Overview
ISO 5963:1985, titled "Documentation - Methods for examining documents, determining their subjects, and selecting indexing terms," is an international standard established by ISO to provide guidance on document analysis and subject indexing. It outlines general techniques applicable to all indexing situations where human indexers analyze the content of documents and represent their subjects with controlled indexing terms. The purpose of this standard is to promote consistent indexing practices within individual agencies, among networks of agencies, and particularly between different indexing bodies that exchange bibliographic records.
This standard focuses on the preliminary stages of indexing, including document examination, concept identification, and the careful selection of indexing terms. It is designed primarily for human indexers, distinct from automatic or computerized indexing methods.
Key Topics
-
Document Examination
Thoroughly analyzing documents by studying titles, abstracts, contents, illustrations, and text to understand subject matter. Both print and non-print media (including audiovisual material and realia) are covered, with guidance on how to approach indexing for varying document types.
-
Concept Identification
Systematically determining the key concepts or themes essential to a document’s subject. The standard recommends establishing checklists tailored to specific subject fields to guide indexers in identifying relevant concepts.
-
Exhaustivity and Specificity
- Exhaustivity involves the number of concepts covered in the indexing terms, aiming for comprehensive subject representation.
- Specificity addresses how precisely a concept is represented by indexing terms in the controlled language, balancing detail with practical retrieval consideration.
-
Selecting Indexing Terms
Translating identified concepts into appropriate terms, preferably nouns or noun phrases derived from natural language or classification symbols. The standard advises the consistent use of preferred terms and recommends consulting authoritative reference tools like thesauri, dictionaries, encyclopedias, and classification schemes.
-
Using Thesauri and Controlled Vocabularies
The importance of thesauri conforming to ISO standards (e.g., ISO 2788, ISO 5964) is emphasized for selecting terms consistently and managing relationships like synonyms. The standard recommends using the most specific term available and understanding any special rules in indexing systems that may involve roles, weights, or links.
-
Quality Control and Consistency
Striving for consistency and impartiality in indexing across individuals and teams to enhance predictability and system performance. The standard highlights challenges in decentralized indexing environments and encourages feedback and adjustments to indexing tools and procedures without compromising the integrity of the indexing language.
Applications
-
Library and Information Centers
Libraries and archives benefit from standardized document analysis techniques to index books, journals, reports, and multimedia resources effectively, improving users’ ability to find relevant information.
-
Information Retrieval Systems
The standard guides the preparation of indexing data used by information retrieval systems, including bibliographic databases and automated search engines, by ensuring accurate and consistent subject representation.
-
Multilingual and Networked Indexing Agencies
Organizations involved in sharing bibliographic records can adopt ISO 5963 to harmonize indexing principles, enabling seamless data exchange and interoperability in international and multilingual settings.
-
Abstracting Services and Knowledge Management
Abstracters and information professionals can apply the document examination and concept identification principles to prepare comprehensive abstracts and subject indices that support effective knowledge organization.
