The effect of task type on preferred element types in an XMLâbased retrieval system
This article examines the influence of task type on the users' preferred level of document elements (full articles, sections, or subsections) during interaction with an XML-version of Wikipedia. We found that in general articles and subsections seemed to be the most valuable elements for our test subjects. For information-gathering tasks, this tendency was stronger, whereas for fact-finding tasks, the sections seemed to play a more important role. We assume from this that users select different information search strategies for the two task types. When dealing with fact-finding tasks, users seem more likely to use one single element as an answer, while when they do information gathering, they pick information from several elements
Seven years of INEX interactive retrieval experiments â lessons and challenges
This paper summarizes a major effort in interactive search investigation,
the INEX i-track, a collective effort run over a seven-year period. We present
the experimental conditions, report some of the findings of the participating
groups, and examine the challenges posed by this kind of collective experimental
effort
