Public transport agencies use social media as an essential tool for communicating mobility incidents to passengers. However, while the short term, day-to-day information about tran…
Graph Energies of Egocentric Networks and Their Correlation with Vertex Centrality Measures
Mikołaj Morzy, Tomasz Kajdanowicz
Graph energy is the energy of the matrix representation of the graph, where the energy of a matrix is the sum of singular values of the matrix. Depending on the definition of a mat…
Priority Attachment: a Comprehensive Mechanism for Generating Networks
Mikołaj Morzy, Tomasz Kajdanowicz, Przemysław Kazienko +2
We claim that networks are created according to the priority attachment mechanism and we show a simple model which uses the priority attachment to generate both synthetic and close…
