21、The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-g

22、overnmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2

23、. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a

24、vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 25964-1 was prepared by Technical Committee ISO/TC 46, Information and documentation, Subco

25、mmittee SC 9, Identification and description. This first edition of ISO 25964-1 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 re

26、maining clauses cover new material. ISO 25964 consists of the following parts, under the general title Information and documentation Thesauri and interoperability with other vocabularies: Part 1: Thesauri for information retrieval The following parts are under preparation: Part 2: Interoperability w

27、ith other vocabularies This part of ISO 25964 covers the development and maintenance of thesauri, both monolingual and multilingual, including formats and protocols for data exchange. ISO 25964-2 will cover interoperability between different thesauri and with other types of structured vocabulary, su

28、ch as classification schemes, name authority lists, ontologies, etc., not previously covered in any International Standard. BS ISO 25964-1:2011ISO 25964-1:2011(E) vi ISO 2011 All rights reservedIntroduction Todays thesauri are mostly electronic tools, having moved on from the paper-based era when th

29、esaurus standards were first developed. They are built and maintained with the support of software and need to integrate with other software, such as search engines and content management systems. (For example, data from the thesaurus database might need to be presented in combination with the numbe

30、r of postings found by a search application.) Whereas in the past thesauri were designed for information professionals trained in indexing and searching, today there is a demand for vocabularies that untrained users will find to be intuitive, and for vocabularies that enable inferencing by machines.

31、 ISO 25964 makes the transition that is needed in order to be compatible with the world of electronic information management. However, this part of ISO 25964 retains the assumption that human intellect is usually involved in the selection of indexing terms and in the selection of search terms. If bo

32、th 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 o

33、f data is a vital component of thesaurus management and exploitation. This part of ISO 25964 therefore includes recommendations for exchange formats and protocols. Adoption of these will facilitate interoperability between thesaurus management systems and other computer applications, such as indexin

34、g and retrieval systems, that will utilize the data. This part of ISO 25964 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, cons

35、istent 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 catego

36、rization schemes, free-text search systems, etc. ISO 25964-2 will address additional types of structured vocabulary (such as classification schemes, name authority lists, ontologies, etc.) and give recommendations to enable interoperation of the vocabularies at all stages of the information storage

37、and retrieval process. BS ISO 25964-1:2011INTERNATIONAL STANDARD ISO 25964-1:2011(E) ISO 2011 All rights reserved 1Information and documentation Thesauri and interoperability with other vocabularies Part 1: Thesauri for information retrieval 1 Scope This part of ISO 25964 gives recommendations for t

38、he 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) inc

39、luding knowledge bases and portals, bibliographic databases, text, museum or multimedia collections, and the items within them. This part of ISO 25964 also provides a data model and recommended format for the import and export of thesaurus data. This part of ISO 25964 is applicable to monolingual an

40、d multilingual thesauri. This part of ISO 25964 is not applicable to the preparation of back-of-the-book indexes, although many of its recommendations could be useful for that purpose. This part of ISO 25964 is not applicable to the databases or software used directly in search or indexing applicati

41、ons, but does anticipate the needs of such applications among its recommendations for thesaurus management. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 array group of sibling concepts (2.52) EXAMPLE In the following, the sibling concepts

42、outerwear and underwear form an array within the concept “clothing”. clothing outerwear overcoats underwear 2.2 associative relationship relationship between a pair of concepts (2.11) that are not related hierarchically but share a strong semantic connection BS ISO 25964-1:2011ISO 25964-1:2011(E) 2

43、ISO 2011 All rights reserved2.3 broader term preferred term (2.45) representing a concept (2.11) that is broader than the one in question NOTE The scope of the narrower concept falls completely within the scope of the broader. The relationship between the two is commonly indicated with the tag BT. F

44、or more explanation see 10.2.1. 2.4 characteristic of division attribute by which a concept (2.11) can be subdivided into an array (2.1) of narrower concepts (2.11), each having a distinct value of that attribute cf. facet analysis (2.21), node label (2.38) EXAMPLE In the following, age group is the

45、 characteristic of division applied to the concept of people: people (people by age group) children youths adults 2.5 classification classifying activity involving the components of grouping similar or related things together; separating dissimilar or unrelated things; and arranging the resulting gr

46、oups in a logical and helpful sequence 2.6 classification scheme schedule (2.49) of concepts (2.11) and pre-coordinated combinations of concepts (2.11), arranged by classification (2.5) NOTE A classification scheme often also includes an index. 2.7 coined term new term (2.61) created to express a co

47、ncept (2.11) for which no suitable term (2.61) exists in the required language NOTE For a further explanation and examples, see 6.6.5 and 9.3.3.3 2.8 compound equivalence relationship or mapping in which one term (2.61) or concept (2.11) in one context is represented by two or more terms (2.61) or c
