Representing things and properties in conceptual modelling: an empirical evaluation
نویسندگان
چکیده
The representation of things and properties is a fundamental issue in conceptual modelling. Important theoretical issues surrounding the representation of things and properties remain unresolved. For example, proponents of object-role modelling argue that there should be no distinction between things and properties, while proponents of entity-relationship modelling argue that the distinction is important but provide ambiguous guidelines about how the distinction should be made. In this paper, we use ontological theory to support our arguments about how things and properties should be represented. We describe an experiment that we undertook to test whether an ontologically sound representation of things and properties enabled users to better understand a domain than two other alternative, widely used representations. Our results provide evidence to support the use of ontologically sound representations of things and properties in conceptual modelling.

Representing Classes of Things and Properties in General in Conceptual Modelling: An Empirical Evaluation
How classes of things and properties in general should be represented in conceptual models is a fundamental issue. For example, proponents of object-role modelling argue that no distinction should be made between the two constructs, whereas proponents of entity-relationship modelling argue the distinction is important but provide ambiguous guidelines about how the distinction should be made. In...
متن کاملA Probabilistic Model of Learning Fields in Islamic Economics and Finance
In this paper an epistemological model of learning fields of probabilistic events is formalized. It is used to explain resource allocation governed by pervasive complementarities as the sign of unity of knowledge. Such an episteme is induced epistemologically into interacting, integrating and evolutionary variables representing the problem at hand. The end result is the formalization of a p...
متن کاملNumerical modelling of the underground roadways in coal mines– uncertainties caused by use of empirical-based downgrading methods and in situ stresses
Numerical modelling techniques are not new for mining industry and civil engineering projects anymore. These techniques have been widely used for rock engineering problems such as stability analysis and support design of roadways and tunnels, caving and subsidence prediction, and stability analysis of rock slopes. Despite the significant advancement in the computational mechanics and availabili...
متن کاملThe conceptual structure of cabbages and things
In 1994Eleanor Saffran co-authoredwithMyrna Schwartz a seminal review of semantic memory impairments and their implications for the representational format and organisation of conceptual knowledge. In that paper, they argued that conceptual knowledge is distributedacross a network of different sub-systems or ‘‘attribute domains,’’ including at least a perceptual and functional or propositional ...
متن کاملAn Experimental Evaluation of Property Precedence in Conceptual Modelling
Interest in evaluating conceptual modelling techniques has recently experienced a revival, in part due to widespread adoption of the Unified Modelling Language (UML). In addition, the use of ontology as a framework for evaluating conceptual modelling techniques has gained acceptance. In this paper, we consider implications of applying one aspect of the ontology of Mario Bunge to conceptual mode...
