Abstract

CAMPOS, Maria Luiza de Almeida. Modelling of knowledge domains: an investigation of fundamental princips. Ci. Inf. [online]. 2004, vol.33, n.1, pp. 22-32. ISSN 0100-1965.  http://dx.doi.org/10.1590/S0100-19652004000100003.

Theories and methodologies developed within the subject scope of both Information Science and Computer Science and designed to knowledge representation, present, in a somewhat comprehensive way, discussions on principles such as knowledge contexts, nature of concepts, relationships between concepts and systems of concepts. Thus, in terms of theoretical framework, abstraction models used by the two fields are investigated. As to Computer Science, representational models related to the modeling of data bank systems are investigated, more specifically the object-oriented model. Concerning information science, theories related to the representation of systems of concepts are analyzed, such as the theory of faceted classification and the theory of concept. As to the theory of terminology, principles established for determining concepts and their relationships are used. While assuring the specificity of each area, theories are compared, aiming at four topics related to the modeling process: the method of reasoning; the object of representation, the relationships among objects; the forms of graphical representation.

Keywords : Knowledge organization; Modeling; Knowledge representation.
