A Proposal of Description Logic on Concept Lattices
There are two major formalisms that are developed around concepts: (1) Formal Concept Analysis (FCA) by R. Wille and B. Ganter, and (2) Description Logic (DL) that goes back to the...

Evolutionary Clustering in Description Logics: Controlling Concept Formation and Drift in Ontologies
Abstract. We present a method based on clustering techniques to detect concept drift or novelty in a knowledge base expressed in Description Logics. The method exploits an effectiv...

Nominal Schemas for Integrating Rules and Description Logics
We propose an extension of SROIQ with nominal schemas which can be used like “variable nominal concepts” within axioms. This feature allows us to express arbitrary DL-safe rule...
