Abstract

Networked orientated standards for vocabulary publishing and exchange and proposals for terminological services and terminology registries will improve sharing and use of all knowledge organization systems in the networked information environment. This means that documentary classifications may also become more applicable for use outside their original domain of application. The paper summarises some characteristics common to documentary classifications and explains some terminological, functional and implementation aspects. The original purpose behind each classification scheme determines the functions that the vocabulary is designed to facilitate. These functions influence the structure, semantics and syntax, scheme coverage and format in which classification data are published and made available. The author suggests that attention should be paid to the differences between documentary classifications as these may determine their suitability for a certain purpose and may impose different requirements with respect to their use online. As we speak, many classifications are being created for knowledge organization and it may be important to promote expertise from the bibliographic domain with respect to building and using classification systems.

Rez. in: Knowledge organization 30(2003) no.1, S.40-42 (J.-E. Mai): "Introduction: This is a collection of papers presented at the National Seminar an Classification in the Digital Environment held in Bangalore, India, an August 9-11 2001. The collection contains 18 papers dealing with various issues related to knowledge organization and classification theory. The issue of transferring the knowledge, traditions, and theories of bibliographic classification to the digital environment is an important one, and I was excited to learn that proceedings from this seminar were available. Many of us experience frustration an a daily basis due to poorly constructed Web search mechanisms and Web directories. As a community devoted to making information easily accessible we have something to offer the Web community and a seminar an the topic was indeed much needed. Below are brief summaries of the 18 papers presented at the seminar. The order of the summaries follows the order of the papers in the proceedings. The titles of the paper are given in parentheses after the author's name. AHUJA and WESLEY (From "Subject" to "Need": Shift in Approach to Classifying Information an the Internet/Web) argue that traditional bibliographic classification systems fall in the digital environment. One problem is that bibliographic classification systems have been developed to organize library books an shelves and as such are unidimensional and tied to the paper-based environment. Another problem is that they are "subject" oriented in the sense that they assume a relatively stable universe of knowledge containing basic and fixed compartments of knowledge that can be identified and represented. Ahuja and Wesley suggest that classification in the digital environment should be need-oriented instead of subjectoriented ("One important link that binds knowledge and human being is his societal need. ... Hence, it will be ideal to organise knowledge based upon need instead of subject." (p. 10)).
AHUJA and SATIJA (Relevance of Ranganathan's Classification Theory in the Age of Digital Libraries) note that traditional bibliographic classification systems have been applied in the digital environment with only limited success. They find that the "inherent flexibility of electronic manipulation of documents or their surrogates should allow a more organic approach to allocation of new subjects and appropriate linkages between subject hierarchies." (p. 18). Ahija and Satija also suggest that it is necessary to shift from a "subject" focus to a "need" focus when applying classification theory in the digital environment. They find Ranganathan's framework applicable in the digital environment. Although Ranganathan's focus is "subject oriented and hence emphasise the hierarchical and linear relationships" (p. 26), his framework "can be successfully adopted with certain modifications ... in the digital environment." (p. 26). SHAH and KUMAR (Model for System Unification of Geographical Schedules (Space Isolates)) report an a plan to develop a single schedule for geographical Subdivision that could be used across all classification systems. The authors argue that this is needed in order to facilitate interoperability in the digital environment. SAN SEGUNDO MANUEL (The Representation of Knowledge as a Symbolization of Productive Electronic Information) distills different approaches and definitions of the term "representation" as it relates to representation of knowledge in the library and information science literature and field. SHARADA (Linguistic and Document Classification: Paradigmatic Merger Possibilities) suggests the development of a universal indexing language. The foundation for the universal indexing language is Chomsky's Minimalist Program and Ranganathan's analytico-synthetic classification theory; Acording to the author, based an these approaches, it "should not be a problem" (p. 62) to develop a universal indexing language.
SELVI (Knowledge Classification of Digital Information Materials with Special Reference to Clustering Technique) finds that it is essential to classify digital material since the amount of material that is becoming available is growing. Selvi suggests using automated classification to "group together those digital information materials or documents that are "most similar" (p. 65). This can be attained by using Cluster analysis methods. PRADHAN and THULASI (A Study of the Use of Classification and Indexing Systems by Web Resource Directories) compare and contrast the classificatory structures of Google, Yahoo, and Looksmart's directories and compare the directories to Dewey Decimal Classification, Library of Congress Classification and Colon Classification's classificatory structures. They find differentes between the directories' and the bibliographic classification systems' classificatory structures and principles. These differentes stem from the fact that bibliographic classification systems are used to "classify academic resources for the research community" (p. 83) and directories "aim to categorize a wider breath of information groups, entertainment, recreation, govt. information, commercial information" (p. 83). NEELAMEGHAN (Hierarchy, Hierarchical Relation and Hierarchical Arrangement) reviews the concept of hierarchy and the formation of hierarchical structures across a variety of domains. NEELAMEGHAN and PRADAD (Digitized Schemes for Subject Classification and Thesauri: Complementary Roles) demonstrate how thesaural relationships (NT, BT, and RT) can be applied to a classification scheme, the Colon Classification in this Gase. NEELAMEGHAN and ASUNDI (Metadata Framework for Describing Embodied Knowledge and Subject Content) propose to use the Generalized Facet Structure framework which is based an Ranganathan's General Theory of Knowledge Classification as a framework for describing the content of documents in a metadata element set for the representation of web documents. CHUDAMANI (Classified Catalogue as a Tool for Subject Based Information Retrieval in both Traditional and Electronic Library Environment) explains why the classified catalogue is superior to the alphabetic cata logue and argues that the same is true in the digital environment.
Discussion The proceedings of the National Seminar an Classification in the Digital Environment give some insights. However, the depth of analysis and discussion is very uneven across the papers. Some of the papers have substantive research content while others appear to be notes used in the oral presentation. The treatments of the topics are very general in nature. Some papers have a very limited list of references while others have no bibliography. No index has been provided. The transfer of bibliographic knowledge organization theory to the digital environment is an important topic. However, as the papers at this conference have shown, it is also a difficult task. Of the 18 papers presented at this seminar an classification in the digital environment, only 4-5 papers actually deal directly with this important topic. The remaining papers deal with issues that are more or less relevant to classification in the digital environment without explicitly discussing the relation. The reason could be that the authors take up issues in knowledge organization that still need to be investigated and clarified before their application in the digital environment can be considered. Nonetheless, one wishes that the knowledge organization community would discuss the application of classification theory in the digital environment in greater detail. It is obvious from the comparisons of the classificatory structures of bibliographic classification systems and Web directories that these are different and that they probably should be different, since they serve different purposes. Interesting questions in the transformation of bibliographic classification theories to the digital environment are: "Given the existing principles in bibliographic knowledge organization, what are the optimum principles for organization of information, irrespectively of context?" and "What are the fundamental theoretical and practical principles for the construction of Web directories?" Unfortunately, the papers presented at this seminar do not attempt to answer or discuss these questions."

Abstract: Internet information retrieval is largely the preserve of search engines and the even more popular subject trees. Subject trees have adapted principles of conventional bibliographic classification for structuring hierarchic browsing interfaces, thus providing easily used pathways to their selected resources. This combination of browsing and selectivity is especially valuable to untrained users. For the forseeable future, it appears that subject trees will remain the Internet's only practicable use of classificatory methods for information retrieval

Abstract

Possibilities are being explored to use traditional bibliographic tools, like Dewey Decimal Classification (DDC), Library of Congress Classification (LCC), Library of Congress Subject Headings (LCSH), and Universal Decimal Classification (UDC), to improve the organization of information resources on the Internet. The most recent edition of DDC, with its enhanced features, has greater potential than other traditional approaches. A review of selected Web sites that use DDC to organize Web resources indicates, however, that the full potential of the DDC scheme for this purpose has not been realized. While the review found that the DDC classification structure was more effective when compared with other knowledge organization systems, we conclude that DDC needs to be further enhanced to make it more suitable for this application. As widely reported in the professional literature, OCLC has conducted research on the potential of DDC for organizing Web resources. Such research, however, is experimental and should be supplemented by empirical studies with user participation.

Abstract

This paper examines the differences in the functional requirements of a faceted classification system when used in a conventional print-based environment (where the emphasis is on the browse function of the classification) as compared to its application to digital collections (where the retrieval function is paramount). The use of the second edition of Bliss's Bibliographic Classification (BC2) as a general classification for the physical organization of undergraduate collections in the University of Cambridge is described. The development of an online tool for indexing of digital resources using the Bliss terminologies is also described, and the advantages of facet analysis for data structuring and system syntax within the prototype tool are discussed. The move from the print-based environment to the digital makes different demands an both the content and the syntax of the classification, and while the conceptual structure remains similar, manipulation of the scheme and the process of content description can be markedly different.

Abstract

Broughton is one of the key people working on the second edition of the Bliss Bibliographic Classification (BC2). Her article has a brief, informative history of facets, then discusses semantic vs. syntactic relationships, standard facets used by Ranganathan and the Classification Research Group, facet analysis and citation order, and how to build subject indexes out of faceted classifications, all with occasional reference to digital environments and hypertext, but never with any specifics. It concludes by saying of faceted classification that the "capacity which it has to create highly sophisticated structures for the accommodation of complex objects suggests that it is worth investigation as an organizational tool for digital materials, and that the results of such investigation would be knowledge structures of unparalleled utility and elegance." How to build them is left to the reader, but this article provides an excellent starting point. It includes an example that shows how general concepts can be applied to a small set of documents and subjects, and how terms can be adapted to suit the material and users

Abstract

This is a short, but very thorough and very interesting, report on how the writers built a faceted classification for some legal information and used it to structure a web site with navigation and searching. There is a good summary of why facets work well and how they fit into bibliographic control in general. The last section is about their implementation of a web site for the Washington State Bar Association's Council for Legal Public Education. Their classification uses three facets: Purpose (the general aim of the document, e.g. Resources for K-12 Teachers), Topic (the subject of the document), and Type (the legal format of the document). See Example Web Sites, below, for a discussion of the site and a problem with its design.

Abstract

The paper analyses the importance of data presentation and modelling and its role in improving the management, use and exchange of analytico-synthetic classifications in automated systems. Inefficiencies, in this respect, hinder the automation of classification systems that offer the possibility of building compound index/search terms. The lack of machine readable data expressing the semantics and structure of a classification vocabulary has negative effects on information management and retrieval, thus restricting the potential of both automated systems and classifications themselves. The authors analysed the data representation structure of three general analytico-synthetic classification systems (BC2-Bliss Bibliographic Classification; BSO-Broad System of Ordering; UDC-Universal Decimal Classification) and put forward some core requirements for classification data representation

Abstract

In the present work we discuss opportunities, problems, tools and techniques encountered when interconnecting discipline-specific subject classifications, primarily organized as search devices in bibliographic databases, with general classifications originally devised for book shelving in public libraries. We first state the fundamental distinction between topical (or subject) classifications and object classifications. Then we trace the structural limitations that have constrained subject classifications since their library origins, and the devices that were used to overcome the gap with genuine knowledge representation. After recalling some general notions on structure, dynamics and interferences of subject classifications and of the objects they refer to, we sketch a synthetic overview on discipline-specific classifications in Mathematics, Computing and Physics, on one hand, and on general classifications on the other. In this setting we present The Scientific Classifications Page, which collects groups of Web pages produced by a pool of software tools for developing hypertextual presentations of single or paired subject classifications from sequential source files, as well as facilities for gathering information from KWIC lists of classification descriptions. Further we propose a concept-oriented methodology for interconnecting subject classifications, with the concrete support of a relational analysis of the whole Mathematics Subject Classification through its evolution since 1959. Finally, we recall a very basic method for interconnection provided by coreference in bibliographic records among index elements from different systems, and point out the advantages of establishing the conditions of a more widespread application of such a method. A part of these contents was presented under the title Mathematics Subject Classification and related Classifications in the Digital World at the Eighth International Conference Crimea 2001, "Libraries and Associations in the Transient World: New Technologies and New Forms of Cooperation", Sudak, Ukraine, June 9-17, 2001, in a special session on electronic libraries, electronic publishing and electronic information in science chaired by Bernd Wegner, Editor-in-Chief of Zentralblatt MATH.

Abstract

The Library of Congress Subject Headings schema (LCSH) is by far the most commonly used and widely accepted subject vocabulary for general application. It is the de facto universal controlled vocabulary and has been a model for developing subject heading systems by many countries. However, LCSH's complex syntax and rules for constructing headings restrict its application by requiring highly skilled personnel and limit the effectiveness of automated authority control. Recent trends, driven to a large extent by the rapid growth of the Web, are forcing changes in bibliographic control systems to make them easier to use, understand, and apply, and subject headings are no exception. The purpose of adapting the LCSH with a simplified syntax to create FAST is to retain the very rich vocabulary of LCSH while making the schema easier to understand, control, apply, and use. The schema maintains upward compatibility with LCSH, and any valid set of LC subject headings can be converted to FAST headings.

"Am 16. August 2005 fand in Oslo im Rahmen der heurigen IFLA-Konferenz das alljährliche Treffen der DDC-Übersetzer und der weltweiten DeweyAnwender-Institutionen (Nationalbibliotheken, Ersteller von Nationalbibliografien) statt. Die im Sommer 2005 bereits abgeschlossene deutsche Übersetzung wird in der Druckfassung Ende des Jahres in 4 Bänden vorliegen, beim K. G. Saur Verlag in München erscheinen (ISBN 3-598-11651-9) und 2006 vom ebenfalls erstmals ins Deutsche übersetzten DDC-Lehrbuch (ISBN 3-598-11748-5) begleitet. Pläne für neu startende Übersetzungen der DDC 22 gibt es für folgende Sprachen: Arabisch (mit der wachsenden Notwendigkeit, Klasse 200 Religion zu revidieren), Französisch (es erschien zuletzt eine neue Kurzausgabe 14, nun werden eine vierbändige Druckausgabe und eine frz. Webversion anvisiert), Schwedisch, Vietnamesisch (hierfür wird eine an die Sprache und Schrift angepasste Version des deutschen Übersetzungstools zum Einsatz kommen).
Allgemein DDC 22 ist im Gegensatz zu den früheren Neuauflagen der Standard Edition eine Ausgabe ohne generelle Überarbeitung einer gesamten Klasse. Sie enthält jedoch zahlreiche Änderungen und Expansionen in fast allen Disziplinen und in vielen Hilfstafeln. Es erschien auch eine Sonderausgabe der Klasse 200, Religion. In der aktuellen Kurzausgabe der DDC 22 (14, aus 2004) sind all diese Neuerungen berücksichtigt. Auch die elektronische Version exisitiert in einer vollständigen (WebDewey) und in einer KurzVariante (Abridged WebDewey) und ist immer auf dem jüngsten Stand der Klassifikation. Ein Tutorial für die Nutzung von WebDewey steht unter www.oclc.org /dewey/ resourcesitutorial zur Verfügung. Der Index enthält in dieser elektronischen Fassung weit mehr zusammengesetzte Notationen und verbale Sucheinstiege (resultierend aus den Titeldaten des "WorldCat") als die Druckausgabe, sowie Mappings zu den aktuellsten Normdatensätzen aus LCSH und McSH. Aktuell Die personelle Zusammensetzung des EPC (Editorial Policy Committee) hat sich im letzten Jahr verändert. Dieses oberste Gremium der DDC hat Prioritäten für den aktuellen Arbeitsplan festgelegt. Es wurde vereinbart, größere Änderungsvorhaben via Dewey-Website künftig wie in einem Stellungnahmeverfahren zur fachlichen Diskussion zu stellen. www.oclc.org/dewey/discussion/."
