Evolution of ontology potential for generation of rules

Abstract

The main purpose of this paper is to evaluate the potential of OWL (Web Ontology Language) ontologies for generation of rules. It is assumed that OWL ontology expressions can serve as a material for rule extraction. It is necessary for Semantic Web Expert System development and it is expected that such Semantic Web Expert System (SWES) will be able to process ontologies from the Web with the purpose to supplement or even to develop its knowledge base. Available publications show that the problem of rule extraction from ontologies is not investigated deeply enough.

Algorithm of Ontology Transformation to Concept Map for Usage in Semantic Web Expert System

“…To develop the structure of the concept map, we should recall all seven kinds of OWL ontology transformations to rules [2]. In the first case, when class is not empty it can serve as a source for rule generation.…”

“…In the first case, when class is not empty it can serve as a source for rule generation. For instance, if there is "Arrhythmia" class with three properties P1, P2, P3, then it becomes possible to generate the following rule [2]: IF P1 and P2 and P3 THEN Arrhythmia (1) In the second case there are two equivalent classes [2]. For example, there is "Arrhythmia" class and class "A" which is equivalent to class "Arrhythmia".…”

For example, there are "Son" and "Father" classes and also the "hasParent" relation between these two classes.…”
