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

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.
