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.

Abstract
Methods and systems for multi-document aggregation provide data representing a redundancy graph constructed from a document or document set and determine the longest acyclic path in the document redundancy graph. Nodes of the longest path are assigned to a column to be displayed. Each node is assigned to a corresponding position in the column according to the node position in the path. Methods and systems for ordering multi documents for presentation can determine the content of a node of the redundancy graph and order the content for display.

12. A method for ordering multi documents for presentation, said method comprising:
-
constructing a document a redundancy graph constructed 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; displaying the text of each node of said plurality of nodes of a first document of said document set in a first column of a plurality of columns on a graphical user interface in a position corresponding to a position in said document redundancy graph and displaying at least one node of a branching path from a second document of said document set in said document redundancy graph in a second column of said graphical user interface in a position corresponding to a position in said document redundancy graph wherein said branching path branched a longest acyclic path; determining the content of said each node and said at least one node of said branching path of said redundancy graph; and ordering said content. - View Dependent Claims (13, 14)

15. A system for multi-document aggregation, said system comprising:
-
a processor; a data bus coupled to said processor; and a computer usable medium embodying computer program code, said computer usable medium being coupled to said data bus; and
said computer program code comprising instructions executable by said processor and configured to;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; determine 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. - View Dependent Claims (16, 17)
