    Abstract
    Mathematical modelling is a field of applied mathematics with applications in other disciplines. The availability of a formal ontology and derived benefits, such as the possibility of conducting automated reasoning about the ontological classes of the domains, greatly reduce the barrier of entry in the field for non-experts, while helping the establishment of a more precise and controlled vocabulary among the domain experts involved in mathematical modelling. This work focuses on Mathematical Models applied to the natural sciences and as a case study the field of mathematical epidemiology has been chosen for this ontology. We propose the development of an ontology of mathematical models which is general enough and not restricted in its applicability, yet is developed considering the specific needs of a particular application domain.
