WSCD 2012: workshop on web search click data 2012.

ABSTRACTWSCD2012 is the second workshop on Web Search Click Data, following WSCD2009. It is a forum for new research relating to Web search usage logs and for discussing desirable properties of publicly released search log datasets. Research relating to search logs has been hampered by the limited availability of click datasets. This workshop comes with a new click dataset based on click logs and an accompanying challenge to predict the relevance of documents based on clicks.
