    Abstract
    Design and construction of indexing languages require thorough knowledge and understanding of the information environment. This empirical study investigated a mixed set of methods (group interviews, recollection of information needs and word association tests to collect data; content analysis and discourse analysis to analyse data) to evaluate whether these methods collected the data needed for work domain oriented thesaurus design. The findings showed that the study methods together provided the domain knowledge needed to define the role of the thesaurus and design its content and structure. The study was carried out from a person-insituation perspective. The findings reflected the information environment and made it possible to develop a thesaurus according to the characteristics of the work domain. It seemed more difficult to capture the needs of the individual user and adapt the thesaurus to individual characteristics.

    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

    Abstract
    This paper evaluates and compares three thesaurus construction methodologies: literary scanning, word association tests, and involvement of subject expert groups. The evaluation concentrates an exploring advantages in relation to the sub-processes: collection, formation and structuring of concepts and terms. Quantitative as well as qualitative analyses have been carried out. The analysis Shows that the methods are complementary each providing distinct conceptual information from respectively a domain-oriented and a scientific viewpoint. The combination of methods provides a thesaurus, at the same time, mapping authoritative language and reflecting the diversity of language.
