Using network motifs to characterize temporal network evolution leading to diffusion inhibition [article]

Soumajyoti Sarkar, Ruocheng Guo, Paulo Shakarian
2019 arXiv   pre-print
In this paper, we use motif patterns to characterize the information diffusion process in social networks.  ...  We test features of motif patterns by using regression models for both individual patterns and their combination and we find that motifs as features are better predictors of the future network organization  ...  Numerous methods have been highlighted in [48] surrounding diffusion models for social networks.  ...

Leveraging Motifs to Model the Temporal Dynamics of Diffusion Networks [article]

Soumajyoti Sarkar, Hamidreza Alvari, Paulo Shakarian
2020 arXiv   pre-print
Information diffusion mechanisms based on social influence models are mainly studied using likelihood of adoption when active neighbors expose a user to a message.  ...  In doing so, we accommodate the effect of exposures from active neighbors of a node through a network pruning technique that leverages network motifs to identify potential infectors responsible for exposures  ...  algorithm based on the learned model Note that some of the patterns contain parallel nodes -one of them denoting a social / historical di usion link apart from the cascade di usion link. ese motifs have  ...

Predictive Analysis for Social Diffusion: The Role of Network Communities [article]

Richard Colbaugh, Kristin Glass
2009 arXiv   pre-print
Of particular interest is the possibility to develop predictive capabilities for social diffusion, for instance enabling early identification of diffusion processes which are likely to become "viral" and  ...  These empirical studies demonstrate that network community-based diffusion metrics do indeed possess predictive power, and in fact can be more useful than standard measures.  ...  In [3] we a present a theoretical analysis of social diffusion on networks with realistic topologies, including community structure. The analysis leverages S-HDS models for network dynamics.  ...

2016 Chaos  
In order to systematically investigate their performance on law activity data, we establish a new stochastic model to generate synthetic law activity data based on plausible networks of interactions.  ...  A universal question in network science entails learning about the topology of interaction from collective dynamics. Here, we address this question by examining diffusion of laws across US states.  ...  Sachit Butail for his constructive feedback and invaluable help during the preparation of the revised version of this work based on the very constructive comments of two anonymous reviewers.  ...

2020 arXiv   pre-print
The popularity of graph neural networks has sparked interest, both in academia and in industry, in developing methods that scale to very large graphs such as Facebook or Twitter social networks.  ...  Our architecture allows using different local graph operators (e.g. motif-induced adjacency matrices or Personalized Page Rank diffusion matrix) to best suit the task at hand.  ...  Studying the effect of operators induced by more complex network motifs is left for future research.  ...

2017 arXiv   pre-print
Using these topics we derive a diffusion network for borrowing from ancestral constitutions back to the US Constitution of 1789 and reveal that constitutions are complex cultural recombinants.  ...  Legal "Ideas" are encoded as "topics" - words statistically linked in documents - derived from topic modeling the corpus of constitutions.  ...  In order to set τ , we varied τ between 0 to 0.8, and inferred the diffusion network for each of the values.  ...

2020 Proceedings of the Twenty-Ninth International Joint Conference on Artificial Intelligence  
Specifically, we propose MTNE, a novel embedding model for temporal networks.  ...  In light of this, we concentrate on a particular motif --- triad --- and its temporal dynamics, to study the temporal network embedding.  ...  According to Eq. (1), we model the triad evolution process by modeling the base rate and past influence, respectively. Base rate.  ...
