On the Problem of Weighted Max-DL-SAT and its Application to Image Labeling
Abstract. For a number of problems, such as ontology learning or image labeling, we need to handle uncertainty and inconsistencies in an appropriate way. Fuzzy and Probabilistic De...

Dependencies to Optimize Ontology Based Data Access
Query answering in Ontology Based Data Access (OBDA) exploits the knowledge of an ontology’s TBox to deal with incompleteness of the ABox (or data source). Current query-answerin...

Correcting Access Restrictions to a Consequence More Flexibly
Recent research has shown that labeling ontologies can be useful for restricting the access to some of the axioms and their implicit consequences. However, the labeling of the axio...

Two-Dimensional Description Logics of Context
We introduce an extension of Description Logics (DLs) for representing and reasoning about contextualized knowledge. Our formalism is inspired by McCarthy’s theory of formalizing...

On P/NP Dichotomies for EL Subsumption under Relational Constraints
Abstract. We consider the problem of characterising relational constraints under which TBox reasoning in EL is tractable. We obtain P vs. coNP-hardness dichotomies for tabular cons...
