Abstract

This paper maps the concepts "space" and "dimensionality" in classifications, in particular in visualizations hereof, from a historical perspective. After a historical excursion in the domain of classification theory of what in mathematics is known as dimensionality reduction in representations of a single universe of knowledge, its potentiality will be explored for information retrieval and navigation in the multiverse of the World Wide Web.

Abstract

Purpose - This paper seeks to outline the central role of concepts in the knowledge universe, and the intertwining roles of works, instantiations, and documents. In particular the authors are interested in ontological and epistemological aspects of concepts and in the question to which extent there is a need for natural languages to link concepts to create meaningful patterns. Design/methodology/approach - The authors describe the quest for the smallest elements of knowledge from a historical perspective. They focus on the metaphor of the universe of knowledge and its impact on classification and retrieval of concepts. They outline the major components of an elementary theory of knowledge interaction. Findings - The paper outlines the major components of an elementary theory of knowledge interaction that is based on the structure of knowledge rather than on the content of documents, in which semantics becomes not a matter of synonymous concepts, but rather of coordinating knowledge structures. The evidence is derived from existing empirical research. Originality/value - The paper shifts the bases for knowledge organization from a search for a universal order to an understanding of a universal structure within which many context-dependent orders are possible.

Abstract

Contrasts in 20th century classification theory relate to a transition from a universe of "knowledge" system towards one of "concepts' Initiatives to develop a Simple Knowledge Organization Systems (SKOS) standard based on classification schemes and taxonomies within the framework of the Semantic Web (SW) are attempts to bridge the gap. Current knowledge organization systems (KOS) seem to reinforce "syntactics" at the expense of semantics. We claim that all structure is syntactic but knowledge structures need to have a semantic component as well. Therefore we consider classifications as artificial languages. The Universal Decimal Classification (UDC) constitutes a natural language-independent notation system that allows for mediating between concepts and knowledge systems. We discuss an elementary theory of knowledge organization based on the structure of knowledge rather than on the content of documents. Semantics becomes not a matter of synonymous concepts, but rather of coordinating knowledge structures. The interactions between these systems represent interactions between different universes of knowledge or concepts.

Abstract

Discoveries in high energy physics have led to new understanding about the nature of that which exists. We use the metaphor of the particle collider to accumulate components of a theory of knowledge that underlies the science of knowledge organization. We outline the concepts of a knowledge universe, the central role of concepts, and the intertwining roles of works, instantiations and documents. This thought experiment provides a different epistemological reading of "knowledge" by demonstrating a semantics that is based on structure and on related forces between components, rather than on content, so as to enable the development of mechanisms for linking related knowledge entities with so-far undiscovered similarities.

Abstract

In the 1950s, the "universe of knowledge" metaphor returned in discussions around the "first theory of faceted classification'; the Colon Classification (CC) of S.R. Ranganathan, to stress the differences within an "universe of concepts" system. Here we claim that the Universal Decimal Classification (UDC) has been either ignored or incorrectly represented in studies that focused on the pivotal role of Ranganathan in a transition from "top-down universe of concepts systems" to "bottom-up universe of concepts systems." Early 20th century designs from Paul Otlet reveal a two directional interaction between "elements" and "ensembles"that can be compared to the relations between the universe of knowledge and universe of concepts systems. Moreover, an unpublished manuscript with the title "Theorie schematique de la Classification" of 1908 includes sketches that demonstrate an exploration by Paul Otlet of the multidimensional characteristics of the UDC. The interactions between these one- and multidimensional representations of the UDC support Donker Duyvis' critical comments to Ranganathan who had dismissed it as a rigid hierarchical system in comparison to his own Colon Classification. A visualization of the experiments of the Knowledge Space Lab in which main categories of Wikipedia were mapped on the UDC provides empirical evidence of its faceted structure's flexibility.
