Marco Cerami, Umberto Straccia
Recently there have been some unexpected results concerning Fuzzy Description Logics (FDLs) with General Concept Inclusions (GCIs). They show that, unlike the classical case, the D…

Reasoning within Fuzzy Description Logics
U. Straccia
Description Logics (DLs) are suitable, well-known, logics for managing structured knowledge. They allow reasoning about individuals and well defined concepts, i.e., set of individu…
A General Framework for Representing, Reasoning and Querying with Annotated Semantic Web Data
Antoine Zimmermann, Nuno Lopes, Axel Polleres +1
We describe a generic framework for representing and reasoning with annotated Semantic Web data, a task becoming more important with the recent increased amount of inconsistent and…
On the relationship between fuzzy logic and four-valued relevance logic
Umberto Straccia
In fuzzy propositional logic, to a proposition a partial truth in [0,1] is assigned. It is well known that under certain circumstances, fuzzy logic collapses to classical logic. In…
