[目的 /意义]对科学共同体中权威学者的地位与作用开展研究,以合著网络结构分析为视角,将网络分析与高h指数学者的作用研究相结合,从作者节点所处的网络结构与位置中探寻学者的影响力与作用发挥,为科学共同体的实证性研究开辟新的途径。[方法 /过程]以我国图书情报学科为例,选取33位高h指数学者作为研究对象,采集发文数据,提取合著关系,通过构建合著关系网络,采用网络分析技术对节点的中心性、聚集性、结构洞特征等进行分析。[结果 /结论]数据分析表明:绝大部分高h指数学者在网络结构中占据核心位置,学者之间联系紧密,在科学共同体中起到引领学科发展方向、建立和维护学科规范、加强科学交流与知识传播以及培育人才等重要作用。
[Purpose / Significance] To study the status and function of authoritative scholars in the scientific community. From the perspective of co-author network structure analysis, this paper combines the network analysis with the research on the role of high-h index scholars. From the network structure and Position to explore the influence and role of scholars to play, open up new avenues for the empirical study of the scientific community. [Methods / Processes] Taking the librarianship in our country as an example, we select 33 high-h index scholars as the research object, collect the sending data and extract the co-author relations. By constructing the co-relation network and adopting the network analysis technology, Aggregation, structural features such as hole analysis. [Results / Conclusion] The data analysis shows that most of the high-h index scholars occupy the core position in the network structure, and there is a close relationship between scholars. In the scientific community, they play a leading role in disciplinary development, establish and maintain disciplinary norms, and strengthen scientific exchanges And knowledge dissemination and nurturing talent and other important role.
