Patent ID: 8326843

Claim:
A computer-implemented method for making a data collection navigable by a user as a function of correlations between a plurality of metadata for each data file in said data collection and categories of said data files, wherein the computer-implemented method is configured to perform one or more functions on said data collection by performing an action on a graphic representation of a corresponding respective part of said data collection including the steps of organizing said database for use by said user by: (a) analysing metadata regarding each of a plurality of data files in a data collection; (b) calculating correlations between said metadata of each of said data files and said categories; (c) for each one of a plurality of said categories, providing a graphical representation of the data files in said data collection grouped by values of said categories; (d) associating an action involving said graphical representation or a part thereof with a selection function such that selecting one or more values of a category on said graphical representation results in said graphical representation corresponding to a tier of said data collection including only said data files having said selected category values, whereby said selection function is repeatable for causing said graphical representation to correspond to another tier of said data collection narrower than a previous tier; said data collection thereafter, being navigable by a user narrowing the number of data files in said graphical representation in accordance with the category values selected by the user.
