Abstract

Normalizing a measure of the level of current interest of an item that is based on indications of interest received from one or more users of a network via which the item is accessible is disclosed. In one embodiment, an intensity value is determined for each successive indication of interest received with respect to an item. At the time each successive indication of interest with respect to the item is received, an intensity rank based at least in part on the intensity value of the received indication is calculated. The calculated intensity rank is multiplied by a normalization factor to determine a normalized intensity rank.
