Evaluation Metrics for Ontology Modules

A modular approach to ontology development, enables reuse and enhance maintainability. Ontology modules can either be extracted from a large ontology or built from scratch and then aligned to construct a large ontology. The evaluation of these modules is very important. However, upto now only one tool has been developed for this purpose and it does not consider the evaluation of the ontology modules developed from scratch. In this paper the list of evaluation metrics identified for the evaluation of both types of ontology modules is presented. The metrics have been grouped into six categories and also needful has been done to identify metrics which can be used to evaluate ontology modules developed from scratch.
