基本主路径方法用于分析主路径存在关键文献涵盖不足以及非关键文献涵盖较多的问题。本文构建一种基于引文路径叠加的主路径发现方法。该方法认为每篇文献的参考文献均隐含一条路径,将某一领域大量的这种研究路径叠加在一起,构成这一领域的路径网络;那些叠加次数最多的路径构成这一领域的主路径。通过局域和全局搜索方法将主路径提取出来。采用超导材料领域的专利验证了这一方法的有效性。

The main path analysis method is used to analyze the problems of insufficient coverage of key literature and more non-key literature occurring in the main path.In this paper,we propose a new main path discovery method based on the citation path superposition.This paper considers that there is a hidden research path in the reference of each piece of literature and that a large number of such research paths in a given field are superimposed to form the path network in it.The paths with the most overlap times constitute the main path in the field and are then extracted by the local search and glo...
