Abstract： Abstract: Purpose/Significance With the rapid development of social informatization, the spread scope and influence of online public opinions are constantly expanding. The analysis of public opinion intention is helpful for government departments to monitor and manage public opinion and create a healthy network environment. This study aims to sort out the development context and frontier trends in the field of public opinion intention recognition, provide direction for future research on public opinion intention recognition, and promote the development and application of the discipline. Method/Process This study discusses the current research status in the field of public opinion intention recognition, defines the concept and sources of public opinion intention recognition, and summarizes the technical methods, application fields, challenges and development directions of public opinion intention recognition. Result/Conclusion It is found that the current intention recognition of public opinion is mainly applied to the research of opinion leaders, early warning of public emergencies, public opinion governance and education. At the same time, the false information in online public opinion, the ambiguity of network language and the limited big data resources bring challenges to the recognition of public opinion intention. In the future, the process of public opinion intention recognition should focus on false information recognition, implicit information mining, algorithm and resource improvement.

Abstract： Purpose/Significance Medical device products are the products of clinical scientific research results transformation and knowledge innovation management. As one of the main competition tracks in the science and technology industry, the strength of medical science and technology is an important aspect to measure the country’s overall scientific research ability and environment. Knowledge innovation drives industrial development, product structure reflects the level of knowledge management, and knowledge management involving frontier science and technology is closely related to national strategic planning. From the perspective of product theme mining and evolution sharing, it is of great strategic significance for enterprises and countries to look into the current situation of domain technical knowledge management. Method/Process A comprehensive approach to technical topic identification and analysis is adopted in this study. Through the application of LDA algorithm in the field of machine learning, potential technical topics are identified and clustered from the medical device product data, and then the distribution characteristics and change rules of technical topics in different periods are analyzed. The future technology trend is predicted quantitatively by using hidden Markov model. Using this combination method, the topic distribution, evolution law and future trend of innovative medical devices from 2014 to 2023 are deeply studied. Result/Conclusion 38 technical topics were identified and sorted out using domestic approved innovative medical device product data. The results show the deep development of genetic testing and implanted electrical stimulator technology. Disease diagnosis, surgical navigation and biological mesh are the focus of future technological innovation and product competition. However, from the perspective of quantitative characteristics, China’s research and development strength is relatively weak, and the innovation ability is in a weak position, which needs to attract the attention of enterprise technology research and development institutions and the government.

Abstract： Background Since August 2022，Shengzhou City of Zhejiang Province has been carrying out the reform of outpatient payment mode in medical insurance，gradually carrying out the reform of capitation by implementing the total budget，updating the calculation standard of capitation fee，improving the incentive and constraint mechanism and other measures，so as to encourage primary health care institutions to provide appropriate basic medical services，reduce primary medical expenses，and promote the sustainable development of medical insurance fund. Objective To analyze the influence mechanism of capitation for outpatient services in basic medical insurance on medical expenses in Shengzhou City，Zhejiang Province，and to provide reference for improving the relevant payment system. Methods Using "capitation" and "medical costs" as both English and Chinese search terms，databases such as CNKI，Wanfang，PubMed and Web of Science were searched for relevant literature on capitation from 2000-01-01 to 2022-07-31，as well as the policy documents，government reports and news reports related to the implementation of capitation from April to July 2022. Personal interviews were conducted with representatives of capitation payment policy makers and implementers in Shengzhou City from September to December 2022（n=13）. A qualitative analysis of capitation reform policy on medical expenses under the total outpatient budget in Shengzhou City，Zhejiang Province was performed by using system dynamics approach. Results The policies of the current round of medical insurance payment reform in Shengzhou were plotted as a cause graph with five feedback loops obtained，showing that the implementation of the total capitation budget policy can motivate primary health care institutions to provide standardized medical services for residents，promote an increase in the contracting rate in primary care，thus controling medical expenses；a scientific capitation fee standard can motivate primary health care institutions to autonomously control and reduce costs；increasing the reimbursement ratio of medical insurance can effectively reduce the medical burden of patients；improving the performance appraisal system is conducive to the continuous improvement of service capabilities of primary health care institutions；strengthening the construction of information sharing mechanisms can achieve data sharing and exchange，and comprehensively improve the health of residents. Conclusion The implementation of capitation reform in conjunction with multiple policy measures can improve the contracting and consultation rates in primary care institutions，broaden the sources of medical insurance fund，ensure the sustainability of medical insurance fund，improve the medical service and capabilities of primary care institutions，improve the health status of residents，and significantly improve the prevention and treatment effect of chronic diseases.

Abstract： The study on systematic identification of “Sleeping Beauty” (SB) publications and on their awaking mechanisms will promote the strategic preservation of documents in libraries, and provide implications for identifying potential “ahead of time” discoveries or transformative research, and shortening time lag for original research to get recognized. Based on the data analysis and case studies, this paper figured out some key characteristics of SB publications. The content of SB papers tends to be multi-discipline research and most of which tend to be published in prestigious multidisciplinary journals with higher impact and wider scope. One is perhaps more inclined to believe that SB relate to more fundamental and basic, and less to application-oriented work. But a surprising finding is that half of the SBs are application oriented and significantly more cited in patents than ‘normal’ papers, which demonstrated the potential technical and application-research properties of SB. The key publications and pioneering works of the recent Nobel Prize winners for physiology and medicine are delayed-cited rather early-cited in the entire citation life-time of an article. We further suggested several clues for early identifying SB. First, Transformative research tend to be neglected or resisted by the scientific community initially and this neglect or resistance could be regarded as the key clue for the early prediction of SB literature. Publications belonging to so-called transformative research, even when less frequently cited than others, should be given special attention as early as possible, because they may suddenly attract many citations after a period of sleep. One could identify transformative research through some text terms (such as "disagree", "overcome", "break", "dispute"...). In order to discern such potential transformative research, we could observe whether the relevant documents get early citation from patents or not, because many SB documents tend to be technical research in nature and application-oriented. Second, the Bcp index proposed in our foregoing paper is more sensitive in identifying the “lower level SBs”, which refers to the case when the total citations and the maximum annual citations of SBs are not so high in comparison with other typical SBs. This index may be used to identify the papers at the sleeping-awakening interface, which provided new tools for arousing attention of the science community to previously overlooked but important research. We also pondered some policy implications about the associations of SB publications with transformative research, research front and research evaluation.

Abstract：[目的/意义] 通过优化提出一个可精准识别睡美人文献的简易无参数指标。[方法/过程] 借鉴睡美人指数（B指数）基本框架，通过将考察对象“年度被引次数”优化为“年度被引次数累积百分比”，提出Bcp指数，重新定义唤醒时间、睡眠深度和唤醒强度。并通过识别Science和Nature上的睡美人文献进行检验。[结果/结论] Bcp指数继承了B指数对那些非常显著的睡美人文献高度敏感的优点。Bcp指数框架下计算出的唤醒时间更符合实际情况，而B指数框架下的唤醒时间易被延迟估计。Bcp指数考虑了观察期内论文全部的引文曲线，规避了B指数无法反映年度被引次数达到最大值以后的引文曲线的缺点。Bcp指数对论文发表之初被引次数的约束效力显著高于B指数，更符合睡美人文献早期零被引和低被引的特征。Bcp指数对年龄大、总被引次数和年度被引次数相对较低的睡美人文献更敏感，有利于挖掘平常易被忽视的非高被引文献中睡美人文献的存在规律。Bcp指数规避了人为参数主观界定的不足，以及不同学科领域论文被引规模差异对睡美人文献统一定义的干扰。
