Fuente: Wipo "digitalization" The present disclosure relates to systems, non-transitory computer-readable media, and methods that utilize a data-driven approach to organize user-activity data for a user into a hierarchy of digital actions, digital tasks, and digital workflows and categorize a vector representing frequent activities from the hierarchy into a persona group for the user. From this vector representation, the disclosed systems can categorize the vector representation from among a distribution of other vector representations for other users into a persona group for the particular user. Based on at least one of the determined persona group or the vector representation, the disclosed systems can use a nodal graph to determine a digital recommendation that the particular user collaborate with other users or collaborate on a particular project.
