Reasoning and Quantification in Fuzzy Description Logics
2006In this paper we introduce reasoning procedures for $\mathcal{ALCQ}^{+}_{F}$, a fuzzy description logic with extended qualified quantification. The language allows for the definition of fuzzy quantifiers of the absolute and relative kind by means of piecewise linear functions on ℕ and ℚ∩[0,1] respectively.

A family of Extended Fuzzy Description Logics
International Journal of Business Intelligence and Data Mining, 2006Typical description logics are limited to dealing with crisp concepts and crisp roles. However, web applications based on description logics should allow the treatment of the inherent uncertainty. Extended Fuzzy Description Logics (EFDLs), which adopt a special fuzzify-method with more expressive power than the previous fuzzy description logics, are ...

How to enrich description logics with fuzziness
2017 Computing Conference, 2017The paper describes the relation between fuzzy and non-fuzzy description logics. It gives an overview about current research in these areas and describes the difference between tasks for description logics and fuzzy logics. The paper also deals with the transformation properties of description logics to fuzzy logics and backwards.

Extended Fuzzy Description Logic ALCN
2005Web applications based on description logics often need management of fuzzy information and encounter fuzzy concepts. This paper proposes an extended fuzzy ALCN to enable representation and reasoning for complex fuzzy information. The extended fuzzy ALCN introduces the cut sets of fuzzy concepts and fuzzy roles as atomic concepts and atomic roles, and ...

Introducing Fuzzy Temporal Description Logic
Proceedings of the 3rd International Conference on Industrial and Business Engineering, 2017Description logics are considered as the logical infrastructure of knowledge representation on the semantic Web as well as information systems. To deal with imprecise temporal knowledge and its applications, we introduce a fuzzy temporal description logic (FTDL) in which such temporal is characterized in a classic description logic.

Extending OWL by fuzzy description logic
17th IEEE International Conference on Tools with Artificial Intelligence (ICTAI'05), 2005Technology about ontology plays an important role in all kinds of technologies about the semantic Web. OWL, the standard Web ontology language is proposed by W3C. Vocabularies in OWL only represent certain and complete concepts and roles. In order to represent fuzzy knowledge, this paper extends existing OWL language by encoding fuzzy constructors ...

A Distributed and Fuzzy Extension of Description Logics
2006By development of the Semantic Web, demands for increasing expressive power of ontology languages has triggered a mass of extending description logics in fuzzy and distributed cases. However, current solutions are proposed respectively on one of these two aspects.

From classical Description Logic to n-graded Fuzzy Description Logic
International Conference on Fuzzy Systems, 2010Description Logics (DLs) are knowledge representation languages built on the basis of classical logic. DLs allow the creation of knowledge bases and provide ways to reason on the contents of these bases. Fuzzy Description Logics (FDLs) are natural extensions of DLs for dealing with vague concepts, commonly present in real applications.
