Fuzzy-temporal database ontology and relational database model

摘要

This paper presents ontology for temporal and fuzzy information representation in the context of relational database environment. Temporal information has its own semantics and there are approaches to deal with representation of temporal data in different database environments. Temporal data may not be precise or crisp in nature, there is an element of imprecision or vagueness in representing temporal attributes. This paper proposes general model for temporal and fuzzy ontology for building fuzzy-temporal database schema with illustrations.
