Background

Clinical skills are the most valuable wealth in the medical field and the most difficult skills to learn and exercise. The mastery and promotion of clinical skills are acquired through a large amount of practices. However, in traditional medical teaching, medical students or interns mostly observe the clinical process of doctors, are difficult to contact patients in person, and rarely encounter typical and targeted cases. The assessment and evaluation of students also do not have objective, standard measures because they face patients that differ significantly from the case. Standardized Patients (SP), also called simulated Patients (Simulant Patients), refer to normal persons or Patients who can accurately express the actual clinical problems of the Patients after Standardized and systematic training, the SP plays multiple roles of acting as Patients, acting as evaluators and teachers through realistic simulation and teaching guidance of clinical environment and patient problems, can increase the chances of students contacting the Patients, provides a standard uniform and objective and fair teaching and evaluation method, is beneficial to culturing good occupational literacy and clinical thinking, thereby solving the problems and improving the effectiveness of teaching and evaluation.

However, SPs typically employ a means of personnel training, i.e., recruiting people for a collection of medical requirements, to perform a significant amount of training to enable them to play the role of standardized patients. The standardized patient training cost is high, the training period is long, and the requirements of medical teaching and evaluation cannot be met.

Reference herein to a "doctor" is to be taken to mean in particular a intern or a student.

The first machine learning algorithm and the second machine learning algorithm according to the embodiment of the present invention are used to distinguish different machine learning algorithms, where the difference refers to the difference of training data. The first machine learning algorithm and the second machine learning algorithm can be traditional machine learning algorithms, neural network algorithms and the like.

The method for simulating the patient inquiry dialogue according to the embodiment of the present invention may be applied to a Terminal device, which may also be referred to as a Terminal (Terminal), a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), or the like. The terminal device may be a mobile phone (mobile phone), a tablet computer (Pad), a computer with a wireless transceiving function, a Virtual Reality (VR) terminal, an Augmented Reality (AR) terminal, and so on.

The terminal device acts as a role of a standardized patient in the training and evaluation process of clinical medical skills by executing the method for simulating the patient inquiry dialogue, and a user using the terminal device can act as a role of a doctor to automatically perform inquiry dialogue with the terminal device, so that the effect of simulating the patient inquiry is achieved. The user can use the terminal equipment to practice and evaluate the clinical medical skill, and compared with a method of training a real person, the training cost can be reduced, and the training period can be shortened.

Fig. 1 is a flowchart of a first method for simulating a patient inquiry session according to an embodiment of the present invention, and as shown in fig. 1, the method of this embodiment may include:

step 101, obtaining an inquiry statement input by a user.

Wherein the user may be a user of the above-mentioned terminal device, who plays a role of a doctor, during practice and evaluation of clinical medical skills, and the inquiry sentence may be a sentence inquiring the terminal device, which plays a role of a standardized patient, to determine the disease of the standardized patient according to a response sentence fed back from the terminal device, for example, the inquiry sentence may be "ask for your last name? "," you good, where you are uncomfortable "," do you get a fever ", etc.

Specifically, the specific implementation manner for acquiring the inquiry sentence input by the user may be a plurality of different implementation manners. One specific implementation manner is to receive a voice signal input by a user, perform voice-to-text conversion on the voice signal, and acquire the inquiry sentence. It can be understood that the inquiry statement input by the user may be received, that is, the user inputs the text through the peripheral of the terminal device, so that the terminal device obtains the inquiry statement. Other implementation manners are also possible, and the embodiment of the present invention is not limited thereto.

And 102, searching a first answer sentence corresponding to the inquiry sentence in the inquiry matching template.

The inquiry matching template comprises a matching rule and a response sentence corresponding to the matching rule. The matching rule is used for matching the inquiry statement. The specific implementation manner of matching may be regular matching, keyword matching, and the like, and the embodiment of the present invention is not limited thereto.

Specifically, the inquiry matching template may include one or more matching rules and response sentences corresponding to the matching rules, in this embodiment, after acquiring an inquiry sentence, a matching rule matching the inquiry sentence may be searched in the inquiry matching template, if there is a matching rule matching the inquiry sentence, an response sentence corresponding to the matching rule is acquired, and the response sentence corresponding to the matching rule is the first response sentence, and the following step 103 is executed. If there is no matching rule matching, the following step 104 is performed.

For example, the matching rule is: your family name, the answer sentence corresponding to the matching rule is: i surname king, I have a whole body and generate heat. If the inquiry sentence is "ask for your maiden name? If yes, the inquiry statement matches the matching rule, and the answer statement corresponding to the matching rule is the first answer statement. That is, the first answer sentence corresponding to the inquiry sentence is stored in the inquiry matching template, the following step 103 is executed.

If the inquiry statement is "do you have a fever", the inquiry statement does not match the matching rule, i.e. there is no answer statement corresponding to the inquiry statement in the matching template, then the following step 104 is executed.

Step 103, if a first answer sentence corresponding to the inquiry sentence exists in the inquiry matching template, outputting the first answer sentence to the user.

There are various specific implementations of outputting the first answer sentence to the user, for example, performing text-to-speech conversion on the first answer sentence, and outputting a speech signal of the first answer sentence. It is understood that the text of the first answer sentence may also be directly output, or a voice signal and text may also be output, which is not limited in the embodiment of the present invention.

And 104, if the answer sentence does not exist, determining a corresponding second answer sentence according to the semantic attribute type of the inquiry sentence, and outputting the second answer sentence to the user.

The semantic attribute category of the embodiment of the present invention may include any one or more of a symptom category, a pain category, a transition semantic category, and other semantic categories, and may be flexibly set according to a requirement. When the first answer sentence corresponding to the inquiry sentence does not exist in the inquiry matching template, the semantic attribute category of the inquiry sentence can be determined, and the corresponding second answer sentence is determined according to the semantic attribute category of the inquiry sentence.

There are various specific implementations of outputting the second answer sentence to the user, for example, performing text-to-speech conversion on the second answer sentence, and outputting a speech signal of the second answer sentence. It is understood that the text of the second answer sentence may also be directly output, or a voice signal and text may also be output, which is not limited in the embodiment of the present invention.

A specific implementation manner of the step 104 is as follows: and analyzing the inquiry sentences according to the pathological knowledge base corresponding to the semantic attribute categories of the inquiry sentences to obtain second response sentences corresponding to the inquiry sentences.

Wherein the pathology knowledge base is formed from medical records of each standardized patient, which may include various symptoms, various pain sites, and the like. And the second answer sentence obtained according to the pathology knowledge base conforms to the medical record, so that the simulation of the standardized patient is realized.

In this embodiment, by obtaining an inquiry statement input by a user, a first answer statement corresponding to the inquiry statement is searched for in an inquiry matching template, and if the first answer statement corresponding to the inquiry statement exists in the inquiry matching template, the first answer statement is output to the user; if the answer sentence does not exist, the corresponding second answer sentence is determined according to the semantic attribute category of the inquiry sentence, the second answer sentence is output to the user, automatic inquiry dialogue is achieved with the user, the effect of simulating the inquiry dialogue of the patient is achieved, the answer sentence can be applied to practice and evaluation of clinical medical skills, compared with a mode of training a real person, the training cost can be reduced, and the training period can be shortened.

The technical solutions of the above method embodiments are described in detail below using several specific examples.

Fig. 2 is a flowchart of a second embodiment of the method for simulating a patient inquiry session, as shown in fig. 2, the method of this embodiment may include:

step 201, obtaining an inquiry statement input by a user.

Step 202, searching a first answer sentence corresponding to the inquiry sentence in the inquiry matching template.

And 203, if a first answer sentence corresponding to the inquiry sentence exists in the inquiry matching template, outputting the first answer sentence to the user.

For the detailed explanation of the above steps 201 to 203, refer to steps 101 to 103 in the embodiment shown in fig. 1, which are not described herein again.

For example, the inquiry sentence asked by the user is: "you are good, where you are uncomfortable". The matching rule is ". times.discomfort", the answer sentence corresponding to the matching rule is "pain of the whole body of oneself", the matching template includes the matching rule and the answer sentence corresponding to the matching rule, and then the answer sentence of the inquiry sentence can be determined as "pain of the whole body of oneself" through the above steps 201 to 203.

And 204, if the query statement does not exist, determining the semantic attribute type of the query statement.

The determination of the semantic attribute category of the inquiry statement can be determined by using a machine learning algorithm, specifically, the inquiry statement is classified by using a second machine learning algorithm, and the semantic attribute category of the inquiry statement is determined; the second machine learning algorithm is obtained by training by using an inquiry statement and a semantic attribute class corresponding to the inquiry statement.

The semantic attribute category referred to herein may be flexibly divided according to requirements, for example, the semantic attribute category may be divided into four categories, including a symptom category, a pain category, a transition semantic category, and other semantic categories, which are used for example and explanation in the embodiments of the present invention. It is to be understood that the semantic attribute category may also be other specific categories, which is not limited in the embodiment of the present invention.

The inquiry sentences belonging to the symptom category are used for inquiring whether the patient has any symptom, for example, the inquiry sentences are sentences with similar semantics such as "do you have fever", "do you have hemoptysis", and the semantic attribute category of the inquiry sentences is the symptom category.

The inquiry sentences belonging to the pain category are used for inquiring whether the patient has pain, for example, the inquiry sentences are sentences with similar semantics such as "do you have headache", "do you have joint pain", "do you have abdomen pain", and the semantic attribute category of the inquiry sentences is the pain category.

The inquiry sentences belonging to the category of transition sentences are used for inquiring whether the patient has a question, for example, the inquiry sentences are sentences with similar semantics such as "whether you have any question", "what you have to supplement", and the like, and the category of semantic attribute of the inquiry sentences is the category of transition sentences.

Other semantic categories: other classes that do not belong to the above categories, classified as not explicitly intended, cannot locate a category.

When semantic attribute categories of the inquiry statement include: when at least one of the symptom category and the pain category is selected, steps 2051 to 2053 are performed, and when the semantic attribute category of the inquiry sentence includes: if the semantic attribute type is a transition semantic type, step 2061 to step 2062 are executed, and if the semantic attribute type does not belong to any of the above symptom type, pain type and transition semantic type, that is, belongs to another semantic type, step 207 is executed.

And step 2051, acquiring keywords of the inquiry sentence.

The obtaining of the keywords may adopt various existing keyword extraction methods, for example, methods based on multi-pattern matching of a keyword thesaurus, word correlation ordering, and the like, which are not illustrated here.

For example, the inquiry sentence asked by the user is: "do you get fever". Since there is no matching rule in the matching template that matches the inquiry statement, it is determined through the above steps 201 to 202 that there is no first answer statement corresponding to the inquiry statement in the inquiry matching template, the semantic attribute category of the inquiry statement is determined through step 204, the semantic attribute category of the inquiry statement is a symptom category, and the keyword of the inquiry statement is obtained through step 2051, and the keyword is "fever".

And step 2052, searching keywords of the inquiry statement in a pathology knowledge base corresponding to the semantic attribute category of the inquiry statement.

Specifically, the keywords of the inquiry sentence are searched in the pathology knowledge base corresponding to the symptom category and/or the pathology knowledge base corresponding to the pain category. Wherein the pathology knowledge base corresponding to the symptom category may comprise a symptom list, i.e. comprise one or more symptoms, such as fever, cough, etc. The pathology knowledge base corresponding to the pain category may include a list of pain, i.e., one or more pain sites, e.g., joints, left abdomen, throat, etc.

The inquiry sentences asked by the user are as follows: by way of further illustration, by way of example, "do you have fever," the keyword is "fever," and the keyword "fever" is looked up in the pathology knowledge base, via step 2052.

And step 2053, generating a second response sentence corresponding to the inquiry sentence according to whether the keyword of the inquiry sentence exists in the pathology knowledge base.

Specifically, if the keyword of the inquiry sentence exists in the pathology knowledge base, the second answer sentence is generated, and the second answer sentence may be a positive answer, and if the keyword of the inquiry sentence does not exist in the pathology knowledge base, the second answer sentence may be a negative answer.

The inquiry sentences asked by the user are as follows: as a further example, the term "do you have a fever" is searched in the pathological knowledge base corresponding to the semantic attribute category of the inquiry sentence, and a second response sentence is generated through step 2053, specifically, for example, if the term exists, the second response sentence is "i have a fever", or "i have a sustained fever, 37.8 degrees", and the like, and if the term does not exist, the second response sentence is "i do not have a fever".

Step 2061, obtaining the keywords of the inquiry statement.

The obtaining of the keywords may adopt various existing keyword extraction methods, for example, methods based on multi-pattern matching of a keyword thesaurus, word correlation ordering, and the like, which are not illustrated here.

Step 2062, determining a second answer sentence corresponding to the inquiry sentence according to the keyword of the inquiry sentence.

For example, the inquiry sentence is "do you have any question", the keywords "what" and "question" are obtained in step 2061, and whether there is any question can be analyzed according to the keywords, and the second answer sentence can be "doctor, what you think me has got what disease".

And step 207, when the inquiry statement belongs to other semantic categories, processing the inquiry statement by using a first machine learning algorithm to obtain a second answer statement corresponding to the inquiry statement.

The first machine learning algorithm is obtained by training by using an inquiry knowledge base, wherein the inquiry knowledge base comprises inquiry sentences and corresponding response sentences.

Wherein, a specific implementation manner of step 207 is as follows: segmenting words from the inquiry knowledge base to obtain a word set, wherein the word set can also be called as a word bag, and a vector space is formed according to the word set; determining the vector of the inquiry statement according to the vector space; matching the vectors of the inquiry sentences in the vector space by adopting a similarity algorithm; and if the matching is successful, extracting a second response sentence corresponding to the inquiry sentence.

For example, the inquiry sentence asked by the user is: "do you need to take a blood drawing check, do you have a blood fainting". Since there is no matching rule in the matching template that matches the inquiry sentence, it is determined through the above steps 201 to 202 that there is no first answer sentence corresponding to the inquiry sentence in the inquiry matching template, it is determined through the steps 204, 2051 to 2053, 2061 to 2062 that the semantic attribute category of the inquiry sentence does not belong to any one of the symptom category, the pain category and the transition semantic category, the inquiry sentence is processed through the step 207 using the first machine learning algorithm, a second answer sentence corresponding to the inquiry sentence is obtained, for example, the answer "do not have blood halo" is matched to "do not have blood halo me", and the answer "do not have blood halo" is taken as the second answer sentence corresponding to the inquiry sentence.

Specifically, a vector space may be formed according to an algorithm such as term frequency-inverse document frequency (TF-IDF). The similarity calculation method may specifically adopt algorithms such as hamming distance and euclidean distance.

And step 208, outputting the second answer sentence to the user.

For a detailed explanation of step 208, reference may be made to the embodiment shown in fig. 1, which is not described herein again.

In this embodiment, by obtaining an inquiry statement input by a user, a first answer statement corresponding to the inquiry statement is searched for in an inquiry matching template, and if the first answer statement corresponding to the inquiry statement exists in the inquiry matching template, the first answer statement is output to the user; if the answer is not found, the semantic attribute category of the inquiry statement is determined, the corresponding second answer statement is determined according to the semantic attribute category of the inquiry statement, the second answer statement is output to the user, automatic inquiry dialogue is achieved with the user, the effect of simulating the inquiry dialogue of the patient is achieved, the answer is applied to practice and evaluation of clinical medical skills, compared with a method of training real people, the training cost can be reduced, and the training period can be shortened.

Moreover, by determining the semantic attribute types of the inquiry statement and executing corresponding processing operations according to different semantic attribute types, the processing efficiency of the inquiry statement can be improved.

It should be noted that the terminal device applying the method of the embodiment of the present invention may simulate an inquiry session of patients with different diseases, and the terminal device may receive a standardized patient simulation instruction, and determine the currently activated disease according to the disease information corresponding to the standardized patient simulation instruction. Determining the pathology knowledge base based on the currently activated disease.

That is, the pathology knowledge base includes a symptom list and a pain list, and may further include symptoms and diseases corresponding to pain parts, each disease is represented by a plurality of symptoms and a plurality of pain parts, when the terminal device may simulate an inquiry dialogue of patients with different diseases, for example, diseases such as pneumonia, cold, leukemia, etc. the terminal device may determine a currently activated disease according to the simulated disease selected by the user, that is, receive a standardized patient simulation instruction, for example, the currently simulated disease is pneumonia, and then determine the pathology knowledge base in the above embodiment according to the pneumonia, where the pathology knowledge base includes symptoms and pain parts corresponding to pneumonia.

Wherein the standardized patient simulation instruction may be an instruction of a touch operation in which the user clicks the disease selection box. For example, a user graphical interface of the terminal device to which the method of the embodiment of the present invention is applied may display a disease selection box for a user to select, and determine a currently activated disease according to an instruction of a touch operation of clicking the disease selection box by the user.
