[目的 /意义]在知识经济时代,学科知识的扩散与吸收极大地促进了学科的协同、交叉、融合、发展与创新。提出一种量化指标测度与知识语义信息挖掘相结合的学科知识扩散过程探测方法,以期丰富和完善学科知识扩散研究范式与方法,为学科知识管理及决策制定提供可资借鉴的参考。[方法 /过程]在经典量化指标测度的基础上,利用形式概念分析方法,结合学科知识语义信息,对知识在学科中的传播扩散过程进行系统研究,挖掘学科知识扩散数量及主题特征;建立学科知识扩散Logistic模型,并对其演化趋势进行预测;最后,以社会网络领域为例,进行实证研究。[结果 /结论]知识在各学科中的应用范畴不断拓展,其扩散过程符合幂率分布特征;不同学科吸纳和接受的领域知识主题存在一定的差异;当前社会网络知识在学科中的传播扩散进程正处于成熟期。
[Purpose / Significance] In the era of knowledge economy, the diffusion and absorption of subject knowledge has greatly promoted the coordination, cross, integration, development and innovation of disciplines. This paper proposes a method of knowledge diffusion process based on the combination of quantitative measure and knowledge semantic information mining, in order to enrich and improve the research paradigms and methods of disciplinary knowledge diffusion and provide references for the knowledge management and decision-making of subject knowledge. [Methods / Processes] Based on the measurement of classical quantitative indicators, this paper uses the formal concept analysis method and the semantic information of subject knowledge to systematically study the diffusion process of knowledge in disciplines and to explore the quantity and theme features of knowledge diffusion in disciplines. Knowledge diffusion Logistic model, and forecast its evolution trend; Finally, take the social network as an example, carries on the empirical research. [Result / Conclusion] The scope of application of knowledge in various disciplines continues to expand, and its diffusion process accords with the characteristics of power distribution; there are some differences in the field of knowledge topics absorbed and accepted by different disciplines; the diffusion and diffusion process of current social network knowledge in disciplines Is in maturity.
