基于节点重要性的领域主路径发现新探索
Discovering Main Path of a Domain Based on Node Importance
摘要
Abstract
[Purpose/Significance]It firstly discusses the necessities of discovering the main path of a domain from the perspective of the importance of nodes on the basis of summarizing the mainstream methods at present. Then,two key problems involved in the discovering process for the global-connected main path are pointed out:the measurement of important nodes and the reduction of networks.[Method/Process]The first problem can be solved by way of combing revised PageRank and traversal weights. As for the network simplification, Pathfinder is used at first,and then the nodes that disturb the explanation of main paths are ruled out,and finally the"middle end nodes"are bridged to the existing main paths via the shortest path,which is beneficial for the connectivity of the final main path. Lastly,the dis-covery of main path in OLED is demonstrated, and the comparisons between our method and other mainstream methods are carried out. [Result/Conclusion]It shows that the result of our method is more interpretative,comprehensive and scientific,indicating its superiority and proving its effectivity in main path finding. Meanwhile,it provides a new perspective and reference for main path finding of a domain.关键词
