We now know that the addition of a concept constructor called a Path Functional Dependency (PFD) to the Boolean-complete description logic DLF leads to undecidability of ABox consi...
Fuzzy Description Logics (Fuzzy DLs) and fuzzy OWL have been proposed as languages able to represent and reason about imprecise and vague knowledge. Such extensions have gained con...
Abstract. This paper investigates Description Logics which allow transitive closure of roles to occur not only in concept inclusion axioms but also in role inclusion axioms. First,...
The paper presents an unified Description Logic (DL) model for databases. Describing database models using DLs is a fundamental problem in many areas because it turns databases to...
