Information diffusion on realistic networks
نویسندگان
چکیده
Les modèles de diffusion d’information mettent traditionnellement en jeu un réseau sous-jacent dont la topologie reproduit certaines propriétés observées dans les réseaux réels. Toutefois, la comparaison des phénomènes de diffusion observés sur des réseaux générés par des modèles classiques avec ceux se produisant au sein de réseaux réels reste peu étudiée. Dans une démarche empiriste, nous proposons dans cette étude d’évaluer l’écart de comportement induit par l’utilisation de divers modèles stylisés, dont notamment certains réseaux dits “sans-échelle”.

Discovering groups of key potential customers in social networks: A multi-objective optimization model
Nowadays, the popularity of social networks as marketing tools has brought a deal of attention to social networks analysis (SNA). One of the well-known Problems in this field is influence maximization problems which related to flow of information within networks. Although, the problem have been considered by many researchers, the concept behind of this problem has been used less in business con...

A key step for success of marketer is to discover influential users who diffuse information and their followers have interest to this information and increase to diffuse information on social media. They can reduce the cost of advertising, increase sales and maximize diffusion of information. A key problem is how to precisely identify the most influential users on social networks. In this pape...
متن کاملA Fuzzy Realistic Mobility Model for Ad hoc Networks
Realistic mobility models can demonstrate more precise evaluation results because their parameters are closer to the reality. In this paper a realistic Fuzzy Mobility Model has been proposed. This model has rules which are changeable depending on nodes and environmental conditions. It seems that this model is more complete than other mobility models.After simulation, it was found out that not o...
متن کاملControllability of social networks and the strategic use of random information
Background This work is aimed at studying realistic social control strategies for social networks based on the introduction of random information into the state of selected driver agents. Deliberately exposing selected agents to random information is a technique already experimented in recommender systems or search engines, and represents one of the few options for influencing the behavior of a...
متن کاملModeling user and topic interactions in social networks using Hawkes processes
We present in this paper a framework to model information diffusion in social networks based on linear multivariate Hawkes processes. Our model exploits the effective broadcasting times of information by users, which guarantees a more realistic view of the information diffusion process. The proposed model takes into consideration not only interactions between users but also interactions between...
متن کاملImpacts of the Negative-exponential and the K-distribution modeled FSO turbulent links on the theoretical and simulated performance of the distributed diffusion networks
Merging the adaptive networks with the free space optical (FSO) communication technology is a very interesting field of research because by adding the benefits of this technology, the adaptive networks become more efficient, cheap and secure. This is due to the fact that FSO communication uses unregistered visible light bandwidth instead of the overused radio spectrum. However, in spite of all ...
