Melvil Deweyâ s Ingenious Notational System

Green, Rebecca January 2009 (has links)
Historically, the notational system of the Dewey Decimal Classification provided for non-institution-specific, relative location shelf arrangements, thus substantially reducing bibliographic classification effort. Today its decimal notation continues to provide the classification scheme with flexible granularity, is hospitable to expansion, expresses relationships, interfaces well with modern retrieval systems, and is internationally understood.

Status of Health Information Classification for Consumer Information Retrieval

Whetstone, Melinda January 2007 (has links)
With a growing movement toward patient-centric health care and patient empowerment, consumers are encouraged to take an active role in their health care. In fact, nearly 80% of Americans are taking to the Internet to search for health information (Fox, 2006). In addition to the Internet, consumers have access to a growing number of health search engines and professional biomedical databases via health science libraries. However, the consumer’s ability to efficiently retrieve information that is understandable and pertinent to their query is hindered (Volk, 2007) for reasons that include inexperience with “technical terminology,” (Zeng & Tse, 2006) and poor database usability (Smith, 2007). Several organizations are engaged in efforts to refine capabilities to match consumer health queries with accurate information (Smith, 2007; Zeng & Tse, 2006; Zeng et al., 2006). However, as more consumers seek health information in this growing empowered climate and more information is made available, there is an increasing danger that the consumer will become more confused and less able to find pertinent information. This paper explores three areas: it examines the current biomedical ontologies that are used for consumer health searches; it looks at the current means for health information retrieval (IR); and it explores ongoing projects that serve to improve consumer search capabilities. To evaluate the effects of multiple ontologies and search methods, a consumer’s health query was posed using several health search methods.

Enhancement of UDC data for use and sharing in a networked environment: [presentation at the Librarian Workshop in conjunction with "The 31st Annual Conference of the German Classification Society on Data Analysis, Machine Learning, and Applications", March 7-9, 2007, Freiburg i. Br., Germany]

Slavic, Aida, Cordeiro, Maria Inês, Riesthuis, Gerhard January 2007 (has links)
The authors give an overview of the present context of the development and use of Universal Decimal Classification (UDC) and describe the current work towards enrichment and improvement of the UDC data. UDC is a classification system used worldwide for organization and information access in various kinds of collections and information services. From 1993 UDC has been available for distribution to publishers and users as a database file which has initially improved the classification's potential for online use. From 1993 to 2007 the UDC vocabulary has been extensively revised and 14 updated UDC files have been distributed, on an annual basis. In order to take full advantage of this electronic availability, new developments should be carried out to support a better alignment between the forms and formats in which the UDC scheme is distributed and the classification's practical use in networked information services. The authors discuss different aspects that may concur with this aim, at the data structure, data content and data transmission levels. Examples include the possible provision of: an enhanced UDC data format; UDC multilingual data and UDC mappings to other subject indexing systems; UDC data exports in various other data formats that can be easily implemented, updated, shared or exchanged. In this context, a summary of current initiatives of the UDC Consortium is provided, notably in terms of renovation of the UDC technological management.

Performance tags -- who's running the show?

Tonkin, Emma, Tourte, Gregory J. L., Zollers, Alla January 2008 (has links)
We describe a pilot study which specifically examines the prevalence and characteristics of performance tags on several sites. Identifying post-coordination of tags as a useful step in the study of this phenomenon, as well as other approaches to leveraging tags based on text and/or sentiment analysis, we demonstrate an approach to automation of this process, postcoordinating (segmenting) terms by means of a probabilistic model based around Markov chains. The effectiveness of this approach to parsing is evaluated with respect to the wide range of constructions visible on various services. Several candidate approaches for the latter stages of automated classification are identified.

Archaeology and the structure of class 9

Chovanova, Katarina 12 1900 (has links)
Despite the intensive revision carried out in the past two decades, there are still some outdated parts of UDC in need of attention. Although new terminology may be added on a more specific subject level, the outdated and illogical structure of the top classes in class 9 stands out. The work on recent extensions of class 94 History has reminded us of what is still wrong in the class 9.

Exploring classification as conversation

Pimentel, David M. January 2007 (has links)
Conversations are proposed as a useful lens through which to consider knowledge-organizing behaviors. Human conversations are sites of knowledge creation, where participants communicate to establish meaning that is contextual and shared. The conversations generated in collaborative online environments offer new opportunities to observe, not only how knowledge is created, but also how users participate in various knowledge-organizing activities. In a Web environment pervaded by conversational forms â social classification systems, blogs, and wikis â participatory knowledge organization is an emerging phenomenon that warrants further exploration. Other areas for research are suggested, including the potential promise to leverage participatory knowledge organization into future applications and developments of Web functionality.

The UDC Philosophy revision project

Gnoli, Claudio, Mazzocchi, Fulvio, Slavic, Aida 12 1900 (has links)
The UDC class 1 Philosophy. Psychology has remained unchanged for more than forty years. The most obvious problem with the class is an anachronistic intercalation of psychology in the middle of the class of philosophy (Task force for UDC system development, 1990), one of the still uncorrected remainders of structural problems inherited from Dewey Decimal Classification. We are now pleased to announce that the project of the revision of UDC class 1 Philosophy will take place in 2009-2010.

Classification of Keywords Extracted from Research Articles Published in Science Journals

Dutta, Bidyarthi, Majumder, Krishnapada, Sen, B. K. 12 1900 (has links)
This paper is based on an analytical study of 335 keywords extracted from titles and abstracts of 70 research articles, taking ten from each year starting from 2000 to 2006, in decreasing order of relevance, on the subject Fermi Liquid, which is a specific subject under the broad area of Condensed Matter Physics. The research articles have been collected from the bibliographic database of INSPEC. The keywords are indexed to critically examine its physical structure that is composed of three fundamental kernels, viz. keyphrase, modulator and qualifier. The keyphrase reflects the central concept, which is usually post-coordinated by the modulator to amend the central concept in accordance with the relevant context. The qualifier comes after the modulator to describe the particular state of the central concept and/or amended concept. The keywords are further classified in 16 classes on the basis of the four parameters, viz. Associativeness, chronological appearance, frequency of occurrence and category. The taxonomy of keywords will enable to analyze research-trend of a subject and to identify potential research-areas of a subject.

UDC Seminar 2007 "Information Access to the Global Community": summary and conclusions

McIlwaine, Ia C, January 2007 (has links)
Proceedings of the UDC Seminar 2007 were published as an Annex of the Extensions and Corrections to the UDC journal, number 29 (2007) / When we were planning this conference our intention was to host an event that would give the classification a higher profile, update our users to what was going on, suggest innovations that might be considered and provide an opportunity for the interchange of ideas and discussion so that participants could share their experiences and voice their needs. We also would like to attract more people to participate in the work of the classification, either by joining the Consortium under one of the different forms of membership, such as full member, associate or individual or by volunteering assistance on the constant work of updating the classification. The first part of this intention has, I think, been well fulfilled and I hope that the second will follow as a result of it. ...

UDC in Lithuania

Norekiene, Dalia 12 1900 (has links)
In 1991, the first UDC schedules in Lithuanian language were published as an abridged UDC edition adapted for Lithuanian public libraries. In the period 1992-1993 separate fascicles of complete Russian UDC tables continued to be translated, adapted and published for Lithuanian libraries. As the need for a standard Lithuanian edition has become more apparent, the Lithuanian National Library started preparation of the new edition in 1995. At the time of this report more than 64,000 classes of the UDC MRF database have been translated into Lithuanian; several volumes of the new Lithuanian edition have already been published and others are in preparation.
