Abstract

We understand "theory" to be a system of testable explanatory statements derived from research. In knowledge organization, the generation of theory has moved from an epistemic stance of pragmatism (based on observation of the construction of retrieval tools), to empiricism (based on the results of empirical research). In the nineteenth century, Panizzi (1841), Cutter (1876), and Dewey (1876), developed very pragmatic tools (i.e., catalogs and classifications), explaining as they did so the principles by which their tools were constructed. By 1950, key papers at a University of Chicago Graduate Library School conference on "Bibliographic Organization" recorded the role of bibliographic organization in civilization (Clapp, 1950) and deemed classification the basis of bibliographic organization (Shera, 1950). In 1961, the International Conference on Cataloguing Principles in Paris brought together key thinkers on the design of catalogs. Wilson (1968) expounded a system for bibliographic apparatus, and provided the framework for empirical theoretical development. In 2000, Svenonius asserted that knowledge organization is accomplished through a bibliographic language (or, more properly through a complex set of bibliographic languages), with semantics, syntax, pragmatics, and rules to govern their implementation. Logical positivism notwithstanding, rationalist and historicist stances have begun to come to the fore of late through the promulgation of qualitative methods, most notably those employed in classification, user-interface design, and bibliometric research.

Abstract

The purpose of this volume is to extend our understanding of the work entity and its role in information retrieval. Basic definitions are reviewed to provide a summary of current thought about works, their role in the catalog, and the potential for better accommodating them in future information retrieval environments. A discussion of entities for information retrieval and works as entities follows. Research in knowledge organization is summarized, indicating ways in which ontology, epistemology, and semiotics have lately been used as looking glasses through which to view the social informational roles of works.

Abstract

Works are key entities in the universe of recorded knowledge. Works are those deliberate creations (known variously as opera, oeuvres, Werke, etc.) that constitute individual sets of created conceptions that stand as the formal records of knowledge. In the information retrieval domain, the work as opposed to the document, has only recently received focused attention. In this paper, the definition of the work as an entity for information retrieval is examined. A taxonomic definition (that is, a definition built around a taxonomy) is presented. An epistemological perspective aids in understanding the components of the taxonomic definition. Works, thus defined as entities for information retrieval, are seen to constitute sets of varying instantiations of abstract creations. These variant instantiations must be explicitly identified in future systems for documentary information retrieval. An expanded perception of works, such as that presented in this paper, helps us understand the variety of ways in which mechanisms for their control and retrieval might better be shaped in future.

2. Collocation versus disambiguation Of course, the practical reality is that systems must accommodate dual purposes when they declare entities to be the same or different. We wish at once to collocate or draw together everything that is alike, and at the same time to disambiguate the collocated set. So, the tension between the two purposes holds every system in balance. A set of collocated entities is thought to contain entities that are the same to some degree, but different enough to require an approach to sorting the elements of the set. It reminds me again of Wilson, who said of relevance that sometimes people just want something that serves as a means to some end. What does that suggest about sameness and difference? Perhaps that "more or less the same" or "a little bit different" reveals a sort of fuzzy-set, which opens the brackets around the set of equivalent entities that have been collocated. If so, then it means all the more that the differences, no matter how slight, need to be accounted for in the disambiguation. Of course there is quite a lot of overlap among domains, especially among closely related domains. We can see that in the articles in the present issue of this journal. We have papers that have come from at least three domains, and yet they all treat of knowledge and its conceptual ordering. Yet there is little conformity among the works cited by these four papers. What does that tell us? Perhaps that different domains are a little bit the same?
3. A New Perspective: Theme and Variations In musicology there is a factual reality that every sound you hear can be reduced to a sort of calculus that expresses its tonal and metrical relationships. Schenkerian analysis (Forte and Gilbert 1982) is one approach to this. In the end it reveals a singular truth, which is that music (like information) is essentially an ordered accretion of energy. The beauty of this type of analysis is what it reveals when large quantities of music are analyzed-it reveals sets of similarities that might never have been noticed otherwise. The music information retrieval domain has built its technology and its science along these lines. So where does this leave knowledge organization? In the semantic Web and the magical kingdoms that will follow it, it will be necessary to make samenessdifference decisions of a different sort, to provide the ability to make heretofore unimaginable connections. Elsewhere I have asked when a funeral urn is like a ship's log: the answer is when the instantiation set has the same calculus in its scope, which tells us that the two artifacts have approximately equal impact factors along some cultural or social trajectory. These are the sorts of questions knowledge organization can be able to answer if we can move toward a large base of empirical evidence to which similarity measures can be applied and from which new hypotheses can be drawn to direct investigation. Why have these questions not yet been answered? Because they have not yet been posed."

Abstract

A major problem for bibliographic retrieval is an absence of explicit linkages to guide users among manifestations of a work. The purpose of this research was to enhance the power of bibliographic retrieval systems by providing contextual information about the derivative bibliographic relationship. Descriptive survey method was employed. A sample of 411 works from the Georgetown University on-line catalog was drawn. 49.9% of works were derivative. Age of a progenitor work is the characteristic most strongly associated with derivation; language and country of origin are indifferent predictors. Popularity of works might contribute to the phenomenon of derivation. The mean size of bibliographic families of derivative works was 8.44 members. The majority of bibliographic families had successive derivations, large groups of bibliographic families had translations and simultaneous editions; few had extractions, amplifications, or performances; none had adaptations. Successive derivations are the most commonly found members of bibliographic families, and are associated with most other types of derivation within bibliographic families. The bibliographic data required for explicit control of works might easily be compiled from existing records. The development of bibliographic retrieval systems in the network environment could play a dramatic role in improving retrieval of works

"Actions have consequences, and this is certainly true of knowledge organization. One reason our colleague Birger Hjoerland (1998) urges epistemological analysis for the problems of information science is that resources might well serve many different purposes for different users, and thus different user groups might have different epistemological relationships with resources. There is a difference between consulting a dictionary for a definition, reading a text for comprehension to increase your knowledge base, reading for pleasure (which, evidently boosts certain endorphins), and synthesizing a scientific report to generate an hypothesis, just to generate a few scenarios. The only commonality in that list is the consultation of a resource. In each case the purpose dictates the activity and is reliant upon a different epistemological aim. No online source of facts is going to suffice if I want something to read that will give me pleasure; no catalog of fine literature is sufficient for the extraction of scientific theory. Hjoerland also suggests that the names we give - to documents, to categories, even to activities - embodies the action of naming, and thereby also the action of facilitating or obfuscating the use of named resources (Hjoerland 2003, 98). Terminology cannot be neutral because the very selection of terms as names either provides a pathway to understanding or a barrier to usage, depending on the epistemological perspective of the user group. I won't go looking for Miss Marple in your dictionary if you call it a dictionary, even though it might contain a perfectly fine list of motives for murder. Likewise, as an information scientist I am not likely to look for research anywhere except in a database that purports to contain peer-reviewed scientific literature. Names have power, and the action of naming is powerful too. We in knowledge organization need to be aware that no matter how elegant our science, the actions based on our research have consequences. A model generated empirically might make an excellent explanation of a specific reality, but if it migrates into the structure of a system for knowledge organization it has the power to help or hinder assignment to categories, not to mention retrieval from those categories.
An important aspect of what we do is facilitating the curatorial aspect of information retrieval or librarianship. What I mean is that our job is not merely to "mark and park," as generations of catalogers famously have said of both resource description and classification, or even to generate parking spaces (to press my metaphor), but rather our job is to place each entity in the best category, each artifact in the best environment, each resource on the best "shelf" to enhance its usability should it actually be sought for retrieval. Hope Olson (2002) has also written about the limits we create when we exercise the power to name. We must be aware of the consequences of our science. In librarianship in the United States at the moment there is a fair amount of hand-wringing about the future, and this anxiety has been fed by the report of Karen Calhoun on the changing nature of the catalog. Calhoun (2006) suggests that the library community should abandon many of its expensive knowledge organization practices - such as the Library of Congress Subject Headings - in favor of integration of search engines into library catalogs. As logical as this seems on the face of it (and as much as we might often have wished LCSH would go away!), purveyors of such notions have either forgotten or rejected the notion of the library as a social instrument, and therefore the order of things in libraries as an extension of that social role. We must also view knowledge organization then as a cultural enterprise, a social act that has consequences. The ontologies we use to devise categorical schemes imply certain realities. If we say there is no music other than Western Art, why, then there must be no point in paying any attention to music of any other sort, right? And if we say that UFOs are a kind of controversial knowledge, we join the community of non-believers who insist that UFOs do not exist. Surely if we thought they were viable phenomena we would create a concrete class for them (see DDC 001.942). Voila, now we know, UFOs do not exist - the DDC says so. And if a gay adolescent searches for literature to help understand and finds that it all falls under "perversion" then we have oppressed yet another youth (see Campbell 2001). Our actions have social consequences.

Abstract

The fundamental principle of order in the library catalogue is the authorship principle, which serves as the organizing node of an alphabetico-classed system, in which "texts" of "works" are organized first alphabetically by uniform title of the progenitor work and then are subarranged using titles for variant instantiations, under the heading for an "author." We analyze case studies of entries from (1) the first documented imperial library catalogue, the Seven Epitomes (Qilue [??]), in China; (2) Abelard's Works, which featured prominently in the 1848 testimony of Antonio Panizzi; and (3) The French Chef and the large family of instantiated works associated with it. Our analysis shows that the catalogue typically contains many large superwork sets. A more pragmatic approach to the design of catalogues is to array descriptions of resources in relation to the superwork sets to which they might belong. In all cases, a multidimensional faceted arrangement incorporating ideational nodes from the universe of recorded knowledge holds promise for greatly enhanced retrieval capability.

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

There is greater depth in knowledge organization systems beyond the surface of hierarchically-structured concepts. Deconstructed elements of a knowledge organization system share network-like relationships that might be used in interaction with the characteristics of documents to provide "classification interaction" as a means of identifying previously undiscovered relationships. A random sample of UDC call numbers from the online catalog of the Catholic University of Leuven (KU Leuven) is analyzed to discover interactions among conceptual classification, instantiation, and bibliographic demographic characteristics. The associations demonstrated represent ways in which predictable interactions occur among classified bibliographic entities and the components of the rich UDC classification.

Abstract

Metadata schemes target resources as information-packages, without attention to the distinction between content and carrier. Most schema are derived without empirical understanding of the concepts that need to be represented, the ways in which terms representing the central concepts might best be derived, and how metadata descriptions will be used for retrieval. Research is required to resolve this dilemma, and much research will be required if the plethora of schemes that already exist are to be made efficacious for resource description and retrieval. Here I report the results of a preliminary study, which was designed to see whether the bibliographic concept of "the work" could be of any relevance among artifacts held by a museum. I extend the "works metaphor" from the bibliographic to the artifactual domain, by altering the terms of the definition slightly, thus: 1) instantiation is understood as content genealogy. Case studies of Etruscan artifacts from the University of Pennsylvania Museum of Archaeology and Anthropology are used to demonstrate the inherence of the work in non-documentary artifacts.

Abstract

From a historical perspective, one could consider the modern library catalog to be that bibliographical apparatus that stretches at least from Thomas Hyde's catalog for the Bodleian Library at Oxford to the near present. Mai and other recent authors have suggested postmodern approaches to knowledge organization. In these, we realize that there is no single and unique order of knowledge or documents but rather there are many appropriate orders, all of them contextually dependent. Works (oeuvres, opera, Werke, etc.), as are musical works, literary works, works of art, etc., are and always have been key entities for information retrieval. Yet catalogs in the modern era were designed to inventory (first) and retrieve (second) specific documents. From Hyde's catalog for the Bodleian until the late twentieth century, developments are epistemologically pragmatic--reflected in the structure of catalog records, in the rules for main entry headings, and in the rules for filing in card catalogs. After 1980 developments become empirical-reflected in research conducted by Tillett, Yee, Smiraglia, Leazer, Carlyle, and Vellucci. The influence of empiricism on the pragmatic notion of "the work" has led to increased focus on the concept of the work. The challenge for the postmodern online catalog is to fully embrace the concept of "the work," finally to facilitate it as a prime objective for information retrieval.

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.

Abstract

Research information can be useful to science stake-holders for discovering, evaluating and planning research activities. In the Netherlands, the institute tasked with the stewardship of national research information is DANS (Data Archiving and Networked Services). DANS is the home of NARCIS, the national portal for research information, which uses a similarly named national research classification. The NARCIS Classification assigns symbols to represent the knowledge bases of contributing scholars. A recent research stream in knowledge organization known as comparative classification uses two or more classifications experimentally to generate empirical evidence about coverage of conceptual content, population of the classes, and economy of classification. This paper builds on that research in order to further understand the comparative impact of the NARCIS Classification alongside a classification designed specifically for information resources. Our six cases come from the DANS project Knowledge Organization System Observatory (KOSo), which itself is classified using the Information Coding Classification (ICC) created in 1982 by Ingetraut Dahlberg. ICC is considered to have the merits of universality, faceting, and a top-down approach. Results are exploratory, indicating that both classifications provide fairly precise coverage. The inflexibility of the NARCIS Classification makes it difficult to express complex concepts. The meta-ontological, epistemic stance of the ICC is apparent in all aspects of this study. Using the two together in the DANS KOS Observatory will provide users with both clarity of scientific positioning and ontological relativity.

Yet catalogs in the modern era were designed to inventory (first) and retrieve (second) specific documents. From Hyde's catalog for the Bodleian until the late twentieth century, developments are epistemologically pragmatic--reflected in the structure of catalog records, in the rules for main entry headings, and in the rules for filing in card catalogs. After 1980 developments become empirical-reflected in research conducted by Tillett, Yee, Smiraglia, Leazer, Carlyle, and Vellucci. The influence of empiricism on the pragmatic notion of "the work" has led to increased focus on the concept of the work. The challenge for the postmodern online catalog is to fully embrace the concept of "the work," finally to facilitate it as a prime objective for information retrieval.

Perception is a crucial element in the viability of any knowledge organization system because it acts as a filter that provides contextual information about phenomena, including potential categorical membership. Perception is moderated culturally, but "social" systems exercise little or no cultural conformity. "Every day classification" is rife throughout human experience; but classification arises as a system of formal constraints that embody cultural assumptions about the categories that are the products of human cognition. Noesis is a perceptual component of Husserl's phenomenological approach to human experience. How we perceive a thing is filtered by our experiential feelings about it. The purpose of this research is to increase understanding of the role of cognition in every day classification by developing a fuller profile of perception. Photographs of mailboxes (a mundane, every-day example) from different locales are compared to demonstrate the noetic process. Tag clouds are analyzed to demonstrate the kinds of perceptual differences that suggest different user perceptions among those contributing tags.

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

The cataloging and classification community was called to highlight 2010 as "The Year of Cataloging Research," and specifically was challenged to generate research ideas, conduct research, and generally promote the development of new research in cataloging. Cataloging & Classification Quarterly has become the most influential journal of research in cataloging and classification since its inception in 1981. The idea behind the research reported here was to give the CCQ editorial board an opportunity to present its point of view about research for cataloging. A Delphi study was conducted in three stages during the 2009-2010 academic year. Members were asked to define the key terms "cataloging," "evidence," and "research," and to develop a research agenda in cataloging. The results reveal a basic core definition of cataloging perceived as a dynamic, active process at the core of information retrieval. An eight point research agenda emerges that is forward-looking and embraces change, along with top-ranked calls for new empirical evidence about catalogs, cataloging, and catalog users.

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.
