Over the last few years, clinical efforts have focused on improving the interconnection and interoperability in accordance with the changes of the health treatments, which have moved from isolated to distributed. This change has generated amount of knowledge and also heterogeneity of information. This fact has caused the use of standards like SNOMED-CT and ICD-10. For this reason, in this project, we propose a model called DIONE ontology to represent the ICD-10-CM disease concepts using the OWL (Web Ontology Language). The methodology adopted can be classified into several steps: 1) the creation of a hierarchy with the ICD-10-CM disease concepts, 2) the ICD inclusion terms for each concept by means of the SNOMED/ICD-10-CM alignments provided by UMLS and BioPortal and 3) the consistency checking of the DIONE ontology and the T-Box classification using a OWL-DL reasoner like ELK. In further work, this project will involve the development of an end-user application that could be used to guide specialists in the biomedicine field to make a diagnosis from patient records.

In order to visualize the DIONE ontology using a software like Protégé, the download section offers a registration form where a username and password are required.
