In this paper, we observed that the same results are often shown to
users multiple times during search sessions. We showed that there are
a number of effects at play, which can be leveraged to improve information
retrieval performance. In particular, previously skipped results are much
less likely to be clicked, and previously clicked results may or may not
be re-clicked depending on other factors of the session.
