Patent ID: 7356604

Claim:
A method for analyzing documents from a data source, comprising: analyzing a reference corpus using a profile to determine reference corpus document scores indicative of content of documents in the reference corpus relative to the profile; identifying a particular reference corpus document score that corresponds to a particular delivery ratio of documents of the reference corpus based on the analysis of the reference corpus; assigning threshold scores to a multiplicity N of score threshold levels such that the particular reference corpus document score is assigned to be a threshold score for a given one of the N score threshold levels; analyzing a data source using the profile and determining raw document scores for documents from the data source relative to the profile based upon the analysis of the data source; comparing the raw document scores to the threshold scores of the N score threshold levels; assigning normalized document scores to documents of the data source based on the comparison of the raw document scores to the threshold scores of the N score threshold levels as indicators of document relevancy to the profile; and selecting a document based upon its normalized document score.
