Paper Abstract

A set theoratical model for representing pattern and pattern classes was previously proposed (Gokeri, 1983). In this paper a method for matching the semantic net model of a given pattern with the elements of a set of pattern class models is proposed. Accordingly, for a pattern class a new mathematical model, M, is defined such that M=<P,ψ>, P is a semantic net defining the pattern class and ψ:PxP →[0,1] is a probability function. ψ(fi,fj) may be interpreted as the conditional probability of occurrence of feature Fi with given Fj. Using these values and an empirically developed decision function, Δ , a .1 measure of simiiarity between the model of a pattern class and model of a sample pattern is determined. The Δ- function returns a scalar value in the interval [-1, 1] such that positive values signify similarity. If A=0, no decision can be made regarding the degree of semblance between two semantic net models, and negative values of A indicate no likeness. Finally, a method for modifying the decision function is offered.
