In the development process of calculating social sciences，Big data types of multiple forms are constantly emerging，For example、Internet encyclopedia wikipedia, etc.。Among the many big data types，Twitter、Facebook and online news public opinion information convergence of public opinion big data，An important observation object to computing social sciences。This article tries to make a brief analysis of the main features of public opinion big data and its application scenarios in the field of social sciences。

The first important feature of public opinion big data is its words attribute。The content of the text expresses a variety of views、Attitude and position，These are attributed to a little bit，Actually it is discourse，That is a variety of social subjects，Based on its stance，Express all kinds of opinions and opinions。Therefore，Dialogue analysis should be the first important meaning of public opinion big data analysis，With the help of high -dimensional attributes of public opinion big data，Analysis of the text of the text，Show the position and perspective behind the discourse、The confrontation and game between different discourse subjects、The volume of different discourse and social impact。

The era of rise in China，Can analyze the game between Western political discourse and Chinese discourse，You can also analyze the construction logic of Western discourse，How to find the way of cracking bet365 Play online games of Western discourse。For Chinese discourse，We can analyze the international influence of Chinese discourse，How to further tell the Chinese story、Construction of Chinese discourse。

Diverse methods of discourse analysis。From a simple theme analysis、Semantic analysis to words cluster and matching analysis, etc.，With these technologies，We can do some preliminary analysis of text expression; and use the vector space model，For example, with the help of the word vector model，The context of the key features in the dialogue can be deeply excavated;，The type of dialogue can be classified，The structure of the discourse。

The second important feature of public opinion big data is its emotional attribute。Public Opinion，Emotion also。In the information of public opinion，It will always be full of rich emotional expression，This is determined by the attributes of public opinion information。On the one hand，As far as news is concerned,，Public opinion needs to "breathe with the audience、Common Destiny "。An important feature of public opinion data is empathy，Only this，The joy and sorrow expressed in public opinion information，Only to maintain resonance with the public's joy and sorrow，Public opinion can affect society，can attract audiences。Therefore，An important feature of an online news public opinion information is its emotional attribute。On the other hand，As far as social media information is concerned，The main part of the social media is that Volkswagen expresses what she thinks about directly on social media、Survival status and way of survival，In these self -expression，Also often bet365 live casino games feels it，Share or joy、or sadness、or shock、or angry emotion。

It is because of the news media information，Still social media information，It is rich in emotional expression，Therefore, the emotional calculation of public opinion big data，Become a very important task。Over the years，Emotional calculation technology in the field of natural language processing is developing rapidly。From the initial rendering liwc、WordNet and other emotional thesaurus to carry out emotional word frequency statistics，Until now develops an emotional description based on machine learning and bert models，A variety of emotional analysis technology is developing rapidly。For the content of emotional calculations,，Primary classification from the initial calculation of positive and negative emotions，can be calculated now、Angry、Ai、Le、Love、Fear、Hate and other basic emotions。With the further development of emotional calculation technology，Further calculate more specific emotions in the future，For example, envy、Jealousy、Hate, etc.。As Li Feifei said，Development of artificial intelligence，After experiencing "visual calculation"，The focus of the next development is the calculation of emotion。Calculate emotional calculation of massive non -structured text information and images，It is an important direction for the rapid development of natural language treatment，And this provides solid technical support for scientific research related to emotional calculation。

The third important feature of the big data of public opinion is its communication attribute。The audience and the main body of public Bet365 app download opinion big data are the masses，Information、Discipline or emotional dissemination，An important landscape that constitutes public opinion，And some kind of discourse or viewpoint can spread in network space or social media space，To a large extent depends on its communication attribute。Social media platform involves very rich communication phenomena，The elements of propagation not only include discourse，It also includes emotional communication and diffusion，For example, panic emotional dissemination during the epidemic。Looking at these variety of transmission phenomena，We can find，Most of the communication information is finally destroyed in the vast information ocean，But there are also some transmission elements with vitality of communication.，Forms a huge huge wave。The key problem here is，Determine the spread of some communication elements、What are the factors of spreading landscapes? For example, populist thoughts，Why do these words sweeping global network space for a while，Is it a major social thought of rewriting history? Another example，What power is manipulating information dissemination of network space? capital、Government、What kind of role is the main body of social organizations playing in it?

Methods of analyzing the characteristics of public opinion communication also diverse。You can start from the 5W model of classic communication，Description information spread process and communication effect，​​You can also start from the method of network analysis and complex network analysis，Analysis of how social networks and social Bet365 app download structures shape information spread landscape。

The fourth important feature of public opinion big data is its social attribute。Public opinion big data includes a variety of interest subjects in social life，Covering all strata in the social system，News Public Opinion Big Data description and record the lifestyle and living state of all strata and groups in social life，The participating entities of social media big data are also various。It is because of public opinion big data covering all levels of society，Contains a variety of events，Space range covers the four seas of five lakes。Based on this，We can analyze the lifestyle and survival of different social classes and groups，You can use class analysis、Analysis of interest subjects、Research methods for various traditional social sciences such as group comparative analysis，Analyze the political and social attitude of different groups，Analyze the interaction and game between all levels of society，Analyze the relationship between the country and society，Summary summarizes social operation logic and social structure logic。

The fifth important feature of public opinion big data is its global attribute。The Internet has no borders，Public opinion information is becoming more and more connected at the global level，There are also more and more social media platforms across many countries around the world，Public opinion incidents that occur on the earth are likely to affect the distant country; at the same time，More and more public opinion big data，For example, global online news public opinion big data GDELT，Gathering public opinion information of all countries in the world。

bet365 best casino games In this context，More and more public opinion big data has global characteristics，Platform providing observation data for social science to carry out "global navigation"。Because of this，For the first time in social science, you can use these databases with global characteristics，Compare research on many countries in the world，or develop global analysis and research，For example, Golder et al. Try to use Twitter's platform，Analysis of Europe、North America、African and Oceania and other regions of human emotional evolution of human emotional evolution of day and night rhythm。I think，The direction worth further analysis is，You can also from the global level，Analyze the survival and living conditions of different ethnic groups in different cultural backgrounds，Analyze the values ​​and cultural concepts of the public in different corners of the earth，Carry out large -scale cross -cultural comparative research。

Under the background of public opinion big data monitoring，Social science research can use these global empirical data，Empirical analysis of many countries and society in the world，Having overcome the limitations of the "local knowledge" of past social science research，Carry out an empirical analysis that really has global comparative significance。Therefore，Incorporate global vision into the empirical analysis of social sciences，Through comparison of the evolution characteristics of multiple social systems，Or incorporate different society in the world into the same analysis system，Perhaps it can provide important support for future social science research expansion research Bet365 app download and opening up new research fields。
