Information and documentation — Thesauri and interoperability with other vocabularies — Part 1: Thesauri for information retrieval
ISO 25964-1 was created by Technical Committee ISO/TC 46, Information and documentation, Subcommittee SC 9, Identification and description.
ISO 25964-1, first edition, cancels and replaces ISO 2788:1986 and ISO 5964:1985, which have been merged and technically revised. Clauses 1 to 13 of this part of ISO 25964 correspond broadly to the content of ISO 2788:1986 and ISO 5964:1985. The remaining clauses cover new material.
ISO 25964-1:2011(EN) consists of the following parts, under the general title Information and documentation – Thesauri and interoperability with other vocabularies:
ISO 25964-1:2011(EN) Information and documentation — Thesauri and interoperability with other vocabularies — Part 1: Thesauri for information retrieval
ISO 25964-2:2013(EN) Information and documentation — Thesauri and interoperability with other vocabularies — Part 2: Interoperability with other vocabularies
ISO 25964-1:2011 covers the development and maintenance of thesauri, both monolingual and multilingual, including formats and protocols for data exchange.
ISO 25964-1:2011(EN) makes the transition that is needed in order to be compatible with the world of electronic information management. However, ISO 25964-1:2011 retains the assumption that human intellect is usually involved in the selection of indexing terms and in the selection of search terms. If both the indexer and the searcher are guided to choose the same term for the same concept, then relevant documents will be retrieved. This is the main principle underlying thesaurus design, even though a thesaurus may also be applied in situations where computers make the choices.
Efficient exchange of data is a vital component of thesaurus management and exploitation. ISO 25964-1:2011, therefore includes recommendations for exchange formats and protocols. Adoption of these will facilitate interoperability between thesaurus management systems and other computer applications, such as indexing and retrieval systems, that will utilize the data.
Also,
ISO 25964-1:2011 covers development and maintenance of thesauri rather than how to use them in indexing. Where multilingual issues and examples are addressed, efforts have been made to cover as wide a selection of languages as possible, consistent with clarity and comprehensibility.
Thesauri are typically used in post-coordinate retrieval systems, but may also be applied to hierarchical directories, pre-coordinate indexes and classification systems. Increasingly, thesaurus applications need to mesh with others, such as automatic categorization schemes, free-text search systems
ISO 25964-1:2011 gives recommendations for the development and maintenance of thesauri intended for information retrieval applications. It is applicable to vocabularies used for retrieving information from all types of information resources, irrespective of the media used (text, sound, still or moving image, physical object or multimedia). Including knowledge bases and portals, bibliographic databases, text, museum or multimedia collections, and the items within them.
ISO 25964-1:2011 also provides a data model and recommended format for the import and export of thesaurus data. ISO 25964-1:2011 is applicable to monolingual and multilingual thesauri.
ISO 25964-2:2013(EN) Information and documentation — Thesauri and interoperability with other vocabularies — Part 2: Interoperability with other vocabularies
ISO 25964-2:2013 is applicable to thesauri and other types of vocabulary that are commonly used for information retrieval. It describes, compares and contrasts the elements and features of these vocabularies that are implicated when interoperability is needed. It gives recommendations for the establishment and maintenance of mappings between multiple thesauri. Or between thesauri and other types of vocabularies.
