[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-driven economy, the diffusion and absorption of disciplinary knowledge greatly promote the disciplinary collaboration, integration, development and innovation. This paper proposes a method with the combination of the quantitative index measurement and the semantic information mining of knowledge to explore the diffusion process of disciplinary knowledge, expecting to enrich and perfect the research paradigms and methods of disciplinary knowledge diffusion, and provide references for knowledge management and decision making. [Method/process] Firstly, on the basis of the classic quantitative index measurement, a systematic study on disciplinary knowledge diffusion was conducted to explore the quantity and theme features of disciplinary knowledge diffusion by using the formal concept analysis and semantic information of disciplinary knowledge. Secondly, a Logistic model of disciplinary knowledge diffusion was constructed and the evolution trend was predicted. Thirdly, an empirical study was further carried on by taking the field of social network as an example. [Result/conclusion] Firstly, the application scopes of knowledge in different disciplines are unceasingly expanded, and the diffusion process of knowledge conforms to the characteristics of power law distribution. Secondly, it shows certain differences of different disciplines to absorb and accept knowledge subjects. Thirdly, the diffusion process of current social network knowledge in different disciplines is in the mature stage.
