(Solved) : Given Following Query Q Data Graph G Au 1 Please Draw Neighborhood Equivalence Class Tree Q29432264 . . . .

 

Given the following query q and data graph G. AU 1) Please draw a Neighborhood Equivalence Class tree (NEC tree) of query q. (5 marks) The Neighborhood Equivalence Class(NEC) of a query vertex u is a set of query vertices, which are equivalent to u. The equivalence is defined as follows: Let 2 be an equivalence relation over all query vertices in q such that, lli ( E rg))24( E V (g)) if for every embedding m that contains (ui, w and (ui, 0% VyE g)) there exists an embedding msuch that m-m-l(ui, V). (uj, v))U(ui)
