Journal of Information Science has published quantitative research by Jesper Kallehauge, a PhD student who graduated rom the Department in 2008. Jesper's supervisor was Professor Nigel Ford.
The title of Jesper's article is 'Stage-driven information seeking process: Value and uncertainty of work tasks from initiation to resolution' (vol. 36, no. 2, 2010, pp. 242–262, DOI: 10.1177/0165551509360142).
"The stage-driven information seeking process to reduce uncertainty and increase value was systematically validated with real users (n=60) with real work tasks from social sciences and applied sciences domains in a UK and Danish university. A broad set of information sources are applied and core relevance criteria are measured. The research seeked to test the hypothesis that the information seeking process is seen as a dynamic and iterative development to reduce uncertainty through four stages until the problem is solved: (1) problem recognition: kind of problem, (2) problem definition: nature of the problem, (3) problem resolution: finding an answer to the problem, (4) solution statement: answer to the problem or how to deal with it. The hypothesis was rejected in this case since there was no significant decrease in uncertainty level from stage 1 to 4."
