The discussion on transforming from OIL ontology to basic-element and complex-element of Extenics

OIL is an ontology representation language. Basic-element and complex-element are the basis of the formalization in Extenics and used to solve the contradiction problems. In the article, we firstly introduced OIL and the basic-element and complex-element. Secondly, we analyzed the primitive of OIL and the basic-element and complex-element, and gave the corresponding relation of them. Finally, we gave the mapping rules from OIL to the basic-element and complex-element. We researched how to transform the OIL ontology to the basic-element and complex-element, and supplied a way to build the knowledge domain to solve the contradiction problems.
