Abstract

Errors in Description Logic (DL) ontologies are often detected when a reasoner computes unwanted consequences. The question is then how to repair the ontology such that the unwanted consequences no longer follow, but as many of the other consequences as possible are preserved. The problem of computing such optimal repairs was addressed in our previous work in the setting where the data (expressed by an ABox) may contain errors, but the schema (expressed by an \(\mathcal {EL} \) TBox) is assumed to be correct. Actually, we consider a generalization of ABoxes called quantified ABoxes (qABoxes) both as input for and as result of the repair process. Using qABoxes for repair allows us to retain more information, but the disadvantage is that standard DL systems do not accept qABoxes as input. This raises the question, investigated in the present paper, whether and how one can obtain optimal repairs if one restricts the output of the repair process to being ABoxes. In general, such optimal ABox repairs need not exist. Our main contribution is that we show how to decide the existence of optimal ABox repairs in exponential time, and how to compute all such repairs in case they exist.

Notes

  1. 1.

    https://www.w3.org/OWL/.

  2. 2.

    For example, the large medical ontology Snomed CT is an \(\mathcal {EL} \) ontology.

  3. 3.

    The proof for this polynomiality result in [20] is actually incorrect, but we show how to correct it.

  4. 4.

    The variables correspond to what we have called anonymized individuals in the introduction, and the individuals to what we have called named individuals.

  5. 5.

    The \(\mathsf {IQ}\)-repairs computed by the approaches in [3] would contain more assertions, which are however redundant for \(\mathsf {IRQ}\)-entailment w.r.t. \(\mathcal {T}\).
