“…Taking into account the considered features of the information space development, it is advisable to develop a conceptual model of convergence using the entropy approach to knowledge management processed in converged regional information spaces. In particular, considering the structure of the information space of the executive bodies of state power in St. Petersburg, based on the number of modules in information systems based on the data of the State Information Systems of St. Petersburg [9], it is possible to identify groups of clusters of information systems with similar peculiarities, forming synergetic effects from interaction, which was shown in previous studies [3,4]. Thus, taking into account the applied entropy approach and taking into account (1) and (2), the specific entropy of the cluster, taking into account the synergetic effect in the convergence process, will be calculated as follows:…”
