Construction and evaluation of metaontology using databases

Ontologies perform the cumbersome task of translating data on the web into a form suitable for manipulation by machines. The discovery of concepts and relationships from unstructured text is a crucial and challenging task in constructing ontology (s). A pragmatic solution is offered by a metaontology as it supplements the ontology with related concept pairs and relationships. An ideal approach to construct a metaontology is to employ databases as they save on the time required to store, retrieve and update data. The relationships in the database are augmented by converting them into a graph to determine transitive relationships. Accuracy is ensured by integrating only those relationships with the ontology which have a high degree of certainty. This is affirmed by the evaluation and the results obtained using the ontology constructed along the lines of the metaontology.
