Abstract

A system that facilitates computation of a time-dependent variability value is described herein. The system includes a receiver component that receives a plurality of items, wherein each item has a timestamp corresponding thereto. The system further includes a value generator component that outputs a time-dependent variability value for an item in the plurality of items, wherein the time-dependent variability value is indicative of a recent frequency of use of the item in comparison to a frequency of use of the item over a defined period of time.
