                Abstract: 
                We present in this paper a small formal cybercrime ontology by using concrete tools. The purpose is to show how law articles and legal cases could be defined so that the problem of case resolution is reduced to a classification problem as long as cases are seen as subclasses of articles. Secondly, we show how counterfactual reasoning may be held over it. Lastly, we investigate the implementation of an hybrid system which is based both on this ontology and on a non-monotonic rule based system which is used to execute, in a rule based way, an external ontology dealing with a technical domain in order to clarify some of the technical concepts.
