Abstract

Classification structure and indexes to classifications need to be better understood before classification can be a major access point in online catalogs.

Abstract

A fascinating, broad-ranging article about classification, knowledge, and how they relate. Hierarchies, trees, paradigms (a two-dimensional classification that can look something like a spreadsheet), and facets are covered, with descriptions of how they work and how they can be used for knowledge discovery and creation. Kwasnick outlines how to make a faceted classification: choose facets, develop facets, analyze entities using the facets, and make a citation order. Facets are useful for many reasons: they do not require complete knowledge of the entire body of material; they are hospitable, flexible, and expressive; they do not require a rigid background theory; they can mix theoretical structures and models; and they allow users to view things from many perspectives. Facets do have faults: it can be hard to pick the right ones; it is hard to show relations between them; and it is difficult to visualize them. The coverage of the other methods is equally thorough and there is much to consider for anyone putting a classification on the web.

Abstract

The Wolverhampton Web Library (WWLib) is a WWW search engine that provides access to UK based information. The experimental version developed in 1995, was a success but highlighted the need for a much higher degree of automation. An interesting feature of the experimental WWLib was that it organised information according to DDC. Discusses the advantages of classification and describes the automatic classifier that is being developed in Java as part of the new, fully automated WWLib

Abstract

The knowledge structures that form traditional library classification schemes hold great potential for improving resource description and discovery on the Internet and for organizing electronic document collections. The advantages of assigning subject tokens (classes) to documents from a scheme like the DDC system are well documented

Abstract

Potential uses for classification data in machine readable form and reasons for the development of a standard, the USMARC Format for Classification Data, which allows for classification data to interact with other USMARC bibliographic and authority data are discussed. The development, structure, content, and use of the standard is reviewed with implementation decisions for the Library of Congress Classification scheme noted. The author examines the implementation of USMARC classification at LC, the conversion of the schedules, and the functionality of the software being used. Problems in the effort are explored, and enhancements desired for the online classification system are considered.

Abstract

Library classification is constantly being influenced by multifaceted, multidimensional, and infinite growth of literature on one hand and the users needs on the other. Dewey pioneered in devising a scheme of classification for the documentation utility of the organised knowledge. Subsequent schemes of classification worked purely without any theoretical foundation, colon classification being the exception. With the emergence of computer technology the library classification is being metamorphised. This paper attempts to delve a state-of-the-art of library classification in the new computer age.

Abstract

Classification numbers and shelf marks may be useful in online searching. Ways of using classification in online searching include: direct classification searching; use of classification as linking devices or pivots; and direct or indirect searching of classification schedules and indexes. Discusses each of these techniques, mainly in the context of library OPAC searching although they may be applied to other types of online retrieval systems. The use of classification numbers as pivots enabling online searchers to retrieve related references by means of automation searching of identical or related classification numbers is reviewed with reference to the OKAPI project; BLCMP project and the DDC online project

Abstract

The paper reviews the development of the USMARC Format for Classification Data, a standard for communication of classification data in machine-readable form. It considers the uses for online classification schedules, both for technical services and reference functions and gives an overview of the format specification details of data elements used and of the structure of the records. The paper describes an experiment conducted at the Library of Congress to test the format as well as the development of the classification database encompassing the LCC schedules. Features of the classification system are given. The LoC will complete its conversion of the LCC in mid-1995

Abstract

It will not be an easy task to automate the Library of Congress Classification schedules because it is a very large system and also because it developed long before automation. The designers were creating a system for shelving books effiently and had not even imagined the constraints imposed by automation. A number of problems and possible solutions are discussed. The MARC format proposed for classification has some serious problems which are identified

Abstract

This paper discusses the newly developed USMARC Format for Classification Data. It reviews its potential uses within an online system and its development as one of the USMARC standards for representing bibliographic and related information in machine-readable form. It provides a summary of the fields in the format, and considers the prospects for its implementation.

Abstract

This paper describes the features of Electronic Dewey bringing out the ways in which it differs from the printed version of the Classification. The various search techniques available are discussed and the use of the DDC functions is considered. The paper concludes that while improvements could be made the CD-ROM heralds the electronic age of classification.

Abstract

System design options and user searching options are discussed. The problems of electronic union catalogs, including a 'virtual union catalog' in particular are considered and enhancements made possible through classification are explored. The combined system of subject headings and classification is presented as the model of the integrated subject searching tool which will meet individualized learning styles and user responsive vocabulary

Abstract

Argues that classification systems have an important role to play in knowledge organization in the new world electronic order. The natural language approach is not incompatible with the use of a classification system and classification has untapped potential as a multilingual switching language. Librarians must learn to present classification systems in a language understood by a general audience and promote them as general knowledge organization tools

Abstract

Advantages and disadvantages of on-line classification access are presented with special attention to Library of Congress Classification (LCC) features for subject browsing, known item-searching, enhancement of keyword and controlled vocabulary searching, and other unique retrieval capabilities.
