This paper presents the C-VISTA model enabling viewpoint representation for improving knowledge modelling from several experts: this model can thus be used for cooperative building of an ontology. We describe the C-VISTA model in the framework of conceptual graph formalism.
Background and Aim: The current research aims to develop a literature-dependent and expert-modified model related to credibility evaluation of web information. Methods: Regarding the approach, mixed method would be utilized. The research method then is mixed-heuristic using both qualitative and quantitative methodologies. In the first stage of the research, meta- synthesis was used as a qualita...
Introduction: The importance and necessity of designing a conceptual model of curriculum is one of the important issues in the educational system of a country. Given the current status of the education system, which does not use a comprehensive model concept at all levels to design and formulate a curriculum, therefore, this descriptive study provides a comprehensive conceptual framework. Metho...
In this paper we focus on the transformation of a conceptual schema into an internal schema. For a given conceptual schema, quite a number of internal schemata can be derived. This number can be reduced by imposing restrictions on internal schemata. We present a transformation algorithm that can generate internal schemata of several types (including the relational model and the NF 2 model). Gui...
The Forward Search is a powerful general method for detecting anomalies in structured data, whose diagnostic power has been shown in many statistical contexts. However, despite the wealth of empirical evidence in favour of the method, only few theoretical properties have been established regarding the resulting estimators. We show that the Forward Search estimators are strongly consistent at th...
