Abstract ：
［ Purpose / significance ］ Scientific analysis of the energy transmission process of network public opinion and effective control of the development direction of public opinion is an important part of network public opinion management of major medical injury events , For relevant media platforms 、 Medical institutions and the government provide reference for public opinion management of medical events .［ Method / The process ］ From emotional diffusion and social communication Two dimensional perspective set out , Build a public opinion energy transmission model and propose a calculation method . selection “ Wei Zexi incident ” As the empirical research object , Take Sina Weibo as the data source, and use web crawler software to obtain public opinion text information and forwarding behavior information , With the help of ROST Emotion Analysis Tool Complete text emotion analysis , By simulating Single Weibo energy curve and Energy field The change characteristics of the energy curve in different periods are obtained by analyzing the total energy change curve .［ result / Conclusion ］ Results show , There is public opinion about medical injury events 4 Two transmission characteristics and two emotional polarities ; The public opinion energy field based on emotional diffusion and social communication can truly reflect the development of events and the emotional bias of public opinion ; The public opinion energy field of medical injury events has significant Peak energy , But it will eventually be consumed over time .

（1） The network public opinion of major medical injury events is due to its The incentives are complex 、 The process of viewpoint alienation is complex 、 Stakeholders are complex and events are difficult to calm And other characteristics have aroused widespread concern from all walks of life , It has quickly become a hot topic in domestic academic circles ［2］.
（2） After more than ten years of research , At this stage, the research on network public opinion of major medical injury events in China has begun to take shape and formed a relatively complete knowledge system , The research content mainly focuses on the following three aspects : a. Research on public opinion regulation ;b. Analysis of public opinion characteristics and Strategy Research ;c. Research on the evolution of public opinion based on case analysis .
（3） After the content analysis of the existing literature, it is found that , The network public opinion of major medical injury events can also be further studied from the following two aspects : a. Quantitative research on the energy diffusion of public opinion ;b. Consider the integration of emotional diffusion and social communication .—— This turning point is well written , It not only summarizes the previous research results , It also points out the author's innovation in this research direction ！
（4） therefore , Based on the above analysis, this study chose major medical injury events as the research theme , From the perspective of emotional diffusion and social communication , Based on the analysis of the law of public opinion transmission, the characteristics of emotional attributes and forwarding behavior are introduced , Explore the energy transmission characteristics of public opinion , And then form integrity 、 Regular cognition and Discussion on medical institutions 、 The government and the media respond to emergencies in a timely manner 、 It is of positive significance to formulate scientific public relations management strategies .—— Point out the significance of research

1 Model construction and algorithm design
1．1 Theoretical basis
（1） Information energy research emphasizes the importance of information ecosystem Dynamic and developmental , Think that information contains energy , The energy value represents the strength of information vitality in the process of information transmission , Metrics include the amount of information 、 The scope of information transmission and the degree of information attenuation ［9］.
（2） Unlike other public opinion events , People's in medical events **“ A sense of weakness ” Strengthened , In the face of major medical public opinion events , It is easier to anonymize through the Internet 、 Low cost venting ［13］, Social and emotional elements are very prominent in the process of public opinion dissemination of such events ;
（3） According to the energy limitation theory of continuous cognition , The information asymmetry under the medical system and the dilution effect of the continuous input of new public opinion information Next , Public awareness of the medical public opinion event gradually declines [ 14］, Subsequently, the public opinion energy of the event is also gradually lost .
（4） Commonly used in the study of public opinion diffusion Chamber model It is believed that the individual state in the process of public opinion mainly includes non informed S ( Susceptible) 、 Knowing E( Exposed) And spread I( Infective)［15］.
（5） The energy contained in the public opinion text can flow through the social relationship network between users , Individual state also changes from uninformed state to informed state or communication state , Public opinion energy began to be Activate **.

1．2 Public opinion energy transmission model and calculation method

2 Empirical research
2．1 Data sources and research methods
（1） This study selects 2016 year 5 Major medical injury events broke out in August “ Wei Zexi incident ” As the empirical research object , Here's why : a． It involves many objects and has great influence , The most famous information search service platform in China 、 Armed Police Hospital 、 The largest private medical service system in China “ Putian department ” One after another involved ; b． The treatment plan of the disease involved is quite controversial , The patient is in a typical Information weakness status ;c． “ Wei Zexi incident ” The event has attracted wide attention , There is a network The climax of public opinion And certain Topic reversal . Based on this , This paper holds that , In addition to the general characteristics of public opinion events ,“ Wei Xi Xi ” Event view High responsiveness ［18］、 The information gap between doctors and patients is large ［19］、 There is Viewpoint alienation ［20］, It has the typical characteristics of major medical injury public opinion events , It plays a certain reference role for other similar types of medical injury public opinion research .

2．2 Sentiment analysis
Professional software that analyzes the emotional value of Weibo text ROST Emotion Analysis Tool Analyze and calculate the emotional value of text . The software has built-in 1 There are more than ten thousand emotional words commonly used on the Internet , The range of emotional value of word text is ［－20,20］, Express positive emotions respectively ( The value is greater than zero ) 、 Neutral emotions ( Value is zero ) And negative emotions ( The value is less than zero ) . After processing the text, the emotional words are scored , And the total score of the text is calculated , Can achieve 82.7% Accuracy of emotional polarity and 79.7% Emotional intensity accuracy .

2．3 Single energy field analysis
a． Function parameter analysis

b． Energy peak analysis
（1） Whether the emotional content of Weibo text is positive or negative , The energy accumulation brought by Weibo forwarding is roughly the same , There are one or more peaks , And the peak duration is short . Besides , The peak number of different microblogs is different , Most of them have only one energy peak and the residence time is short, generally 6 ～ 8 Hour or so . But in some special cases , For example, if Weibo is forwarded by an authoritative account with a large number of fans, it can often cause a secondary forwarding peak , And the residence time near the peak is longer .

c． Energy trend analysis
Most popular microblogs exist Explosive accumulation of energy 、 Fast energy consumption and slow energy consumption Three stages . however , For Weibo with multiple forwarding peaks , If the time interval between the secondary energy peak and the primary energy peak can be controlled within a certain range , It is possible to form a stable energy peak period .

2．4 Overall energy field analysis
(1) But on the whole, positive energy is significantly higher than negative energy , It shows that after many medical public opinion events in the early stage, the public and all parties involved have gradually become rational and restrained , Public opinion has been well controlled in a specific period of time , A lot of analysis is objective 、 Advocate social justice 、 The public opinion information containing positive content and emotions that actively build a harmonious doctor-patient relationship has been effectively disseminated and diffused .—— Domestic journal papers must lead the topic to positive energy .
