The cognitive aspect of information systems (IS) involves both the certainty and uncertainty aspects of a user need. Certainty refers to what a user knows or what she thinks she knows such as her experience, knowledge, beliefs, goals and plans. Uncertainty refers to what the user is aware of not knowing, and thus needs to find out, which is often called an information need or a cognitive gap. The certainty and the uncertainty constitute the user's perception of her IS situation. Uncertainty is defined in terms of certainty of what she perceives regarding to the situation. Users employ certainty in order to point out what they do not know and thus need to find out, uncertainty. Uncertainty has been focused on as an information need in many studies in the field of information. The certainty aspect, however, has not been explicitly addressed even though it is inherent to human cognition that is the source of IS behavior. Investigates the certainty aspect of a user need in an IS interaction by looking at how users employ what they know when they point out what it is that they want to know. [ABSTRACT FROM AUTHOR] |
