Interacting Innovation processes: case studies from Reddit and Gutenberg

The existing literature about innovation processes focuses on a single process at a time and proposes models and tools in order to characterize how novelties arise, diffuse and initiate further novelties inside the considered process. However, it is doubtless important to understand if and how different innovation processes influence each other. In this work, we introduce an extremely general model for a collection of innovation processes in order to model and analyze the interaction among them. We provide theoretical results, analytically proven, and we show how the proposed model fits the behaviors observed in some real data sets (from Reddit and Gutenberg). It is worth mentioning that the given applications are only examples of the potentialities of the proposed model and related results: due to its abstractness and generality, it can be applied to many interacting innovation processes.
