    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
    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
    Amid the debates about whether folksonomies will supplant controlled vocabularies and whether the Library of Congress Subject Headings (LCSH) and Dewey Decimal Classification (DDC) system have outlived their usefulness, libraries, museums and other organizations continue to require efficient, effective access to controlled vocabularies for creating consistent metadata for their collections . In this article, we present an approach for using Web services to interact with controlled vocabularies. Services are implemented within a service-oriented architecture (SOA) framework. SOA is an approach to distributed computing where services are loosely coupled and discoverable on the network. A set of experimental services for controlled vocabularies is provided through the Microsoft Office (MS) Research task pane (a small window or sidebar that opens up next to Internet Explorer (IE) and other Microsoft Office applications). The research task pane is a built-in feature of IE when MS Office 2003 is loaded. The research pane enables a user to take advantage of a number of research and reference services accessible over the Internet. Web browsers, such as Mozilla Firefox and Opera, also provide sidebars which could be used to deliver similar, loosely-coupled Web services.

    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
    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
    Subject queries were extracted from 3 universities' online catalogues and analysed to determine the extend to which they matched subject headings in the LCSH. Computer analyses show that nearly 25% of the subject queries entered by online catalogue users are exact matches of LCSH. Yet, manual analyses show that, even though a user matches or closely matches LCSH-mr, the citations retrieved by this vocabulary are not necessarily satisfactory. Sometimes the closest LCSH-mr is not at all pertinent to a user's topic of interest. This study presents reasons why close matches of LCSH-mr are not always satisfactory and suggests approaches to finding the best matches of the catalogue's controlled vocabulary

    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
    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
    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
    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
    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
    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

    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
