Patent Document ID: 7580910
Application ID: 11393883

Base Claim:
1. A computer-based text processing method, comprising: (a) generating, using a processor, an abstract mathematical vector space based on a collection of documents, wherein respective documents in the collection of documents have a representation in the abstract mathematical vector space and respective terms contained in the collection of documents have a representation in the abstract mathematical vector space; and (b) perturbing, using a processor, the abstract mathematical vector space to produce a perturbed abstract mathematical vector space that is stored in an electronic format accessible to a user, wherein perturbing the abstract mathematical vector space comprises at least one of (i) modifying the representation of a document with a newly computed representation for that document, and (ii) modifying the representation of a term with a newly computed representation for that term.

Claim 7:
7. The computer-based method of claim 1 , wherein perturbing the abstract mathematical vector space further comprises deleting from the perturbed abstract mathematical vector space document data relating to a document.
