A cognitive view of the situational dynamism of user-centered relevance estimation

Research aimed at observing the interaction between users and information systems has traditionally been diminished by the difficulties associated with controlling the situational dynamism of user-centered relevance estimation. This article identifies a methodology for operationalizing this concept from a cognitive view. It proposes a framework which allows the user to articulate the cognitive schema that is used for estimating relevance and a methodology for recording the changes to this schema that occur during the information-retrieval interaction.
