DpUE� 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 … CS 2740 Knowledge representation M. Hauskrecht Knowledge representation CS 2740 Knowledge representation M. Hauskrecht Artificial Intelligence • The field of Artificial intelligence: – The design and study of computer systems that behave intelligently • AI programs: – Go beyond numerical computations and manipulations Hence we can describe Knowledge representation as following: Knowledge representation and reasoning (KR, KRR) is the part of Artificial intelligence which concerned with AI agents thinking and how thinking contributes to intelligent behavior of agents. Knowledge engineering is one of the building blocks of artificial intelligence (AI). Knowledge • A declarative representation is one in which knowldge is specified, but the use to which that knowledge is to be put is not given • A procedural representation is one in which the control information that is necessary to use the knowledge is considered to be embedded in the knowledge itself. <> E.g., Russell and Norvig's, Artificial Intelligence: A Modern Approach . 5 0 obj Goal Based Agents Semantic nets convey meaning.

Artificial Intelligence (AI) is the ability for an artificial machine to act intelligently. In 2006 [24], the link between object assessment tracking and situation assessment was discussed which focused on knowledge representation. From the computer system point of view, the representation must be efficient. The most common answer that one expects is “to make computers intelligent so that they can act intelligently!”, but the question is how much intelligent? Forward chaining and backward chaining In a rule-based expert system, the domain knowledge is represented by a set of IF-THEN production rules and data is represented by a … Get hold of all the important CS Theory concepts for SDE interviews with the CS Theory Course at a student-friendly price and become industry ready.
