How query extensions reflect search result abandonments
Aleksandr Chuklin, Pavel Serdyukov · 2012
It is often considered that high abandonment rate corresponds to poor IR system performance. However several studies suggested that there are so called good abandonments, i.e. situations when search engine result page contains enough details to satisfy the user information need without necessity to click on search results. In this work we propose to look at query extensions. We see that an extension by itself might motivate abandonment type (good or bad) for the underlying query to some degree. We also propose a way to find potentially good abandonment extensions in an automated manner.
