Modeling search and session effectiveness
作者：
Highlights：
• Web search effectiveness can be measured via the utility gained by users.
• Similarly, search session effectiveness can be measured via average utility gain.
• Effectiveness measures also describe models that predict user actions.
• Session measures can be compared by correlating predicted and observed user actions.
• We present a session effectiveness metric that correlates better than previous ones.
