aspects: 1. Representing Knowledge using rules in AI. Ernest Davis, in International Encyclopedia of the Social & Behavioral Sciences (Second Edition), 2015. Given the great variety of such available schemes, it would be desirable to have a uniform way of treating them. Model − knowledge about “how the things happen in the world”. A good knowledge representation system must have following properties: a) Representation Adequacy: It must be able to represent all knowledge required in a particular domain b) Inferential Adequacy: It must be able to derive knowledge representation structures such as symbols when new knowledge is inferred from old knowledge A good knowledge representation enables fast and accurate access to knowledge and understanding of the content. The following properties should be possessed by a knowledge representation system. 463-504, 1969. Knowledge representation and reasoning (KR², KR&R) is the field of artificial intelligence (AI) dedicated to representing information about the world in a form that a computer system can utilize to solve complex tasks such as diagnosing a medical condition or having a dialog in a natural language.Knowledge representation incorporates findings from psychology about how humans solve … What is a Knowledge Representation? Representational Adequacy The ability to representall kinds of knowledge that are needed in that domain. The object of a knowledge representation is to express knowledge in a computer tractable form, so that it can be used to enable our AI agents to perform well. a. Representational Adequacy: It is the ability to represent the required knowledge.
