Knowledge Integration and Diffusion: Measures and Mapping of Diversity and Coherence

  • Ismael RafolsEmail author


In this chapter, I present a framework based on the concepts of diversity and coherence for the analysis of knowledge integration and diffusion. Visualisations that help to understand insights gained are also introduced. The key novelty offered by this framework compared to previous approaches is the inclusion of cognitive distance (or proximity) between the categories that characterise the body of knowledge under study. I briefly discuss different methods to map the cognitive dimension.


Cosine Similarity Cognitive Diversity Cognitive Dimension Knowledge Integration Knowledge Diffusion

This chapter summarises work carried out with many collaborators, in particular with L. Leydesdorff, A.L. Porter and A. Stirling. I am grateful to D. Chavarro for writing the code in R language to compute diversity. I thank Y.X. Liu, R. Rousseau and A. Stirling for fruitful comments. I acknowledge support from the UK ESRC grant RES-360-25-0076 (“Mapping the dynamics of emergent technologies”) and the US National Science Foundation (Award #1064146—“Revealing Innovation Pathways: Hybrid Science Maps for Technology Assessment and Foresight”).
