Ontological Analysis: Example

An exercise of ontological analysis suggested by Jean Rohmer:

“Pierre a un niveau en anglais professionnel insuffisant selon Paul pour diriger le projet Alpha, du moins tant que Jacques n’aura pas été nommé comme son adjoint, ce qui, selon les règles du Siège, devrait intervenir un peu avant l’officialisation de sa démission de son actuel poste de secrétaire général”

“Peter’s English professional fluency is, according to Paul, insufficient to manage project Alpha, at least until Jacques is named to assist him which, according to the standard rules, should happen some time before the publishing of the resignation of his current position as general secretary”

Using the Cake OWL2 kernel, the objective is to carry out a step-by-step analysis bringing together the different perspectives, from data analysis, to business intelligence.
