- Question is for the Presentation: Joshua Taylor 20080918 Presentation
- Question is asked by: Joshua Taylor
- The Question is: Quoth the first paragraph of Section 6 "Empirical Evaluation", "Our system implements a slightly more simplistic procedure than the one in Algorithm 2; in particular, once the affected modules have been identifies, our implementation simply reclassifies the union of these modules using Pellet to determine the new subsumption relations, instead of using the procedure described in lines 20–34 of Algorithm 2." Does this have any significant effect on the results?
Answer
Joshua Taylor answered, While what the authors actually did was a simplification compared to what was presented in Algorithm 2, it would probably more computationally complex to do what was actually specified. That is, when Pellet computes a classification it probably has to compute a classification for an entire ontology. In any case, to check some particular subsumption, it almost certainly computes some other subsumptions at the same time. Thus it will be more efficient to simply classify the union of the modules (as a single ontology) than to compute each subsumption individually.
