Abstract: 
We study the usefulness of dl-programs in implementing Reiter's default logic on top of a Description Logic knowledge base (DL-KB). To this end, we investigate transformations from default theories to description logic programs (dl-programs) based on different established algorithms for computing default theory extensions, namely select-defaults-and-check and select-justifications-and-check algorithm.
In each transformation, additional constraints are exploited to prune the search space based on conclusion-conclusion or conclusion-justification relations. The implementation was deployed as a new component for the dl-plugin for dlvhex, and evaluated with various experimental test ontologies, which showed promising results.
