KurzfassungAbstract
We consider a logical diff operator and semantic module extraction from ontologies. In recent work, we have shown that, for the fragment EL of OWL, these problems can be solved in polynomial time. In this paper, we evaluate our algorithms by experimenting with the prototype implementations CEX and MEX on real-worlds ontologies such as SNOMED. The experiments show the practicability our approach and highlight the benefits of a strictly semantic approach: the diff operation is very fine-grained and the extracted modules are smaller than the ones generated by related approaches.
