1. A method for automatically determining a semantic structure of an electronically formatted natural language based document consisting essentially of words, the method comprising the steps of:
- a) providing a numerical representation as a digital signal of the words within the document wherein said numerical representation contains some information relating the semantic content of the word to the semantic content of the documentb) performing a wavelet transform on said signal, thereby determining the semantic structure.

Abstract
A method for automatically partitioning an unstructured electronically formatted natural language document into its sub-topic structure. Specifically, the document is converted to an electronic signal and a wavelet transform is then performed on the signal. The resultant signal may then be used to graphically display and interact with the sub-topic structure of the document.
