A layered framework to study collaboration as a form of knowledge sharing and diffusion

作者：

Highlights：

• Collaboration is presented as a form of knowledge sharing and hence of knowledge diffusion.

• A layered framework for collaboration studies is proposed.

• The notions of relative and absolute proper essential node (PEN) centrality are introduced as indicators of a node's importance for diffusion of knowledge through collaboration.
