ABSTRACT:
A text processing method is provided that includes the following steps. First, an abstract mathematical vector space is generated based on a collection of documents. 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. Then, the abstract mathematical vector space is perturbed to produce a perturbed abstract mathematical vector space that is stored in an electronic format accessible to a user. Perturbing the abstract mathematical vector space may include modifying the representation of a document with a newly computed representation for that document, or modifying the representation of a term with a newly computed representation for that term.
