System amd method of analyzing text using dynamic centering resonance analysis
First Claim
1. A method of analyzing temporal changes in text, comprising:
- extracting first and second portions of the text;
linking words of the first portion of the text;
linking words of the second portion of the text;
forming a first layer of a network from the linked words of the first portion of the text;
forming a second layer of the network from the linked words of the second portion of the text, wherein the second layer exists in a different temporal plane from the first layer; and
linking words common between first and second layers to provide a representation of relationship between the first and second portions of the text.

Abstract
A document analysis tool provides a 3-dimensional network representation of temporal evolution of text in a document. First and second portions of text are extracted from one or more documents. The texts are parsed to identify noun phrases. The noun phrases are stemmed to remove word variations. Words from the first portion of the text are linked together to form a first layer in the network. Words from the second portion of the text are linked together to form a second layer in the network. The second layer exists in a different temporal plane from the first layer. Words that are common between first and second layers are linked together between the first and second layers to provide a visual and analytical representation of relationship between the first and second portions of the text.
