摘要
[目的/意义]通过揭示科学发现所引发的知识演进过程以及过程中的知识流动规律,更好地把握科学发现价值,为科研产出评价和科研政策制定提供决策参考。[方法/过程]结合生命周期理论和文本主题性质,提出基于级联引文和直接引文两个视角的科学发现知识演进分析框架。一方面,从级联引文角度出发,利用引文主路径分析科学发现间接引发的知识演进过程;另一方面,从直接引文角度出发,通过引文主题时间分布和主题强度探究科学发现直接带动的知识演进过程。[结果/结论]以石墨烯的成功制备为例对石墨烯领域科学发现的知识演进展开研究,发现级联引文角度和直接引文角度的知识演进均遵循"科学发现—技术研发—产业应用"这一规律。
[Purpose/significance]By explicitly revealing the process of knowledge evolution caused by scientific discovery,the routines of knowledge flow and the value of scientific discovery can be recognized better,which is helpful to provide opinions for scientific research evaluation and policy formulation.[Method/process]According to life-cycle theory and text topic features,this paper proposes a framework for analyzing knowledge evolution of scientific discovery through investigations of cascade citations and direct citations.Cascade citation investigation uses main path to observe the knowledge evolution process transitively triggered by scientific discovery,and direct citation investigation explores the knowledge evolution process directly driven by scientific discovery through sequential distribution and intensity calculation of direct citation topics.[Result/conclusion]Taking the successful preparation of graphene as a case study,it is found that the knowledge evolution process through the two above investigations follows the routine of"scientific discovery-technology development-industry application".
