Abstract
We present theoretical rudiments of Petri nets over ontological graphs as well as their possible application to model medical procedures on the example of triage. Petri nets are a graphical and formal tool of modelling structures and dynamics of various types of systems. In Petri nets over ontological graphs, the domain knowledge is enclosed in a form of ontologies. In the presented approach, ontological graphs are obtained from ontologies built in accordance with the OWL 2 Web Ontology Language. Ontologies specify, among others, concepts and the relations between them in individual areas of life, for example in medicine as it is shown in the paper. Therefore, Petri nets over ontological graphs combine the power of graphical and formal description of the structure and behavior of systems with operations on linguistic data in the form of concepts and relations between them.
