- 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
- 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
- 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
- We describe a new information technology for knowledge organization: the development of a Web-accessible "taxonomy" server based on the top levels of the Dewey Decimal Classification (DDC) system. The server offers a publicly accessible automatic metadata creation tool that returns metadata encoded in XML. This paper discusses the role of the DDC in the project. Included in the metadata is automatic subject assignment based on the DDC and represented in XML. The project also provides a public browsing interface that uses the DDC as its underlying structure the DDC

- Abstract
- This paper describes how the Dewey Decimal Classification (DDC) is being prepared for use as an Internet subject guide. These preparations are being carried out in three phases 1) adding supplemental terminology to the DDC to better lead Internet users to relevant DDC categories, 2) revising the Dewey captions for currency and expressiveness, and 3) prototyping a Web-accessible Dewey Subject Guide that incorporates the outcomes from the earlier phases. Phases 1 and 2 are addressed in detail in this paper

- Abstract
- This study explores ways to assist users who are primarily interested in finding a good story, regardless of format or literary form. The emphasis is on materials classed in the Arts (700s) and Literature (800s) in the Dewey Decimal Classification (DDC) system. Features from two prototypes, FictionFinder and DeweyBrowser, are being combined to attempt to assist users in finding terms to input while providing a holistic approach to finding works with imaginary content.

- 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
- 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
- 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
- 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
