WSDM Yandex Switching Detection Challenge

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: switchdetect.yandex.ru/en
