Abstract
A self-organizing personal file system is disclosed that evaluates the 'importance' of terms and phrases in a document in a personal corpus relative to usage in a reference corpus. A personalized term weighting scheme assigns a weight to terms or phrases based on the frequency of occurrence of the corresponding term or phrase in a reference corpus. Documents are positioned in a visual file space associated with a personal corpus by storing each of the documents with an indication of the term weight for terms appearing in the corresponding document. A singular value decomposition is performed based on the term weights to position a given document in the visual file space based on a relative frequency distribution of terms of the document compared to the occurrence of such terms in a reference corpus.
