In: ournal of the American Society for Information Science. 50(1999) no.8, S.698-708.
Abstract: In order to determine whether medical students can recognize when an information need has been fulfilled and when it has not, this study examined the quality of medical students' confidence estimate in answering short-answer questions dealing with bacteriology, based upon their personal knowledge alone and what they were able to retrieve from a factual database in microbiology

In: Exploring the contexts of information behaviour: Proceedings of the 2nd International Conference on Research in Information Needs, Seeking and Use in Different Contexts, 13-15 August 1998, Sheffield, UK. Ed. by D.K. Wilson u. D.K. Allen. London : Taylor Graham Publ., 1999. S.290-303.
Abstract: Almost 30 years ago, Taylor (1968) postulated that each information need moves along a continuum from the visceral need through the compromised need. The current study examines the final transition in this continuum: from formalized need (expressed in an explicit verbal statement) to compromised need (represented in the language of the retrieval system). This transition is primarily concerned with vocabulary: the searcher attempts to translate an explicit statement of need into a search term (or terms) that can be interpreted by the retrieval system. A few studies have empirically examined the match between the end-user searcher's formalized need and the compromised need (i.e., search terms). Markey (1984) compared the searcher's expressed topic (the formalized need, expressed in just a few words) and the search terms (the compromised need), and then went on to compare the search terms with the library catalog terms available for subject searching. She found that the search term matched or was a partial form of the expressed topic in 71% of the searches, and that over 75% of these searches matched a catalog term. Allen (1991) examined the relationship between logical reasoning ability and selection of search terms. He asked college students to read a magazine article (which could be seen as a very rich statement of the formalized need) and then to perform a search for articles on the same topic (expressing the compromised need).

In: ASIS'91: systems understanding people. Proc. of the 54th Annual Meeting of the ASIS, vol.28, Washington, DC, 27.-31.10.1991. Ed.: J.-M. Griffiths. Medford : Learned Information Inc., 1991. S.302-312.
Abstract: Search statements in this revision process can be viewed as a 'move' in the overall search strategy. Very little is known about how end users develop and revise their search strategies. A study was conducted to analyse the moves made in 244 data base searches conducted by 26 medical students at the University of North Carolina at Chapel Hill. Students search INQUIRER, a data base of facts and concepts in microbiology. The searches were conducted during a 3-week period in spring 1990 and were recorded by the INQUIRER system. Each search statement was categorised, using Fidel's online searching moves (S. Online review 9(1985) S.61-74) and Bates' search tactics (s. JASIS 30(1979) S.205-214). Further analyses indicated that the most common moves were Browse/Specity, Select Exhaust, Intersect, and Vary, and that selection of moves varied by student and by problem. Analysis of search tactics (combinations of moves) identified 5 common search approaches. The results of this study have implcations for future research on search behaviours, for thedesign of system interfaces and data base structures, and for the training of end users
