We found that some important errors are missing like sufficient omission error and disjoint redundancy relation error in error¿s taxonomy. We have defined and categorized them in incompleteness and redundancy categories of error¿s taxonomy respectively. Due to importance of such errors, we proposed the system DSR_WG, which has capability to detect all these types of errors. The system use a coding scheme and overlapping rules to accomplish the job. Before using the rules in the system we have also tested them with different angles. Our ontology evaluation system has decreased the burden from human experts and covered such areas, which are not handled by any available evaluation tool.
