Framework based on complex networks to model and mine patient pathways
Caroline de Oliveira Costa Souza Rosa, Márcia Ito, Alex Borges Vieira +2
The automatic discovery of a model to represent the history of encounters of a group of patients with the healthcare system -- the so-called "pathway of patients" -- is a new field…
Analysis of account behaviors in Ethereum during an economic impact event
Pedro Henrique F. S. Oliveira, Daniel Muller Rezende, Heder Soares Bernardino +2
One of the main events that involve the world economy in 2022 is the conflict between Russia and Ukraine. This event offers a rare opportunity to analyze how events of this magnitu…
Modelling and Mining of Patient Pathways: A Scoping Review
Caroline de Oliveira Costa Souza Rosa, Marcia Ito, Alex Borges Vieira +1
The sequence of visits and procedures performed by the patient in the health system, also known as the patient's pathway or trajectory, can reveal important information about the c…
BlockColdChain: Vaccine Cold Chain Blockchain
Ronan D. Mendonça, Otávio S. Gomes, Luiz F. M. Vieira +3
In this paper, we propose a blockchain-based cold chain technology for vaccine cooling track. The COVID-19 pandemic has caused the death of millions of people. An important step to…
A Survey on Embedding Dynamic Graphs
Claudio D. T. Barros, Matheus R. F. Mendonça, Alex B. Vieira +1
Embedding static graphs in low-dimensional vector spaces plays a key role in network analytics and inference, supporting applications like node classification, link prediction, and…
You Shall not Pass: Avoiding Spurious Paths in Shortest-Path Based Centralities in Multidimensional Complex Networks
Klaus Wehmuth, Artur Ziviani, Leonardo Chinelate Costa +2
In complex network analysis, centralities based on shortest paths, such as betweenness and closeness, are widely used. More recently, many complex systems are being represented by…
Time Centrality in Dynamic Complex Networks
Eduardo Chinelate Costa, Alex Borges Vieira, Klaus Wehmuth +2
There is an ever-increasing interest in investigating dynamics in time-varying graphs (TVGs). Nevertheless, so far, the notion of centrality in TVG scenarios usually refers to metr…
