中文科研论文未被引探索Ⅲ：科学交流相关性情境下的竞争-选择机制

目的/意义]与众多基于未被引现象的统计分析不同，本文利用演绎分析方法探索论文未被引的产生机制。方法/过程]将未被引现象置于科学交流的宏大背景下，提出论文未被引的竞争-选择机制，指出竞争-选择机制是以文献内容为基础的相关判断与抉择过程，同时受到文献外在特征的深刻影响，以此为基础从时间维度及空间维度展开具体分析过程。结果/结论]从时间演化角度上看，新旧相关文献间的竞争是引发论文未被引现象的主要原因；从时间截面上看，在问题解决循环往复过程中，文献查询、文献参考及新潜在相关信息表达中的同质文献竞争是产生论文未被引现象的重要原因，而引用选择是以竞争为背景的自发自组织过程。

Part Ⅲ of the Exploration on Uncited Papers in Chinese: The Competition- selection Mechanism under the Context of Relevance in the Scientific Communication

Purpose/significance] In this paper, the deductive analysis has been used to explore the mechanism of uncitedness, which is different from other studies where the statistical analysis is used to describe and interpret the uncitedness. Method/process] Under the grand background of the scientific communication, the competition-selection mechanism was given to interpret the uncitedness. This was a procedure of the relevant judgment and selection related to document contents and was influenced greatly by its external characteristics at the same time. Some analysis was given in the time and space dimension based on the competition-selection mechanism. Result/conclusion] In terms of the time evolution dimension, the competition between old and new literatures are the main cause of the uncitedness; in terms of the time section, the competition among homogeneous literatures is an important reason of the uncitedness, which is related to the literature searching, the document reference and the expression of new potential related information in the problem-solving iterative processes. The citation selection is a spontaneous self-organized process based on the competitive context.
