摘要
在学科界限日益模糊、学科壁垒逐渐被打破的背景之下,通过跨学科知识交流行为获得不同学科知识来解决更加综合、复杂的学术问题成为越来越多的学者选择的研究模式。为识别推动跨学科知识交流行为发生的动力大小以及跨学科知识交流的热点方向,本文构建了生态学与物理学交叉视角下的跨学科知识交流动力模型。(1)将物理学中势能的相关概念和生态学中生态位的相关概念移植至跨学科知识交流领域,并论证其可行性与必要性;(2)以知识主体的知识存量为基础,融合知识主体所处网络结构特征和知识主体的知识生态位宽度,计算知识主体的跨学科知识交流势能;(3)以知识主体间的跨学科知识交流势能差为基础,结合主体间的知识生态位重叠度,量化知识主体间的跨学科知识交流趋势,构建知识主体维度的跨学科知识交流动力模型;(4)以知识交流网络为研究对象,描述整个网络的跨学科知识交流行为活跃程度和网络的演化进程,构建网络维度的跨学科知识交流网络演化动力模型。最后,本文以health informatics领域下学者的跨学科知识交流网络为实证数据,对模型进行验证,并分析跨学科知识交流网络的演化进程和规律。
An increasing number of scholars use diverse knowledge via interdisciplinary knowledge communication to solve more comprehensive and complex academic problems against the background of blurred subject boundaries and broken disciplinary barriers.In order to identify the dynamics and development direction of interdisciplinary knowledge communication behavior,this study constructs a power model of interdisciplinary knowledge communication from the perspectives of ecology and physics.First,the concepts of potential energy in physics and ecological niche in ecology are transplanted into the interdisciplinary knowledge communication field.Second,based on the researchers’knowledge base,the interdisciplinary knowledge communication potential energy is calculated by integrating the network structure characteristics and knowledge niche width of the knowledge subject.Then,based on the potential energy difference of interdisciplinary knowledge communication and overlap degree of knowledge niche among scholars,the trend of interdisciplinary knowledge exchange among scholars is quantified,and a power model of interdisciplinary knowledge exchange from the perspective of scholars is constructed.Taking the knowledge communication network as a research object,this study de‐scribes the activity of interdisciplinary knowledge communication behaviors and the evolution process of the entire aca‐demic ecosystem and constructs a power model of the network evolution.Finally,the power model is verified by using the interdisciplinary knowledge communication network of scholars in the field of health informatics as experimental data,and the evolution process and characteristics of interdisciplinary knowledge communication in network are analyzed.
