Scientometrics Analysis Method for Society 5.0

It includes the systematic examination and mapping of the literature studies written for Society 5.0 using the CiteSpace application, with the scientometrics analysis method, the identication of the network of relations, and the discovery and intellectual analysis of their bibliographic contents. 151 bibliographic records from the Scopus database were analyzed between January 2017 and May 2021. Qualitative analysis of the obtained quantitative data based on the interpretative paradigm was made. Analysis of countries, intellectual analysis, keywords; burst point and cluster analyzes were performed. The case is gaining increasing importance in the multi-disciplinary eld. Since the phenomenon of Society 5.0 is still current and concerns the future period, it is seen that it is a developing eld in the literature. In the literature about this case; The fact that scientometrics studies and CiteSpace analysis have never been done has increased the originality of the study. It will be important for super-smart society goals to specialize in the elds studied and to increase the working tendencies in the elds that are lacking (sociology, psychology, gerentology, etc. social sciences).


Introduction
When the history of the world is examined, it has been seen that societies follow a cumulative course in conjuncture with social and economic processes. Although the world wars experienced from time to time have reduced the speed of these situations, the stages of social and industrial revolution have developed continuously. There has been a transition from hunting-gathering to an agricultural society and from there to an industrial society. Digitalization, which is the necessity of the new world order, and the infusion of the internet into the way of life of societies have been indicators of a new phase. Data will be recorded and processed electronically through digitalization (Reker and Böhm, 2013). In this way, instant use of the information obtained in the new world order will be realized.
The rapid development of information and communication technology (ICT) will bring major changes to society and industry. Digital transformation will create new material and moral values and will become the pillar of industrial policy in many countries (Fukuyama, 2018: 47). For this reason, to read the concept well in terms of the development of the systematic sustainability of the future world societies, to identify the priority countries, to examine and adapt their policies; It will be important to identify many references, networks and keywords used with Society 5.0, to make inferences about the future, to examine the categories that deal with the concept, to identify interdisciplinary situations and to propose applications for all these.
In the study, scientometrics analysis method was used. Keywords, abstracts and titles were searched from the Scopus database with the titles "Society 5.0" and "Super-smart Society". In the light of the data obtained, systematically; Inferences were made from the literature trends, countries and keywords. Work is a very current phenomenon that concerns future societies. The qualitative de nition of the quantitative data included in the study is made. The fact that no scientometrics study or CiteSpace analysis application was used for the Society 5.0 phenomenon increases the originality of the study.
2. Super-smart Society 5.0 Industry 4.0 has emerged in Germany and The Country has taken its place at the beginning of the most important countries that have adapted to this phenomenon, along with the USA, China, Korea and Japan.
The mentioned countries have been the countries with the most industrial robot production as of the period when robotic technologies were prioritized in the industry (Gemma et al., 2017). It has been seen that Japan is at the center of the Society 5.0 phenomenon, which ultimately concerns the present and the future period. Japan rstly implemented Industry 4.0 in its own country and laid the groundwork for Society 5.0.
What is Society 5.0? The concept of Society 5.0, the new world order, is the implementation of Japanese government policy that emerged in 2017. Under the name of "Future Investment Strategy", it is thought that the policy will be a solution to economic growth with the gains to be achieved in the medium-long term (Waldenberger, 2018). Society 5.0 is a phenomenon that has provided its development with the foundations of this phenomenon and gained new gains before the exit from the Industry 4.0 phenomenon has been made in the world history. The concept of Society 5.0 is the national policy initiative that Japan aims to implement in 2015 (Keidanren, 2016). Then, Japan's Prime Minister Shinzo Abe, who participated in the IT fair CeBIT 2017 summit, introduced it under the name Society 5.0. He stated that technology-friendly social life should be adopted and aimed that technology would help individuals in social life.
Japan faces a declining workforce and rising social security costs. The current workforce of more than 77 million people is expected to decrease to approximately 70%, 53 million people, by 2050. On the other hand, the cost of social security will rise from 120 trillion yen in scal 2015 to 150 trillion yen in scal year 2025 due to the aging of the population (Fukuyama, 2018: 47). The di culties faced by Japan, such as declining birth rates, declining population, increasing elderly population and inability to respond to the problems of infrastructure, are the problems that many other countries in the world will eventually face.
Keidanren, Japan Business Federation is well aligned to proactively ful ll the United Nations Sustainable Development Goals to end poverty, protect the planet and ensure prosperity for all through the creation of Society 5.0 (Shiroishi et al., 2018: 91). The aim of the case is to unite the physical life and the virtual world and to help individuals improve their quality of life by eliminating economic development and social problems.
As seen in the concept of Society 5.0, the main actor is not technology (tool), but human. It has been stated that digital technologies and data should be used to create a society where people lead different lifestyles and follow happiness in their own way (Keidanren, 2018:1). Although Industry 4.0 affects all segments of society, its main purpose is; digitization in industrial life and working life, and the effects have spread to all segments. Society 5.0, on the other hand, started out with the aim of developments that concern both working life and all segments of the society. Society 5.0 undertakes to meet the needs of individuals instantly, to have a high quality of life, and to live a happy and prosperous social life regardless of age, gender, ethnicity (Harayama, 2017).
The most talked about topics about the phenomenon of Society 5.0; cyber-physical systems, cloud technology, internet of things (very important in terms of combining the real world and the virtual world), arti cial intelligence concepts have been adapted with new systems that will meet human needs. It has been observed that individual-centered production structures have emerged due to the adaptation and exible structuring of humans and machines in the operation process, effective use of communication and transportation (Foresti et al., 2019).
It has been seen that human and machine are integrated in working life, communicating and using arti cial intelligence in a synchronized way, production mechanisms and e ciency are improved through the Internet (Capgemini-Prognos, 2018). According to this strategy, the key to achieving medium and longterm growth is to integrate the rapidly occurring innovations of the 4th Industrial Revolution (eg IoT, big data, arti cial intelligence, robotics, sharing economy, etc.) into every industry and social life to meet various societal challenges. The solution is to realize Society 5.0 (Fukuyama, 2018: 48).
As can be seen, the concept has assumed a multidimensional form in every sense. Since the phenomenon is still new, it is seen that the outputs and effects will be obtained as of the next period. Together with the systematic handling of the case using the sciometric analysis method, the maps of the concept of Society 5.0 in the process will be revealed and will inform us about the future study topics.

Scientometrics
Scientometric, V. V. Nalimov was literated in 1960 by the term "scientometrics" and used to identify science studies that revealed growth, structure, relations network and productivity (Hood and Wilson, 2001:291). It has intersecting networks of scientometrics, bibliometrics, informatics and information technologies. Refers to relationship networks related to the discovery of dynamic structures of data in the literature. Science and technology are used to examine the intersecting aspects of literature. Scientometrics and bibliometry are di cult concepts to distinguish. But the focus of bibliometry, despite many broad-scale recognition, has always been the scienti c literature itself, whereas science and technology are more than just a literary output for scientists to measure and analyze; for example, the applications of researchers, socio-organizational structures, research and development management, the role of science and technology in the national economy, government policies for science and technology, etc. Statuses (Wilson, 2001). Nagpaul, et al (1999) categorized trends in scienti c studies; made implications for science and technology policies, including the structure and dynamics of science, including internationally collaborative cooperation between regional aspects of science to the individual level, within the scope of methodology used in science and science.
Evaluation of the phenomenon of Society 5.0 within the scope of scientometrics in the research, the fact that both itself and the method of obtaining literature data have technological and scienti c commonalities; It will assist in obtaining inferences and policy recommendations for the scienti c literature and society.

Research Philosophy And Method
The study is evaluated in the philosophy of Qualitative Research Methods based on Post-Modern/Anti-Positivist science (Ritchie et al., 2013: 15). Exceptions break the rule, the issue of data reality is at the forefront rather than the term mean true. The universal is not correct, the right place, time, depends on context (Holloway and Wheeler: 2010). Our work is suitable for this structure. Because the average speci c to Society 5.0 is not accurate and over time the scope of the scientometrics analysis is expanding. Therefore, because it is constantly updating and expanding the concept, changes will exist in the context of time, context, or even in the context of where it is being worked. In this philosophy, the facts of society and the individual are being explored. The main philosophy of our work is idealism. The subparadigm on which Idealism is based is interpretive (Guba and Lincoln, 2001;Collins, 2010). There is a deductive, interpretive (hermeneutics) paradigm in which qualitative research methods are used in the study. Interpretive paradigm, the social world; It is an approach that tries to understand and explain the minds of individuals in society. Real knowledge is based on individuals' perspectives and thoughts. (Günbayı, 2019;Deetz, 1996;Reeves and Hedberg, 2003: 32). The themes that are revealed algorithmically in the program will be analyzed with the theme analysis method in accordance with the interpretive paradigm. According to TerreBlanche and Durrheim (1999), the research process has three main dimensions: ontology, epistemology, and methodology, and for them, a research paradigm is an allencompassing system of interrelated practice and thought that de nes the nature of research across these three dimensions. These Information Theory Criteria will play an important role in forming the framework of the study.
Firstly, when looking at the Ontological Criterion; What is the source of the information? Where is it? Idealism, which deals with the subjectivist approach, and its interpretative paradigm and nominalist perspective (Günbayı and Sorm, 2018;Collins, 2010) will lead us to the discovery of the data obtained.
The examined reality is in the minds of individuals (subjectivist approach). In the subjectivist approach, the source of knowledge in social life; it is the person himself, his mind, view and point of view (Burrell and Morgan, 1979). The data obtained from the Scopus search channel constitutes the reality of the people doing the study. The starting point in social sciences is human and in our study, scientometric analysis of research based on the authenticity of the authors is carried out. Based on the Human Nature Problem, the subjectivist approach, it seems possible that human beings are naturally intelligent beings, that they act with their own mind and will, and that it is necessary to reveal the correct information with their own will. When analyzed according to the Epistemological Criterion, the ways in which information is collected will lead us to true and true information. It takes us to the subjectivist approach when we take the person as the basis and deal with the truth of the people. For this reason, the facts in the works of the authors contain their perspectives and minds and help us to interpret them as scientometric analysis. Finally, when the Methodology of the study is examined, the question of how the method will be is in the foreground. In the approach, information is accessed ideographically (Günbayı and Sorm, 2018). Is the source the human mind? In our study, the source is the human mind within the framework of the subjectivist approach, the facts of the authors who conduct research on the subject.
Axiology of research; it presents us what is important, valuable and the limits of the study. The study has the distinction of being the rst research article in the international literature on the phenomenon of Society 5.0, made with the sciometric method. In addition, for the rst time, the CiteSpace application was used to analyze the Society 5.0 phenomenon. Therefore, it is a work with high originality. However, there are certain limits. Scopus, one of the most important and effective search channels, is used in the study. But search channels like WOS and Google Scholar will also affect coverage size. Expansion can be achieved by using these scopes in future studies.

The Problem of Research
The scientometrics method was used to explore the outputs of publications, research trends, publication patterns, and data for the Society 5.0 phenomenon, and to make policies. The interpretative paradigm was used on the data obtained to analyze, explore, interpret and make recommendations on the publication trends of scienti c literature using scientometrics. countries, keywords and collaborations contributing to the international literature were quantitatively revealed and interpreted qualitatively. Research problems have been created for this purpose; How do literary trends for the case of Society 5.0 follow the course?
How are the productivity and relationship networks (such as cooperation networks, centrality and frequency) of countries regarding the phenomenon of Society 5.0?
How do the references dealing with the phenomenon of Society 5.0 contribute to the eld?
For the keywords studied within the scope of Society 5.0; What are the implications of collaborations, burst points and cluster analysis? How do representative documents contribute to the eld? What are the implications for future directions?

Database Selection
Research evaluation applications are becoming increasingly important today as the main providers of universally used bibliometric data. Since the reliability of these channels depends on the data source, the most appropriate database should be selected. Scopus is one of the two most important main bibliographic databases (Pranckutė, 2021: 1).
The database of the research was chosen as Scopus. This database was chosen because Scopus is quite comprehensive in the eld of social sciences (Jabali et al., 2020: 4-5). For citation analysis, Scopus offers about 20% more coverage than Web of Science, while Google Scholar provides inconsistent accuracy results (Falagas et al., 2008: 338). Scopus is currently the world's largest research abstract and citation database, containing 24,600 journals from 5000 publishers (Elsevier, 2020). Scopus is the world's largest peer-reviewed scienti c literature data source, with 75 million indexed items. In addition, Scopus updates the data daily and 32% of the total content indexed in Scopus belongs to the social sciences literature (Rashid, 2021: 3). Identify emerging trends What are the latest research areas? Who are the leading experts? Do you uncover the full scope of cutting-edge research? It fosters innovation through multidisciplinary research and reviewing, analyzing and sharing insights while seeking answers to their questions. The use of the Scopus database in our study is an important factor in terms of scope and compatibility with technology.

Search Query
In order to obtain bibliographic data about the phenomenon of Society 5.0 and to make scienometric inferences, a search interface was run in the type of search query and search eld. In the Search tab: "Article Title, Abstract and Keyword" query was made. search terms; TITLE-ABS-KEY ("Society 5.0") OR ("Super-Smart Society"). The two phrases have been chosen because they are compatible and related to each other and because they are the most effective terms within the scope of the subject. There is no time limit on the search tab. The date of data collection from the system is 30.05.2021.

Research Data
165 studies for the term "Society 5.0" and 10 studies for the term "Super-Smart Society" were obtained in the search on the database. In total, 175 studies were examined in detail and 2 studies were determined not to be subject-speci c and excluded. No temporal restrictions were made (from 2017-2021 End of May), no language or geo-ltering was applied. Data; conference paper (N = 71), article (N = 67), book chapter (N = 17), conference review (N = 5), review/review (N = 5), book (N = 3), editorial (N = 3), grade (N = 1) and short questionnaire (N = 1).

Data Analysis Method
The bibliographic data of 173 studies were obtained and the 5.7.R5 version of the CiteSpace application was used to perform the sciometry analysis method. The application was chosen because of its high quality in simplifying, transforming and analyzing our analysis process, innovative mapping of network of relationships, and being the rst research application to be written in this eld. This app combines many types of data as well as countries, keywords, references etc. In this context, it will help in mapping studies (Chen, 2006). In addition, clustering analyzes through the application help us to make inferences for the future and develop suggestions by obtaining cooperation networks.
Before starting to analyze the data, the quotation marks were deleted with the Notepad + + program to make the data suitable for analysis. Then in the application "ris." format has been converted. The analysis was continued with 172 studies that could not be converted to 1 study and 6456/6088 (94.0%) valid references. 95.0% is a very good success rate, considering all the irregularities of the cited references (Chen, 2014: 66). In our study, it has been seen that it provides a good conversion rate as it is very close to 95%. The last operation, which is the deletion of duplicate documents, was carried out before being put into the analysis. On the application, 21 duplicate documents were excluded from the scope of analysis, and nally, 151 documents were included in the scope of analysis.

De nitions of Statistical Methods
In the application software, node link graphs, co-citation network analysis, detection of collaboration, centrality, citation burst points, cluster analysis, modularity, silhouette value etc. There are stages of analysis such as (Chen, 2004). CiteSpace, nodes re ect items such as keywords, countries, authors, etc.
Node sizes indicate the number and density of studies. The colors on the nodes represent different time periods. The lines between nodes; It re ects cooperation and relationship, and the colors represent time.
Centrality is an important species in the eld. Centrality represents the degree of importance. The center spacing of a node is similar to the constantly used toll booth, the center spacing of the most used toll booth will be high, and the center spacing of the less used toll booth will be low (Chen, 2016: 30). The fact that the center edge of the node is purple shows the importance, power and effectiveness of the centrality between them. The key node is the part with intermediate centrality ≥ 0.1. The bursting point is an important indicator for determining the trend of the research focus. Redness of circles and lines in the graph; it shows the time period of quote bursts and trend, trend is detected.
Cluster analysis reveals themes determined through the application's algorithm. The modularity of the clustered partner networks and their average silhouette scores represent the algorithm features of the cluster analysis. Modularity is applied in order not to focus on individual nodes and local details (so that the overall schema is not overlooked) and to divide the panoramic network into separate node groups within the visual analytic process for this. This kind of splitting can be done with quite a variety of clustering algorithms. The modularity of the network measures the extent to which it can be decomposed into multiple components or modules within the network. Modularity value (Q); It is convincing that it is between 0,30 < Q < 1.00 (Chen, 2016: 32). A value close to 1 indicates that it is fairly well partitioned. The silhouette value (S) of the cluster measures the quality of the clustering. It ranges from − 1 < S < 1, value of 1 represents perfect resolution.

Literature Trend
The year 2017 represents the starting point for studies on the Society 5.0 phenomenon. Between 2017-2021, it has been observed that the studies on this subject in the literature have grown signi cantly. From 2017 (n = 8) to the end of 2020 (n = 63), it was observed that the number of studies on the subject increased approximately eight times./p> As can be seen in the gure, there is an acceleration in an increasing structure. As of May 2021 (n = 33), it was seen that more than half of the studies published in 2020 were published. If the momentum continues in this way, the end of 2021 will be the year in which the largest number of works will emerge.
In addition, when the number of citations is examined, it is seen that it follows a similar course. The number of citations in 2020 (155) is approximately six times more than the number of citations in 2017 (26). As of the end of May 2021, it was determined that the acceleration of the number of citations (100) increased rapidly compared to the previous year. As can be seen, it has been observed that the number of citations in the literature has increased rapidly over the past years. As a result, these two situations show us that the trends in the literature on this subject have increased rapidly and the subject has attracted attention over the years.

Productivity and Collaboration Analysis of Countries
The CiteSpace application revealed 61 nodes and 43 links to analyze and map the countries. There are publications on the subject of Society 5.0 in 61 different countries. However, with the emergence of 43 connections, it has been observed that there is limited cooperation between countries on this issue, that countries either establish connections with studies within themselves or cooperation is made between studies among major countries (Fig. 2). At this point, the increase in the cooperation of countries; It will help each country's conditions, contexts, and countries to produce unique outputs. With the increase in collaborations, the authors can make the phenomenon adaptable to their own country within the framework of certain references.
The top ten countries in terms of number of publications and degree of centrality are listed in Table 1.
The country with the most publications was Japan (42), which revealed the phenomenon of Society 5.0.
Indonesia (29) and the United States (12) came rst among the countries that broadcast the most. The degree of centralization on the basis of countries has remained low due to the limited number of studies and the fact that it only covers a period of four years. The most important country in terms of centrality is the United States of America (0.06), followed by Poland (0.03), Japan (0.02) and Russia (0.02). It was seen that Japan came to the fore on the basis of publication and the USA and Japan on the basis of centrality. It is normal for Japan to have such a high number of publications, since it is the country that reveals the source of the phenomenon (Keidanren, 2016). However, it may seem surprising that the number of publications in the country of Indonesia is so high, but it is not. Because Indonesia is one of the countries that applies the phenomenon of Industry 4.0 to all areas of social life (Natalia & Ellitan, 2019;Hamdanunsera, 2018). The penetration of Industry 4.0 into every aspect of society has led to the phenomenon of Society 5.0. The ve industries (textile, automotive, electronics, chemicals, food and beverages), which are considered as focal points against Industry 4.0 and Society 5.0, are very important in terms of competitiveness and are expected to enter the top ten countries in the world economy in 2030 (Ellitan, 2020;7-8). ). In addition, according to the Google Trends data of 2021, the countries with the most searches for the word Society 5.0 are respectively (if we consider that the least popularity value is 0, the most popular value is 100); Japan (100), Indonesia (41), Malaysia (18), USA (2), Germany (1). Thus, the relationship between Indonesia and Society 5.0 can be understood. On the other hand, it is seen that the USA started the studies as late as two years but formed the intersection point as the country with the highest level of importance.
It is seen through the nodes on the map that Japan has the oldest and newest works. Although it is natural that the studies in the USA are not as old as Japan, it is seen that the number of years is not to be underestimated. At this point, the USA is one of the countries with a high potential to continue its work in the future, as it carries out many and centralized studies in a short time.
In Fig. 2, it is seen that the cooperation between the USA and Indonesia countries has followed a comprehensive course. It has been seen that the cooperation between the USA-Slovakia, Japan-Indonesia, Russia-Poland is extensive. It has been observed that Portugal's cooperation network with other countries is effective. The other strongest cooperations were seen to be Russia-Poland, USA-Indonesia, Japan-Indonesia, USA-Slovakia. (All of them have 1.0 value) Since the number of countries is higher than the number of connections, it is normal for the value of inter-country connection to be so high. In the future, it will inevitably be seen that there will be decreases in the value of the connection with the increase in the number of cooperation.

Reference Analysis
Analysis of references is used to identify the intellectual structure and collaborations of the literature. Rather than the cited authors, reference analysis was used because of the innovative nature of the case and the comprehension of the content of the studies. While determining the nal decision regarding this situation, necessary information was obtained by the founder of the CiteSpace application and an expert academician.
Considering the reference analysis of the studies studied for the case, Top N was included in the analysis as 100% (all references), unlike other parameters. Unlike other analysis titles, when Top N% was included in the analysis at a normal rate, it could not reveal the desired effect, even if it was similar to the analysis obtained in total. Including all studies in the system will be more important and effective in making discoveries and comments on references. It is seen that 5651 nodes and 17088 connections have emerged. The result was quite comprehensive as all of the studies were included in the analysis. Figure 3 shows the relationship networks map. Table 3 shows the number of nodes and connections that change from year to year, Table 4 shows the references with a centrality level of 0.01 and above that are jointly cited in order of Centrality. When the table is examined, it is seen that the nodes increase rapidly from year to year. Parallel to this situation, it was observed that the connections increased rapidly. In May 2021, it was seen that there were much higher nodes and connections than the result of the previous year when we divide it by average months. Therefore, when we come to 2021, it has been seen that there are quite good node and connection numbers according to the current studies, and if the increase rate continues in this way, it is predicted that the phenomenon will reach the highest number of references and connections by the end of 2021. This means a rapid expansion of the subject's scope.When the network map is examined, it is seen that the number of references made to authors such as Y.Shiroishi, M. Fukuyama, B. Salgues, K.
Fukuda is ahead of the others. These authors are the main reference sources for the Society 5.0 phenomenon. The level of centralization was considered to be important in the reference analysis in Table 4. Since it determines the studies with the highest level of importance, the importance of the studies that are taken as a common reference will be determined. However, the level of centralization remains low, as the case is still new and there is not much literature accumulation.  (2018); He stated that the phenomenon of Society 5.0 emerged with the rapid development of technologies spreading globally, and he criticized the dramatic social changes that came with it. As can be seen, the cited references are important basic reference sources for the Society 5.0 studies. Because it provides general and basic information about the phenomenon and forms the basis for the studies to be included in the literature. It has been observed that the studies generally make general statements, policies and promotions in the technological and economic eld for the phenomenon of Society 5.0. Currently, it is usual for general statements to be quoted in new works. As the subject becomes more speci c and the elds become more speci c, general information can evolve with different concepts.

Analysis of Keywords and Future Research Guidelines
When the common keyword analyzes in the studies are examined; It was seen that 195 nodes and 633 connections emerged. Of the 195 clusters, 70 (highest) were in 2020 and 52 in May 2021. It has been seen that there is an increasing scope as the years go by, the subject is quite up-to-date and 2021 has the potential to host the most studies on this subject. In Fig. 5., the year-based relationship network map of the keywords is revealed. In Table 5 keywords such as digital transformation, sustainability, critical thinking, innovative learning, arti cial intelligence technology, and blockchain were predominantly used. As you can see, keywords are terms that differ from year to year and are intertwined and related to each other. It has been observed that the keywords are mostly shaped in the elds of economy, business and engineering. The top 3 keywords in terms of frequency and centrality have not changed. It is usual for the words Society 5.0 and Industry 4.0 to be in the rst place. Those who work on the phenomenon of Society 5.0 mostly mentioned the phenomenon of Industry 4.0. Because the facts integrate each other. In addition, the word student, the internet of things, arti cial intelligence, industrial revolution, industrial entrepreneurship, sustainability, learning systems, and the fact that it contains common keywords with subjects related to many departments such as engineering education shows that the phenomenon of Society 5.0 is a mutli-disciplinary eld. However, the scope of the multi-disciplinary eld is still controversial due to the fact that the case is new.  The words with the strongest citation bursts; They are listed as "sustainable development", "japan", "computation theory", "energy management system", "economic development". These words are mostly related to economic developments and show a tendency towards sustainable business and economy.
Together with the citation bursts, it is seen whether there is a change between the topics that were spoken in trend between 2017-2018 and the topics that were mostly spoken in recent years. On the basis of the common keyword of the case, it was observed that the only trend word was "energy management system" in 2017. In the following process, it was determined that the keywords "economic development", "internet of thing", "cyber physical system", "competition" became a trend in 2018. When the common key developments were examined in 2019, it was seen that the tendencies of data collection, internet of things, signal processing, industrial organizations, computer and information technologies were higher.
Sustainable development in 2020-21 Terms such as innovation, technology, etc. The reason why terms such as Society 5.0, Industry 4.0 and Industrial Revolution are not included in the citation bursts is because they are not an instantaneous phenomenon, but are always trend terms that concern the general lines of the subject. These words are the keywords that have been studied more than in the previous periods. Especially the last two words are important keywords that have increased rapidly in frequency and centrality, although they have entered the trend list in 2020 and are still new terms. Keywords refer to previous terms. Industry 4.0 based cyber physical system uses embedded system to communicate and connect via IOT (trend keyword of 2018). Thus, the connection between physical and digital systems is established and personalized (Peraković et al., 2020;205). Therefore, it is usual for cyber-physical systems to be the trend in 2018 and then to develop embedded systems. With the implementation of these systems in the future, new terms can be created in the same eld and these new terms can cooperate with different elds.
When the common keyword trends are examined in general in the case of Society 5.0; economy (sustainability), engineering and technology elds were seen to be the focus of attention. The phenomenon of Society 5.0 is an issue that concerns all areas of society. Ultimately, not only the economic aspect of the Society 5.0 phenomenon, but also the social aspect dominate with the smart society understanding.
Cluster analysis has been carried out in order to examine and interpret the keywords in detail today and to predict the future keywords in the light of the suggestions of the obtained documents. For this purpose, a common keyword cluster map is drawn in Fig. 5.
Modularity (Q) value: 0.6606 and Silhouette (S) value: 0.9019 are quite good gures. According to the modularity value, it has been seen that each cluster is properly separated. According to the silhouette value, it is obvious that the clusters are resolved quite well. LLR (Local Linear Regression) algorithm was used to label the clusters. 9 sets of keywords emerged. The largest of the clusters is #0; It contains 40 keywords and an average S value of 0.842, #1; It has 31 keywords and pretty good S values of 0.978. Table 7. shows the rst 5 of the clusters in order of size. However, 9 clusters were also included in the analysis. The rst four terms of the values obtained with the LLR are at close levels. The labels in each cluster were selected from the keywords in the articles with the log-likelihood ratio (LLR) weighting algorithm, which is a measure that calculates the weighting coe cient of the keywords in the cluster. Silhouette values given in the table are quite good and it is seen that the keyword sets are resolved appropriately. Keywords in the clusters, if they are in the document titles, have automatically changed to yellow background.
In the #0 cluster with 40 keywords; The year 2019 is considered as the average year. The terms aim to establish infrastructure systems for data performance, as well as to realize sustainable infrastructure evolution and sustainable development. In the #1 cluster with an average year of 2020, it was seen that the most studied subjects were learning techniques, learning stages, the concept of studentship and competency assessment. In cluster #2, whose average year is 2018; It is seen that the tendency to robotic technologies is high. #3 and #4 indicate similar average years and include süper-smart societies, security structures of societies and future work, social perspectives, cyber-physical systems and self-control systems. In other clusters, it was observed that technology, economy, engineering, health care and medical elds were emphasized.

In the table above, documents with a coverage ratio of less than 5% were not included in the chart, but were included in the analysis. It has been tried to gain a broad perspective by examining the representative documents. K. Matsuda's article in cluster #0 corresponds to 7% of the keywords belonging to the cluster and the study carries the most relevant keyword document associated with the cluster. According to this study of Matsuda et al. (2019); With Society 5.0, a new idea of production technologies emerged. The advertising and proliferation of the 5G network will bring a revolutionary technological advance in production management by accommodating new technical networks. Other studies within the same cluster are focused on sustainable development. In this cluster, it has been observed that economic factors and studies on the creation of infrastructure in working life are predominant.
The work of A. Z. Ilma et al. in cluster #1 covers 9% of the keywords belonging to the cluster. In this study (2020), interview was conducted which showed that assessment for learning is useful in redesigning more online learning strategies to improve students' abilities in the 21st century. Other studies in the same cluster were also studied in the elds of quali cation training for competency assessment.
In cluster #2, J. Takase et al. corresponds to 9% of the keyword coverage in the cluster. In this study (2018), special attention was paid to concepts such as sharing information, new values, low birth rate, aging and local population decline; It has been stated that reductions against poverty and wealth gap will be realized with robotic technology. In other documents of the same cluster, intelligence generation and automation systems, public health, IOT smart technologies, certain statistical analyzes were made.
In the #3 cluster, the study of Y. Shiroishi et al., (2018) corresponds to 6%. In the study, based on Keidanren's United Nations Sustainable Development Goals, the policies to reduce the poverty of the Society 5.0 phenomenon, increase the welfare of the society and protect the world are mentioned. Other documents of the same cluster are also aimed at services for the society. Finally, it has been seen that one of the main purposes of the Society 5.0 phenomenon is the service to the smart society and individuals. However, it is debatable whether this cluster is at a su cient level for the subjects studied in social sciences.
The only work covered in cluster #4 is A.V. Mavrodieva and R. Shaw (6%). The study (2020) aims to ensure sustainable development by focusing on disaster risk and climate change policies in the case of Society 5.0. Study subjects of other articles in the same cluster; focused on security challenges in smart societies, the use of medical arti cial intelligence, and the importance of innovation and values in the transition with the phenomenon of Society 5.0.
The subjects studied in the representative documents in the #5 cluster with a silhouette value of 0.971, whose average year is 2017; medical arti cial intelligence, smart pandemic management and 4d mathematical modeling systems. The average year of the #6 cluster was 2020, and the Silhouette value was 0.862; It has been observed that researches are carried out in more ecosystem and working conditions-oriented areas such as exible decision-making systems, smart pandemic management, innovative ecosystem transformation, and sustainable working conditions. In the #7 cluster, whose average year was 2018, the Silhouette value was 0.961; It has been seen that there are many studies on education policies, open data performance expectations, and best practices for the Internet of Things. In the #8 cluster, the average year was 2019 and the Silhouette value was determined as 0.980; It has been seen that computer-based studies such as visual analytical framework, cyber-physical systems, conditional monitoring, open data performance expectations are at the forefront.
As a result of the general analysis of all these clusters and considering the number of keyword nodes and links; In addition to this, it is foreseen that the subject will gain importance day by day, as well as the expansion of the dimensions of the multi-disciplinary structure by increasing the connections in the coming years. At this point, the important thing will be to specialize in the subjects studied and to start and continue studies on subjects that are considered incomplete and that deal with society.

Conclusion
The literature trends of 151 articles in accordance with the CiteSpace application scienometric analysis from the Scopus database, analysis of countries and references, and detailed analyzes of keywords (collaboration, burst points, centrality levels, cluster analysis, document analysis) were made within the framework of the interpretive paradigm. The content of the aforementioned analyzes has been discovered and interpreted. In particular, this paradigm has been important in the interpretation of the relations established after the discoveries and cluster analyzes in the analysis.
The study aimed to gain a holistic and systematic perspective on the phenomenon of Society 5.0. In addition, there are various restrictions. In the future, in addition to Scopus scope, a wide range of research can be carried out in the Web of Science and Google Scholar databases with different search options.
While this phenomenon cumulatively increases its scope in the literature over time, the inclusion of other databases in the analysis will also help in the emergence of more comprehensive ndings.
When the trends in the literature are examined, the Society 5.0 eld is currently developing and is expected to continue its development in the future. The fact that the phenomenon of Society 5.0 is included in the elds of multi-disciplinary expands its scope. In the analysis of the countries' cooperation, it has been seen that Japan, Indonesia and the USA on the basis of quantity and countries such as the USA, Japan, Poland and Russia on the basis of centrality constitute an important scope in the literature.
When cooperation is examined, it is seen that the country that cooperates the most is the USA. In the reference analysis, it was seen that the works of authors such as Y. Shiroishi et al., M. Fukuyama, R. Miśkiewicz, B. Salgues were at the forefront. It has been observed that the documents, which are high in number and centrality level of the cited studies, were taken as reference for the purpose of promoting the Society 5.0 phenomenon in general terms, and to indicate its technological and economic structures. As the phenomenon becomes specialized in different elds, it is predicted that these general expressions will evolve in those elds.
Keyword cluster analysis provides guidelines for the future. It is foreseen that the studies will be in the trends of innovation education, data literacy, complex problem solving, critical thinking, taking arti cial intelligence technology to advanced levels and pandemic management (especially coping with the coronavirus epidemics) in 2021 and beyond. Because when the keywords are considered over the years, it has been seen that the previous period forms the basis for the next period because it has a complementary structure. According to the report shared by the World Economic Forum in 2020, it has been seen that there are ndings similar to the prediction. Technologies that are likely to be adopted in companies include concepts such as data analysis, internet of things, cyber security, arti cial intelligence, cloud computing, robotic studies, virtual reality. To this end, it is envisaged that companies' demands for workers should be based on quali cations such as critical thinking and complex problem solving, selfmanagement and technology use.
It has been observed that the keywords included in the phenomenon of Society 5.0 have changed dimensions over time and shifted to multi-disciplinary elds. Keywords in cluster analysis; It was observed that studies on health, engineering, mathematics, technology and economy were predominant.
When all these clusters are evaluated in general, it is seen that the other 7 clusters have a similar structure despite 2 clusters (#3 and partially #4). In the studies in which the keywords common to the Society 5.0 keywords are included, it has been observed that social perspectives are lacking and instead sustainable development, infrastructure stages and technological developments (internet of things, computer information systems etc.) come to the fore. Since studies on areas such as sociology, psychology, social policy, and gerentology are limited and the phenomenon of Society 5.0 has a structure that directly concerns the society (Keidanren, 2018;17), it is recommended that studies be developed in a multidisciplinary framework based on social sciences.
