Problems solved by technology

However, the relevant information of an insurance claim case contains a lot of time and place, such as the time of reporting the case, the time of seeing the doctor, the place of reporting the case, and the place of seeing the doctor. Information is lost during the process, and the identification accuracy of high fraud risk cases cannot be guaranteed

Abstract

The invention discloses a high-fraud-risk case identification method and apparatus, and a computer device, relates to the technical field of information, and mainly aims to improve the identification precision of high-fraud-risk cases. The method comprises the steps of obtaining attribute information corresponding to a to-be-identified case, wherein the attribute information comprises time information and position information; inputting each piece of attribute information into a preset spatial-temporal feature extraction model for feature extraction to obtain a spatial-temporal feature vector corresponding to the to-be-identified case; calculating the similarity between the to-be-identified case and a first sample high-fraud-risk case based on the spatial-temporal feature vector corresponding to the to-be-identified case and the spatial-temporal feature vector corresponding to the first sample high-fraud-risk case; and judging whether the to-be-identified case is a high-fraud risk case or not according to the calculated similarity. The method is suitable for identifying high-fraud risk cases.

Description

technical field [0001] The present invention relates to the field of information technology, in particular to a method, device and computer equipment for identifying high fraud risk cases. Background technique [0002] With the gradual increase of insurance claim cases, there will be some cases of malicious insurance fraud insurance companies, which will bring economic losses to insurance companies. Therefore, how to effectively identify high fraud risk cases is a technical problem that needs to be solved urgently. [0003] Currently, high fraud risk cases are usually identified by gradient boosting machines. However, the relevant information of an insurance claim case contains a lot of time and place, such as the time of reporting the case, the time of seeing the doctor, the place of reporting the case, and the place of seeing the doctor. In the process of losing information, the identification accuracy of high fraud risk cases cannot be guaranteed. Contents of the inven...
