[SWC] representational issues in combining rules and ontologies

Dear all,

We've just concluded a study into some of the representational issues
which arise when combining rules and ontologies. This might be of
interest to this working group:

Abstract:

In the context of current efforts around Semantic-Web languages, the
combination of classical theories in classical first-order logic (and in
particular of ontologies in various description logics) with rule
languages rooted in logic programming is receiving considerable
attention. Existing approaches such as SWRL, dl-programs, and DL+log,
differ significantly in the way ontologies interact with (nonmonotonic)
rules bases. In this paper, we identify fundamental representational
issues which need to be addressed by such combinations and formulate a
number of formal principles which help to characterize and classify
existing and possible future approaches to the combination of rules and
classical theories. We use the formal principles to explicate the
underlying assumptions of current approaches. Finally, we propose a
number of settings, based on our analysis of the representational issues
and the fundamental principles underlying current approaches.



Best, Jos
