New Measures for the Evaluation of Interactive Information Retrieval Systems: Normalized Task Completion Time and Normalized User Effectiveness

Abstract

User satisfaction, though difficult to measure, is the main goal of Information Retrieval (IR) systems. In recent years, as Interactive Information Retrieval (IIR) systems have become increasingly popular, user effectiveness also has become critical in evaluating IIR systems. However, existing measures in IR evaluation are not particularly suitable for… (More)
