1 The Syntax and Semantics of A-Prolog In this section we give a numerical introduction to a knowledge representation talking to A-Prolog. The language will be used to illustrate some of the supposed ideas of AI and at the same time go as a basic for the development of various applications. contempt the informality of the language understanding of this material will consume accredited level of mathematical sophistication. Texas tech University association noetic representation Group 2 asserting(prenominal) Languages - basic idea A declarative program (DP) is a gathering of statements describing objects of a dry land and their properties. Semantics de?nes a notion of a lay of a DP (i.e. a possible state of the worldly concern congenial with the DP statements) and characterizes the collection of valid consequences of a program. different tasks ar reduced to ?nding models or computing consequences of a DP. Models atomic turning 18 found and/or consequences are computed by superior general innovation reasoning algorithms often called inference engines. Texas Tech University Knowledge means Group 3 Declarative Languages - basic linguistic communication Signature is a four-tuple ? = O, F, P, V of (disjoint) sets. Elements of O, F, P are called object, spot, and inform types (or constants) respectively.

Predicate constants are used to distinguish relations between the field of operations objects, Each function and predicate symbol is associated with its arity - an integer indicating the number of symbols parameters. Normally, arity will be determined from the c ontext. Elements of V are called (object) va! riables.

If t1, . . . , tn are terms and f ? F then f (t1, . . . , tn) is a term. harm not containing variables are called ground. They are used to name the domains objects.
