Abstract

At the last Digital Library Conference in London two workshops took place - both (in parallel) devoted to the use of visualization in presenting and navigating large collections. One was entitled Search Is Over! and of the other Knowledge Maps and Information Retrieval. This anecdotal evidence stands for the growing and accelerating quest for visually enhanced interfaces to collections. Researchers from information visualization, computer human interaction, information retrieval, bibliometrics, digital humanities, art and network theory in parallel, often also in ignorance of each other, sometimes in interdisciplinary alliances are engaged in this quest. This paper reviews the current state-of-the-art, with special emphasis on the work of the COST Action TD1210 Knowescape. We discuss in more depth two examples of the use of visual analytics to create a fingerprint of an archive or a library, a data archive and a national library. We present examples from the micro-level of monitoring activities of users, over the meso-level to visualize features of bibliographic records, to macroscopes (a term coined by Katy Borner) into libraries and archives. We also discuss how different ways to perform visual analytics inform each other, how they are related to questions of data mining and statistical analysis, and which methods need to be combined or which communities need to collaborate. To illustrate some of these points we analysed Universal Decimal Classification (UDC) codes in bibliographic datasets of the National Library of Portugal. This is a potential still awaiting to be fully exploited in improving interfaces to subject access and management of classification data. It should be noted that UDC notation strings stored in bibliographic databases require specialist knowledge in both UDC and programming for any visualization tools to be applied. This UDC Seminar which is devoted to authority control is an opportunity to draw attention to the possibilities in visualization whose wider application depends on the readily structured, richer and more transparent subject metadata.

Abstract

Bibliocentricity in the library catalog arose from the practice of resource description, which emerged from the simple listing of books as objects with little reference to their intellectual content. Combined with shifting cultural conceptions of authorship, this led to a complex system in which the implicit concept of "goodness" affected the efficacy of description of varying resources. Issues of domain-specificity, cultural origins or contexts of usage have been disregarded in deference to book-like considerations. RDA (Resource Description and Access provides for analytical descriptions using the knowledge-based FRBR conceptual model of entities based on the artifactual intersection of intellectual works and cultural information carriers. The more empirically- based FRBRoo, an object-oriented revision of the conceptual model, reflects the atemporality of instantiation. FRBRoo seems promising as a potential additional facet for expressing structural components of knowledge represented by traditionally conceptual KOSs. In this study two cases are analyzed from the point of view of both RDA and FRBRoo. Analysis shows how little synergy has been gained through RDA's implementation of the FRBR model. The cases analyzed using RDA and FRBRoo serve as artifacts of cultural discourse, by which the measure of objective violence reflects the degree to which individual works still cannot be disambiguated.

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

Classification systems are often described as stable reference systems. Sometimes they are accused of being inflexible concerning the coverage of new ideas and scientific fields. Classification as an activity is the basis of all theory-generating research, and also plays a powerful role in social ordering. It is obvious that the ways in which we seek information and in which information is provided has changed dramatically since the emergence of digital information processing and even more with the internet, and web-based technologies. The purpose of this paper is to illustrate the notion of a stable knowledge organization classification as a temporary stationary manifestation of an open and evolving system of classification. We compare the structure of the main classes in the Universal Decimal Classification (UDC) according to their usage of special auxiliaries to demonstrate the dynamic evolution of the UDC over time, as a stable reference system representing published organized knowledge. We view the ecology of the UDC, and discover that most changes are to the ecology itself as numbers are re-interpreted. This subtle type of change is a key to monitoring the evolution of knowledge as it is represented in the UDC's stable reference system.

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

A work is a deliberately created informing entity intended for communication. A work consists of abstract intellectual content that is distinct from any object that is its carrier. In library and information science, the importance of the work lies squarely with the problem of information retrieval. Works are mentefacts-intellectual (or mental) constructs that serve as artifacts of the cultures in which they arise. The meaning of a work is abstract at every level, from its creator's conception of it, to its reception and inherence by its consumers. Works are a kind of informing object and are subject to the phenomenon of instantiation, or realization over time. Research has indicated a base typology of instantiation. The problem for information retrieval is to simultaneously collocate and disambiguate large sets of instantiations. Cataloging and bibliographc tradition stipulate an alphabetico-classed arrangement of works based on an authorship principle. FRBR provided an entity-relationship schema for enhanced control of works in future catalogs, which has been incorporated into RDA. FRBRoo provides an empirically more precise model of work entities as informing objects and a schema for their representation in knowledge organization systems.
