James Duff Brown's Subject Classification and Evaluation Methods for Classification Systems

Beghtol, Clare January 2004 (has links)
James Duff Brown (1862-1914), an important figure in librarianship in late nineteenth and early twentieth century England, made contributions in many areas of his chosen field. His Subject Classification (SC), however, has not received much recognition for its theoretical and practical contributions to bibliographic classification theory and practice in the twentieth century. This paper discusses some of the elements of SC that both did and did not inform future bibliographic classification work, considers some contrasting evaluation methods in the light of advances in bibliographic classification theory and practice and of commentaries on SC, and suggests directions for further research.

Tagging for Health Information Organisation and Retrieval

Kipp, Margaret E. I. January 2007 (has links)
INTRODUCTION Medical professionals seek to capture papers which can be located via keyword or free text search in digital libraries or on the web but are also interested in finding material that has not yet been indexed in on-line databases. Search engines provide a multitude of results [1]. Social bookmarking, where users tag items for their own use, offers a way to locate new and relevant information. CiteULike (citeulike.org), a social bookmarking service, allows articles to be tagged with useful keywords for later retrieval. RELATED STUDIES A previous study [2] compared social bookmarking to existing information organisation structures and found similarities in terminology use and intriguing differences. A sample of articles tagged on CiteULike was examined for contextual differences in keyword usage between users of social bookmarking sites, authors and indexers. Many tags were related to thesaurus terms (descriptors), but were not formally in the thesaurus. [2] This study examines how term usage patterns in tags, keywords and descriptors suggest a similar (or differing) context between users, authors and intermediaries. METHODOLOGY This study examines the use of tags on CiteULike from three medical or biology journals (JAMA, Proteins, and Journal of Molecular Biology) indexed in Pubmed. 1299 unique articles were retrieved from Citeulike; Medical Subject Headings (MeSH) were collected from Pubmed. Articles were analysed using standard informetric techniques to examine the use of user assigned tags and their Pubmed assigned MeSH index terms. Data was analysed for term usage and categorised to see what contextual clues users expose in their tag use. RESULTS Articles were tagged by up to 14 users (average 2-4). 1449 unique tags were used in the data set. Some articles were heavily tagged by users (max. 29, min. 1, median 2). Descriptors were more heavily assigned to articles (2746 unique descriptors). Articles had, on average, 10 descriptors assigned (max. 40, min. 2). Some tags occurred frequently: protein_structure (140), no-tag (134), and protein (114). By journal, tags were: docking (Proteins, 85), no-tag (JAMA, 20), and protein_structure (J Mol Biol, 52). No-tag (system assigned) indicated no tag assigned. Descriptors were more heavily reused than tags, for example: 'Models, Molecular' (550), Protein Conformation (363), and Humans (341). By journal, descriptors were: 'Models, Molecular' (Proteins, 252), 'Models, Molecular' (J Mol Biol, 235), and Humans (JAMA, 137). DISCUSSIONS AND CONCLUSIONS Comparison of tag and descriptor lists shows many of the same similarities and differences as the previous study [2]. Many user terms were related to the author and intermediary terms but not in the thesaurus (e.g. 'diet' and 'fat' used separately in the tag lists where they were linked as 'dietary fats' in the thesaurus). Terms such as 'human' and 'family-studies' show users tagging biology articles are interested in methodology and user groups associated with articles. This study has system design implications for accessing, indexing and searching document spaces. Users express frustration trying to narrow search results. Controlled vocabularies help narrow a search to a manageable size but can be expensive. User tagging could provide additional access points to traditional controlled vocabularies and the associative classifications necessary to tie documents and articles to time and task relationships among other novel items.

Uncovering Hidden Clues about Geographic Visualization in LCC

Buchel, Olha January 2006 (has links)
Geospatial information technologies revolutionize the way we have traditionally approached navigation and browsing in information systems. Colorful graphics, statistical summaries, geospatial relationships of underlying collections make them attractive for text retrieval systems. This paper examines the nature of georeferenced information in academic library catalogs organized according to the Library of Congress Classification (LCC) with the goal of understanding their implications for geovisualization of library collections.

From Card Catalogues to WebPACs: Celebrating Cataloguing in the 20th Century

Gorman, Michael January 2000 (has links)
This keynote address recounts the many important accomplishments and advancements in cataloguing theory and practice which have occurred between 1900 and 1999, and provides a backdrop for the papers and discussions which presented in the Conference on Bibliographic Control in the New Millennium. The address also serves as an upbeat reminder of all the progress that has been made and, we hope, will inspire conference participants to tackle the challenges of networked resources and the Web with enthusiasm and resolve.

Naming, claiming, and (re)creating : Indigenous knowledge organization at the cultural interface

Doyle, Ann Mary 05 1900 (has links)
This design/research study is located at the disciplinary interstices of Indigenous education and information science. It is motivated by the weaknesses of the dominant library knowledge organization systems (KOS) in representing and organizing documents with Indigenous content. The study first examines the nature of the problem and then explores ways in which Indigenous conceptual, theoretical and methodological approaches can generate new directions for KOS design. It thereby addresses the central research question, “How can Indigenous approaches to knowledge inform principles of design of library knowledge organization systems to serve Indigenous purposes?” An Indigenous theoretical lens, @ Cultural Interface, is assembled for the study composed of Martin Nakata’s (2007b) Cultural Interface, and Dwayne Donald’s (2009b) Indigenous Métissage. It is integrated with domain analysis in information science (Hjørland & Albrechtsen, 1995) to produce a methodology, domain analysis @ Cultural Interface, used to study the domain of Indigenous knowledge within post-secondary education. Information was gathered through expert interviews with nine Indigenous designers of Indigenous KOS from four countries; a user study with nine First Nations, Aboriginal, and Métis graduate students; and theoretical analyses. The study produced a theoretical framework for Indigenous knowledge organization based on four main findings: (1) knowledge organization is integral to educational infrastructure and is consequential for Indigenous learners and all learners; (2) a definition of the domain of Indigenous knowledge in post-secondary education, its boundaries and the boundary marker of Indigeneity; (3) an articulation of Indigenous knowledge organization as a field of study including a (partial) history, typology of design practice, objectives, and evaluation framework; and (4) a design workspace for conceptual enquiry. These findings are synthesized in a theoretical framework, Indigenous knowledge organization @ Cultural Interface, which can be applied in the design, study, and critique of knowledge organization for Indigenous purposes. It is noted that this study and its theoretical framework have been constructed incrementally based on selected theorists, particular participants, experiences, and literatures and offer only one of many possible interpretations. / Education, Faculty of / Educational Studies (EDST), Department of / Graduate

Modulation and Specialization in North American Knowledge Organization: Visualizing Pioneers

Smiraglia, Richard P. January 2009 (has links)
Pioneers are those who, in some way, lead their peers to new destinations. In the evolution of a domain, the pioneers might very well be those who have followed a theoretical principle in some particularly ardent manner, thus leading the rest of the domain toward an evolving research front. The present paper is an attempt to use the tools of domain analysis to diachronically analyze the domain of knowledge organization as it is evolving in North America. That is we use bibliometric tools to identify the axes that define North American knowledge organization and its scientists, who are its pioneers. The evolution of a North American chapter of the International Society for Knowledge Organization (ISKO) marks a growth in coherence of a long active research area. An interesting research question is: what are the characteristics of North American scholarship in knowledge organization? Author co-citation analysis of North American authors whose work appeared in the journal Knowledge Organization is contrasted with author co-citation analysis of authors from outside North America. North American leaders are clearly identified, and some themesâ such as knowledge organization onlineâ that are emergent topics in North America are identified.

Exploring the Context of User, Creator and Intermediary Tagging

Kipp, Margaret E. I. 03 1900 (has links)
7th Information Architecture Summit, Vancouver, BC, March 23-27 / This paper examines the results of a study of the three groups involved in creating index keywords or tags: users, authors and intermediaries. Keywords from each of the three groups were compared to determine similarities and differences in term use. Comparisons suggested that there were important differences in the contexts of the three groups that should be taken into account when assigning keywords or designing systems for the organisation of information.

What a Subject Search Interface Can Do

Schallier, Wouter 12 1900 (has links)
K.U.Leuven University Library (Belgium) developed an experimental interface for subject search by UDC in the OPAC. The interface combines the search facilities of a classification with those of a word system, since it enables the end user to search by subject terms and to see these terms in the hierarchy of broader, parallel and more specific terms. This project should be seen as an important indication of the libraryâ s growing concern to present its information sources in a content-structured and user-friendly way. At the same time, it has to be situated in a new policy for knowledge organization, which aims to find a balance between the local and overall needs of a library network. Finally, this project comes at a moment when K.U.Leuven University Library is in full conversion to Aleph 500 software.

Towards the â webificationâ of controlled subject vocabulary: A case study involving the Dewey Decimal Classification

Panzer, Michael 09 1900 (has links)
The presentation was part of The 6th European Networked Knowledge Organization Systems (NKOS) Workshop at the 11th European Conference on Research and Advanced Technology for Digital Libraries (ECDL), Budapest, Hungary September 21, 2007 (http://www.comp.glam.ac.uk/pages/research/hypermedia/nkos/nkos2007/programme.html) / The presentation will briefly introduce a series of major principles for bringing subject terminology to the network level. A closer look at one KOS in particular, the Dewey Decimal Classification, should help to gain more insight into the perceived difficulties and potential benefits of building taxonomy services out and on top of classic large-scale vocabularies or taxonomies.

On the razor's edge: between local and overall needs in knowledge organization

Schallier, Wouter 07 1900 (has links)
This is a 27-slide presentation made at ISKO 2004 (International Society for Knowledge Organization) in London, UK. Recent projects in subject indexing and classification at K.U.Leuven University Library (Belgium) aim to give new impulses to knowledge organization within the institution. While in recent years a lot of attention was given, and with good reason, to the technical and administrative integration of e-sources, less energy was invested in organizing the content of traditional and electronic collections. Nevertheless, presenting information sources in a content-structured way remains a core task of our University Library. This paper focuses on some experiments with subject search interfaces at K.U.Leuven University Library and situates them in a new policy for knowledge organization, which tries to find a balance between local and overall needs.
