Abstract: A server, a method for controlling thereof, and a method for controlling an electronic apparatus are provided. The method for controlling the server according to an embodiment includes: obtaining road information in a region having a predetermined range and information on a plurality of places in the region; obtaining a region mobility graph corresponding to the region, based on movement information of at least one user between the plurality of places, the region mobility graph including a plurality of nodes corresponding to the plurality of places and an edge connecting the plurality of nodes; learning the region mobility graph, by using a graph convolutional network (GCN) model for predicting a relationship between the plurality of nodes in the region mobility graph; and providing the learned region mobility graph to an external apparatus.

Abstract: A method of providing information related to placing an object in a space includes obtaining three-dimensional spatial data corresponding to the space and object-related data for first objects in the space, obtaining a spatial graph including positional relations between the first objects in the space, based on the three-dimensional spatial data and the object-related data, receiving a user input for changing an object placement in the space, based on the user input, adding, to the spatial graph, an empty node representing a second object to be placed in an empty region in the space in which the first objects are not placed, updating the spatial graph by applying, to a graph neural network (GNN), the spatial graph to which the empty node has been added, and outputting object placement change-related information for the space, based on the updated spatial graph.
