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

Knowledge Organization Systems (KOSs) use arrays of related concepts to capture the ontological content of a domain; hierarchical structures are typical of such systems. Some KOSs also employ sets of crossconceptual descriptors that express different dimensions within a domain-facets. The recent increase in the prominence of facets and faceted systems has had major impact on the intension of the KO domain and this is visible in the domain's literature. An interesting question is how the discourse surrounding facets in KO and in related domains such as information science might be described. The present paper reports one case study in an ongoing research project to investigate the discourse of facets in KO. In this particular case, the formal current research literature represented by inclusion in the "Library, Information Science & Technology Abstracts, Full Text" (LISTA) database is analyzed to discover aspects of the research front and its ongoing discourse concerning facets. A datasets of 1682 citations was analyzed. Results show thinking concerning information retrieval and the semantic web resides alongside implementation of faceted searching and the growth of faceted thesauri. Faceted classification remains important to the discourse, but the use of facet analysis is linked directly to applied aspects of information science.

Abstract

As we all know, Knowledge Organization (KO) is a pretty broad domain. Although the concept-theoretic approach to classification is at the core along with several other important pieces of what we call classification theory, both the intension and the extension of the domain are represented by broad trajectories. Arguably, the biennial conferences represent way stations within the matrix of the domain-points in time when we pause to take stock of our current research. Also, because each conference is hosted and planned by a regional chapter, each then reflects peculiar parameters of the intersections of intensional and extensional trajectories. Perhaps because the domain of knowledge itself is so immense, so also is our corporate attempt to grapple with the theoretical and applied aspects of its organization. Furthermore, because of the breadth of our domain, many possibilities exist for its representation, depending on the constitution of the research front (or fronts) at any moment in time. That is, research in the domain stretches in all directions from its solid theoretical core down many much more granular roadways. Thus by analyzing the activity and contents of these metaphorical way stations-that is, by bring the tools of domain analysis to bear on our own biennial conferences-we are able to visualize the moment in time represented by the accumulated scholarship generated by each conference. 2010's 11th International ISKO Conference in Rome offered the latest opportunity for analysis on a broad scale.

Abstract

Knowledge Organization (KO) as a domain is evolving rapidly and its boundaries are being pushed amoeba-like in every direction as a consequence. All that readers of this journal need to do to find evidence of this evolution is to look at the journal itself, which moves from quarterly to bi-monthly with this issue. While the peer-review system serves a gate-keeping function on the intension of the domain, making certain that articles appearing in this journal align with accepted conceptual tenets, the system simultaneously serves a different function (perhaps we can align it with the opening of gates) for KO conferences, where it is the extension of the domain that is constantly being probed and tested by new research. Gate-keeping is an important function for any domain, which is why peer review is a hallmark of ISKO's regional and international conferences as well as this journal. So it is even more impressive to consider these two functions together, which at once serve to intensify the core concepts of knowledge organization and simultaneously to stretch their application into new corners of the knowledge domain. It is a sort of inspiration-expiration dichotomous action, solidifying the core on the intake and pushing the boundaries (or axes, as Tennis (2003) has called them) on the outgo. Indeed, the new "Forum: Philosophy of Classification," and occasional feature beginning with this issue, which has been generated by Birger Hjørland, chair of ISKO's newly active Scientific Advisory Council, is an example of this dichotomous action. For further examples we can turn to the contents of regional and international KO conferences, which provide interesting temporal glimpses of this evolutionary process. In this editorial I will present a summary analysis of the August 2007 Mexico City conference "I Simposio Internacional sobre Organizacion del Conocimiento, Bibliotecologia y Terminologia," whose proceedings were just available in print in 2009.
