Various internet medical platforms of the related art are in endless, and resident doctors are in good quality. Since there is no uniform standard for professional medical content, it is difficult to determine whether a doctor is authoritative by the quality of the content written by the doctor. In the related technology, when the content of the third-party internet medical platform is introduced, only the content registered as a doctor in Hospital three is selected directly, and the content is assumed to be an authoritative hospital (Hospital three is the highest-level hospital in China), namely the content representing the authority.

In the related art, assuming that a hospital in which a doctor who is resident on a third-party internet medical platform belongs is a high-authority hospital, a method representing that the authority of the doctor is higher is not accurate. There are at least three problems:

1) the first-line cities, provinces, prefectures and counties in the world, such as the northern Shangdong, all have three hospitals, and the three hospitals in China are the same, and the doctor authority degree difference of doctors in the three hospitals in different regions is obvious;

2) the experience and medical level of doctors in the same hospital at different job levels are different greatly;

3) driven by the interest of third-party internet medical platforms, some resident doctors may engage in medical information writing and inquiry activities inconsistent with the directions of their professional departments in order to obtain higher exposure and platform stimulation, and their doctors are not authoritative in the non-professional field.

The functions of the respective modules will be explained below.

The following is a description of an example in which the server of the internet medical platform described above implements the doctor evaluation method of the internet medical platform provided in the embodiment of the present invention. Referring to fig. 3, fig. 3 is a flowchart of a doctor evaluation method of an internet medical platform according to an embodiment of the present invention, which can be applied to the server of the internet medical platform described above, and will be described with reference to the steps shown in fig. 3.

In step S101, according to the hospital ranking list data, hospital authority characteristics of a hospital to which a doctor who resides on the internet medical platform belongs are acquired.

In some embodiments, the server obtains, according to the hospital leaderboard data, hospital authority characteristics of a hospital to which a doctor who resides on the internet medical platform belongs, including: the hospitals to which the doctors belong are searched out from hospital ranking lists of different grades; determining the value of the hospital authority feature of the hospital to which the doctor belongs according to the ranking of the ranking list of the hospital to which the doctor belongs; wherein, the value of the authority degree characteristic of the hospital is positively correlated with the grade of the ranking list of the hospital where the hospital is. The positive correlation comprises a linear positive correlation and a non-linear positive correlation, and when the ranking of the leaderboard of the hospital is higher, the value of the authority feature of the hospital is larger.

As an example, referring to fig. 6, fig. 6 is a schematic diagram of ranking lists of three different levels provided by the embodiment of the present invention, where the ranking list of the level a is top100 famous hospitals in China, the ranking list of the level B is 100 strong hospitals in the local city level city, and the ranking list of the level C is 300 strong hospitals in other local city level hospitals. The server assigns different hospital authority level characteristics hospital _ level to the A, B, C three hospitals with different levels, and the values of the characteristics are alpha, beta and gama. Wherein, alpha, beta and gama are arranged in descending order. The server finds out the hospitals to which the doctors belong from the A, B, C hospital ranking lists with three different grades; and determining the value of the hospital authority feature hospital _ level given by the hospital to which the doctor belongs according to the grade of the hospital ranking list.

In step S102, doctor job title characteristics of the doctor are acquired.

In some embodiments, the server obtains doctor title characteristics for the doctor, including: acquiring a detail page of a doctor, and extracting the doctor job title of the doctor from the detail page; determining the value of the doctor job title characteristic of the doctor according to the grade of the doctor job title; wherein, the value of the hospital job title characteristic is positively correlated with the grade of the hospital job title.

Referring to fig. 7 by way of example, fig. 7 is a schematic diagram of doctor detail page information provided by an embodiment of the present invention, fig. 7 shows a doctor job title 303, and the server obtains the job title of the doctor by obtaining the doctor detail page information and extracting fields for representing the doctor job title in the doctor detail page information. And giving the value of the doctor job level characteristic vector _ level according to the value corresponding to the doctor job title level.

By way of example, doctors can be generally classified into at least doctors, main doctors, assistant main doctors and main doctors according to their job title from low to high, and the higher the general grade means that the longer the time of the practitioner, the higher the authority.

In the embodiment of the invention, compared with the prior art that only the hospital to which the doctor belongs is taken as the reference information for evaluating the doctor and the job title level of the doctor is also taken into consideration, the reference information is more comprehensive and has higher reliability; the reference information of the doctor is obtained by acquiring the job title grade information of the doctor on the detail page, so that the evaluation process is more efficient and the evaluation result is more accurate.

In step S103, the doctor' S professional characteristics of the doctor are determined according to the department where the doctor is good at.

In some embodiments, referring to fig. 4, fig. 4 is a flowchart illustrating a doctor evaluation method of an internet medical platform according to an embodiment of the present invention, and fig. 4 shows that step S103 in fig. 3 can be implemented by steps S1031 to S1033 shown in fig. 4. In step S1031, a department that the doctor excels in is acquired; in step S1032, determining an information amount of a corresponding doctor according to the statistical number of times of each type of department, and taking the information amount as a department concentration; in step S1033, a value of the characteristic of the professional degree of the doctor is determined according to the concentration degree of the department.

In some embodiments, a physician-skilled department is obtained comprising: the department that the doctor excels in is extracted from the doctor's detail page. For example, referring to fig. 8, fig. 8 is a schematic diagram of doctor detail page information provided by the embodiment of the present invention, fig. 8 shows a good department 301 and a good department 302, the server extracts fields characterizing doctor good departments from the doctor detail page, and the departments filled with the doctor registration can be obtained as two good departments: department of stomatology, department of internal medicine, and record the number of times that each type of good department is counted in the doctor's detail page as the number of times that each type of good department is counted, and count the doctor's detail page as the total number; determining a ratio between the number of statistics and the total number of types of good departments as a probability of good departments of each type; taking the probability of each type of the expert departments as weight, carrying out weighted summation on the information quantity of each type of the expert departments, and taking the weighted summation result as the information quantity of corresponding doctors; wherein the amount of information for each type of good department is a logarithm of the number of statistics for each type of good department, e.g., a base 2 logarithm; using the obtained information amount of the doctor as a department concentration degree department _ conc _ score; and determining the value of the doctor specialty characteristic vector _ prof _ score according to the department concentration department _ conc _ score.

It should be noted that, when some doctors register the third-party internet medical platform, if the field indicating the expert department does not completely mark the information of the department good for the doctor, or mark the content that the department information and the actual subsequently published medical information do not belong to the same department, the information published by the doctor and/or the content title of the question and answer can be collected, and the department intention of each information and/or content title of the question and answer can be identified by a supervised machine learning method, so as to obtain the department good for the doctor.

Accordingly, in other embodiments, a physician-adept department is obtained, further comprising: matching all information and/or inquiry answers issued by the doctor in a period of time with keywords in the department knowledge graph, and taking the department corresponding to the matched keywords as the department good at the doctor. The corresponding relation between the keywords and departments is stored in the department knowledge graph in advance, when the server obtains information/inquiry answers issued by the doctor, the obtained medical contents are matched with the keywords in the department knowledge graph through simple and hard rules, according to the keywords obtained through matching, the departments corresponding to each piece of information and/or inquiry answer are found out in the corresponding relation of the department knowledge graph, and the departments to which each piece of information and/or inquiry answer of the doctor belongs are obtained. Recording the counted times of the doctor information and/or the inquiry answers of each type of the expert departments as the counted times of each type of the expert departments, and taking the count of the doctor information and/or the inquiry answers as the total number; determining a ratio between the number of statistics and the total number of types of good departments as a probability of good departments of each type; taking the probability of each type of the expert departments as weight, carrying out weighted summation on the information quantity of each type of the expert departments, and taking the weighted summation result as the information quantity of corresponding doctors; wherein the amount of information for each type of good department is a logarithm of the number of statistics for each type of good department, e.g., a base 2 logarithm; using the obtained information amount of the doctor as a department concentration degree department _ conc _ score; and determining the value of the doctor specialty characteristic vector _ prof _ score according to the department concentration department _ conc _ score.

In other examples, a department that gains physician excellence includes: the method comprises the steps of performing word segmentation processing on information and/or inquiry answers issued by doctors to extract keywords, calling a neural network model to perform classification processing on word vectors of the keywords, and obtaining departments associated with each piece of information and/or inquiry answer to serve as departments which the doctors are good at. Recording the counted times of the doctor information and/or the inquiry answers of each type of the expert departments as the counted times of each type of the expert departments, and taking the count of the doctor information and/or the inquiry answers as the total number; determining a ratio between the number of statistics and the total number of types of good departments as a probability of good departments of each type; taking the probability of each type of the expert departments as weight, carrying out weighted summation on the information quantity of each type of the expert departments, and taking the weighted summation result as the information quantity of corresponding doctors; wherein the amount of information for each type of good department is a logarithm of the number of statistics for each type of good department, e.g., a base 2 logarithm; using the obtained information amount of the doctor as a department concentration degree department _ conc _ score; and determining the value of the doctor specialty characteristic vector _ prof _ score according to the department concentration department _ conc _ score.

For example, referring to fig. 9, fig. 9 is a schematic structural diagram of a Neural Network model provided in the embodiment of the present invention, an input layer obtains Word vectors corresponding to N words in each piece of information and/or inquiry answer based on Word2vec, the Word vectors with a dimension of K pass through a convolutional layer, a pooling layer and a full-link layer, and finally, a department classification result of each piece of information and/or inquiry answer is output, the department classification result includes multiple department categories and confidence probabilities corresponding to the multiple department categories, and the department categories with the confidence probabilities exceeding confidence thresholds are used as departments associated with each piece of information and/or inquiry answer, where the Neural Network model may be a Text-CN N model or a deep learning classification model based on a Recurrent Neural Network (RNN), where N and K are positive integers.

As an example, the neural network model provided by the embodiment of the present invention classifies the department intentions based on Word2vec and Text-CNN models, and the neural network model is mainly divided into four layers:

1) an input layer: the layer mainly functions to encode each Word in the input natural language into a Word vector with uniform meaning dimension, for example, based on a vector computing tool Word2vec, the Word vector is constructed by constructing the text in the information and/or inquiry answer issued by the doctor, after the Word vector is constructed, all the Word vectors are spliced to form a two-dimensional matrix of n x K, wherein n represents the Word number of the keywords obtained by segmenting the information and/or inquiry answer issued by the doctor, and K represents the dimension of the vector.

The Word2vec algorithm performs Word segmentation on the information published by the doctor and/or the text of the inquiry answer to obtain a Word n, takes the Word in the context where the Word n is located as input, takes the Word n as output, and sets the position of the Word in the context appearing in the vocabulary to be 1, otherwise sets the position of the Word in the context to be 0, thereby mapping each Word after the Word segmentation of the information published by the doctor and/or the text of the inquiry answer into a numerical vector of a dimension K, such as an ith Word vector W in the information published by the doctor and/or the text of the inquiry answer shown in fig. 9_i＝(W_(i,1)，W_(i,2)，…，W_(i,K)) Wherein W is_(i,K)To representWhether the corresponding value of the vocabulary i appears at the position of the K-th dimension of the vocabulary table or not is judged, and therefore word vectors of the keywords after word segmentation processing is carried out on the information published by a doctor and/or the text of an inquiry answer are obtained.

It should be noted that, in order to perform model training on the information and/or inquiry responses issued by the doctor, vectorization processing needs to be performed on the information and/or inquiry response text issued by the doctor, so that vectorization representation, that is, the above-mentioned process of converting the information and/or inquiry response text issued by the doctor into a numerical vector, needs to be performed. Word2vec can reflect approximate relation of semanteme and co-occurrence frequency relation between words, and can convert words with close semanteme in information and/or inquiry answer text published by a doctor or words with higher co-occurrence frequency in the information and/or inquiry answer text published by the doctor into vectors with closer spatial positions, and the higher the similarity between the vectors is, the closer the semanteme is.

In the embodiment of the invention, a Word vector model with low dimensionality is generated through a Word2Vec model and is used for calculating the similarity between words; word2vec considers context, and can better represent Word similarity; the vector dimensionality obtained by Word2vec is less, so that the calculation cost of classification is lower, and the classification speed is higher; and Word2vec has strong universality, and can be used in various Natural Language Processing (NLP) tasks.

2) And (3) rolling layers: this layer is mainly characterized by convolution processing. The input information and/or the inquiry answer text are converted into a two-dimensional matrix with the size of n x K after passing through the input layer, and the subsequent convolution work is carried out on the two-dimensional matrix with the size of n x K. The size of the convolution kernel is generally set to t × K, t is the length of the convolution kernel, K is the width of the convolution kernel, and this width is set to be the same as the dimension of the word vector, and the convolution operation is performed only along the text sequence, where t may have various choices, such as 2, 3, 4, 5, and so on. In the Text-CNN model, multiple convolution kernels of different types can be used simultaneously, and there can be multiple convolution kernels of each type size.

3) Maximum pooling layer: and taking the maximum value of a plurality of vectors obtained after convolution, and then splicing the vectors into one block to be used as the output value of the layer. If the sizes of the convolution kernels are 2, 3, 4 and 5, and there are 1024 convolution kernels in each size, 4 × 1024 one-dimensional vectors are obtained after convolution and 4 × 1024 values are obtained after maximum pooling. The significance of the maximum pooling layer is to extract the most active features for the convolutional layer.

4) Full connection layer: and integrating all the features obtained after the pooling treatment together to obtain a feature vector of 4096 x 1 of the final structure. The last layer of full connection layer is connected with a classification system, the output value of the full connection layer is transmitted to the classification system, the classification system can adopt logistic regression softmax (softmax re regression) to classify the information and/or inquiry answer issued by the doctor, and the information and/or inquiry answer issued by the doctor are obtained to belong to the department type, so as to be used as the department which the doctor excels in. In order to improve the learning ability of the neural network model in the actual implementation process, a plurality of fully connected layers can be connected.

It should be noted that, when determining the department good at by the doctor according to the detail page or the inquiry answer of the doctor, the statistical number of times of the good department is +1, until all the detail pages and the inquiry answers of the doctor are traversed, the statistical number of times of each type of department good at by the doctor is obtained. Department concentration, specifically the amount of information of the doctor; the amount of information of the doctor is a result of weighted summation of the amount of information of each type of department that the doctor excels in.

For example, the department concentration profile may be as shown in equation (1):

department_conc_score(X)＝-∑_x∈Xp(x)log₂p(x) (1)

wherein x represents the type of department that the physician is skilled in; x represents the total number, i.e., the physician's details page and/or the count of the inquiry answers; p (x) represents the probability of each type of good department, i.e. the ratio between the number of statistics and the total number of good departments per type.

And determining the value of a doctor specialty characteristic vector _ prof _ score according to the department concentration ratio, wherein (i) partial _ conc _ score (X).

In the embodiment of the invention, the department intentions are classified based on the Word2vec and Text-CNN models, so that the models are simple, the speed is higher, and the departments which doctors are good at can be accurately classified.

In step 104, the hospital authority feature, the doctor job title feature and the doctor specialty feature are fused to obtain the doctor authority of the doctor.

In some embodiments, fusing the hospital authority feature, the doctor job title feature, and the doctor specialty feature to obtain the doctor authority of the doctor includes: taking a square value of the professional degree characteristics of the doctor, and calculating the reciprocal of the square value; and multiplying the hospital authority characteristic, the doctor title characteristic and the reciprocal of the square value of the doctor specialty characteristic, and taking the multiplication result as the doctor authority of the doctor.

For example, the physician authority may be as shown in equation (2):

wherein, square (sector _ prof _ score (i)) means to square the professional characteristics of the doctor. It is worth explaining that, in order to increase the influence discrimination of the doctor specialty features on the final doctor authority value, the doctor specialty features are squared.

In some embodiments, based on the department information identified from the doctor's details page and the published questions and answers measuring the doctor's department concentration, different departments in the department concentration are weighted according to the feedback information published by the doctor for each department. For example, feedback information such as the number of times of approval and comment of the user on the inquiry response and the like is used as the weight of the doctor information amount according to the information published by each department, and the department concentration formula is updated through the obtained weight of the doctor information amount.

It should be noted that in some embodiments, the doctor's adept department may be predicted only by the department knowledge graph or the neural network model, and in other embodiments, the department knowledge graph or the neural network model may be combined with the department that the doctor is adept at extracting from the doctor detail page, that is, when no department information is extracted from the doctor detail page, the doctor's adept department may be predicted by the department knowledge graph or the neural network model. By the method of department knowledge map or neural network model prediction, even if department information is not extracted from the field of the detail page, the department which the doctor excels in can be accurately determined; and updating the weights of different types of departments adept in the department concentration ratio according to the feedback information, so that the evaluation information is more accurate.

In some embodiments, referring to fig. 5, fig. 5 is a flowchart illustrating a doctor evaluation method of an internet medical platform according to an embodiment of the present invention, and based on fig. 3, after step S104, the following steps may be further performed:

in step S105, in response to the inquiry request, acquiring an inquiry answer corresponding to the inquiry request; wherein, the doctor authority value of the candidate doctor who issues the inquiry answer is larger than the authority threshold value;

in step S106, a plurality of candidate doctors and corresponding inquiry answers are displayed in an inquiry page.

In some embodiments, a terminal user opens an internet medical page to send an inquiry request, a server receives the inquiry request sent by the terminal user, acquires inquiry inquiries related to the inquiry request, acquires doctor authority degrees of doctors issuing the inquiry inquiries, selects doctors with the doctor authority degree values larger than an authority degree threshold value K as candidate doctors, and displays the candidate doctors and the internet medical pages of the inquiry answers corresponding to the candidate doctors when responding to the inquiry request. In the embodiment of the invention, the server can intelligently recommend doctors with high doctor authority and written inquiry answers according to inquiry requests of users, and by the mode, the internet medical platform can be kept to be obviously higher than the average level of other third-party internet medical platforms in the aspect of doctor authority.

According to the doctor evaluation method of the internet medical platform, provided by the embodiment of the invention, the doctor authority is considered from three dimensions of the hospital authority, the doctor title level and the department concentration, accurate evaluation information is provided for a doctor who resides in the internet medical platform, and an authoritative good doctor and issued content on a third-party internet medical platform can be carefully and accurately screened out according to the evaluation information.

In the following, an exemplary application of the embodiments of the present invention in a practical application scenario will be described.

The embodiment of the invention can be applied to an internet medical platform, such as doctor screening, namely displaying medical contents of authoritative doctors for users, as shown in fig. 1a, a terminal 400 is connected to a server 200 (hereinafter, referred to as server 200) of an internet medical platform through a network, a client 410 (e.g., a medical dictionary APP) is installed on the terminal 400, a user accesses the server 200 of the internet medical platform through the client 410 to perform an inquiry, the internet medical platform sends an inquiry request sent by the user to the server 200 through the network, the server 200 executes a doctor evaluation method of the internet medical platform provided by an embodiment of the present invention, and evaluating the doctors writing the inquiry answers corresponding to the inquiry requests, predicting the authority of the doctors, selecting the doctors with the authority values larger than the authority threshold value as candidate doctors, and sending the candidate doctors and the corresponding inquiry answers to the client 410 for presentation.

Referring to fig. 10, fig. 10 is a schematic diagram of an inquiry page in an internet medical platform according to an embodiment of the present invention. Fig. 10 shows hospitals to which doctors who issue inquiry responses on the inquiry page belong, and it can be understood that the inquiry responses displayed on the inquiry page are issued by doctors in the third hospital. In the implementation process of the embodiment of the invention, the following relevant technologies are found: when the hospital where the resident doctor on the third-party internet medical platform belongs is a high-authority hospital, the doctor authority of the doctor is judged to be high, and the produced content authority is good. This method has at least three problems:

3) driven by the interest of third-party internet medical platforms, some resident doctors may engage in medical information writing and inquiry activities inconsistent with the professional direction of the good department in order to obtain higher exposure and platform stimulation, and the doctors are not authoritative about the published medical contents in the non-professional field.

In order to solve the problems, the embodiment of the invention adopts a doctor evaluation method of an internet medical platform, the doctor authority is considered from three dimensions of the hospital authority, the doctor job title level and the department concentration, accurate evaluation information is provided for a doctor who resides in the internet medical platform, and an authoritative good doctor and issued content on a third-party internet medical platform can be carefully and accurately screened out according to the evaluation information.

According to the doctor evaluation method of the internet medical platform, provided by the embodiment of the invention, the doctor authority is comprehensively obtained according to the hospital authority characteristic, the doctor title characteristic and the department concentration characteristic, accurate evaluation information is provided for a doctor who resides in the internet medical platform, and the authority of the doctor who resides in the internet medical platform can be carefully and accurately evaluated according to the evaluation information.

Aiming at the three problems of the related technology, the doctor evaluation method of the internet medical platform provided by the embodiment of the invention classifies three corresponding characteristics, namely hospital authority characteristic, doctor title characteristic and doctor professional characteristic.

1) According to the hospital ranking list accepted in the industry, the hospital ranking list entering the compound medical ranking list and the Ailisi hospital ranking list in the last 5 years is collected in the ranking list system, for example, referring to FIG. 6, the ranking list of the A level is top domestic top hospital, the ranking list of the B level is 100 strong hospitals in the local city level city, and the ranking list of the C level is 300 strong hospitals in other local city level hospitals. A, B, C, three hospitals with three different levels are endowed with different hospital authority level characteristics hospital _ level, and the values of the hospital authority level characteristics are alpha, beta and gama. Wherein, alpha, beta and gama are arranged in descending order.

2) Referring to fig. 7, fig. 7 shows the job title 303, doctors can be generally classified into at least a main doctor, a subordinate main doctor and a main doctor according to their job titles from low to high, and the higher the grade generally means that the longer the time of the practitioner, the higher the authority. And extracting corresponding fields for representing the job titles of the doctors from the doctor detail page information by grabbing the doctor detail page information. And for the doctor job level feature vector _ level, giving the value of the doctor job level feature vector _ level according to the value corresponding to the doctor job title level.

3) Referring to fig. 8, in fig. 8, the more intensive are the departments which are good at by the doctor, the more intensive are the departments to which the contents of the published information/inquiry answers relate, and the more authoritative the doctor is in the corresponding field, which is shown as a good department 301 and a good department 302. The physician's good department set is determined by two steps of extraction + identification. The 'good' field in the doctor detail page is extracted, and then departments filled with the doctor registration, such as 'oral departments' and 'internal departments', are identified as the departments good for the doctor.

Considering that some doctors register the third-party internet medical platform, the "good at" field does not completely mark department information, or marks that the department information and actual subsequently published medical information do not belong to the same department. Therefore, after identifying the detail page, it is necessary to collect all the information/content titles of the inquiry answers issued by the doctor, and identify the department intentions of each content title by the supervised machine learning method. For example, when performing department intent classification, the department category may be about 50 departments existing in the field of physicians, and solved using 50 classifiers. There are several implementations here: a. performing simple hard rule matching on all information/content titles of inquiry questions and answers issued by the doctor based on the artificial medical-department knowledge map, and identifying the department intentions associated with all the information/content titles of inquiry questions and answers issued by the doctor; b. the method comprises the steps of manually labeling hundreds of positive sample data of each department intention in advance, randomly sampling the corresponding negative sample data of other department category positive sample data which do not belong to the department, then training a department intention classifier by using a deep learning model based on Word2vec Word vectors and a Text-CNN model proposed by Kim in 2013, and classifying information/inquiry answers issued by doctors based on the trained department intention classifier.

Referring to fig. 11, fig. 11 is a schematic diagram of partial inquiry answers issued by the doctor according to the embodiment of the present invention, and it can be known from the department classification model that the department skilled in the doctor also issues contents of departments such as "gynecology," "ophthalmology," "dermatology," and "endocrinology," in addition to the extracted "oral cavity" and "internal medicine" above. An information entropy algorithm is introduced to calculate department concentration characteristic of the content published by the doctor, the lower the entropy is, the higher the department concentration is, the more the doctor focuses, and the more authoritative the doctor is in the professional field.

The department concentration characteristic may be as shown in equation (1):

department_conc_score(X)＝-∑_x∈Xp(x)log₂p(x) (1)

Determining the value of a doctor specialty characteristic vector _ prof _ score according to the department concentration, wherein i represents a doctor identifier.

Based on the values calculated in 1), 2), 3), the authority factor _ auth _ score algorithm formula (2) of doctor i can be calculated as follows:

wherein, square (sector _ auth _ score (i)) refers to the operation of squaring the professional characteristics of the doctor. It is worth explaining that, in order to increase the influence discrimination of the doctor specialty features on the final doctor authority value, the doctor specialty features are squared.
