Abstract

With the current information environment characterized by the proliferation of digital resources, including collaboratively created and shared resources, Library of Congress Subject Headings (LCSH) is facing the challenges of effective and efficient subject-based organization and retrieval of digital resources. To explore the feasibility of utilizing LCSH in a digital environment, we might need to revisit its basic characteristics. The objectives of our study were to analyze LCSH in both syntactic and relational structures, to discover the structural characteristics of LCSH, and to identify problems and issues for the feasibility of LCSH as an effective subject access tool. This study reports and discusses issues raised by the syntactic and hierarchical structures of LCSH that present challenges to its use in a networked environment. Given the results of this study, we recommend a number of provisional future directions for the development of LCSH towards further becoming a viable system for digital and networked resources.

Abstract

Recent trends, driven to a large extent by the rapid proliferation of digital resources, are forcing changes in bibliographic control to make it easier to use, understand, and apply subject data. Subject headings are no exception. The enormous volume and rapid growth of digital libraries and repositories and the emergence of numerous metadata schemes have spurred a reexamination of the way subject data are to be provided for such resources efficiently and effectively. To address this need, OCLC in cooperation with the Library of Congress, has taken a new approach, called FAST (Faceted Application of Subject Terminology). FAST headings are based on the existing vocabulary in Library of Congress Subject Headings (LCSH), but are applied with a simpler syntax than required by Library of Congress application policies. Adapting the LCSH vocabulary in a simplified faceted syntax retains the rich vocabulary of LCSH while making it easier to understand, control, apply, and use.

Abstract

In respect to the nature and quantity of available information, 1876 was a very different world from the one we know in the 1990s. Yet in spite of over a century of changes, the Dewey Decimal Classification (DDC), the system that helped organize a small college library, has grown to one that is helping the whole world organize its vast store of information resources. In this closing session, I would like to summarize some of the major factors that have contributed so far to the Dewey system's success as an information organization tool. I will also discuss ongoing efforts to ensure its viability in the future

Abstract

The rapid growth of Internet resources and digital collections has been accompanied by a proliferation of metadata schemas, each of which has been designed based on the requirements of particular user communities, intended users, types of materials, subject domains, project needs, etc. Problems arise when building large digital libraries or repositories with metadata records that were prepared according to diverse schemas. This article (published in two parts) contains an analysis of the methods that have been used to achieve or improve interoperability among metadata schemas and applications, for the purposes of facilitating conversion and exchange of metadata and enabling cross-domain metadata harvesting and federated searches. From a methodological point of view, implementing interoperability may be considered at different levels of operation: schema level, record level, and repository level. Part I of the article intends to explain possible situations in which metadata schemas may be created or implemented, whether in individual projects or in integrated repositories. It also discusses approaches used at the schema level. Part II of the article will discuss metadata interoperability efforts at the record and repository levels.

Abstract

Purpose - The purpose of this paper is to investigate the linking of a folksonomy (user vocabulary) and LCSH (controlled vocabulary) on the basis of word matching, for the potential use of LCSH in bringing order to folksonomies. Design/methodology/approach - A selected sample of a folksonomy from a popular collaborative tagging system, Delicious, was word-matched with LCSH. LCSH was transformed into a tree structure called an LCSH tree for the matching. A close examination was conducted on the characteristics of folksonomies, the overlap of folksonomies with LCSH, and the distribution of folksonomies over the LCSH tree. Findings - The experimental results showed that the total proportion of tags being matched with LC subject headings constituted approximately two-thirds of all tags involved, with an additional 10 percent of the remaining tags having potential matches. A number of barriers for the linking as well as two areas in need of improving the matching are identified and described. Three important tag distribution patterns over the LCSH tree were identified and supported: skewedness, multifacet, and Zipfian-pattern. Research limitations/implications - The results of the study can be adopted for the development of innovative methods of mapping between folksonomy and LCSH, which directly contributes to effective access and retrieval of tagged web resources and to the integration of multiple information repositories based on the two vocabularies. Practical implications - The linking of controlled vocabularies can be applicable to enhance information retrieval capability within collaborative tagging systems as well as across various tagging system information depositories and bibliographic databases. Originality/value - This is among frontier works that examines the potential of linking a folksonomy, extracted from a collaborative tagging system, to an authority-maintained subject heading system. It provides exploratory data to support further advanced mapping methods for linking the two vocabularies.

Abstract: Suggests that recent developments in the way information is generated, packaged amd accessed have broadened and changed the nature and application of classification in library and information networks. Examines the role of classification by posing the following questions: what, how and why do we classify? Within this context the expanding role of classification is examined with regard to how classification affects accessing, browsing, identifying, navigating, mapping and evaluating information and how it is and may be used in collection and database management, controlled vocabulary construction and development, and research
