Title
A layered framework to study collaboration as a form of knowledge sharing and diffusion
Author
Abstract
 Collaboration can be described using layered systems such as the articleauthorinstitutecountry structure. These structures can be considered cascades orchains of bipartite networks. We introduce a framework for characterizing and studyingthe intensity of collaboration between entities at a given level (e.g., between institutions).Specifically, we define the notions of significant, essential and vital nodes, and significant,essential and vital sub paths to describe the spread of knowledge through collaboration insuch systems. Based on these notions, we introduce relative and absolute proper essentialnode (PEN) centrality as indicators of a nodes importance for diffusion of knowledgethrough collaboration.We illustrate these concepts in an illustrative example and show how they can be appliedusing a small real-world example. Since collaboration implies knowledge sharing, it can beconsidered a special form of knowledge diffusion.
