17、pment of multilingual thesauri 0 Introduction A trend towards the international exchange of information, fully supported by the UNISIST* Programme of UNESCO, and exemplified by Systems like the International information System for the agricultural sciences and technology (AGRIS) and the Inter- natio

18、nal Nuclear Information System (INIS), clearly calls for a higher commitment to multilingual cooperation. Information Systems are expanding across language boundaries, leading to a notable increase in the Provision sf indexing and retrieval tools which are either language-independent (the Broad Syst

19、em of Ordering), or multilingual. Aids of this kind are essential if retrieval of documents indexed in more than one language is not to depend on the acquisition and use of a Single, dominant language. Indexers or searchers should, where possible, be able to work in their mother tongues, or at least

20、 in a language with which they are already familiar. Within this context it is considered that multilingual thesauri have a significant part to play in improving the bibliographic control 0% literature on a global scale. The standardization of procedures for the construction of a multilingual thesau

21、rus is seen as a primary step in achieving compatibility between thesauri produced by indexing agencies using terms selected from different natura1 languages. The recording of these pro- cedures will also enable indexers engaged in this task to benefit from the experience sf others, and to work in a

22、 logical and consistent fashion, using recommended practices which have been established in the course of discussions at an international level. 1 Scope and field of application 1 .l The guidelines given in this International Standard should be used in conjunction with ISO 2788, and regarded as an e

23、xtension of the scope of the monolingual guidelines. lt is considered that the majority of procedures and recommendations contained in ISO 2788 are equally valid for a multilingual thesaurus. This applies particularly to general procedures concerning, for example, the forms of terms, the basic thesa

24、ural relationships, and management operations such as evaluation and maintenance. Except when it appears to be necessary, the procedures described in ISO 2788 are not repeated here, and it is therefore essential to refer to both of these International Standards when constructing a multilingual thesa

25、urus. 1.2 These guidelines are restricted in scope to the Problems of multilingualism which tan arise during the construction of a “con- ventional” thesaurus, i.e. a thesaurus displaying terms selected from more than one natura1 language, these terms then constituting the vocabulary of a controlled

26、indexing language. Throughout this International Standard, a distinction is made between preferred terms and non-preferred terms (sec definitions in clause 3). These guidelines are not applicable to indexing languages in which con- cepts are expressed entirely as Symbols (for example mathematical eq

27、uations or Chemical formulae), nor to Systems which are based on the automatic analysis and searching of free text. lt is considered, however, that a weil-constructed multilingual thesaurus tan play a significant part in improving retrieval from a free-text System which covers documents in more than

As far as possible, however, examples were Chosen which illustrate general Problems and procedures, i.e. those which should apply in any field of knowledge. b) lt is realized that the procedures de

30、scribed in these guidelines may not be entirely appropriate for all languages. The examples have been selected, for entirely pragmatic reasons, from three of the major languages, i.e. English, French and German, but this does not imply that these languages are regarded as dominant in the field of do

37、sis” and the German component “analyse” both represent foci, and the modifying differentes are represented by “Systems” (English) and “System” (German). Despite these surface structural differentes, however, the terms “Systems analysis” and “Systemanalyse” are both regarded as compound terms for the

38、 purposes of this International Standard. 3.3 dominant language: An exchange language (sec 3.5) which is also used for indexing and retrieval in Systems which, for policy reasons, do not give equal Status to all the languages in the System. Every concept recognized in the System must necessarily be

39、represented by a preferred term in the dominant language. In some cases, however, an equivalent expression may be lacking in one more sf the other languages. These other languages are then known as secondary languages. 34 by an equal Status: Languages equivalent preferred term in a multilingual thes

41、e. The exchange language may also be used for indexing and/or retrieval, and the multilingual thesaurus then functions principally as a means Bor translating the local languages sf indexers and enquirers into, or out sf, the exchange language. The different languages in such a System would still be

42、recognized as having equal Status (sec 3.4) if equivalents are established reciprocally between the preferred terms in the exchange language and the pre- ferred terms in all other languages. 36 useful feedback: The act sf changing the form or stru cture sf solution to a Problem encountered in a targ

Direct translation of this term into English or French would call for a complicated Paraphrase,

44、Law of education sf teachers”, or “Loi sur Ia formation des enseignants”. Neither sf these phrases would be regarded as a satisfactory indexing term. A shorter expression, which is closer to the German construction, tan be achieved in English, i.e. “Teacher education law”, but this cannot be done i

46、assigned to documents dealing with this subject. Translation into English and French could then be carried out on this new and simpler basis, i.e. Gesetz = Law = Loi Lehrer = Teachers = Enseignant Bildung = Education = Formation The German compound term “Lehrerbildungsgesertz” may still be retained

Syntactical relationships tan be indicated in various ways in a pre-coordinated index, for example by printing terms in entries in an Order which suggests their relative roles, and so allows the user to perceive the subject as a whole. Despite these differentes, however, both kinds of System tan be based on controlled vocabularies of terms displayed and organized in a thesaurus. 3.8 indexing term: The representation of a concept, preferabiy in the form of a noun or noun Phrase.
