Task difficulty in information searching behavior: expected difficulty and experienced difficulty Jeonghyun Kim   View Paper (PDF)   Return to Poster Session Abstract The purpose of the work is to better understand the issue of task difficulty from the perspective of the user. To investigate the relationship between task difficulty and information searching behavior, two types of task difficulty are considered: expected difficulty and experienced difficulty. Information searching behavior was observed via time spent, pages viewed, pages saved, search efficiency and the number of query reformulations.
