Abstract

The invention discloses a medical record knowledge graph constructing method based on a dynamic graph sequence, and a system. The constructing method comprises the steps of acquiring medical record data; wherein the medical record data comprises the characteristic data of the electronic medical record and a patient; preprocessing the acquired medical record data, and determining preprocessed medical record data; constructing a case group according to the preprocessed medical record data; wherein the case graph displays multiple entities and the relation between the entities; the entities comprise medicine, symptom, disease kind and medicament kind, and the relation between the entities comprises an ownership attribute relation and a treatment relation; introducing a time dimension, defining an evolution graph sequence model by means of the case graph, and determining a medical knowledge graph which is constructed by the medical record data of the patient at different time points. The constructing method and the system according to the invention can improve efficiency in searching a disease kind by a user.

Description

technical field [0001] The invention relates to the field of medical record knowledge graph construction, in particular to a method and system for constructing a medical record knowledge graph based on a dynamic graph sequence. Background technique [0002] Today, artificial intelligence has become the core driving force of a new round of technological revolution and industrial transformation. China's artificial intelligence is currently in the stage of large-scale industrial application, and the integration of "artificial intelligence (AI) + traditional industries" is accelerating, and gradually It penetrates into many fields such as security, medical care, retail, transportation, manufacturing, and home furnishing. Among them, medical care has become the most popular research and application field in the AI ​​industry. Since 2013, the investment and financing enthusiasm in the medical AI field has also been higher than that of other industries; the Chinese government relea...
