Inconsistency Handling in Prioritized Databases with Universal Constraints: Complexity Analysis and Links with Active Integrity Constraints
Meghyn Bienvenu, Camille Bourgaux
This paper revisits the problem of repairing and querying inconsistent databases equipped with universal constraints. We adopt symmetric difference repairs, in which both deletions…
Revisiting Semiring Provenance for Datalog
Camille Bourgaux, Pierre Bourhis, Liat Peterfreund +1
Data provenance consists in bookkeeping meta information during query evaluation, in order to enrich query results with their trust level, likelihood, evaluation cost, and more. Th…
Querying Inconsistent Prioritized Data with ORBITS: Algorithms, Implementation, and Experiments
Meghyn Bienvenu, Camille Bourgaux
We investigate practical algorithms for inconsistency-tolerant query answering over prioritized knowledge bases, which consist of a logical theory, a set of facts, and a priority r…
Geometric Models for (Temporally) Attributed Description Logics
Camille Bourgaux, Ana Ozaki, Jeff Z. Pan
In the search for knowledge graph embeddings that could capture ontological knowledge, geometric models of existential rules have been recently introduced. It has been shown that c…
Capturing Homomorphism-Closed Decidable Queries with Existential Rules
Camille Bourgaux, David Carral, Markus Krötzsch +2
Existential rules are a very popular ontology-mediated query language for which the chase represents a generic computational approach for query answering. It is straightforward tha…
Querying and Repairing Inconsistent Prioritized Knowledge Bases: Complexity Analysis and Links with Abstract Argumentation
Meghyn Bienvenu, Camille Bourgaux
In this paper, we explore the issue of inconsistency handling over prioritized knowledge bases (KBs), which consist of an ontology, a set of facts, and a priority relation between…
Provenance for the Description Logic ELHr
Camille Bourgaux, Ana Ozaki, Rafael Peñaloza +1
We address the problem of handling provenance information in ELHr ontologies. We consider a setting recently introduced for ontology-based data access, based on semirings and exten…
