主路径分析方法研究进展

Literature Review about Main Path Analysis Method

主路径分析方法是一种基于“连通性”降低知识网络复杂程度,提取关键路径的定量和可视化方法,在科学技术发展路径探测中具有重要的实践意义。本文从概念辨析、方法流变和应用实践3个角度对国内外主路径方法研究与应用的相关文献进行系统梳理,旨在明晰主路径分析方法的发展脉络和研究重点,发现已有研究的不足和空白点,总结现有方法在路径探测中存在的问题,提出主路径探测方法改进策略。现有主路径分析方法相关研究的关注重点主要在遍历权重的计算和路径搜索方法的选取等方面,而关键节点的遴选、多元路径的探测及稀疏网络的密度增强等能够提高主路径分析效果的改进策略,值得在未来进行深入研究。

The main path analysis method is a quantitative and visual method based on“connectivity”to reduce the complexity of knowledge network and extract the key path.It is practical significant in the scientific and technological development path detection.This paper systematically combs the relevant literatures for the study and application of the main path method at home and abroad from the three angles of concept analysis,method evolution and application practice.The aim is to clarify the development and research focus of the main path analysis method,to find the shortcomings and blank points of the existing research,to summarize the existing methods in the path detection problems,and to propose the main path detection method to improve the strategy.The focus of the research on the existing main path analysis method is mainly in the calculation of traversal weight and the selection of path search method,and the selection of key nodes,the detection of multiple paths and the density enhancement of sparse networks have a positive effect on improving the analysis effect of the main path,which is worth further studying in the future.
