Bi-directional h-index: A new measure of node centrality in weighted and directed networks

作者：

Highlights：

• Bi-directional h-index is a centrality measure in weighted directed networks.

• Bi-directional h-index is calculated iteratively using h-index algorithm.

• We prove the convergence of the iterative process after finite iterations.

• An asynchronous updating process is provided to calculate the limits.

• Bi-directional h-index establishes a greater conceptual framework.
