Incipit.LogosLink.OntologyEngine 2.0.0.2

Introduction

Thank you for downloading this LogosLink package.

LogosLink is a set of tools for discourse analysis, as described in www.iatml.org. You can use LogosLink as an interactive desktop app or by adding the relevant packages to your project.

This is the Incipit.LogosLink.Ontology package, which contains types to manage ontology datasets in terms of their categories, atoms, properties, links, etc.

How to Get Started

Once you have added this package to your project, you can create ontology datasets, load and save them from disk, and run multiple analytics on them.

Use the Ontology and OntologyPersister classes to create, load and save ontology datasets. Use the different classes under the Incipit.LogosLink.OntologyEngine.Analytics namespace to run analytics on an ontology.

Additional Documentation

Please see the LogosLink Programmer's Guide for complete documentation.

Samples

You can create a new ontology like this:

var on = new Ontology("Test", "YourUserName");

Then, you can add, edit and delete ontology elements like this:

//add a category with some properties.
var cat1 = on.AddNewCategory("Animal");
cat1.Definition = "A living organism that feeds on organic matter.";
var py1 = cat1.AddNewProperty("Species");
var py2 = cat2.AddNewProperty("Age");

//add an atom representing 7-year-old Fido the dog.
var at1 = on.AddNewAtom(cat1, "Fido");
at1.AddNewValue(py1, "Dog");
at1.AddNewValue(py2, "7");

//delete everything.
at1.Delete();
cat1.Delete();

You can load and save ontology datasets like this:

//load an ontology from a file.
var onp = new OntologyPersister("YourUserName");
var on = onp.LoadOntology("C:\\Datasets\\My Ontology.llo").Ontology;

//save it back to disk.
onp.SaveOntology(on, null, "C:\\Datasets\\My Ontology.llo");

You can run some analytics on an ontology like this:

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

//dump entity centralities to the console.
foreach (var kvp in ana.EntityCentralities)
{
	Console.WriteLine($"Entity: {kvp.Key}\tCentrality: {kvp.Value.OverallCentrality}");
}
