The classical description logic SHOIN, as the logical foundation of OWL DL, is less suitable to represent fuzzy knowledge in the Semantic Web. We introduce cut concepts and cut roles to SHOIN, and present extended fuzzy description logic EFSHOIN. We define the representation of EFSHOIN, and focus on the knowledge base consistency as main reasoning task. We also propose a reasoning algorithm for the...
UML is a standard for object-oriented modeling. Since the majority of real world information is uncertain and vague, fuzzy UML has been presented. Analogous to UML, fuzzy UML is semi-formed. In order to solve this problem, this paper attempts to formalize fuzzy UML class diagrams with fuzzy description logics, mainly with focus on formalization of elements in fuzzy UML class diagram and applying this...
The fuzzy ontologies play a key role in the semantic Web. The description logic SHOIN, the logical foundation of Web ontology language OWL, becomes less suitable to describe them. To represent fuzzy ontologies, this paper presents the extended fuzzy description logic EFSHOIN, shows the representation and reasoning capabilities of EFSHOIN, and proposes a tableau algorithm for the consistency of EFSHOIN...
