Conceptual Modelling http://www.inf.ufes.br/~gguizzardi/Conceptual_Modeling_EJC(1).pdf
This presentation contributes to the philosophical foundations of conceptual modeling by addressing a number of foundational questions such as: What is a conceptual model? Among models used in computer science, which are conceptual, and which are not? How are conceptual models different from other models? The presenation takes a stance in answering these questions and, in order to do that, it draws from a broad literature in philosophy, cognitive science, Logics, as well as several areas of Computer Science. After a brief history of conceptual modeling, the presentation addresses the aforementioned questions by proposing a characterization of conceptual models with respect to conceptual semantics and ontological commitments.
