Fig. 1From: VeilGraph: incremental graph stream processingThe contribution of vertex v diminishes as we expand further away from it (Eq. 7). Parameter \(\Delta\) dictates how far to expand around vertices until the accumulated fraction drops below \(\Delta\). \(v_{s}\) is the score of vertex v; \(d_{t}(v)\) is the out-degree of vertex v at measurement instant tBack to article page
