Begreb: kontrolleret ordliste
"There are a number of factors that may contribute to the determination of the optimal combination of the use of natural and controlled language in a search strategy. These include:
| (1) the searching environment, including: subject area; database scope and coverage; online, OPAC or CD-ROM system, and interface design; |
| (2) the searcher, including subject knowledge and searching expertise; |
| (3) retrieval facilities and strategies available; |
| (4) the nature of the search, including: precision requirements; recall requirements; nature of search statement (e.g. one or several words), and type of search (e.g. subject, date, author)." (Rowley 1994, 117) |
Eksempler på typer af kontrollerede vokabularer er kontrollerede emneordslister, autoritetsfiler og tesauruser. Principielt udgør et klassifikationssystem også et kontrolleret vokabular.
I danMARC2 skelnes ikke alene mellem kontrollerede og kontrollerede emneord. Det kan også markeres i hvilken sammenhæng et emneord er kontrolleret.

DOI:10.5860/crl.66.3.212. ABSTRACT: Using controlled vocabulary in the creation and searching of library catalogs has evoked a great deal of debate because it is expensive to provide. Leading to this study were suggestions that because most users seem to search by keyword, subject headings could be removed from catalog records to save space and cost. This study asked, what proportion of records retrieved by a keyword search has a keyword only in a subject heading field and thus would not be retrieved if there were no subject headings? It was found that more than one-third of records retrieved by successful keyword searches would be lost if subject headings were not present, and many individual cases exist in which 80, 90, and even 100 percent of the retrieved records would not be retrieved in the absence of subject headings. |
