Task Effects on Interactive Search: The Query Factor

The purpose of this research is to examine how search differs according to selected task variables. Three types of task information goals and two types of task structures were explored. This mixed within- and between-subjects designed study had 96 participants complete three of 12 tasks in a laboratory setting using a specialized search system based on Lucene. Using a combination metrics (user perception collected by questionnaires, transaction log data, and characteristics of relevant documents), we assessed the effect of goals and structure on search as demonstrated through queries and their use in interactive searching.
