BS 8723-1 This part of BS 8723 sets out the definitions, symbols and abbreviations and other conventions forinformation retrieval applications of structured vocabularies.
The BS 8723 series gives recommendations for the development and maintenance of structured vocabularies of subject terms and concepts for information retrieval.It also gives guidance on the exchangeof data between multiple vocabularies and between a vocabulary and the software with which it interacts.BS 8723 applies to vocabularies used for retrieving information from text resources, such as knowledgebases, bibliographic databases or collections of full text documents, and also catalogues of images orartefacts, such as those in a museum collection.Structured vocabularies are used in post-coordinateretrieval systems, hierarchical directories, pre-coordinate indexes and classification systems.
BS 8723 does not apply to the preparation of back-of-the-book indexes, although many of its
recommendations may be useful for that purpose. It does not cover the structure of authority files of propernames of people, organizations and places, while recognizing that these may sometimes interact withvocabularies of subject terms.
For the purposes of this British Standard, the following definitions apply.Where a term used in a definitionis also defined in this clause, the term is italicized.
