In the development process of computational bet365 code science，Various forms of big data types continue to emerge，For example, book text big data Google Books、Network Encyclopedia Big Data Wikipedia, etc.。Among many big data types，With Twitter、Public opinion big data gathered from Facebook and online news and public opinion information，Important observation objects constituting computational bet365 code science。This article attempts to briefly analyze the main characteristics of public opinion big data and its application scenarios in the field of bet365 code sciences。

The first important feature of public opinion big data is its discourse attribute。The content of the text expresses a variety of views、Attitude and stance，These boil down to one point，actually words，That is, various bet365 code subjects，Based on its position，Express a variety of opinions and views。Therefore，Discourse analysis should be the first important meaning of big data analysis of public opinion，Using the high-dimensional attributes of public opinion big data，Discourse analysis of text，Present the position and viewpoint behind the words、Confrontations and games between different discourse subjects、The volume and bet365 code impact of different words, etc.。

In the era of China’s rise，Can analyze the game between Western political bet365 code and Chinese bet365 code，You can also analyze the construction logic of Western bet365 code，And how to find a way to crack the Western bet365 code。For Chinese bet365 code，We can analyze the international influence of Chinese bet365 code，And how to further tell China’s story、Constructing Chinese bet365 code。

There are various methods of discourse bet365 code。From a simple theme bet365 code、Semantic bet365 code to word cluster and collocation bet365 code, etc.，With the help of these technologies，We can do some preliminary bet365 code of text expression；With the help of vector space model，For example, with the help of word vector model，Can dig deeper into the context in which key features in the discourse are embedded；With the help of sentence vector space model，You can classify the types of utterances，Present the structure of discourse。

The second important feature of public opinion big data is its emotional attribute。Public opinion maker，Emotions too。Public opinion information in progress，Always filled with rich emotional expressions，This is determined by the properties of public opinion information。On the one hand，In terms of news and public opinion，Public opinion needs to “breathe the same breath” as the audience、Shared fate”。An important feature of public opinion data is empathy，Only this way，The joy, anger, sorrow and joy expressed by public opinion information，Only in order to maintain resonance with the emotions of the masses，Only public opinion can influence society，In order to attract the audience。Therefore，An important feature of online news and public opinion information is its emotional attribute。On the other hand，In terms of bet365 code media information，The main part of bet365 code media is that the public directly expresses their thoughts and ideas on bet365 code media、Survival status and survival style，In these self-expressions，It often comes from feelings，Sharing the yes or joy、or sadness、or shocked、or angry emotion。

It is precisely because whether it is news media information，Or bet365 code media information，All are rich in emotional expression，So perform emotional calculation on public opinion big data，It becomes a very important task。Over the years，The rapid development of affective computing technology in the field of natural language processing。With the help of LIWC from the beginning、WordNet and other emotional lexicon databases carry out emotional word frequency statistics，Up to now, we have developed detailed descriptions of emotions based on machine learning and BERT models，Various sentiment analysis technologies are developing rapidly。In terms of the content of affective computing，From the initial calculation of the primary classification of positive and negative sentiment，Now you can calculate happiness、anger、Sorrow、乐、Love、fear、Basic emotions such as hatred。With the further development of affective computing technology，More specific emotions will be calculated in the future，For example, envy、jealousy、Hate and so on are all promising。As Li Feifei said，The development of artificial intelligence，After experiencing "visual computing"，The next development focus is affective computing。Perform emotional computing on massive amounts of unstructured text information and images，It is an important direction for the rapid development of natural language processing，This provides solid technical support for scientific research related to affective computing。

The third important feature of public opinion big data is its communication attribute。The audience and production subject of public opinion big data are the public，Message、The spread of words or emotions，An important landscape that constitutes public opinion，And whether a certain discourse or opinion can spread in cyberspace or bet365 code media space，Much depends on its propagation properties。bet365 code media platforms involve very rich communication phenomena，The elements of communication include more than just words，Also includes the spread and diffusion of emotions，For example, the spread of panic during the epidemic。Looking at these various communication phenomena，We can find out，The vast majority of disseminated information eventually perishes in the vast ocean of information，But there are also some communication elements with vitality that eventually spread，Formation of huge waves。The key issue here is，Determine the communication power of some communication elements、What are the factors of communication landscape？For example, populist trends，Why these words swept the global cyberspace for a while，Constitutes a major bet365 code trend of thought that rewrites history？Another example，What forces control the dissemination of information in cyberspace？Capital、Government、What role do bet365 code organizations and other stakeholders play?？

There are also various methods to analyze the characteristics of public opinion communication。You can start from the 5W model of classic communication，Describe the information dissemination process and dissemination effect，You can also start from the methods of network analysis and complex network analysis，Analyze how bet365 code networks and bet365 code structures shape the landscape of information dissemination。

The fourth important feature of public opinion big data is its bet365 code attribute。Public opinion big data includes various stakeholders in bet365 code life，Covering all levels of the bet365 code system，News and public opinion big data describes and records the lifestyle and living conditions of various classes and groups in bet365 code life，There are also various participants in bet365 code media big data。It is precisely because public opinion big data covers all levels of society，Contains multiple events，The space covers all corners of the country。Based on this，We can analyze the lifestyle and living conditions of different bet365 code classes and groups，Can use hierarchy analysis、Stakeholder Analysis、Group comparative analysis and other traditional bet365 code science research methods，Analyze the political and bet365 code attitudes of different groups，Analyze the interactions and games between various bet365 code classes，Analysis of the relationship model between the state and society，Summary and induction of bet365 code operating logic and bet365 code structural logic。

The fifth important feature of public opinion big data is its global nature。Network without borders，Public opinion information is increasingly interconnected at the global level，There are also more and more bet365 code media platforms spanning many countries around the world，A public opinion incident somewhere on the earth is very likely to spread to distant countries；At the same time，More and more public opinion big data，For example, global online news and public opinion big data GDELT，Gathers public opinion information from all countries in the world。

Against this background，More and more public opinion big data has global characteristics，Provides a platform for observation data for bet365 code science to carry out "global voyage"。Exactly because of this，For the first time, the bet365 code sciences can draw on these databases with global characteristics，Comparative study of many countries in the world，Or carry out global scale analysis and research，For example, Golder and others are trying to use the Twitter platform，Analyzing Europe、North America、Global universality of circadian rhythms in human emotional evolution in multiple regions, including Africa and Oceania。The author thinks，The direction worthy of further in-depth analysis is，Also from the global level，Analysis of the survival styles and living conditions of different ethnic groups under different cultural backgrounds，Analyze the values ​​and cultural concepts of people in different corners of the earth，Carry out large-scale cross-cultural comparative research。

In the context of global public opinion big data monitoring，bet365 code science research can make use of these global empirical data，Carry out empirical analysis on many countries and societies around the world，Overcoming the limitations of “local knowledge” in bet365 code science research in the past，Carry out empirical analysis with truly global comparative significance。Therefore，Incorporating a global perspective into empirical analysis in the bet365 code sciences，By comparing the evolutionary characteristics of multiple bet365 code systems，Or bring different societies around the world into the same analytical system，Perhaps it can provide important support for future bet365 code science research to expand research horizons and open up new research fields。
