Abstract:
This paper gives an overview of the INEX 2010 Ad Hoc
Track. The main goals of the Ad Hoc Track were three-fold. The first
goal was to study focused retrieval under resource restricted conditions
such as a small screen mobile device or a document summary on a hitlist.
The leads to variants of the focused retrieval tasks that address
the impact of result length/reading effort, thinking of focused retrieval
as a form of �snippet� retrieval. The second goal was to extend the ad
hoc retrieval test collection on the INEX 2009 Wikipedia Collection with
additional topics and judgments. For this reason the Ad Hoc track topics
and assessments stayed unchanged. The third goal was to examine the
trade-off between effectiveness and efficiency by continuing the Efficiency
Track as a task in the Ad Hoc Track. The INEX 2010 Ad Hoc Track
featured four tasks: the Relevant in Context Task, the Restricted Relevant
in Context Task, the Restrict Focused Task, and the Efficiency Task. We
discuss the setup of the track, and the results for the four tasks.
