Integrating threshold models with Markov chains for information diffusion in social networks

In this paper, I introduce an agent-based approach that leverages Markov models to formalize and understand information propagation within social networks. This methodology aims to explain the internal information states of agents and employs probabilistic model checking to analyze these models. Initially, I provide a comprehensive overview of the current research on information diffusion in social networks. Following this, I delve into the fundamentals of model checking and illustrate how this technique can be used to assess model accuracy, particularly in managing large networks with high precision. To demonstrate the effectiveness of this approach, I conduct a series of experiments. The results show that this paper provides a robust and effective method for analyzing complex information diffusion and network behavior.

PHYSICAL ANALYSIS OF SOCIAL DYNAMICS: A SOCIOPHYSICS PERSPECTIVE

Sociophysics is an interdisciplinary field that uses methods from the physical sciences to study human behavior and interactions. It includes mathematical and computational techniques such as big data analysis, statistical modeling, network theory, and simulations. It analyzes complex systems to understand the dynamics of society. Historically, sociophysics emerged from applying statistical mechanics and thermodynamics to social phenomena. Foundational work has modeled opinion dynamics, crowd behavior, and information diffusion in social networks, and provided insights into consensus, polarization, and social stability. The basic concepts are based on treating individuals as agents, using network theory, and applying statistical mechanics and dynamical systems. Methods include big data analysis, statistical modeling, simulations, and network analysis. Future research will aim to integrate artificial intelligence and machine learning, foster interdisciplinary collaboration, utilize real-time data, and apply findings to public policy. Sociophysics aims to improve our understanding of social systems and solve today's society's complex problems. In this study, the field of sociophysics, its historical development, studies in the literature, and methods were generally discussed.

Modeling Group Opinion Evolution on Online Social Networks: A Gravitational Field Perspective

The research on group behavior is effective for establishing a good network environment since people in social networks tend to form groups spontaneously. Most studies on group behavior on online social networks assume that all individuals are reduced to one cluster, ignoring the existence of potential clusters and their importance in group opinion dynamics. This article introduces a novel group-gravitational field (GGF) model to investigate the opinion evolution based on group behavior by the following aspects: 1) the GGF model reduces a cluster in the social network into a charge and the whole network into a gravitational field; 2) the GGF model calculates the initial influence of a cluster according to the topology information and further constructs a gravity matrix of the network based on the Coulomb law; and 3) opinion-leader clusters exert the internal field force on common opinion clusters inside the gravitational field. The GGF model simulates the evolution of opinions among clusters in a network and studies the law of group behavior according to the influence between clusters based on Coulomb’s law. Experiments on real social networks verify that the GGF model enhances the speed of opinion evolution significantly. The simulation experiments indicate that the existence of clusters promotes the rapid convergence of opinions, a gathering of followers influences information dissemination in social networks, and the GGF model fits the reality better. This article provides a new approach to network supervision and control.

Optimization of network flows for rural extension of fruit and vegetable agricultural technologies

Abstract This paper focuses on the rural promotion of fruit and vegetable agricultural technology and proposes a network flow optimization model based on linear programming for the diffusion of fruit and vegetable agricultural technology. Based on the Bass model, it describes the process of natural growth of network users and the word-of-mouth effect among them. Fruit and vegetable agricultural technology diffusion in real social networks is fitted and predicted by the social network information dissemination model, and the network flow problem of fruit and vegetable agricultural technology promotion is optimized using linear programming equations. Based on this basis, the algorithm designed in this paper and the effect of rural promotion of fruit and vegetable agricultural technology are analyzed with relevant data. The results show that the coefficient of the variable of the number of promotion times in the behavior of agrotechnology promotion is 0.064, which has a significant positive effect on the evaluation of the rural promotion performance of fruit and vegetable agricultural technology, indicating that increasing the number of agricultural technology training and enriching the content of agricultural technology promotion will help to improve the evaluation of the rural promotion performance of fruit and vegetable agricultural technology by farmers. The network flow optimization model constructed in this paper can enable farmers to master more modern fruit and vegetable agricultural technology to meet the needs of modern production of fruit and vegetable agriculture so as to improve the level of local fruit and vegetable agricultural development.

The dynamic coupling mechanism of information and epidemic propagations considering individual mobility in two-layer network framework

The epidemic had taken massive hurt on human beings for their lethal viruses and rapid spread, such as the outbreak of Corona Virus Disease 2019 (Covid-19). How to control the virus spreading came to be a tough question and drew a lot of research attentions at that time. By the empirical data analysis from Shanghai China, we find information diffusion is co-evolving with epidemic spread, and vice versa. In order to reveal the coupling mechanism of epidemic spread and information diffusion, or the influencing factors on epidemic spread, we present a two-layer network framework to investigate the coupling mechanism of information diffusion and epidemic spread, and discuss the influencing factors. Thus, from the perspective of considering individual behaviors (such as individual mobility), a coupling propagation model of information diffusion and epidemic spread in two-layer network framework is proposed by dynamic equations. With the theoretical and numerical analysis, it is found epidemic spread might be influenced by epidemic itself mechanism and individual mobility indicated by mobility frequency and range to a certain extent from the micro perspective. Moreover, the role of individual mobility in promoting or delaying epidemic spread depends on the distribution of epidemic network. While from the macro perspective, it is found that promoting information diffusion in social networks could reduce the epidemic spread scales effectively by calculating the epidemic threshold and comparing with Monte Carlo (MC) simulation experiments. In addition, the global control strength from government or social organizations is also a key factor for reducing epidemic spread. Results in this work provide some reasonable and practical strategies for management on epidemic prevention and control in future.

An Extension of the Susceptible–Infected Model and Its Application to the Analysis of Information Dissemination in Social Networks

Social media significantly influences business, politics, and society. Easy access and interaction among users allow information to spread rapidly across social networks. Understanding how information is disseminated through these new publishing methods is crucial for political and marketing purposes. However, modeling and predicting information diffusion is challenging due to the complex interactions between network users. This study proposes an analytical approach based on diffusion models to predict the number of social media users engaging in discussions on a topic. We develop a modified version of the susceptible–infected (SI) model that considers the heterogeneity of interactions between users in complex networks. Our model considers the network structure, abandons the assumption of homogeneous mixing, and focuses on information diffusion in scale-free networks. We provide explicit algorithms for modeling information propagation on different types of random graphs and real network structures. We compare our model with alternative approaches, both those considering network structure and those that do not. The accuracy of our model in predicting the number of informed nodes in simulated information diffusion networks demonstrates its effectiveness in describing and predicting information dissemination in social networks. This study highlights the potential of graph-based epidemic models in analyzing online discussion topics and understanding other phenomena spreading on social networks.

CTL-DIFF: Control Information Diffusion in Social Network by Structure Optimization

A critical side effect of online social networks' flourishing is fast-spreading rumors on the Internet, making the information diffusion control on social networks a fundamental requirement. While information diffusion control has received extensive attention at the global level, there have been fewer user-level diffusion control studies under minimal budget. In this article, we study the information diffusion at the user level and propose a diffusion control method based on gradient information to generate an optimized network structure, namely ConTroL information DIFFusion (CTL-DIFF). CTL-DIFF targets a user through subtle modifications of its local network structure. It first selects the edges with the largest absolute gradient based on the prediction model to optimize the original network's structure. It then employs several prediction methods to verify whether the target user's social action status is controlled. CTL-DIFF achieves state-of-the-art control performance with a minimum budget, comparing with five baselines based on edge centrality strategies on four real-world datasets. We extend the diffusion control from user-level to global-level, comparing with four baselines on three datasets. Experimental results show that CTL-DIFF can effectively control information diffusion in the global social network by identifying and controlling the most influential users.

Integrating Multiple Linear Regression and Infectious Disease Models for Predicting Information Dissemination in Social Networks

Social network is the mainstream medium of current information dissemination, and it is particularly important to accurately predict its propagation law. In this paper, we introduce a social network propagation model integrating multiple linear regression and infectious disease model. Firstly, we proposed the features that affect social network communication from three dimensions. Then, we predicted the node influence via multiple linear regression. Lastly, we used the node influence as the state transition of the infectious disease model to predict the trend of information dissemination in social networks. The experimental results on a real social network dataset showed that the prediction results of the model are consistent with the actual information dissemination trends.

Analysis on the differences in information dissemination laws between online and offline social networks

Social networks are ubiquitous, which has been one of the important topics of many scholars. With the rapid development of information technology in recent years, people's social platforms are not limited to offline, and online social networks have gradually become an indispensable part of our lives. However, there is still a lack of research on the differences between online and offline social networks. Therefore, this paper probes into the differences between online and offline social network information dissemination by collecting data from online and offline double-layer coupled networks, and comparing and analyzing the data. Research shows that there are some differences between online and offline social networks in the law of information dissemination, which will have a certain impact on real life. Therefore, three suggestions are put forward: 1. At the initial stage of promotion, there are few audience groups, so offline methods can be adopted. With the expansion of information dissemination scope, gradually turning to online promotion, the best promotion effect will be achieved at the fastest speed. 2. The speed and effect of information dissemination can't be ignored for people who have no value in social network information dissemination. 3. Based on the complexity of the public opinion information dissemination network, users need to constantly cultivate their ability to identify information, the management of major social platforms earnestly perform their regulatory responsibilities, and the relevant functional departments of the government gradually establish a public opinion guidance mechanism. If joint efforts can be formed, the public opinion prevention and control effect will be more significant.

PROTECTION OF HUMAN HONOUR AND DIGNITY IN SOCIAL NETWORKS: PROBLEMS AND POSSIBLE SOLUTIONS

This article is devoted to the analysis of the problems of protecting human honour and dignity in social networks. The article reveals three problems on the subject of the study – the widespread use of social networks, virtually unlimited freedom of information dissemination in social networks, as well as the latency of offenses committed in the virtual space. Based on the analysis of the reasons and opinions of some scientists, the author of the article proposes to implement measures in four directions – i) the formation of reasonable legal regulation, ii) strengthening international cooperation, iii) taking organizational and technical measures, iv) increasing the level of legal culture and ethics in social networks. Based on the results of the article, the author concludes that the legal regulation of social networks for the protection of human honour and dignity should be as specific and sufficient as possible.

Representation Learning Method Based on Improved Random Walk for Influence Maximization

The purpose of the influence maximization problem is to determine a subset to maximize the number of affected users. This problem is very crucial for information dissemination in social networks. Most traditional influence maximization methods usually focus too heavily on the information diffusion model and randomly set influence parameters, resulting in inaccurate final outcomes. Driven by the recent criticisms of the diffusion model and the rapid development of representation learning, this paper proposes a representation learning method based on improved random walk for influence maximization (IRWIM) to maximize the influence spread. The IRWIM algorithm improves the traditional random walk and adopts multi-task neural network architecture to predict the propagation ability of nodes more accurately. Moreover, the greedy strategy is utilized to continuously optimize the marginal gain while retaining the theoretical guarantee. IRWIM is tested on four genuine datasets. Experimental results show that the accuracy of the proposed algorithm is superior to various competitive algorithms in the field of influence maximization.

The effect of opinion emotion on information dissemination in social networks

When popular topics arise, Internet users typically share their opinions and interact with others on social networking platforms, and the comments generated on social networks contribute to the spread of popular trends. In this paper, we focus on the popular ChatGPT topic and analyze the evolutionary trend of public opinion and the emotional polarity of comments related to ChatGPT on the Weibo and WeChat social media platforms. In this paper, emotions are divided into six categories, the emotions contained in Weibo and WeChat comments are discussed, and the main opinions reflected in each emotion are examined. We expect that our finding will help reveal the relationship between opinion and sentiment.

Network distribution and sentiment interaction: Information diffusion mechanisms between social bots and human users on social media

When public health emergencies occur, a large amount of low-credibility information is widely disseminated by social bots, and public sentiment is easily manipulated by social bots, which may pose a potential threat to the public opinion ecology of social media. Therefore, exploring how social bots affect the mechanism of information diffusion in social networks is a key strategy for network governance. This study combines machine learning methods and causal regression methods to explore how social bots influence information diffusion in social networks with theoretical support. Specifically, combining stakeholder perspective and emotional contagion theory, we proposed several questions and hypotheses to investigate the influence of social bots. Then, the study obtained 144,314 pieces of public opinion data related to COVID-19 in J city from March 1, 2022, to April 18, 2022, on Weibo, and selected 185,782 pieces of data related to the outbreak of COVID-19 in X city from December 9, 2021, to January 10, 2022, as supplement and verification. A comparative analysis of different data sets revealed the following findings. Firstly, through the STM topic model, it is found that some topics posted by social bots are significantly different from those posted by humans, and social bots play an important role in certain topics. Secondly, based on regression analysis, the study found that social bots tend to transmit information with negative sentiments more than positive sentiments. Thirdly, the study verifies the specific distribution of social bots in sentimental transmission through network analysis and finds that social bots are weaker than human users in the ability to spread negative sentiments. Finally, the Granger causality test is used to confirm that the sentiments of humans and bots can predict each other in time series. The results provide practical suggestions for emergency management under sudden public opinion and provide a useful reference for the identification and analysis of social bots, which is conducive to the maintenance of network security and the stability of social order.

Predicting opinion evolution based on information diffusion in social networks using a hybrid fuzzy based approach.

Social media plays an important role in disseminating information and analysing public and government opinions. The vast majority of previous research has examined information diffusion and opinion analysis separately. This study proposes a new framework for analysing both information diffusion and opinion evolution. The change in opinion over time is known as opinion evolution. To propose a new model for predicting information diffusion and opinion analysis in social media, a forest fire algorithm, cuckoo search, and fuzzy c-means clustering are used. The forest fire algorithm is used to determine the diffuser and non-diffuser of information in social networks, and fuzzy c-means clustering with the cuckoo search optimization algorithm is proposed to cluster Twitter content into various opinion categories and to determine opinion change. On different Twitter data sets, the proposed model outperformed the existing methods in terms of precision, recall, and accuracy.

An approach to detect backbones of information diffusers among different communities of a social platform

Information diffusion in social networks is a classic and, at the same time, very current problem. In fact, information diffusers are always looking for new techniques to disseminate information of their interest by creating backbones among them. In this paper, we focus on a specific, but very current and relevant, scenario regarding this way of proceeding. In fact, we propose an approach for the detection of possible backbones of information diffusers among different communities of a social network. Our approach is based on a new centrality measure that we call disseminator centrality. It is specifically designed to detect the so-called disseminator bridges, i.e., users belonging to multiple communities of a single social network, who want to disseminate information of their interest from one community to another by supporting each other. This paper describes the proposed approach, presents the disseminator centrality, illustrates the differences with respect to the related literature and presents the results of the experiments carried out to evaluate its performance.

Controlling the Spread of Two Secrets in Diverse Social Networks (Student Abstract)

Information diffusion in social networks is a well-studied concept in social choice theory. We propose the study of the diffusion of two secrets in a heterogeneous environment from the complexity perspective, that is, there are two different networks with the same set of agents (e.g., the structure of the set of followers might be different in two distinct social networks). Formally, our model combines two group identification processes for which we do have independent desiderata---either constructive, where we would like a given group of agents to be exposed to a secret, or destructive, where a given group of agents should not be exposed to a secret. To be able to reach these targets, we can either delete an agent or introduce a previously latent agent. Our results are mostly negative---all of the problems are NP-hard. Therefore, we propose a parameterized study with respect to the natural parameters, the number of influenced agents, the size of the required/protected agent sets, and the duration of the diffusion process. Most of the studied problems remain W[1]-hard even for a combination of these parameters. We complement these results with nearly optimal XP algorithms.

Posters and protesters

Do social media incite protest movements, how? How does onsite protest shape online communication dynamics on social media? We examine the oft-debated relationship between social media activity and protest, considering the Yellow Vests or Gilets Jaunes movement in France. We use data of temporal and spatial distribution of Facebook activity and onsite events over a year of social mobilization to address these questions within a system of interacting online and offline activity. This study contrasts with others by analyzing mutual influences between online and offline domains while considering collective information diffusion in social networks. The results show that the relationship between social media activity and onsite protests is not constant nor one-sided, but mutual, and that it changes over the course of the collective action in specific and measurable ways. Using online and offline data, we show different mechanisms by which both domains of activity influence each other. Specifically, the creation of Facebook groups impacts the outbreak of protests, and in turn, this outbreak modifies the parameters of information diffusion between users on Facebook. In addition, Facebook content that pertains to the frames of the movement and mobilization affects onsite mobilization efforts. Our work contributes to the modeling of social movements as systems of online and offline events, expanding on studies that traditionally examine the impact of online activity over onsite protest.
