A model of cognitive load for information retrieval: implications for user relevance feedback interaction

Preliminary experimentation demonstrates that although a system that allows for context specific spontaneity is likely to improve the acquisition of user relevance feedback, this is by no means a solution. We believe that the problems associated with a lack of willingness to modify queries or to provide relevance feedback within the Web environment, are indicative of a high state of cognitive load. A number of task and cognitive variables exist and need to be identified before a model of cognitive load for IR can be developed
