Information retrieval systems can be evaluated in laboratory settings through the use of user studies, and through the use of test collections and effectiveness metrics. In a larger investigation we are exploring the extent to which individual user differences and behaviours can affect the scores generated by a retrieval system. Our objective in the first phase of that project is to define information need statements corresponding to a range of TREC search tasks, and to categorise those statements in terms of task complexity. The goal is to reach a position from which we can determine whether user actions while searching are influenced by the way the information need is expressed, and by the..
