![]() ![]() ![]() The more expressive a KR, the easier and more compact it is to express a fact or element of knowledge within the semantics and grammar of that KR. These elements – symbols, operators, and interpretation theory – are what give sequences of symbols meaning within a KR.Ī key parameter in choosing or creating a KR is its expressivity. Examples of operators and operations include negation, conjunction, adverbs, adjectives, quantifiers and modal operators. Logic is also used to define how operators can process and reshape the knowledge. Logic is used to supply formal semantics of how reasoning functions should be applied to the symbols in the KR system. A symbol vocabulary and a system of logic are combined to enable inferences about elements in the KR to create new KR sentences. Knowledge representation (KR) research involves analysis of how to reason accurately and effectively and how best to use a set of symbols to represent a set of facts within a knowledge domain. 4.3.1 Commitment begins with the earliest choices.4.2 Knowledge Representation Hypothesis.
