PageRank

Gradoop Integration for KNIME Workbench version 1.0.0.v201911212144 by Steffen Dienst

Computation of the PageRank scores for the vertices in a logical graph. Uses the Flink Gelly implementation of PageRank and computes a per-vertex score which is the sum of PageRank scores transmitted over in-edges. Each vertex's score is divided evenly among out-edges. High-scoring vertices are linked to by other high-scoring vertices; this is similar to the 'authority' score in HITS (see http://ilpubs.stanford.edu:8090/422/1/1999-66.pdf). The current implementation excludes vertices with a degree of zero from the logical graph!

Options

Damping Factor
Set the factor for the damping.
Fixed Iterations
Select the number of fixed iterations.

Input Ports

Icon
One single logical graph.

Output Ports

Icon
Same graph with added page rank attribute on each vertex.
