Sufficient Knowledge Omission Error and Redundant Disjoint Relation in Ontology

Ontology evaluation is as important as its designing and application. Researchers have identified different errors which should be catered in ontology evaluation process and classified them in error’s taxonomy. We have found that some important errors are missing in the error’s taxonomy. We have identified and defined new errors i.e. sufficient knowledge omis-sion error (SKO) and redundancy disjoint relation error (RDR) and catego-rized them in appropriate category of error’s taxonomy.
