Using Ontologies for Extracting Differences in the Dynamic Domain: Application on Cancer Disease

Over time, the data representatives a given domain can change, both the data model reflecting the area. In this situation, the presence of strategies that can summarize the produced changes is mandatory. This study presents an implemented approach based on data mining techniques in order to extract the differences, the model is domain ontology and the changes are represented by two ontology's versions. The results are summarized in changes report. An experimentation of the tool was made on the ontology of the cancer disease and satisfactory results were obtained
