Interpreting Graph-based Sybil Detection Methods as Low-Pass Filtering
Satoshi Furutani, Toshiki Shibahara, Mitsuaki Akiyama +1
Online social networks (OSNs) are threatened by Sybil attacks, which create fake accounts (also called Sybils) on OSNs and use them for various malicious activities. Therefore, Syb…
Perturbative expansion of the fundamental equation of online user dynamics for describing changes in eigenfrequencies
Naoki Hirakura, Masaki Aida
The oscillation model has been proposed as a theoretical framework for describing user dynamics in online social networks. This model can model the user dynamics generated by a par…
Derivation and Characteristics of Closed-Form Solutions of the Fundamental Equations for Online User Dynamics
T. Ikeya, Masaki Aida
The oscillation model, based on the wave equation on networks, can describe user dynamics in online social networks. The fundamental equation of user dynamics can be introduced int…
Evaluation of User Dynamics Created by Weak Ties among Divided Communities
Takahiro Kubo, Chisa Takano, Masaki Aida
Flaming phenomena represent the divergence in the strength of user dynamics as created by user interactions in online social networks (OSNs). Although it has been known that flamin…
Increase of Low-Frequency Modes of User Dynamics in Online Social Networks During Overheating of Discussions
Masaki Aida, Koichi Nagatani, Chisa Takano
User dynamics in online social networks have a significant impact on not only the online community but also real-world activities. As examples, we can mention explosive user dynami…
Independence of the Fundamental Equation of the Oscillation Model on Algebraic Representations: Social Media Echo Chamber Effect
Kakeru Ohki, Ayako Hashizume, Masaki Aida
In the oscillation model that describes the user dynamics of online social networks, it is known that the fundamental equation can explicitly describe the causal relationship betwe…
Modeling of Online Echo-Chamber Effect Based on the Concept of Spontaneous Symmetry Breaking
Masaki Aida, Ayako Hashizume
The online echo-chamber effect is a phenomenon in which beliefs that are far from common sense are strengthened within relatively small communities formed within online social netw…
A Model of Polarization on Social Media Caused by Empathy and Repulsion
Naoki Hirakura, Masaki Aida, Konosuke Kawashima
In recent years, the ease with which social media can be accessed has led to the unexpected problem of a shrinkage in information sources. This phenomenon is caused by a system tha…
Technology to Counter Online Flaming Based on the Frequency-Dependent Damping Coefficient in the Oscillation Model
Shinichi Kikuchi, Chisa Takano, Masaki Aida
Online social networks, which are remarkably active, often experience explosive user dynamics such as online flaming, which can significantly impact the real world. However, counte…
A New Model of Flaming Phenomena in Online Social Networks that Considers Resonance Driven by External Stimuli
Tomoya Kinoshita, Masaki Aida
The explosive user dynamics represented by flaming phenomena in online social networks can sometimes negatively influence lives in the real world. To take measures against online f…
Polarization Model of Online Social Networks Based on the Concept of Spontaneous Symmetry Breaking
Masaki Aida, Ayako Hashizume, Chisa Takano +1
The spread of information networks has not only made it easier for people to access a variety of information sources but also greatly enhanced the ability of individuals to dissemi…

Yusuke Sakumoto, Masaki Aida
The spectral graph theory provides an algebraical approach to investigate the characteristics of weighted networks using the eigenvalues and eigenvectors of a matrix (e.g., normali…
On the fundamental equation of user dynamics and the structure of online social networks
Masaki Aida, Chisa Takano, Masaki Ogura
Online social networks suffer from explosive user dynamics such as flaming that can seriously affect social activities in the real world because the dynamics have growth rates that…
Information Propagation Analysis of Social Network Using the Universality of Random Matrix
Yusuke Sakumoto, Tsukasa Kameyama, Chisa Takano +1
Spectral graph theory gives an algebraical approach to analyze the dynamics of a network by using the matrix that represents the network structure. However, it is not easy for soci…
