Abstract
A hierarchical collection of items including one or more sub collections of items ordered in a hierarchy is received. A statistical measure of frequency of an item in a sub collection of items is determined. Further, statistical measures of weightages of the item are determined defining a number of sub collections in the hierarchical collection of items in which the item appears and a number of sub collections in which the item appears. A statistical measure of variability defining a number of occurrences of the item in the hierarchical collection of items across different sub collections is calculated. Furthermore, a relevance score of the item is determined based on the statistical measure of frequency, the one or more statistical measures of weightages of the item and the statistical measure of variability. Based on the relevance score, the item is presented on a computer generated graphical user interface.
