Fuzzy description logics under Gödel semantics
Classical ontologies are not suitable to represent vague pieces of information, which has lead to the birth of Fuzzy Description Logics as an appropriate formalism to represent this type of knowledge. Different families of fuzzy operators lead to Fuzzy Description Logics with different properties. This paper studies Fuzzy Description Logics under a semantics given by the Gödel family of fuzzy o...
متن کاملReasoning in Expressive Description Logics under Infinitely Valued Gödel Semantics
Fuzzy Description Logics (FDLs) combine classical Description Logics with the semantics of Fuzzy Logics in order to represent and reason with vague knowledge. Most FDLs using truth values from the interval [0, 1] have been shown to be undecidable in the presence of a negation constructor and general concept inclusions. One exception are those FDLs whose semantics is based on the infinitely valu...
متن کاملJoining Gödel and Zadeh Fuzzy Logics in Fuzzy Description Logics
Ontologies have succeeded as a knowledge representation formalism in many domains of application. Nevertheless, they are not suitable to represent vague or imprecise information. To overcome this limitation, several extensions to classical ontologies based on fuzzy logic have been proposed. Even though different fuzzy logics lead to fuzzy ontologies with very different logical properties, the c...
متن کاملAlgorithms for reasoning in very expressive description logics under infinitely valued Gödel semantics
Fuzzy description logics (FDLs) are knowledge representation formalisms capable of dealing with impreciseknowledge by allowing intermediate membership degrees in the interpretation of concepts and roles. Oneoption for dealing with these intermediate degrees is to use the so-called Gödel semantics, under whichconjunction is interpreted by the minimum of the degrees of the conjuncts. ...
متن کاملProbabilistic Description Logics under the distribution semantics
Representing uncertain information is crucial for modeling real world domains. In this paper we present a technique for the integration of probabilistic information in Description Logics (DLs) that is based on the distribution semantics for probabilistic logic programs. In the resulting approach, that we called DISPONTE, the axioms of a probabilistic knowledge base (KB) can be annotated with a ...
