CLS Framework: ISO 12620 data categories section 09

Description: A formalized language used to characterize data or the content of documents to permit their storage and retrieval. 9.1 thesaurus name - see A.9.2 9.2 thesaurus descriptor 9.2.1 top term 9.2.2 broader term 9.2.3 narrower term 9.2.4 related term 9.3 nondescriptor - disallowed (reason A) - (use <note>) 9.4 keyword 9.5 index heading 9.1 thesaurus name - see A.9.2 Admitted name: thesaurus Description: The title of a thesaurus from which a descriptor is taken. Note: Terminologically speaking thesaurus and thesaurus name are not synonyms, but as data category names, they function as if they were synonyms since the content of both categories will indeed be the name of a thesaurus. 9.2 thesaurus descriptor Admitted name: descriptor Description: The term in a thesaurus that can be used to represent a concept in a document or in a request for retrieval. Note 1: For definition of related term, see ISO 5127-6:1983, 3.4.2-02 Blind MARTIF Representation for A.9.2: <ref type=thesaurusDescriptor target=YThes>...</ref>, where YThes is the refid of a <refObject type=thesaurusName> and where content is a unique thesaurus desciptor. The second format is for when there is no formal thesaurus (note similarity to format for Section 7): Blind MARTIF Represenation for A.9.*: <ref type=X target=Z>...</ref>, where X is the name of the thesaurus relation to the other concept and Y is the refid of another termEntry and the content is a name for the implicit thesaurus system. The values of X are from this section (Section 9): 9.2.1 top term 9.2.2 broader term 9.2.3 narrower term 9.2.4 related term Note 2: Although concept systems and thesauri can both be used to represent information and knowledge, concept systems are used to represent concept structures in terminology and information management, whereas thesauri are constructed specifically for information retrieval purposes in library science and documentation environments. The two traditions are subject to different conventions and rules and would not normally be combined. Nevertheless, a terminological entry can indicate that a term is a thesaurus descriptor in a documentary language. A number used to represent concept position or the position of a thesaurus descriptor is frequently called a notation. 9.2.1 top term Description: A thesaurus descriptor representing the highest level concept in a hierarchical relation. Blind MARTIF Representation: <ref type=topTerm target=Z>...</ref> 9.2.2 broader term Description: A thesaurus descriptor representing a superordinate term in a hierarchical relation. Note: For definition of related term, see ISO 5127-6:1983, 3.4.6.2-01 Blind MARTIF Representation: <ref type=broaderTerm target=Z>...</ref> 9.2.3 narrower term Description: A thesaurus descriptor representing a subordinate term in a hierarchical relation. Note: For definition of related term, see ISO 5127-6:1983, 3.4.6.2-04 Blind MARTIF Representation: <ref type=narrowerTerm target=Z>...</ref> 9.2.4 related term Description: <thesaurus descriptor> A term connected to another term by a coordinate or associative relation. Blind MARTIF Representation: <ref type=relatedTerm target=Z>...</ref> 9.3 nondescriptor Description: A term in a thesaurus that must not be used to represent a concept, but that refers to one or more descriptors to be used instead. Note: For definition of related term, see ISO 5127-6:1983, 3.4.2-03 Example: With reference to Annex C, Figure C.7, "Noise, engine" would be a nondescriptor. 9.4 keyword Description: A word or group of words, possibly in lexicographically standardized, i.e., lemmatized, form, taken out of a title or of the text of a document characterizing its content and enabling its retrieval. Example: The terms "data category" and "terminological entry" are keywords for this International Standard. Blind MARTIF Representation: <admin type=keyword>...</admin> Note: Allowed only at the ntig level. 9.5 index heading Admitted name: index word Description: A term chosen to be used in an index to represent an item or a concept in a document. Example: All data categories specified in this standard are included as index headings in the index, as are a number of permuted forms, common synonyms, and variants. Note: Keywords are frequently used as index headings, but not all index headings actually occur in documents, as it is good practice to also include those terms as index headings that a potential reader is likely to search for in a document. Blind MARTIF Representation: <admin type=indexHeading>...</admin> Note: Allowed only at the ntig level.
