Using User Feedback to Measure the Social Impact of Urban Digital Services: A Case Study of the Unified Resident Card of Saint-Petersburg
P. 248–253.
Nizomutdinov B., Olga G. Filatova
The modern development of urban digital services greatly simplifies the interaction of citizens and authorities, making it urgent to find new approaches to analyze their effectiveness. The study examined user reviews of the Unified Map of St. Petersburg mobile application as a data source for evaluating the social effectiveness of electronic services. The main hypothesis is that user reviews are a significant indicator reflecting the satisfaction of citizens and the level of their involvement in the process of digital interaction. A parser was developed for the analysis, which collected more than 600 reviews from the Google Play Market platform. The collected data, which included text comments and user ratings, were processed, classified, and thematically modeled using the LDA (Latent Dirichlet Allocation) method. This allowed us to highlight key topics related to the functionality of the application, the quality of its implementation, the user-friendliness of the interface and user suggestions for its improvement. The analysis of user ratings revealed the most problematic and positive aspects of using the application. The official responses of the developers were also analyzed, which made it possible to assess the current level of feedback and interaction with citizens.

The stability of the heliopause, the tangential discontinuity separating the solar wind from the interstellar medium, is influenced by various processes, including the Kelvin–Helmholtz instability. This study investigates the role of charge exchange collisions between protons and hydrogen (H) atoms in reduction of the Kelvin–Helmholtz growth rate at the heliopause. Using a two-dimensional gasdynamic model ...

Abstract: Motivated by the fast development of various additive manufacturing technologies, we
consider a mathematical model of re-solidification of multicomponent metal alloys, which takes place
after ultrashort (femtosecond) pulse laser melting of a metal surface. The re-solidification occurs
under highly nonequilibrium conditions when solutes diffusion in the bulk liquid cannot be described
by the classical diffusion equation of parabolic ...
