As a research topic integrating various subjects and technologies, Metaverse research has been a global concern in recent years. This study explores the hotspots and frontiers of academic research on the Metaverse based on a bibliometric analysis from 2012 to 2021. A keyword retrieval dataset related to Metaverse research was constructed based on expert consultation and manual reading of the literature, retrieving articles and conference papers from the Scopus database. Critical points in Metaverse research are represented in terms of research scale, keyword co-occurrence networks, keyword citation bursts, and international collaborative networks with the application of VOSviewer and CiteSpace’s bibliometric visualization software. The results indicate that Metaverse research is experiencing rapid growth, with countries/regions increasing their production at varying speeds. The results also indicate the three most prolific countries, the United States, China and Germany, for comparison, showing the leading topic as virtual reality in Metaverse research, and we find that there are differences in topic clustering and hotspot evolution among the three countries over the past decade. By determining the current research status and the overall development path of the Metaverse field, the paper intends to provide a reference for the future research development and technical application of the Metaverse.

ABSTRACT The role of reference and information service has been redefined in some Chinese university libraries. In these libraries the focus of reference and information service has transformed into information analysis. University libraries have been a participant in the management and evaluation in scientific research, technological innovation, and discipline construction. The information analysis service of Zhejiang University Library is a typical case. Zhejiang University library established an information analysis group in 2009 in reference and information service division. To further guarantee the professionalism of service, the information analysis service center was set up in 2018 as a separate division. Over the past decade, information analysis service has played the potential of library in supporting decision-making, scientific research and innovation, discipline construction, research performance evaluation, etc. Information analysis service makes the popularity and status of the university library improve continuously. The evolution of information analysis service of Zhejiang University Library is reviewed in this paper, from the initial stage to the expansion stage, and then to the establishment of professional division. Approaches to promote the progress of information analysis service are summarized. The future goals are also discussed from the perspectives of strengthening the innovation mind-set, librarian development, and information analysis literacy.

Objective. We focused on medical informatics journal publications rather than on conference proceedings by comparing and analyzing the data from journals and conferences from a broader perspective. The aim is to summarize the unique contributions of China to medical digitization and foster more multilevel international cooperation. Method. In February 2019, publications from 2008 to 2018 in three major English-language medical informatics journals were retrieved through Scopus, including the journals, namely, International Journal of Medical Informatics (IJMI, international community), JAMIA (United States), and Methods of Information in Medicine (MIM, Europe). Three major Chinese-language journals, namely, China Digital Medicine (CDM), Chinese Journal of Health Informatics and Management (CJHIM), and Chinese Journal of Medical Library and Information Science (CJMLIS), were searched within the major three Chinese literature databases. The datasets were preprocessed using the NLP package on Python, and a smart local moving algorithm was used as a clustering method for identifying the aforementioned journals. Result. Between 2008 and 2018, the total number of published papers and H-index of the three English-language journals was 1371 and 67 (IJMI), 1752 and 86 (JAMIA), and 637 and 35 (MIM), respectively. In the same period, the total number of published papers and H-index in the three Chinese-language journals was 6668 and 23 (CDM), 1668 and 22 (CJHIM), and 2557 and 25 (CJMLIS), respectively. IJMI, JAMIA, and MIM received submissions from 82, 59, and 62 countries/regions, respectively. By contrast, the three Chinese journals only received submissions from seven foreign countries. The proportions of authors from institutional affiliations were similar between the three English-language journals (IJMI, JAMIA, and MIM) and CJMLIS because the majority of the authors were from universities (81%, 74%, 73%, and 65.2%), followed by medical institutions (12%, 10%, 9%, and 23.4%) or research institutes (2%, 4%, 10%, and 4.3%). Furthermore, the proportions of the authors from enterprises were low (2%, 6%, 4%, and 0.3%) for all journals. However, the authors in CDM and CJHIM were mainly from medical institutions (50% and 40%), followed by universities (33% and 32%) and research institutes (3% and 4%). In addition, the proportions of enterprises were only 3% and 2%, respectively. Among the top five authors in three English-language journals (ranked in terms of the number of published papers), 100% had doctoral or master’s degrees, compared with only 60% in the Chinese journals. Additionally, 28204 different keywords were extracted from the aforementioned papers, covering 275 specific high-frequency key terms. Based on these key terms, four clusters were found in the English literature—“Health and Clinical Information Systems,” “Internet and Telemedicine,” “Medical Data Statistical Analysis,” and “EHRs and Information Management”—and three clusters were found in the Chinese literature: “Hospital Information Systems and EMR,” “Library Science and Bibliometrics Analysis,” and “Medical Reform Policy and Health Digitization.” Only two clusters are similar, and Chinese-language journals focus more on health information in technology and industrial applications than in medical informatics basic research. Conclusion. This study provides important insights into the development of medical informatics (MI) in China and Western countries showing that the medical informatics journals of China, the United States, and Europe have distinct characteristics. Specifically, first, compared with the Western journals, the number of papers published in the journals of professional associations in the field of MI in China is large and the application value is high, but the academic influence and academic value are relatively low; second, most of the authors of the Chinese papers are from hospitals, and most of the counterparts in the Western countries are from universities. The proportion of master’s or doctoral degrees in the former is also lower than that of the latter; furthermore, regarding paper themes, on the one hand, China MI has no theoretical and basic research on medical data statistics and consumer health based on the Internet and telemedicine; on the other hand, after nearly 10 years of hospital digital development, China has fully used the latecomer and application advantages in hospitals and, through extensive international cooperation, has made significant advancements in and contributions to the development of medical information.

Objective: To achieve universal access to medical resources-a partial goal of the second ambitious health reform since 2010-the Chinese government aimed to build a regional medical consortium and enhance the efficiency of health information exchange (HIE). We analyzed the experience of constructing a medical consortium in Chinese hospitals, which was based on regional health information technology (RHIT) promoted by HIE. Method: In this longitudinal study, we analyzed the results of the annual surveys that were conducted by the China Hospital Information Management Association from 2006 to 2015. The survey results mainly concerned whether hospitals should join the regional medical consortium, the methods used for sharing inter-hospital medical data, and the out-of-hospital information interaction system. The Bass diffusion model was adopted to fit and predict the proportion of Chinese hospitals joining the consortium from 2006 to 2025. Result: As of 2015, the survey results of 7272 hospitals were obtained. The proportion of hospitals in partnership systems increased from 3.0% in 2007 to 57.2% in 2015. There has been a rapid development in the electronic sharing of medical data between hospitals. The proportion of hospitals that relied solely on paper documents for data interaction decreased from 43.3% in 2011 to 8.0% in 2015. There was a strong positive linear correlation between hospitals joining the consortium and the accessibility of electronic medical data exchange within hospitals (r = 0.925). The proportions of hospitals that supported dual referral systems and appointments, data browsing between hospitals and regional information systems, and remote consultation services increased to 65.0%, 61.6%, and 81.9% in 2015, as compared to 18.8%, 16.8%, and 10.9% in 2011, respectively. The Bass prediction model showed that the goal of recruiting 90% of the hospitals to the consortium by 2020 will likely be achieved (adjusted R-2 = 0.93). Conclusion: The Chinese government has applied a top-down, high-level design model to promote the rapid development of a medical consortium, in which the RHIT technologies are crucial technical enabler.

BACKGROUND:As the second-largest economy in the world, China has invested considerable financial and policy support into hospital informatization since health care reform in 2010. However, the results and experience of such investments have not been compared with relevant research and applications in the United States and Europe.OBJECTIVES:From the perspective of professional conference proceedings, we comparatively analyzed the current situations, characteristics, hotspots, and trends of medical informatics (MI) development in China, the United States and Europe to help Chinese MI researchers and practitioners summarize their experiences and determine gaps compared to their American and European peers. We also aimed to educate foreign peers about the special contributions of the China MI circle and facilitate multilevel international cooperation.METHODS:English conference proceedings of the American Medical Informatics Association (AMIA) Annual Symposium (USA), Medical Informatics Europe (MIE, Europe) and World Conference on Medical Informatics (MEDINFO, Global) from 2007 to 2017 were searched within Scopus and Pubmed. Proceedings of Chinese MI conferences (CMIAAS, CHINC, CHITEC, CPMI) (China) were searched within Chinese databases CQVIP, CNKI and WanFang during the same period. The datasets were preprocessed via a Natural Language Processing (NLP) package on Python and were qualitatively and quantitatively analyzed via bibliometric methods.RESULTS:Overall, 2285, 1601, 1930 and 5431 papers were publicized from the AMIA Symposium (USA), MIE (Europe), MEDINFO (Global) and Chinese MI conferences (China) between 2007 and 2017, respectively, with an H-index of 32, 19, 19 and 3, respectively. The AMIA Symposium, MIE and MEDINFO received submissions from 43, 68 and 80 countries (or regions), respectively, but Chinese MI conferences (CMIAAS, CHINC, CHITEC, CPMI) only received submissions from 3 foreign countries. Author affiliations were quite similar among the AMIA Symposium, MIE and MEDINFO, as 67%, 75% and 70% of authors came from universities/colleges, respectively; 18%, 10% and 11% came from medical institutions, respectively; and 7%, 8% and 10% came from institutes, respectively. In contrast, the majority (54%) of authors in Chinese MI conferences came from medical institutions followed by universities/colleges (17%) and institutes (10%). Of the top 5 authors with the most publications in AMIA Symposium, MIE and MEDINFO, 14/15 of them had medical backgrounds, but only one author from the Chinese MI conferences majored in medicine. Electronic medical records (EMR) were included in the top 10 high-frequency keywords by all four conference groups, but the amount of time that this keyword appeared differed in 2009, 2011, 2012 and 2013, respectively.CONCLUSIONS:The MI annual conferences are all different among China, the United States and Europe. China lags in the theoretical and discipline bases but has made considerable investments in the past 10 years. China should fully use its second-mover advantage and application advantages and utilize international experiences and cooperation to make stronger contributions to global MI development.

Background: China launched its second health reform in 2010 with considerable investments in medical informatics (MI). However, to the best of our knowledge, research on the outcomes of this ambitious undertaking has been limited.Objective: Our aim was to understand the development of MI and the state of continuing education in China and the United States from the perspective of conferences.Methods: We conducted a quantitative and qualitative analysis of four MI conferences in China and two in the United States: China Medical Information Association Annual Symposium (CMIAAS), China Hospital Information Network Annual Conference (CHINC), China Health Information Technology Exchange Annual Conference (CHITEC), China Annual Proceeding of Medical Informatics (CPMI) versus the American Medical Informatics Association (AMIA) and Healthcare Information and Management Systems Society (HIMSS). The scale, composition, and regional distribution of attendees, topics, and research fields for each conference were summarized and compared.Results: CMIAAS and CPMI are mainstream academic conferences, while CHINC and CHITEC are industry conferences in China. Compared to HIMSS 2016, the meeting duration of CHITEC was 3 versus 5 days, the number of conference sessions was 132 versus 950+, the number of attendees was 5000 versus 40,000+, the number of vendors was 152 versus 1400+, the number of subforums was 12 versus 230, the number of preconference education symposiums and workshops was 0 versus 12, and the duration of preconference educational symposiums and workshops was 0 versus 1 day. Compared to AMIA, the meeting duration of Chinese CMIAAS was 2 versus 5 days, the number of conference sessions was 42 versus 110, the number of attendees was 200 versus 2500+, the number of vendors was 5 versus 75+, and the number of subforums was 4 versus 10. The number of preconference tutorials and working groups was 0 versus 29, and the duration of tutorials and working group was 0 versus 1.5 days.Conclusions: Given the size of the Chinese economy and the substantial investment in MI, the output in terms of conferences remains low. The impact of conferences on continuing education to professionals is not significant. Chinese researchers and professionals should approach MI with greater rigor, including validated research methods, formal training, and effective continuing education, in order to utilize knowledge gained by other countries and to expand collaboration.
