基于论文合著网络的学术社区分析方法研究——以《美国地理学家联合会会刊》为例

Analyzing Academic Community Based on Co-author Network

【目的】对论文合著网络进行分析,划分并分析学术社区,发现领域发展与变化规律。【方法】利用社区快速发现算法识别合著网络中的学术社区,建立学者论文影响力与合作影响力的综合指标,评价学术社区中学者的学术影响力,并以学术影响力最大的三个社区为例,从生命周期的角度分析和讨论学术社区的发展和演化。【结果】基于《美国地理学家联合会会刊》的数据分析表明:本文提出的综合指标能够有效地挖掘学术社区中的杰出学者;基于生命周期的合著网络中学术社区分析方法可以发现不同学术社区的研究趋势和热点变化。【局限】以单一期刊为例,可能导致学术社区的组成相对单薄,增加不同来源的期刊数据能够进一步提升研究结果的可信性。【结论】本文提出的学术社区分析方法,可以从不同角度发现与解释领域的发展方向和规律,为相关领域学者的研究工作提供更加科学的指导和认识。

[Objective] This paper aims to categorize and evaluate the academic communities and identify their development and changing rules by analyzing the co-author network. [Methods] First, we used the fast community discovering algorithm to locate the academic communities from the co-author network. Then, we proposed an index to evaluate the academic impacts of scholars from the retrieved academic communities. Finally, we chose three most influential communities to explore their life cycles. [Results] Based on the data of the Journal of Annals of the Association of.4merican Geographers, the proposed index could effectively identify leading researchers as well as the changing trends of research topics. [Limitations] We only collected data from one journal, which might yield in-complete results. [Conclusions] The proposed method could analyze the academic community from various aspects and provide scientific knowledge for scholars from different fields.
