This paper describes an approach to database inference analysis based on conceptual graphs. The database inference problem is briefly described. Previous approaches are summarized, followed by a presentation of our inference model, called AERIE. The notions of an inference target class and an inference method class are introduced with examples given. Conceptual graphs are introduced as our mean...

OLAP (On-Line Analytical Processing) tools support the decision-making process by giving users the possibility to dynamically analyze high volumes of historical data using operations such as roll-up and drill-down. These operations need well-defined hierarchies in order to prepare automatic calculations. However, many kinds of complex hierarchies arising in real-world situations are not address...

In this paper, Aitana, a Developmental Cognitive Artifact developed byMarques (2006), is used to produce “conceptual” representations of the best known Cellular Automata (CA) rules that perform the Density Classification Task (DCT) (see e.g. Packard, 1984, 1988; Mitchell et al., 1993). The resulting redescriptions are then analysed from the viewpoint of their similarity, in terms of their cell ...

BACKGROUND Patient-clinician communication is thought to be central to care outcomes, but when and how communication affects patient outcomes is not well understood. OBJECTIVE We propose a conceptual model and classification framework upon which the empirical evidence base for the impact of patient-clinician communication can be summarized and further built. DESIGN We use the proposed model...

In this paper I analyze the cognitive function of symbols, figures and diagrams. The analysis shows that although all three representational forms serve to externalize mental content, they do so in radically different ways, and consequently they have qualitatively different functions in mathematical cognition. Symbols represent by convention and allow mental computations to be replaced by epist...

The Revised European-American Classification of Lymphoid Neoplasms (REAL) classification has been validated by a multi-institutional study, and project data showed that it is both reproducible and clinically relevant. The new World Health Organization (WHO) Classification of Neoplastic Diseases of Hematopoietic and Lymphoid Tissues, as a joint project of the Society of Hematopathology and Europ...

The notion of conceptual structure in CA rules that perform the density classification task (DCT) was introduced by [1]. Here we investigate the role of process-symmetry in CAs that solve the DCT, in particular the idea of conceptual similarity, which defines a novel search space for CA rules. We report on two new process-symmetric onedimensional rules for the DCT which have the highest “balanc...

This paper presents a classification scheme that articulates the categorisation of subject matter. Two basic classificatory devices are introduced: (a) a feature representing the resulting category characterised by a property that the feature denotes, (b) a dimension representing a perspective that partitions the Universe of Discourse (UoD) or a category. A classification based on a dimension c...

This paper focuses on the issues of categorical database generalization and emphasizes the roles of supporting data model, integrated data model, spatial analysis and semantic analysis in database generalization. The framework contents of categorical database generalization transformation are defined. The paper presents an integrated spatial supporting data structure, a semantic supporting mode...

The paper discusses the use of discrete-event simulation in design and operation of body and paint shops in North American Vehicle Assembly Plants. Two broad classifications are given on the use of simulation in body and paint shops. First classification is based on the stage of development of the system. Four categories are observed in this classification. Namely: conceptual design phase, deta...
