Information-seeking behaviours and cognitive search strategies in different search tasks on the WWW

This study investigates the cognitive strategies of 80 participants as they engaged in two researcher-defined tasks and two participant-defined information-seeking tasks using the WWW. Each researcher-defined task and participant-defined task was further divided into a directed search task and a general-purpose browsing task. On the basis of retrospective verbal protocols, log-file data and observations, 12 cognitive search strategies were identified and explained. The differences in cognitive search strategy choice between researcher-defined and participant-defined tasks and between directed search and general-purpose tasks were examined using correspondence analysis. These cognitive search strategies were compared to earlier investigations of search strategies on the WWW.

Relevance to industry

Describing information-seeking behaviours and cognitive search strategies in detail provides website developers and search engine developers with valuable insights into how users seek (and find) information of value to them. Using this information, website developers might gain some knowledge as to how to best represent the content and navigational properties of websites. Search engine developers might wish to make the search and collection strategies more transparent to users. There are also design implications for the designers of web browsers.
