Dealing with Similarity Relations in Fuzzy Ontologies

Afef Bahri, Rafik Bouaziz, Faiez Gargouri
2007 IEEE International Fuzzy Systems conference proceedings  
Crisp ontologies become less suitable in all domains in which the concepts to be represented have vague, uncertain and imprecise definitions.  ...  The latter approach needs to be dealt with differently in crisp and fuzzy ontologies. This is the scope of this paper.  ...  The conjunction, disjunction and negation of fuzzy sets can be easily applied to the interpretation of fuzzy concepts.  ...
