This example treats the input graph as a weighted, directed network (WDN).

Input

Input tables are from LocalClusteringCoefficient Example: WUN:

  • Edges: trade
  • Vertices: country

SQL Call

SELECT * FROM LocalClusteringCoefficient (
  ON trade AS Edges PARTITION BY fromid
  ON country AS Vertices PARTITION BY countryid
  USING
  TargetKey ('toid')
  EdgeWeight ('tradeweight') 
  Directed ('t') 
  Accumulate ('countryid')
) AS dt ORDER BY countryid;

Output

 countryid in_degree out_degree bi_degree cyc_tri_cnt mid_tri_cnt in_tri_cnt out_tri_cnt tri_cnt cyc_cc mid_cc in_cc out_cc  avg_cc  w_cyc_cc w_mid_cc w_in_cc w_out_cc w_avg_cc
