Title: On the structure of the network of European airports and airlines Authors:  Vladimir Batagelj - IMFM (Slovenia) [presenting]
Abstract: The network of European airports was previously created. It is an example of a multi-relational (multiway) network with links (From, To, Line) -- the company Line flies from the airport From to the airport To. The network contains 450 airports, 37 companies, and 7176 links. Clustering was used to gain insight into the structure of the entire network. To reveal the main part of the network, its core was determined. Both results with an interactive 3D layout in X3D, which provides a detailed insight into the structure of the networks, are presented.
