Storing fuzzy ontology in fuzzy relational database

Abstract

Information imprecision and uncertainty exist in many real-world applications and for this reason fuzzy ontologies have been extensively investigated and increasingly created. Therefore, it is critical to develop scalable and efficient fuzzy ontology storage mechanism. The fuzzy relational database may be a good candidate for storing fuzzy ontologies because of the widespread use and mature techniques. In this paper, we propose an approach for storing fuzzy ontologies in fuzzy relational databases. The elements of fuzzy ontologies are introduced first, where most of constructors of fuzzy ontologies are considered. On this basis, we propose an approach for storing all of these elements of fuzzy ontologies in fuzzy relational databases, and an example is provided throughout the paper to well explain the approach. © 2011 Springer-Verlag Berlin Heidelberg.
