- Abstract
- 1 characteristic that may affect the way users interest with information systems is the way they organise their knowledge of the topic to be searched. An experiment was conducted to determine the extent and nature of this effect. Subjects who were given different advance organisers read texts and responded to questions about the topics in the texts. These questions were presented in an information retrieval context, on simulated pre-search forms. It was found that different organising structures affected responses to questions in 1 topic of the 3 that were investigated. This demonstrates a complex interaction between the topic of the search, the organising structure employed by users, and questions asked by intermediaries. Because the way users organise their knowledge has an impact on their interaction with information systems, these organising structures may be candidates for inclusion in cognitive models of users
