Topic Community Based Temporal Expertise for Question Routing
Vaibhav Krishna, Vaiva Vasiliauskaite, Nino Antulov-Fantulin
Question Routing in Community-based Question Answering websites aims at recommending newly posted questions to potential users who are most likely to provide "accepted answers". Mo…
Ensemble approach for generalized network dismantling
Xiao-Long Ren, Nino Antulov-Fantulin
Finding a set of nodes in a network, whose removal fragments the network below some target size at minimal cost is called network dismantling problem and it belongs to the NP-hard…
Sensing Social Media Signals for Cryptocurrency News
Johannes Beck, Roberta Huang, David Lindner +4
The ability to track and monitor relevant and important news in real-time is of crucial interest in multiple industrial sectors. In this work, we focus on the set of cryptocurrency…
Generalized Network Dismantling
Xiao-Long Ren, Niels Gleinig, Dirk Helbing +1
Finding the set of nodes, which removed or (de)activated can stop the spread of (dis)information, contain an epidemic or disrupt the functioning of a corrupt/criminal organization…
Underestimated cost of targeted attacks on complex networks
Xiao-Long Ren, Niels Gleinig, Dijana Tolic +1
The robustness of complex networks under targeted attacks is deeply connected to the resilience of complex systems, i.e., the ability to make appropriate responses to the attacks.…
Simulating SIR processes on networks using weighted shortest paths
Dijana Tolic, Kaj-Kolja Kleineberg, Nino Antulov-Fantulin
We present a framework to simulate SIR processes on networks using weighted shortest paths. Our framework maps the SIR dynamics to weights assigned to the edges of the network, whi…
Modeling peer and external influence in online social networks
Matija Piškorec, Nino Antulov-Fantulin, Iva Miholić +2
Opinion polls mediated through a social network can give us, in addition to usual demographics data like age, gender and geographic location, a friendship structure between voters…
Identification of Patient Zero in Static and Temporal Networks - Robustness and Limitations
Nino Antulov-Fantulin, Alen Lancic, Tomislav Smuc +2
Detection of patient-zero can give new insights to the epidemiologists about the nature of first transmissions into a population. In this paper, we study the statistical inference…
News Cohesiveness: an Indicator of Systemic Risk in Financial Markets
Matija Piškorec, Nino Antulov-Fantulin, Petra Kralj Novak +4
Motivated by recent financial crises significant research efforts have been put into studying contagion effects and herding behaviour in financial markets. Much less has been said…
Statistical inference framework for source detection of contagion processes on arbitrary network structures
Nino Antulov-Fantulin, Alen Lancic, Hrvoje Stefancic +2
In this paper we introduce a statistical inference framework for estimating the contagion source from a partially observed contagion spreading process on an arbitrary network struc…
