- 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
- 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 presents the results of an exploratory study to determine literary warrant for topics in electronic resources. The classification numbers in Abridged Edition 14 were used as a starting point. Using the principles of abridgment and expansion in Dewey, a version of the DDC is defined that accommodates the topics found an three diverse Web sites that use Dewey: BUBL, Canadian Information By Subject, and KidsClick! The resulting classes are used to create a database for automated classification of Web resources.

- 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.

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
- 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
- Two measures are examined that characterize the dispersion of a classification system when mapped to a second classification. One, a distance measure, captures the physical spread of a class when represented in the secon system; the second, from rank-frequency-analysis, characterizes the scatter of tokens over a set of types. The measures are tested by applying them to the library science portions of the LCC and the DDC using a database drawn from MARC records. Class mappings are presented that exemplify four extreme points of the two measures considered together: mappings where both measures score high, mappings where both score low, and mappings where one measure is high and the other is low. The conclusion is that the measures characterize two different properties of dispersion

- 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
- To determine the potential benefits of providing classified displays of search results, we analyzed the classification features of the OCLC NetFirst database using criteria developed by the Subject Analysis Committee (SAC) subcommittee an Metadata and Classification. We also studied NetFirst search logs to better understand how the classification-based searching and limiting functions implemented in the system are being used. Our findings suggest that to increase the use of classification-based features in systems for general users, classificatory functions must be well integrated with the basic search and display functions.

- 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.

- Abstract
- The DeweyBrowser allows users to search and browse collections of library resources organized by the Dewey Decimal Classification (DDC) system. The visual interface provides access to several million records from the OCLC WorldCat database and to a collection of records derived from the abridged edition of DDC. The prototype was developed out of a desire to make the most of Dewey numbers assigned to library materials and to explore new ways of providing access to the DDC.
