Abstract:
Constructive description logics provide different interpretations of description logics under constructive semantics. While several constructive semantics for description logics have been proposed, such logics have been mostly studied from the point of view of their formal properties. Practical applications of these logics have been proposed, but there has been no effort in applying them in general in knowledge representation and Semantic Web languages and tools (i.e., the distinctive applications of description logics). In our recent work, we started to address this aspect: we introduced a constructive semantics for the description logic EL and we established formal results that link this constructive interpretation to answer set semantics. On the base of these results, we presented a datalog translation reasoning on one aspect of such semantics (the generation of information terms of a knowledge base) and an implementation using Semantic Web ontologies and "off the shelf" tools. In this paper, we want to highlight this line of research and its possibilities and the challenges in extending this work to more expressive description logics.
