Abstract

The invention relates to an information feature extraction method and device, a readable storage medium and electronic equipment, and the method comprises the steps: obtaining user visiting record information, constructing structured data according to the user visiting record information, constructing a feature representation of the user visiting record information based on the structured data, and extracting the feature representation of the user visiting record information; the feature representation comprises spatial features, time features and space-time features of the user visiting record information, space-time dependence features of the user visiting record information are extracted according to the spatial features, the time features and the space-time features, and the space-time dependence features are semantic relations and time sequence features between target events in multiple visiting records of the user. According to the method, the characteristics of the user visiting record information are captured from three dimensions of time, space and time-space while priori knowledge related to the user visiting record information is integrated, more robust and more accurate characteristic representation of the user visiting record information is learned, and the prediction effect of a disease prediction task is improved.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular, to an information feature extraction method, device, readable storage medium, and electronic equipment. Background technique [0002] Prediction of medical information refers to the task of using computer technology to predict the diseases that patients may suffer from in the future based on the information of historical medical records. Prediction of medical information can assist doctors to improve work efficiency and reduce the rate of misdiagnosis, and has great application value in the medical field. It is also an important research field of medical informatization. With the accumulation of a large amount of medical data and the development of data mining technology, the research on personalized medicine and precision medicine is also constantly improving. However, due to the complex, sparse, and high-dimensional characteristics of medical data, traditional da...
