Fig. 10
Two bi-patterns q=(q1,∅) and \(q^{\prime }=(q^{\prime }_{1}, \emptyset)\) with homogeneity less than 0.003. On the left the core subgraph represents the two cooperating stars Jianyong Wang and Lizhu Zhou who share labels q1= {data,databas,efficy,graph,keyword,mine,query,search,web,xml}. The core subgraph on the right represents the two stars Jianyong Wang and Mohammed Zaki sharing labels \(q^{\prime }_{1}=\){cluster,data,efficy,frequ,graph,mine,pattern,query} in a competitive configuration. See Table 4 the authors associated to these vertices
