Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic flow chart of a user service request processing method according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
step 101: acquiring application information of a user who has applied for a target service and health state information of the user.
The application information of the target service applied by the user can be obtained from the database, and the first time of the target service is further obtained from the application information of the target service applied. The target service may be an insurance or mutual aid claim service, and the first time may be a time to invest or join in mutual aid. For example, the target service is a health insurance, the user completes the insurance application operation of the health insurance at the time A, and the user proposes a claim based on the health insurance at the time B, wherein the time B is later than the time A. According to the operation step of step 101, the insurance application information of the user about the health insurance can be obtained in the database, and the insurance application time can be determined according to the insurance application information.
The method for acquiring the health state information of the user comprises the following steps:
the first acquisition mode: and acquiring the personal health state information submitted by the user. Specifically, when the user requests the requested target service, a copy of the health status information of the user is provided according to the corresponding requirement, that is, the health status information of the user provided in the service requesting stage can be acquired.
The second acquisition mode is as follows: and acquiring the health state information of the user in the corresponding information management system. Specifically, the user information of the corresponding user may be determined according to the application information of the applied target service, and the health status information of the user may be acquired in the corresponding information management system according to the user information.
In an implementation manner, in order to reduce the working strength of the target service platform, the first obtaining manner may be set as a default obtaining manner, and if an abnormal condition occurs in the health state information obtaining operation stage of the user based on the first obtaining manner, the health state information of the user may be obtained through the second obtaining manner. Wherein the abnormal condition includes:
in the first case:
and determining that the age of the user is greater than the set age in the stage that the user requests the requested target service.
In this case, the target service platform may determine that the user is an elderly person, and may not be skilled in the network platform to acquire the health status information of the user, and the target service platform may be acquired instead. Specifically, when the target service platform requests the requested target service, and the platform determines that the age of the user is greater than the set age, the target service platform may send a prompt message to the user, and the user may click an option in the prompt message to select whether the platform is required to obtain the health status information. If the user authorization platform is obtained instead, the target service platform can obtain the health state information of the user in the corresponding time period in the corresponding information management system based on the identity information of the user and the corresponding file of the applied target service.
In the second case:
the detection time of the health status information submitted by the user is after the first time.
In this case, the target service platform may determine that the temporal coverage of the health status information provided by the user is low. For example, the target service is a health insurance, the user completes the insurance application operation of the health insurance at the time A, the user proposes a claim based on the health insurance at the time B, and the user provides the health status information of the user after proposing the claim. However, the detection time of the target service platform detecting the health status information provided by the user is all later than the A time. In order to ensure the time coverage of the health state information of the user, the target service platform can acquire the health state information of the user in a corresponding time period in a corresponding information management system based on the identity information of the user and a corresponding file of the applied target service.
In one implementation, the health status information may include an electronic medical record and/or a physical examination report. The electronic medical record can be an electronic medical record of a user in one or more hospitals, and the physical examination report can be a physical examination report of the user in a hospital or a physical examination center. If the target service platform needs to acquire the electronic medical record of the user, the electronic medical record of the user can be acquired in the electronic medical record management system based on the identity information of the user and the corresponding file which applies for the target service.
In an implementation manner, the health status information of the user may be obtained by simultaneously adopting the first obtaining manner and the second obtaining manner.
The electronic medical records can comprise electronic medical records which are uploaded to an electronic medical record management system by all hospitals where the user visits at one time, and the electronic medical records can specifically comprise electronic medical records for outpatient service and electronic medical records for hospitalization.
Step 102: and extracting the disease name and the corresponding disease time from the health state information of the user.
The electronic medical record acquired in step 101 may be in a picture format or a PDF format, and after the electronic medical record is acquired, the electronic medical record in the picture format or the PDF format may be identified as a text form based on a character recognition technology (e.g., Optical Character Recognition (OCR)), and the texts identified by the OCR are recombined into a section of medical record text. If the acquired electronic medical records of the user comprise the electronic medical records for hospitalization, the medical record texts corresponding to the electronic medical records for hospitalization can be classified, and specifically, the medical records for hospitalization and the medical records for discharge can be respectively processed.
Case (considering user privacy and convenience of example and writing, here simplifying electronic medical records and their format):
name: king certain;
the admission time is as follows: 2020-3-15
The current medical history: the patient was admitted to the hospital in a heart attack burst 2 weeks before.
History of the past: none.
And (4) obtaining a result after extraction: { history of present disease: [ {2020-3-1: Heart disease } ]
According to the character information identified in the electronic medical record, the admission time of Wangzhizi of the patient is 2020-3-15, the extracted disease name is heart disease, and the illness time is 2 weeks before the admission time. Based on a rule engine in the entity recognition model, the relative time can be converted into absolute time, namely, the affected time of the patient Wangzao is 2020-3-1, and the entity recognition model outputs a recognition result: patient wangzhi { current medical history: [ {2020-3-1: heart disease } ] }.
Step 103: comparing the illness time of the disease extracted in the step 102 with the first time of the target service acquired in the step 101, if the illness time is earlier than the first time, adding a first label to the user target service application information, and if the illness time is later than the first time, adding a second label to the user target service request information.
If the first time of the target service of the user (the Wangzao) is 2020-3-20, the time of the Wangzao suffering from the disease (the heart disease) can be determined to be earlier than the first time (such as the insurance time of health insurance). Further, a first tag may be added to the information of the target service application of wang, and the information of the target service application of wang to which the first tag is added is stored in a database of the target service platform, and a subsequent user application qualification management system or a worker who performs manual review may review the information of the target service application to which the tag is added in the database, and the tag (the first tag or the second tag) in the information of the user target service application may be used as a reference to determine whether the user qualifies for applying for the target service. Specifically, the tag in the information of the wangzao target service application is a first tag, and the result of the audit on the wangzao target service application is as follows: prior disease (heart disease) and no claim qualification.
In this embodiment, the steps 102-103 are executed by the entity identification model provided in the present application, and the entity identification model may be further constructed before the step 102 is executed, and the construction process of the entity identification model is as follows:
1. sequence labeling is carried out on the identified medical record texts, and labeling can be carried out in a BIEO labeling mode.
BIEO in the BIEO notation is the first letter of the four words Begin, Intermediate, End, Other. The BIEO labeling means is to label that each word belongs to the beginning, middle or end of a named entity, or belongs to another.
Fig. 2 is a schematic labeling diagram of a BIEO labeling manner provided in an embodiment of the present invention, and as shown in fig. 2, in the BIEO format labeling performed on medical record text data, specifically, B-leave: the starting character of a DISEASE, I-DISEASE: middle character of a certain DISEASE, E-away: ending character of a certain disease, O: non-disease character, S.disease is a single word.
As shown in fig. 2, after the DISEASE name "gastric mucosal lesion" in the electronic medical record is divided into five characters, i.e., "stomach", "mucosa", "membrane", "DISEASE" and "lesion", the named entity label information of "stomach" is "B-DISEASE", "mucosa", "membrane" and "DISEASE" is "I-DISEASE", and the named entity label information of "lesion" is "E-DISEASE" according to the contextual characteristics of the word segmentation.
2. Entity recognition model offline training based on BilSTM + CRF
Fig. 3 is a schematic flow chart of an offline training model according to an embodiment of the present invention, and as shown in fig. 3, the offline training of the entity recognition model based on BiLSTM + CRF includes the following steps:
and 2.1, carrying out exploratory analysis on the medical record text data.
The exploratory analysis mainly analyzes the distribution of the text length, and the text length with proper size is selected to cut the text when the entity recognition is carried out, so that the accuracy of the model is improved. In general, the text length in the medical record is about 1000, so it is best to keep the text length at 1000 to do the stage. Since the longest sequence length supported by Bert is 512. So 512 sequence lengths are used as text truncation lengths in this embodiment.
2.2, loading a Bert pre-training model.
The disease entity recognition part of the scheme is also loaded with a Bert Chinese pre-training model. And loading a Bert pre-training model, and mapping based on the Bert pre-training model to obtain a word vector of each character in the training text. And the recognition task of the medical disease named entity can be further completed by following Bilstm and CRF after Bert.
2.3 entity recognition model training

The data of the model training is N M, N is BATCH _ SIZE SIZE, and M is vector latitude SIZE. The word vector after being mapped by the Bert is input into a bidirectional LSTM neural network for learning, and the learned vector is further transmitted into a Conditional Random Fields (CRF) structure for learning. Conditional probability needs to be calculated for the CRF processing sequence labeling problem, and the final class probability is calculated by adopting a maximum likelihood method through a dimension bit algorithm.
2.4 model parameter adjustment and optimization verification
And testing the trained entity recognition initial model, and taking the trained entity recognition initial model with the accuracy rate higher than the set accuracy rate as the entity recognition model according to the test result.
