Abstract

The invention provides an index extraction method and device based on a knowledge graph. The method comprises the steps of obtaining the information of a patient; performing structured processing on the information of the patient to obtain structured information of the patient; determining reference indexes required by research according to the structured information of the patient and the research target; obtaining values of the reference indexes at different time points; and combining the reference index values of the different time points with the knowledge graph, and determining the reference index corresponding to at least one time point in the different time points as a final research reference index. Indexes to be referenced by research are determined according to patient information and research purposes. And numerical values of the determined indexes at different time points are obtained, the numerical values are compared with an existing knowledge graph, and the indexes are screened and calibrated by using the knowledge graph, so as to obtain indexes which can be based by research. The indexes are not clear in the knowledge graph and are determined through research.

Description

Technical field [0001] The present invention relates to the field of medical research technologies, and more particularly to an indicator extraction method and apparatus based on a knowledge map. Background technique [0002] The tumor is a disease that seriously threatens human life, and its treatment has a long period of time, a variety of schemes, and complex process complex. In recent years, the disease database or knowledge base has ushered in greater development, and there have been trends based on medical data / knowledge storage libraries. More of these databases are only simple storage for medical data / knowledge, and the researchers need to decide and extract research indicators based on their own expertise. Medical Research Investing out the effects of a treating solution, requiring the effects of past treatment and follow-up, and researchers need to spend a lot of time and energy in many point in time when launching research. The influence of the status on related in...
