Evaluation of Ontology Evolution Process

This page describes the evaluation done for the ontology evolution process along with screen shots of the ontology being evolved. The output of the system is captured for the following ontology changes:

  1. Ontology Expansion
  2. Support Update
  3. Concept Removal
  4. Ignore Evidence

Ontology expansion

Ontology Expansion for an incoming Evidence

Concept Removal

Ignore Evidence

An evidence is ignored iff, Constraints do not allow expansion of the ontology and support associated with the evidence is lower than all the concepts in the ontology. This happens when the ontology has expanded to it's maximum bound by its constraints.
