| 摘 要： | 科学知识借助引用关系发生动态扩散,客观记录科学发展与演化的轨迹。由于知识之间存在千丝万缕的联系,以孤立的观点看待科学知识的影响与价值往往得到的是片面的感观。本文从联系的视角观察科学知识产出,尝试通过被引、引用、文献耦合与共被引等文献关系为单篇论著构建引文扩散网络,探讨"文献嵌入网络"的概念、测度方式及其在引文扩散过程中起到的特殊作用。案例分析显示,科学知识的形成相伴于科学知识网络的发展,同时也受到这个网络的影响:科学知识向科学领域的扩散,遵循从核心领域向周边领域的扩散模式;施引文献可以揭示目标文献中没有显式呈现的信息;四种文献关系之间可能存在相当程度的重合,引文扩散过程显示出知识的"黏滞性"与非常明显的"小世界"特征。对科学产出的扩散网络进行量化有助于为全面评价其价值提供更多客观依据。

| Abstract: | Scientific knowledge diffuses via citation relationships, objectively recording the trajectory of the development and evolution of science. Due to the inextricable connections in scientific knowledge, an isolated view of the impacts and values of scientific knowledge often leads to one-sided perceptions. In this paper, we observe the outputs of scientific knowledge from the perspective of connections. We try to construct the diffusion networks of individual publications through bibliographic relationships such as citing, coupling, and being cited and co-cited, and to examine the literature-embedding networks concepts, measurements, and role in citation diffusion. The case study suggests that the codification of scientific knowledge accompanies the development of its network, and, at the same time, is influenced by the network. Scientific knowledge diffuses from domestic domains to peripheral domains as time goes on. Citing publications could reveal valuable information about the target publication that is not explicitly recorded. The four types of bibliographic relationships may frequently overlap, causing the significant characteristics of"stickiness"and"small world"in citation diffusion. Our quantification of the diffusion networks provides additional objective evidence for evaluating the values of scientific output. |
