Graph mining Background Cloud computing Contributions Frameworks for large data processing in the cloud Conclusion Related works Background Graph A graph is denoted as G = ( V , E ) where V is a set of nodes and E is a set of edges. Subgraph A graph G ′ = ( V ′ , E ′ ) is a subgraph of another graph G = ( V , E ) iff: V ′ ⊆ V , and E ′ ⊆ E ∩ ( V ′ × V ′ ). Density The density of a graph G = ( V , E ) is 2 ·| E | calculated by density ( G ) = ( | V |· ( | V |− 1)) . Sabeur Aridhi Mining Large Datasets - Big Data Forum - Lyon 10 / 50
