In this paper, we aim to explore the common characteristics shared by important ports by analyzing the network of connections formed by vessel movement among them. To accomplish this task, we adopt a bottom-up network construction approach that combines three years’ worth of AIS (Automatic Identification System) data from around the world, constructing a Ports Network that represents the connections between different ports. Through such representation, we use machine learning to measure the relative significance of different port features. Our model examined such features and revealed that geographical characteristics and the depth of the port are indicators of a port’s significance to the Ports Network. Accordingly, this study employs a datadriven approach and utilizes machine learning to provide a comprehensive understanding of the factors contributing to ports’ importance. The outcomes of our work are aimed to inform decision-making processes related to port development, resource allocation, and infrastructure planning in the industry. |\n\n1. Introduction  \nThe significance of seaports has attracted considerable attention across various disciplines, encompassing economics, environmental studies, and social sciences. Understanding the functions and importance of seaports (hereafter referred to as ports) is crucial for studying vessel movements, identifying key hubs, and assessing the capabilities and potential of the port system. One widely adopted method for evaluating a port’s importance is examining its relationships with other ports regarding vessel routes and port visits.  \nThis often results in creating a Ports Network where the ports are the nodes, while the edges are connections between ports. These connections can represent the sequence of visits of vessels to ports [1] or other points of interest [2, 3] . The modeling of ports and their relationships as a network has enabled the application of complex network or graph theory approaches to investigate ports’ characteristics and roles [4– 7] . Graph theory enables the investigation of ports from a topological perspective [8], hence identifying the role of the port in terms of an interconnected entity (a complex system) . A typical output of complex network approaches applied to Ports Network is understanding ports centrality [9–11] .  \n∗ Corresponding author  \n [emanuele.carlini@isti.cnr.it](emanuele.carlini@isti.cnr.it) (E.
