Question is for the Presentation: Theoharis2008graph presented by Tim Lebo 4 dec 2008
Question is asked by: Gregory Todd Williams
The Question is: Section 4C(3), Distribution of Class Levels, states that a class c has level 0 if it is the root, and p+0 where p is the level of its parent otherwise. However, it goes on to say "if c has more than one parents, then p is the maximum of their levels" and also "The biggest number of classes is observed between the middle and the maximum leaf level." Isn't this latter observation strongly suggested by the former stated preference of the maximum level of multi-parented classes? Does this choice affect the results? Is any indication given of the frequency of multi-parented classes in the analyzed schemas?
