Zou, L. (author), Wang, An (author), Wang, H. (author)Temporal networks are networks like physical contact networks whose topology changes over time. Predicting future temporal network is crucial e.g., to forecast and mitigate the spread of epidemics and misinformation on the network.

Zhang, S. (author), Zhao, Xunyi (author), Wang, H. (author)Progress has been made in how to suppress epidemic spreading on temporal networks via blocking all contacts of targeted nodes or node pairs. In this work, we develop contact blocking strategies that remove a fraction of contacts from a temporal (time evolving) human contact network to mitigate the spread of a Susceptible-Infected-Recovered...journal article 2022

Poenaru-Olaru, L. (author), Redi, Judith (author), Hovanesyan, Artur (author), Wang, H. (author)Small and medium enterprises (SME) are crucial for economy and have a higher exposure rate to default than large corporates. In this work, we address the problem of predicting the default of an SME. Default prediction models typically only consider the previous financial situation of each analysed company. Thus, they do not take into account...conference paper 2022

Tongjing, Wang (author), Meijers, Evert (author), Wang, H. (author)Cities relate to other cities in many ways, and much scholarly effort goes into uncovering those relationships. Building on the principle that strongly related cities will co-occur frequently in texts, we propose a novel method to classify those toponym co-occurrences using a lexicon-based text-mining method. Millions of webpages are analysed...journal article 2022
