Dear colleagues,

We are pleased to announce the launch of the Switching Detection 
Challenge, which is a part of the WSDM 2013 Web Search Click Data (WSCD) 
workshop. It provides a unique opportunity to consolidate and scrutinize 
the work from industrial labs on predicting the search engine switching 
events using user logged search behavior context. It provides a fully 
anonymized dataset shared by Yandex which has anonymized users ids, 
queries, clicks and search engine switching actions. Detecting the fact 
of switching, when switching events cannot be monitored directly, is 
difficult, and is not yet a solved problem. It is important for 
understanding of users' satisfaction with the search engine and the 
complexity of search tasks. This Challenge and the shared dataset aims 
to enable a whole new set of researchers to study the problem of search 
engine switching detection.

Contestants can participate as individuals, or as teams. You will find a 
detailed description of the task, data sets and result evaluation 
methodology at:
