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, the authors want to focus on retrieval problem. There already exist systems resolving this problem, but they are not effective within large datasets. Their idea is to transform ontology into a relational database. They present particular algorithms of this transformation both on the scheme level and SQL (Structured Query Language) level with special handling of functional roles and definitions.
