Translation of Ontology Retrieval Problem into Relational Queries

By Jana Pribolová

Abstract

Abstract. Ontology as a knowledge base can provide different reasoning tasks, e.g. to check consistency of the ontology or to check whether a resource is instance of a concept or not. In this paper we want to focus on retrieval problem. There already exist systems resolving this problem, but they are not effective within large datasets. Our idea is to transform ontology into a relational database. We present particular algorithms of this transformation both on the scheme level and SQL level with special handling of functional roles and definitions. This enables to query such database by usual tools of SQL, i.e. to solve the retrieval problem
