For Conceptual Modeling an appropriate modeling grammar needs to be selected. Approaches have been identified to evaluate and select a modeling grammar. It is supposed that theorybased approaches contribute to a more effective selection of modeling grammars than non-theory-based approaches. However, only two approaches that are theorybased identified lead to a single modeling grammar: Cognitive Fit and Ontology. Using both approaches as complements results more effective to solve a specific (conceptual) modeling task than the individual approaches do. Therefore, we combine both approaches to a procedure that facilitates a theory-based approach to select a modeling grammar.enText/Conference Paper1617-5468
