- Abstract
- For more than thirty years thesauri have been valuable tools in information retrieval. Originally, the basic function of the thesauri was to help the indexer to transform concepts and their relationships, as expressed in the language of documents, into the more regularised indexing language of catalogues and databases. In the nineties another important purpose of the thesauri is to guide the searcher to the best search terms. In spite of the new role, the design of the thesauri has remained more or less stable. This paper explores the demands which are put on the thesauri in relation to searching. Findings are presented in the form of generalisations and moreover illustrated in relation to a real-life situation. Suggestions for improved functionality are presented in the form of a prototype of a thesaurus record. The new role as a conceptual searching tool is also influencing the construction process. Therefore, the paper ends up with a discussion of new methods for thesaurus construction
