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: The paper describes a project to add value to controlled vocabularies by making inter-vocabulary associations. A methodology for mapping terms from one vocabulary to another is presented in the form of a case study applying the approach to the Educational Resources Information Center (ERIC) Thesaurus and the Library of Congress Subject Headings (LCSH). Our approach to mapping involves encoding vocabularies according to Machine-Readable Cataloging (MARC) standards, machine matching of vocabulary terms, and categorizing candidate mappings by likelihood of valid mapping. Mapping data is then stored as machine links. Vocabularies with associations to other schemes will be a key component of Web-based terminology services. The paper briefly describes how the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) is used to provide access to a vocabulary with mappings.

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

Form subdivisions have always been an important part of the Library of Congress Subject Headings. However, when the MARC format was developed, no separate subfield code to identify form subdivisions was defined. Form and topical subdivisions were both included within a general subdivision category. In 1995, the USMARC Advisory Group approved a proposal defining subfield v for form subdivisions, and in 1999 the Library of Congress (LC) began identifying form subdivisions with the new code. However, there are millions of older bibliographic records lacking the explicit form subdivision coding. Identifying form subdivisions retrospectively is not a simple task. An algorithmic method was developed to identify form subdivisions coded as general subdivisions. The algorithm was used to identify 2,563 unique form subdivisions or combinations of form subdivisions in OCLC's WorldCat. The algorithm proved to be highly accurate with an error rate estimated to be less than 0.1%. The observed usage of the form subdivisions was highly skewed with the 100 most used form subdivisions or combinations of subdivisions accounting for 90% of the assignments.

Abstract

This paper reports on an investigation to use Faceted Application of Subject Terminology (FAST) as a surrogate for tags in WorldCat, a global catalog of bibliographic records and location information for books, videos, music, and other types of materials found in libraries. FAST is a controlled vocabulary based on the Library of Congress Subject Headings (LCSH). FAST is applied to a copy of WorldCat to explore the potential of generating tag-like information for bibliographic records. The paper provides sample visualizations of FAST headings inspired by social tagging applications. FAST Headings as Tags for WorldCat - ResearchGate.

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

An analysis of a sample of 9.442 headings assigned by the LoC to bibliographic records disclosed 2 types of invalid headings: those that were erroneous and those that were obsolete. Each type revealed recurring patterns. Errors and obsolete elements occuring in assigned heading involve MARC coding, terminology in main headings and subdivisions, application of subdivisions, and in mechanical elements such as punctuation and capitalization. Different headings (e.g. personal name, corporate name, topical, etc.) display different patterns as well as predominance of errors and obsoleteness. Although the overall error rate is low, an awareness and understanding of patterns of errors and obsolescnce in subject heading strings should contribute to improvement in subject heading assignment and subject authority control

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.

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
