Conceptual Modeling is a discipline of great relevance to several areas in Computer Science. In a series of papers [1,2,3] we have been using the General Ontological Language (GOL) and its underlying upper level ontology, proposed in [4,5], to evaluate the ontological correctness of conceptual models and to develop guidelines for how the constructs of a modeling language (UML) should be used in...

Conceptual modeling is the foundation of system analysis and design methodologies. It is challenging because it requires a clear understanding of an application domain and the ability to translate the requirement specification into a conceptual data model. Semi-automated conceptual data modeling is a process of using an intelligent tool to aid the modeler for the purpose of building a quality c...

a typical iranian carbonate matrix block surrounded by an open fracture was modeled in order to understand the fracture-matrix interaction and realize how to model the interaction best. the modeling was carried out by using a fine-scaled eclipse model in the single porosity mode (the fractures were explicitly modeled). the model was extended to a stack of 6 matrix blocks to understand block-to-...

The use of function has been recognized as an important part of the design process over last two decades, especially at the conceptual design stage, due to its critical role in determining the final product’s functionality. Although there are now some general methodologies dealing with functions or reasoning about functions, virtually no commercial CAD system can support conceptual design proce...

UML class diagrams can be used as a language for expressing a conceptual model of a domain. In a series of papers [1,2,3] we have been using the General Ontological Language (GOL) and its underlying upper level ontology, proposed in [4,5], to evaluate the ontological correctness of a conceptual UML class model and to develop guidelines for how the constructs of the UML should be used in concept...

The Defence Conceptual Modeling Framework (DCMF) is the Swedish Defence Research Agency’s (FOI) proposal for conceptual modeling in the military domain. DCMF enables the conceptualization, composition, visualization, and reuse of knowledge for modeling and simulation. To achieve these aims, DCMF requires that its final products— conceptual models expressed as Base Object Models (BOMs)—-are embe...

This paper describes a category theory semantics for conceptual data modeling. The conceptual data modeling technique used can be seen as a generalization of most existing conceptual data modeling techniques. It contains features such as specialization, generalization , and power types. The semantics uses only simple category theory constructs such as (co)limits and epi-and monomorphisms. There...

Objectives: Hypertension is a global major health challenge and mechanisms related to the risk factors associated with it are poorly understood. Therefore, we used structural modeling to test a hypothesized model to identify factors associated with hypertension.  Methods: A cross-sectional population based survey, was performed and the data related to a random representative sample of 9704 sub...

In this paper we argue that conceptual modeling is well suited to define a convincing profile for the information systems discipline. Different from empirical research, conceptual modeling should not only represent existing domains. To fully exploit the potential offered by information technology, conceptual models should also represent constructions of future reality. While such an approach is...

This paper describes the conceptual integration and computer-based support of two important groups of conceptual data models, Entity Relationship Models and Object Role Models (e.g. NIAM). We perform conceptual integration using the conceptual data modelling language CoCoA to specify separate data models of individual notations. We then merge these into an integrated conceptual data model for b...
