Method for retrieving case for problem and inferring solution of the problem and system thereof

摘要

In a method of retrieving optimum case information for a current problem, case candidates having features of the current problem and common features are retrieved from information representing a plurality of cases stored in a case base in response to presentation of the current problem. A storing unit stores the case base, and respective cases include case problems and solutions or solving methods for the case problems. An optimum case candidate among case candidates is determined from a group of features of the current problem, a group of common features and a group of features of problems of respective case candidates in accordance with influence relation information indicating a feature group influenced by other feature groups. Case information corresponding to the optimum case candidate is retrieved from information representing a plurality of cases.
