Carry Out Centrality Analytics on an Ontology

The following example shows how to run centrality analytics on an ontology.

To execute this code, you will need a reference to the OntologyEngine package.

    using Incipit.LogosLink.OntologyEngine;
    using Incipit.LogosLink.OntologyEngine.Analytics.Centrality;

    //load an ontology from a file.
    var onp = new OntologyPersister("MyUserName");
    var on = onp.LoadOntology("C:\\Temp\\Test Models\\Test Ontology.llo").Ontology;

    //prepare and run a centrality analyser.
    var ana = new CentralityAnalyser(on);
    ana.Run();

    //print out overall centralities.
    foreach (var kvp in ana.EntityCentralities)
    {
        Console.WriteLine($"{kvp.Key.ElementKind}: {kvp.Key.SimpleText}; Overall centrality: {kvp.Value.OverallCentrality:P2}");
    }

In lines 5-6, we load an ontology from a file.

In lines 9-10, we create a centrality analyser for the ontology just loaded, and run it.

In lines 13-16, we iterate the entity centrality results from the analyser. For each element, we print out the kind and simple text for the entity, followed by its overall centrality.
