Abstract: It is of great reference value for the research of prevention and cure of disease to find out the beneficial or harmful factors affecting the disease from a large number of biomedical literatures. However, it is difficult to identify the bottlenecks that are difficult to continue to improve when the accuracy of the classification is improved to a certain level by using the traditional machine learning method. In order to improve the performance of the classification task in biomedical field, the hybrid method of convolution neural network method and Support Vector Machine（SVM） is used by data with the two factors which are beneficial and harmful to disease. Ultimately, the method achieves better performance than the traditional machine learning, with the accuracy of classification from SVM increasing from 90.44% to 94.38%, so as to better identify the factors that affect the disease.
