Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings.
Fig. 1 is a first system structure diagram according to an embodiment of the present invention, which includes: the information acquisition module is used for acquiring symptom information of the patient; the preprocessing module is used for carrying out standardization processing on the symptom information to obtain input information conforming to a preset format; the symptom classification module is used for carrying out symptom classification on the input information which accords with the preset format to obtain a symptom classification result; the symptom classification result comprises: normal, depression, anxiety, psychotic, substance dependence, obsessive-compulsive; the degree classification module is used for carrying out degree classification on the symptom classification result to obtain a degree classification result; the degree classification result comprises: normal, mild, moderate, severe.
The preprocessing module, the symptom classification module and the degree classification module in this embodiment are pre-trained bert (bidirectional Encoder retrieval from transformations) models. The BERT model is a natural language preprocessing model that can classify text.
In this embodiment, the information obtaining module includes: the questioning module is used for outputting questioning content corresponding to the emotion information according to the emotion information of the patient acquired by the emotion recognition module; the input module is used for the patient to input the response to the questioning content; the questioning module is also used for adjusting questioning content according to the emotion information of the patient acquired by the emotion recognition module and the response of the patient acquired by the input module. The invention adopts a virtual psychologist mode to ask questions of the patient, and the patient answers the questions of the virtual psychologist through a human-computer interaction mode. Specifically, NLP (Natural Language processing) technology and S2A (Speech To Animation) technology are combined, voice-form inquiry examination is driven through NLP, emotion recognition of a patient is carried out according To answers of the patient, inquiry content and expressions of a virtual doctor are controlled through S2A technology, an inquiry flow is optimized, and inquiry and examination with temperature are carried out by the virtual doctor.
In this embodiment, the input module includes a text input module and/or a voice input module. That is, the patient can input his or her symptoms by text input or oral mode, so that the system can obtain the symptom information.
In this embodiment, the preprocessing module includes: the word removing module is used for removing the tone words and stop words from the symptom information and acquiring first processing information; and the sentence dividing module is used for dividing sentences of the first processing information to acquire input information conforming to a preset format.
For example, the user inputs: you are good and I feel very restless recently and have a very depressed mood! It is difficult to fall asleep at night, and it is not easy to sleep and wake up early in the morning. The system firstly carries out word removing processing to remove the stop words preset by the system, such as 'hello', 'I' and the like in the text; then, the space and the non-Chinese comma in the text are replaced by the Chinese comma, and the result after replacement is as follows: recently, people feel very dysphoria and have a very depressed mood, the people have a little difficulty sleeping at night, and the people are not easy to sleep in the morning and wake up early. And finally, taking Chinese commas as separators, segmenting sentences, wherein the result after segmentation is the following 4 short sentences:
(1) recently feel very dysphoric
(2) Depressed mood
(3) It is somewhat difficult to fall asleep at night
(4) Is not easy to sleep and wake up in the morning
The 4 phrases are input information conforming to a predetermined format. The 4 phrases are input into a symptom classification module, so that the symptoms can be automatically classified, as shown in fig. 3. In the symptom classification module, the judgment method for the symptom classification result to be depression is that the input information comprises at least one item of the following items: low mood/depression, no interest in doing things, poor sleep, feeling tired/tired, poor appetite/too much eating, feeling that oneself is bad/disappointed to oneself, difficulty in concentrating attention, slow/slow reaction, suicide/oneself injury; the method for determining that the symptom classification result is anxiety includes the steps that the input information includes at least one of the following items: stress, anxiety, worry, difficulty in relaxing, restlessness, impatience, fear, pain in body parts; the method for judging whether the symptom classification result is the psychotic, wherein the input information comprises at least one of the following items: auditory hallucination and visual hallucination; the method for determining that the symptom classification result is substance dependence includes the steps of, in the input information, including at least one of: want to smoke, want to drink; the method for judging the symptom classification result is forced, wherein the input information comprises at least one item of the following items: repetitive thoughts occur and repetitive behaviors occur. The above 25 sections can comprehensively detect the current mental condition of the patient.
For the symptom classification task, as shown in fig. 3, the BERT model inserts a [ CLS ] symbol before inputting information, and uses an output vector corresponding to the symbol as a semantic representation of the whole text for text classification. It can be understood that: this symbol without explicit semantic information fuses the semantic information of each word/word in the text more "fairly" than other words/words already in the text.
After obtaining the symptom classification result, further, the severity of the corresponding symptom needs to be judged/classified, especially for patients with depression and anxiety as the symptom classification result. At this point, the system automatically throws the question and the user needs to re-enter text or speech. For example, the system throws the question: how long did this symptom of poor sleep persist? And (3) user input: perhaps one or two days. The system makes a determination of the severity of depression based on the user's input at that time. In this embodiment, the degree classification result includes: normal, mild, moderate, severe 4 grades are indicated by the numbers 0, 1, 2, 3, respectively, as shown in fig. 4. It should be noted that, in the patients who have a depression or anxiety in the symptom classification result in the previous step, the output result in the module may be normal because the degree of depression or anxiety is slight and is within the normal range of emotional fluctuation.
In this embodiment, as shown in fig. 2, the method further includes: and the emotion recognition module is used for acquiring data of the facial expression of the patient and acquiring the emotion information of the patient according to the acquired facial expression information.
Further, still include: and the diagnosis suggestion module is used for outputting diagnosis suggestions according to the degree classification result output by the degree classification module and the emotion information output by the emotion recognition module.
The emotion recognition module and the diagnosis suggestion module are arranged, so that the system can carry out multi-dimensional diagnosis on the patient to obtain more accurate diagnosis results.
According to the psychiatric assistant diagnosis system provided by the embodiment of the invention, the information acquisition module, the preprocessing module, the symptom classification module and the degree classification module are arranged, so that the symptom information of the patient can be automatically identified and preprocessed, and the classification of the diagnosis result and the judgment of the severity degree can be automatically carried out, and therefore, a doctor can be assisted to carry out efficient diagnosis. In addition, the invention also combines an emotion recognition module to acquire the current emotion information of the patient so as to carry out multi-dimensional diagnosis on the patient and acquire more accurate diagnosis results.
