Abstract

Discusses a new model of search term selection and its implications. The model characterizes the selection of search terms as the navigation of multiple discourses, including controlled vocabularies, documents and their domains, the practice of indexing, clients' speech and search requests, databases and the searcher's own knowledge of the search process. Suggests that the multiple aspects of these discourses influences search term selection. The discourse of a controlled vocabulary is analyzed from various aspects and described as an example of a discourse. Professional searchers and the end users may benefit from adopting this new model of search term selection, learning to see alternative, effective search terms in addition to the words they would normally use. The model can also be incorporated in human computer interfaces of information retrieval systems to support the selection of search terms in a passive or active manner

Abstract

Proposes a model of the search term selection process based on an empirical study of professional searchers during the pre-online stage of the search process. The model chraracterises the selection of search terms as the navigation of different discourses. 6 discourses emerged as sources of search terms: controlled vocabularies, documents and the domain, the practice of indexing, clients' search request, databases and the searchers' own search experience. Searchers navigate the discourses dynamically and have preferences for certain discourses. Emphasises the multiplicity and complexity of sources of search terms, the dynamic nature of the search term selection process and the complex analysis and synthesis of differences and similarities among sources of search terms. Searchers may need to understand fundamental aspects of multiple discourses in order to select search terms
