On ...Library Science Education(LSE) in China has undergone almost one hundred years. This paper discusses and explores the development of the LSE and its interaction with the society in mainly three historical periods. On one hand, this paper analyzes the influences of the social, economic, political, educational, cultural, and scientific and technological environments on LSE’s system, scale, thought, mode, and content from a theoretical perspective;on the other hand, it points out that the LSE promoted and supported the development of the society through cultivating talents and disseminating knowledge. LSE had cultivated a number of outstanding professionals during the period of Republic of China(1911-1949). However, due to the lack of a good interaction with the society, the development of LSE was constrained by the social environment in this period. From 1950 to 1977, the development of the LSE was still relatively slow in spite of the improved social environment in China. From 1978 to present, the LSE has made remarkable contributions to the Chinese society as a result of fundamental social changes in China. This paper proposes that, in order to establish a good interaction between the LSE and the society in China, it is necessary to ensure the unity of self-independence and social dependence, instrument rationality and value rationality, dynamism and stability of the LSE.展开更多

This paper describes a practice of a medical library in providing online access to health information for the general public.Design/methodology/approach: A four-step workflow is developed to integrate and disseminate heterogeneous health information from medical associations. First, a raw data repository is developed to manage the original submissions from information providers.Second, each document in the raw data repository is represented in a standardized XML schema. Third, the medical terms are identified and manually annotated, enriching the semantics of health information. Lastly, all the semantically enriched XML documents are converted to HTMLs for online dissemination.Findings: A health information website, CHealth, was developed for Chinese speakers. It provides free online access for all without any login or IP constrains. CHealth is available at www.chealth.org.cn.Research limitations: The current workflow is time-consuming and labor-intensive due to the lack of information submission/exchange standard and commonly agreed-on consumer health terminology in Chinese.Originality/value: In this work, the target audience of the medical library has been extended from traditional academic/professional to the general public. Methodologies in library sciences have been combined with those in consumer health informatics in CHealth development.展开更多

Traditional metrics have a certain one-sidedness in the evaluation of disciplinary literature and cannot evaluate the impact of literature on the web;while Altmetrics can count how literature is followed and utilized on the web, which is a complement to the traditional measurement methods. Therefore, it is necessary to evaluate the impact of academic literature based on Altmetrics, and combining it with traditional citation indicators can strengthen the credibility and objectivity of academic evaluation and promote better dissemination and communication of academic results. Against this research background, this paper combed through the most influential articles in the field of library and information science in recent years, analysed the literature on library intelligence in the WOS database, identified current research hotspots in the field of library and information science, and predicted potential research hotspots in the future. This study may provide a reference for the research and development of the discipline.展开更多

Second, high-frequency keywords are selected to generate weak tie co-occurrence networks. By removing the internal lines of clustered sub-topic networks, we focus on the analysis of weak tie subnets’ composition and functions and the weak tie nodes’ roles.Findings: The research topics’ clusters and themes changed yearly; the subnets clustered with technique-related and methodology-related topics have been the core, important subnets for years; while close subnets are highly independent, research topics are generally concentrated and most topics are application-related; the roles and functions of nodes and weak ties are diversified.Research limitations: The parameter values are somewhat inconsistent; the weak tie subnets and nodes are classified based on empirical observations, and the conclusions are not verified or compared to other methods.Practical implications: The research is valuable for detecting important research topics as well as their roles, interrelations, and evolution trends. Originality/value: To contribute to the strength of weak tie theory, the research translates weak and strong ties concepts to co-occurrence strength, and analyzes weak ties’ functions. Also, the research proposes a quantitative method to classify and measure the topics’ clusters and nodes.展开更多

Secondly,compared with weblog users,microblog users are more interconnected,more equal and more capable of developing relationships with people outside their own social networks. Thirdly,the microblogging social network is more conducive to information diffusion than the blogging network,because of their differences in functions and the information flow mechanism. Finally,the communication mode emerged with microblogging,with the characteristics of micro-content,multi-channel information dissemination,dense and decentralized social network and content aggregation,will be one of the trends in the development of the information exchange platform in the future.Research limitations: The sample size needs to be increased so that samples are more representative. Errors may exist during the data collection. Moreover,the individual-level characteristics of the samples as well as the types of information exchanged need to be further studied.Practical implications: This preliminary study explores the characteristics of information diffusion in the network environment and verifies the feasibility of conducting a quantitative analysis of information diffusion through social media. In addition,it provides insight into the characteristics of information diffusion in weblogs and microblogs and the possible reasons of these differences.Originality/value: We have analyzed the characteristics of information diffusion in weblogs and microblogs by using the social network analysis methods. This research will be useful for a quantitative analysis of the underlying mechanisms of information flow through social media in the network environment.展开更多

It has extensive cooperation relationships with other fields. The position of LIS has also become centralized, and its interdisciplinary cooperation has increased. For both EM and LIS, we observed ＂small-world＂ and ＂scale-free＂ networks, indicating full communication and mature development in both disciplines. Based on a comparison of two institutions in the two fields, we confirmed the comprehensive development in EM and the extensive information exchange in LIS.Research limitations： We collected data only from humanities and social sciences, but did not consider the connection between EM and natural sciences, or between LIS and natural sciences. In addition, the paper lacks analysis of institutional collaboration at the micro level.Practical implications： The paper provides insights into the institutional cooperation characteristics in EM and LIS in China.Originality/value： The paper offers a new perspective on the characteristics of institutional collaboration in China.展开更多
文摘More than twenty years ago,Wuhan University and Nanjing University offered library science(LS)graduate programs.Since then,LS graduate education has been growing quickly in many aspects.At the same time,however,LS graduate education was also facing enormous challenges stemming from the dynamic development and wide applications of information technologies into the pedagogical arena of teaching and learning at all levels.Social evolution also made it necessary for LS educators to re-examine once again their graduate education model,curricular composition,educational philosophy and educational missions.In analyzing the present situation of LS graduate education in China,this paper focuses on the following issues:1)Growing size of LS graduate education(quantity and quality);2)educational objectives,including research direction and placement for graduates;3)structure of knowledge and curricular construction;4)conditions of administering a library school of high quality and 5)the management of teaching resources.The keystone of this paper is to pinpoint where current library science curricular deficiencies are lying.It is hoped that more serious scholarly discussions and perhaps also even concerted efforts among LS scholars and library practioners may be evoked in having the graduate education system of library and information science thoroughly realigned for the informational needs of the 21st century.

文摘Purpose： This study analyzes the current status of institutional cooperation in economics and management （EM） and library and information science （LIS） in China.Design/methodology/approach： Based on the Chinese Social Science Citation Index （CSSCI） database, we constructed institutional collaboration networks in EM and LIS, and analyzed the collaboration characteristics through social network analysis.Findings： In the development and evolution of the collaboration network of institutions in humanities and social sciences, EM is always at the center. It has extensive cooperation relationships with other fields. The position of LIS has also become centralized, and its interdisciplinary cooperation has increased. For both EM and LIS, we observed ＂small-world＂ and ＂scale-free＂ networks, indicating full communication and mature development in both disciplines. Based on a comparison of two institutions in the two fields, we confirmed the comprehensive development in EM and the extensive information exchange in LIS.Research limitations： We collected data only from humanities and social sciences, but did not consider the connection between EM and natural sciences, or between LIS and natural sciences. In addition, the paper lacks analysis of institutional collaboration at the micro level.Practical implications： The paper provides insights into the institutional cooperation characteristics in EM and LIS in China.Originality/value： The paper offers a new perspective on the characteristics of institutional collaboration in China.
