					FAST: A Faceted Application
  of Subject Terminology

   Classification Crosswalks Workshop
   Joint Conference on Digital Libraries
               June 28, 2001
          Presented by Ed O’Neill
Background

Enormous volume and rapid growth of
 resources available on the World Wide Web.


Emergence of numerous metadata schemes
 have spurred a re-examination of the way
 subject data is to be provided for web
 resources efficiently and effectively.
 Metadata

Simplicity refers to the usability by non-
 catalogers to allow the creation of metadata
 records by persons not necessarily trained in
 sophisticated methods of bibliographic control.


Semantic interoperability enables users to
 search across discipline boundaries and,
 desirably, also across information retrieval and
 storage systems.
ALCTS/SAC/Subcommittee:
Requirements
 Be simple and easy to apply and to comprehend,

 Be intuitive so that sophisticated training in subject
  indexing and classification, while highly desirable, is
  not required in order to implement,

 Be logical so that it requires the least effort to
  understand and implement,

 Be scalable for implementation from the simplest to
  the most sophisticated.
Options for Metadata


We are limited to three basic choices in selecting
an indexing/subject heading schema for
metadata:

 The use an existing schema(s),
 Adapt or modify an existing schema.
 Develop new schema(s),
Objective of FAST Project

Develop a new subject heading schema
based on LCSH suitable for metadata
which is easier to use, understand, and
maintain.

 Minimized the need to construct
headings,
 Simplify the syntax,
 Retain the richness of the vocabulary.

Advantages of LCSH
 Rich vocabulary covering all subject areas,
 It has the strong institutional support of the Library of
  Congress,
 Synonym and homograph control,
 Has been extensively used by libraries, contained in
  millions of bibliographic records,
 Has a long and well-documented history.

Patterns Subdivisions

 Pattern subdivisions, like free-floats, are subdivisions
 which have general application. However, the scope
 of patterns is limited to particular types (patterns) of
 headings.


 Patients is one of several hundred subdivisions that
 can be used with headings for individual or types of
 diseases and other medical conditions …

 Burns and scalds x Patients
Combining Pattern Subdivisions

Burns and scalds x Patients
   x Family relationships

Burns and scalds is an established heading,
Burns and scalds is covered by the disease pattern,
Patients is authorized under the pattern for diseases
Burns and scalds x Patients
  becomes a class of persons,

Family relationships
  is authorized under the pattern for classes of persons.

 Separating syntax from semantics, the
  syntax can be simplified while retaining the
  richness of vocabulary in LCSH is retained,


 FAST and LCSH can co-exist.
