Abstract: Over the past 5 years, librarians, humanities computing researchers and computer scientists have been working to establish standards for encoding and accessing local and networked electronic information resources, and these are now being put into practice by their corresponding user communities. The OCLC Cataloging Internet Resources project is investigating the relationship between 2 of these: the MARC bibliographic format and the Text Encoding Initiative (TEI) header, developed by humanities computing researchers. Specifically, the project has designed a WWW based prototype, called Spectrum, that enables those without specialized knowledge of library cataloguing or markup to create records for describing and accessing Internet resources of various types. The system enables the generation of MARC records from TEI headers

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

Recent advances in automating library classification data are causing the makers and maintainers of DDC and LCC to seek enhancements to these schemes that will facilitate computer-assisted classifying and extend the usefulbess of library classification to electronic collections. To explore the kinds of improvements that are needed to ensure that classification remains a viable subject retrieval tool, DDC numbers applied to over 40.000 records for Internet-accessible resources were analyzed. This analysis is used as a springboard for recommendations for improvements to DDC and LCC

Abstract

Using subject headings for Online Retrieval is an indispensable tool for online system desingners who are developing new systems or refining exicting ones. The book describes subject analysis and subject searching in online catalogs, including the limitations of retrieval, and demonstrates how such limitations can be overcome through system design and programming. The book describes the Library of Congress Subject headings system and system characteristics, shows how information is stored in machine readable files, and offers examples of and recommendations for successful methods. Tables are included to support these recommendations, and diagrams, graphs, and bar charts are used to provide results of data analyses.

Abstract

Recognition, by libraries, of the need for improved efficiency and reliability in subject authority control in catalogues led to a study of the feasibility of automatically creating a subject heading validation file by scanning the OLUC. The premises were: that although the file would not be axhaustive, it would contain the majority of frequently used headings; and that the predicted level of accurary in the file would be high. A sample file of Library of Congress assigned subject headings, from the OCLC Subject Headings Corrections database was analyzed. Results showed that: the frequency of use varies inversely with the number of headings at a given rrate of use; a small number of headings with high frequencies of use accounts for the majority of total use, while a large proportion shows very low frequency of use; topical headings account for 2/3 of assigned headings; and error and obsolescence rates are both low and are in inverse relationship to the frequency of heading use. Concludes that an automatically generated subject heading validation file is feasible and could serve various purposes, including: verification of subject heading strings constructed by cataloguers; updating of subject headings in catalogue maintenance; and validation of subject headings during retrospective catalogue conversion

Abstract

Substantial efforts to establish standards for encoding and accessing electronic resources have occured over the past 5 years. Reports the design of a Web based tool, Spectrum, to enable individuals without specialized knowledge of library cataloguing or markup to create records for describing and accessing networked electronic resources of various types. System users may create descriptions of electronic resources and view them as formatted USMARC bibliographic records; TEI headers and URCs. Because continued volatitlity in the definition of data element standards is anticipated, the Spectrum system is designed to allow maximum flexibility in the design of the input formats

Abstract

Emerging standards in knowledge representation and organization are preparing the way for distributed vocabulary support in Internet search services. NetLab researchers are exploring several innovative solutions for searching and browsing in the subject-based Internet gateway, Electronic Engineering Library, Sweden (EELS). The implementation of the EELS service is described, specifically, the generation of the robot-gathered database 'All' engineering and the automated application of the Ei thesaurus and classification scheme. NetLab and OCLC researchers are collaborating to investigate advanced solutions to automated classification in the DESIRE II context. A plan for furthering the development of distributed vocabulary support in Internet search services is offered.
