作者：

Highlights：

• Improved Subject-Action-Object (SAO) network-based method for analyzing trends in technology development.

• Constructing an SAO network based on SAO links.

• Calculating the strength of the relationship between Subject and Object.

• Identifying technology trends based on structural holes, changes in degree distribution, and shifts in network centrality.
