Hello, In the documentation of the LocalClusteringCoefficient algorithm, it is said:
*The local clustering coefficient measures the connectedness of each vertex’s neighborhood.Scores range from 0.0 (no edges between neighbors) to 1.0 (neighborhood is a clique).* https://ci.apache.org/projects/flink/flink-docs-release-1.1/apis/batch/libs/ gelly.html#local-clustering-coefficient <https://ci.apache.org/projects/flink/flink-docs-master/dev/libs/gelly/library_methods.html#local-clustering-coefficient> However, upon running the algorithm (undirected version), I obtained values above 1. The result I got was this. As you can see, vertex 5113 has a score of 11: (the input edges for the graph are shown further below - around *35 edges*): (4907,(1,0)) *(5113,(11,0))* (6008,(0,0)) (6064,(1,0)) (6065,(1,0)) (6107,(0,0)) (6192,(0,0)) (6252,(1,0)) (6279,(1,0)) (6465,(1,0)) (6545,(0,0)) (6707,(1,0)) (6715,(1,0)) (6774,(0,0)) (7088,(0,0)) (7089,(1,0)) (7171,(0,0)) (7172,(1,0)) (7763,(0,0)) (7976,(1,0)) (8056,(1,0)) (9748,(1,0)) (10191,(1,0)) (10370,(1,0)) (10371,(1,0)) (14310,(1,0)) (16785,(1,0)) (19801,(1,0)) (26284,(1,0)) (26562,(0,0)) (31724,(1,0)) (32443,(1,0)) (32938,(0,0)) (33855,(1,0)) (37929,(0,0)) This was from a small isolated test with these edges: 5113 6008 5113 6774 5113 32938 5113 6545 5113 7088 5113 37929 5113 26562 5113 6107 5113 7171 5113 6192 5113 7763 9748 5113 10191 5113 6064 5113 6065 5113 6279 5113 4907 5113 6465 5113 6707 5113 7089 5113 7172 5113 14310 5113 6252 5113 33855 5113 7976 5113 26284 5113 8056 5113 10371 5113 16785 5113 19801 5113 6715 5113 31724 5113 32443 5113 10370 5113 I am not sure what I may be doing wrong, but is there perhaps some form of normalization lacking in my execution of: org.apache.flink.graph.library.clustering.undirected.LocalClusteringCoefficient.Result; org.apache.flink.graph.library.clustering.undirected.LocalClusteringCoefficient; Am I supposed to divide all scores by the greatest score obtained by the algorithm?
