Membership Function Assignment for Elements of Single OWL Ontology

TL;DR

This paper proposes a method for assigning membership functions to elements of a single OWL ontology to facilitate the generation of fuzzy rules, enhancing the capabilities of the Semantic Web Expert System.

Contribution

It introduces a novel approach for membership function assignment in single OWL ontologies, expanding beyond previous methods focused on merged ontologies.

Findings

Enables generation of fuzzy rules from single OWL ontologies

Supports the development of a more versatile Semantic Web Expert System

Improves knowledge extraction from OWL ontologies in the Web

Abstract

This paper develops the idea of membership function assignment for OWL (Web Ontology Language) ontology elements in order to subsequently generate fuzzy rules from this ontology. The task of membership function assignment for OWL ontology elements had already been partially described, but this concerned the case, when several OWL ontologies of the same domain were available, and they were merged into a single ontology. The purpose of this paper is to present the way of membership function assignment for OWL ontology elements in the case, when there is the only one available ontology. Fuzzy rules, generated from the OWL ontology, are necessary for supplement of the SWES (Semantic Web Expert System) knowledge base. SWES is an expert system, which will be able to extract knowledge from OWL ontologies, found in the Web, and will serve as a universal expert for the user.
