Patent ID: 8473314

Claim:
A method for processing data in medical records using a computing apparatus for determining a parameter of a health abnormality precursor, the method comprising: inputting documents into the computing apparatus representing a starting group of medical records having a minimum number of reports over a selected time interval; processing the starting group of medical records to generate respective document vectors; sampling the document vectors by applying a maximum variation sampling function to the document vectors; applying a fitness function to the results of the sampling, including factors to reduce a number of medical records to a reduced group of medical records and to increase the diversity of the medical records for further processing; extracting linguistic phrases from the reduced group of medical records and converting the linguistic phrases to normal health and abnormal health s-grams; applying a Haar wavelet function to the s-grams from medical records in the reduced group of medical records remaining after applying the fitness function; further reducing the number of medical records in the reduced group of medical records for reporting by analyzing coefficient results from applying the Haar wavelet function according to at least one of a plurality of preselected s-gram patterns; and reporting abnormal health s-grams together with a parameter of a health abnormality precursor through a computing output device to a human observer.
