    • Repairing Ontologies via Axiom Weakening 

      Troquard N; Confalonieri R; Galliani P; Peñaloza R; Porello D; Kutz O (AAAI press, 2018)
      Ontology engineering is a hard and error-prone task, in which small changes may lead to errors, or even produce an inconsistent ontology. As ontologies grow in size, the need for automated methods for repairing inconsistencies ...
    • Repairing Socially Aggregated Ontologies Using Axiom Weakening 

      Porello D; Troquard N; Confalonieri R; Galliani P; Kutz O; Peñaloza R (Springer, 2017)
      Ontologies represent principled, formalised descriptions of agents’ conceptualisations of a domain. For a community of agents, these descriptions may significantly differ. We propose an aggregative view of the integration ...
    • Two applications of concept refinement 

      Confalonieri R; Troquard N; Galliani P; Kutz O; Peñaloza R; Porello D (CEUR-WS, 2018)
      We describe two applications of refinement operators that can generalise and specialise concepts expressed in the ALC description logic language. The first application addresses the problem of analysing the joint coherence ...
    • Two Approaches to Ontology Aggregation Based on Axiom Weakening 

      Porello D; Troquard N; Peñaloza R; Confalonieri R; Galliani P; Kutz O (IJCAI, 2018)
      Axiom weakening is a novel technique that allows for fine-grained repair of inconsistent ontologies. In a multi-agent setting, integrating ontologies corresponding to multiple agents may lead to inconsistencies. Such ...
