The axis labeling in figure 8 is unintelligible if, as you mention, the values are to be understood as lg(error) = ~25. Another issue in the evaluation is the (somewhat suspicious) use of a subset of SwetoDBLP that has only ~0.8 edges for every node (which seems like it might lead to a somewhat uninteresting graph). t lead to a somewhat uninteresting graph). |

How is it that MD-Tree estimated a frequency that deviated from the actually frequency by about 33.5x10^6 when there aren't even that many nodes or edges in the SwetoDBLP dataset? (or did I read something wrong?) In Figures 8g-h, the worst case for P-Tree is similar and on an even smaller dataset (TOntoGen). and on an even smaller dataset (TOntoGen). |
