Uncertainty-tolerant design: Evaluating task performance and drag-and-link information gathering for a news-writing task

an article by Simon Attfield, Ann Blandford, John Dowell and Paul Cairns, (UCL Interaction Centre, University College London) in International Journal of Human-Computer Studies Volume 66 Issue 6 (June 2008)

Abstract
Part of the challenge of designing systems to support knowledge work is to do so in a way which is sympathetic to users’ uncertainty. NewsHarvester is a test-bed system designed to support news research and writing in a way that accommodates uncertainty in relation to information gathering. It does this using ‘drag-and-link’; a simple feature by which text extracts copied from source locations are appended with hyperlinks to force the re-display of the source. The authors describe the rationale for using drag-and-link within NewsHarvester based on a previous ethnographic study of journalists, describe its implementation within NewsHarvester, and report a user-evaluation which compared drag-and-link with printing and standard drag-and-drop as information gathering mechanisms. They found that users wanted to relocate information they had not previously identified as useful in order to include it in their report, to better understand the context of information already extracted, and as part of a more serendipitous search for information to add to a near-complete report. Users also considered drag-and-link an easier method for gathering information than printing, and considered that drag-and-link made it easier to relocate information. They also considered that drag-and-link promoted more flexible and dynamic working and increased user enjoyment. An assessment of the quality of their work showed a trend that favoured drag-and-link over the other two methods, although this was not statistically significant. They conclude that drag-and-link improves user-experience during research and writing tasks in the face of information gathering uncertainty.


Hazel's comment:
And it all sounded very interesting until I tried to find this NewsHarvester "thing" as a thing in its own right. I found lots of different news aggregators which have tags and/or keywords of news harvester but not a product that is actually called that.
Ah well, I tried and admit defeat!
Anything which takes more than five minutes to find a sensible answer is not worth looking for (unless, says she with an avaricious gleam in her eye, I'm being paid for my time).
