Abstract
A method for ranking a plurality of documents relevant to a user profile comprises determining a high resolution representation for the user profile, computing a high resolution representation for each document, calculating a rank for each document based on the high resolution representation of the document and the high resolution representation of the user profile, recalculating the rank for each document based on a lower resolution representation of the document and/or a lower resolution representation of the user profile when the rank of each document is not satisfactory, and outputting a number of the plurality of documents sorted by the rank of each document, when the rank is satisfactory. The high resolution representation can be a discrete wavelet transform. The lower resolution representation can be recalculated by averaging the values of the discrete wavelet transform. Outputting the number of documents can comprise displaying the documents on a device.
