1. A method for evaluating the text content of a document database with respect to a document population, comprising the steps of: (a) providing a computer system having a user interface with a display; (b) gathering documents from said database into said system; (c) normalizing said gathered documents; (d) fingerprinting said gathered documents; (e) determining a text criteria with respect to said document population; (f) forming a net comprising at least two nodes associated by at least one interaction and displayable at said display as two or more spaced apart nodes connected by an interaction; (g) loading said text criteria into at least one of said nodes; (h) for each document of said database, calculating its geometric relative distance from a said node to derive one or more node attractors; (i) displaying said net at said display in combination with one or more document symbols each representing a said document located in correspondence with said calculated relative distance; (j) visually examining the display of said net and document symbols; and (k) determining from said document symbol locations at said display those documents, if any, which are more likely to correspond with said text criteria.
