Hi Doug,
Thanks for your detailed reply. Regarding your questions on count1, coun12, intersection here is some info.
In the Jaccard similarity code item1 and item2 refer to Entity1 and Entity2 .
Count1 gives the total number of Processes associated with a given Entity. Example: Entity " Adjudication Outcome Option" has access to 20 Processes.
Count2 is same as Count1 except for the second Entity.
Intersection is the Processes that are shared between two Entities. In the second picture above you can see (in the center) 10 Processes shared by two Entities.
Similarity = (number of shared processes) / (total number of distinct processes) and in this case it is (10/30) = .333
Hope this answers your questions.
