Nowadays, ontologies have become a key mechanism to represent the knowledge of a specific domain. Domain ontologies can be used for different purposes, one of them is the development of semantic search engines that obtain precise results by considering the meaning of the Web content. The construction of these ontologies usually requires a large amount of effort and time to be completed. One way of reducing such effort and time is using the reuse approach. When ontologies overlap, alignment techniques to merge such ontologies can be applied. However, the result of the ontology merging activity can be a very large ontology, difficult to understand and use. To overcome this problem, this paper describes a methodology, called CreaDO, to semi-automatically create domain ontologies. CreaDO focuses on performing a parameter-based ontology merge that allows the creation of a domain ontology only with relevant information for the ontology purpose.
