1. A method for multi-document aggregation, said method comprising: constructing a document redundancy graph from a document set, said document redundancy graph comprising a plurality of nodes wherein each node of said plurality of nodes represents a unique cluster of information and wherein said plurality of nodes comprise at least one redundant node comprising duplicate clusters of information extracted from a plurality of documents of said document set; determining a longest acyclic path in said document redundancy graph; displaying each node of said plurality of nodes of said longest acyclic path in a first column of a plurality of columns on a graphical user interface; displaying said each node in a position in said first column corresponding to a position in said longest acyclic path; displaying at least one node of a branching path in said document redundancy graph in an additional column of said plurality of columns in a position corresponding to a position in said document redundancy graph where said at least one node of said branching path branched from said longest acyclic path of said document redundancy graph on said graphical user interface; providing preference criteria for selecting from said redundant node at least one particular cluster of information; rendering on said graphical user interface said preference criteria; selecting at least one particular document from said at least one redundant node in accordance with a user selection of said preference criterion; and selecting said particular cluster of information from said selected at least one particular document for display.

The method of claim 1 , further comprising: displaying on said graphical user interface at said corresponding position said particular cluster of information of said at least one redundant node.
