Item Property (KnowledgeGraphCentralityScores)

In This Topic

Indexer to retrieve the array of scores for a specific entity identified by its UID.

Syntax

C#
Visual Basic (Declaration)

public double[] this[ 
   object uid
]; {get;}

Public ReadOnly Default Property Item( _
   ByVal uid As Object _
) As Double()

Parameters

uid

Property Value

The array of centrality measure scores for the given entity

Remarks

Returns the scores for the centrality computation for the input uid used as the key to the indexer. The returned array of scores contains one score, or "result", per input ArcGIS.Core.CIM.CentralityMeasure used in the centrality analysis. Scores are arranged in the array in the same order as the measures in the input measures array.
. Note: The uid is the entity object identifier (refer to ArcGIS.Core.Data.Knowledge.KnowledgeGraphNamedObjectValue.GetID)

Example

Output Centrality Results

//using ArcGIS.Core.Data.Knowledge.Extensions;

await QueuedTask.Run(() =>
{
  ///var config = ...;
  //var subGraph = ...;
  //var measures = ...;

  var results = kg.ComputeCentrality(config, subGraph, measures);
  //loop through each (entity) named type (relates are never included in results)
  foreach (var named_type in results.NamedTypes)
  {
    //Get the entity uids for each named type
    foreach (var uid in results.GetUidsForNamedType(named_type))
    {
      //Get the scores for each uid via the [] indexer on "Scores"
      var scores = results.Scores[uid];
      //There is one score per measure in the input measures array
      //Note: results.Scores.Measures is also provided for convenience...
      //for (int m = 0; m < results.Scores.Measures.Length; m++)
      for (int m = 0; m < measures.Length; m++)
      {
        var score = scores[m];//score for the given measure
                                //TODO - use measure score

      }
    }
  }
});
