Abstract

Definition and Scope For the purpose of this reader, subject analysis is understood to encompass vocabulary structuring and subject indexing. Vocabulary structuring refers to the constructing of tools, such as classifications, subject heading lists, and thesauri, designed to facilitate the organization and retrieval of information. These tools, though called by different names, are similar in that they structure or control the basic vocabulary of a subject index language by 1) stipulating terms that may be used in the classing or indexing of documents and 2) displaying semantic relationships, such as hierarchy and synonymy, that obtain between these terms. They differ in the kinds of terms and relationships they recognize and in the manner in which these are displayed. Subject indexing refers to the application of a vocabulary, which may be more or less well structured, to indicate the content or aboutness of documents. Traditionally subject indexing limits its domain to only certain types of documents, such as passages within books (back-of-book indexing) or periodical articles, and the expression it uses to only certain types of strings, for example, descriptors or index terms as opposed to subject headings or class numbers. However, in a generalized and more modern sense, subject indexing refers to the indication of the theme or topic of any document, indeed any retrieval artifact, by any meaningful string of alphanumeric characters. The value of construing the meaning of subject analysis broadly is threefold: it permits comparing a variety of approaches to subject analysis; it permits generalizing about these approaches at a relatively high descriptive level, so that principles and objectives are shown in relief; and, most importantly perhaps, it permits a unified view of the traditional and information scientific approaches to subject analysis.
