The Ontology Engineering ProcessTraditionally In Linked Datacompetency through existing Ellicitatequestions, key Ellicitate domain informationknowledgeconcepts, etc. systems, etcModel diagrams, etc. Reuse fromfind commonlyknowledgeothersused vocabulariesRepresentalign, fill the gaps,OWL, RDFS, etc. Combineknowledgeetc.In both cases, it is expected that the data will somehow fitthe ontology, that the ontology will support relevantapplications, and support the inference of new information 8.

Conclusion Many existing works have considered theconnection between data mining and ontologyengineeing A large scale, web of linked data and ontologiesmake the related challenges more prominent and need real interactions between the twoapproaches, not as disconnected components. Need to investigate and exploit the colateralbenefits of ontology engineering and knowledgediscovery coming up with new techniques for enrichingknowledge from mined data, and guiding theextraction of further data wit ontological knowledge 15.
