| Abstract [eng] |
Ontologies are becoming increasingly popular because they allow organizations to describe their problem domains in a more flexible manner and to search information from multiple sources giving semantically significant results for users. However, the increasing amount of information in ontology makes its storing in a text file not effective. The aim of this research is to improve possibilities of querying large ontologies when these are kept in relational databases. The method was created for executing SPARQL queries in ontology, stored in a relational database created by OWL2RDB algorithm. Experiments have shown that the method improves query performance time in comparison with existing query engine especially for large ontologies having many individuals. |
