  • Text mining for large medical text datasets and corresponding medical text classification using informative feature selection
    Patent number: 9075796
    Abstract: Techniques include performing text mining on a set of case reports in text format to determine a set of grammar rules to be used to determine whether case reports meet a medical condition. The text mining includes performing feature selection, used to determine the set of grammar rules, that combines standardized case definitions with experience of medical officers for the medical condition and outputting the set of grammar rules. Another technique includes applying grammar rule(s) to new case report(s), the grammar rule(s) previously determined at least by performing text mining comprised of performing feature selection, used to determine the set of grammar rules, that combines standardized case definitions with experience of medical officers for the medical condition. Indication(s) are output of whether the new case report(s) meet or do not meet the medical condition. The techniques may be performed by a method, an apparatus, and a program product.
