Patent ID: 7921121

Claim:
A data structure stored on a computer-readable storage media in a computer processing system, the data structure including: an entry for each object in a collection of objects, each entry storing an interest priority value for each associated object in the collection responsive to at least one attribute of the associated object, wherein each interest priority value indicates a relative importance of the corresponding object to an accessing individual compared to other objects in the collection, wherein the interest priority value of a given object in the collection to the accessing individual is calculated by the computer processing system based on similarity of the given object to other objects in the collection previously accessed by the accessing individual, such that the interest priority value of the given object is automatically decreased as the similarity of the given object to other objects in the collection previously read by the accessing individual increases, the number of other individuals in a group to which the accessing individual belongs that have accessed the given object, such that the interest priority value of the given object is automatically decreased as the number of other individuals in the group that have accessed the given object increases, wherein membership in the group to which the accessing individual belongs is automatically determined from a group membership database, and the number of individuals in a group to which the accessing individual does not belong that have accessed the given object, such that the interest priority value of the given object is automatically increased as the number of individuals in the group to which the accessing individual does not belong that have read the given object increases, wherein membership in the group to which the accessing individual does not belong is automatically determined from the group membership database.
