A COMPARISON OF RETRIEVAL STRATEGIES BETWEEN HIGH PERFORMERS AND LOW PERFORMERS OF AN EXPERIMENTAL IR SYSTEM

by Bailey Jr., Earl W

While it is true that many factors can influence information seeking success, the amount of effort exerted by the user in completing a task can be a key factor. This study examined the log files of high performing and low performing users of an experimental system to examine differences in their behaviors performing retrieval tasks. The study examined aspects of elaboration, redundancy, depth, and effort to determine which might be used to predict user success in a retrieval task. Results did not show significant differences between the groups according to elaboration, redundancy, and depth, but did reveal significant differences when comparing the following effort measures: number of documents opened, number of piles used, and number of documents placed into piles. Results indicate that the amount of effort is a good indicator of success in information seeking tasks.
