A process is provided for mapping the relationship of the content of a collection of documents (14). The process includes providing a collection (12) of documents (14) where each document (14) includes text. Relevance measures are determined that represent a relevance between each pair of documents (14) based upon the text of the documents (14). A graph (22) is then generated that has nodes (30) and edges (32) with each edge (32) connecting two nodes (30). The graph (22) has a node (30) associated with each document (14) and has an edge (32) connecting nodes (30) for which the relevance measure between associated documents (14) is greater than a specified threshold. In this manner, the graph (22) maps the relationship of the content of the collection (12) of documents (14).

A system (10) for recursive document retrieval is provided. An original repository (12) comprises a plurality of documents (14), and a query (16) comprises information by which the original repository (12) can be analyzed to identify relevant documents (14). A retrieval engine (18) is coupled to the original repository (12) and receives the query (16). The retrieval engine (18) is operable to execute an automatic recursive retrieval process with respect to the original repository (12) using the query (16) where the automatic recursive retrieval process comprises a plurality of iterations. The retrieval engine (18) is also operable to provide as system output a retrieved repository (28) comprising a plurality of documents (30) from the original repository (12) identified as sufficiently relevant to the query (16) according to the automatic recursive retrieval process for detection as relevant documents.

According to one embodiment of the present invention, a system (10) for arrangement of documents (13) is provided. The system includes a document repository (12) storing a plurality of documents (13). An arrangement engine (14) is coupled to the document repository (12). The arrangement engine (14) is operable to build a plurality of symmetric matrices based upon a plurality of identified arrangements of the plurality of documents (13) in the document repository (12). Each matrix is structured such that each row and each column is associated with a document (13). The arrangement engine (14) is also operable: to fill each cell of each symmetric matrix with a relevance value representing a relevance between a document (13) associated with the row of the cell and a document (13) associated with the column of the cell, to generate a fitness value for each matrix based upon a magnitude and a position of each relevance value by analyzing each symmetric matrix using a fitness function (16), to identify an optimal arrangement of the plurality of documents (13) based upon the fitness value of each matrix, and to provide the optimal arrangement of documents (18) as system output.
