Objective:Todiscuss the application of Decision Tree model and fit classification model of maxillary Ⅲ lymph nodes of breast cancer
which can abstract diagnostic knowledge used for computer-based diagnosis system.Methods:Four classification models of Decision Tree with the arithmetic of C5
CR
QUEST and CHAID were applied for classifying maxillary Ⅲ lymph nodes in 223 cases of breast cancers
confirmed by with 11 diagnostic indexes in the first affiliated hospital of chongqing medical university from 1993 to 2003.Results:CHAID classification model was better than other three models
according to the reliability of diagnostic knowledge and the accuracy of the test samples
the accuracy being 83.79%.Conclusion:The diagnostic knowledge of CHAID classification model automatically from the cases can be used to classify maxillary Ⅲ lymph nodes of breast cancer and other diseases.It is worth of widely practical use.
