Are IR Evaluation Measures on an Interval Scale?
ICTIR, pp. 67-74, 2017.
In this paper, we formally investigate whether, or not, IR evaluation measures are on an interval scale, which is needed to safely compute the basic statistics, such as mean and variance, we daily use to compare IR systems. We face this issue in the framework of the representational theory of measurement and we rely on the notion of diffe...More
