A Real-World Spreading Experiment in the Blogosphere

Adrien Friggeri, Jean-Philippe Cointet and Matthieu Latapy

We designed an experiment to observe a spreading phenomenon in the blogosphere. This experiment relies on a small applet that participants copy on their own web page. We present the obtained dataset, which we freely provide for study, and conduct basic analysis. We conclude that, despite the classical assumption, in this experiment famous blogs do not necessarily act as super spreaders.

Spreading of a file in a P2P system

Spreading of a file in a P2P system

> By Matthieu Latapy and Abdelhamid Salah Brahim Download In a peer-to-peer (P2P) file exchange system, there is no central server that would store all available files and distribute them to users. Instead, the system self-organises in a way such that exchanges occur directly between users, between peers. Here we represent the spreading of a […]

Direct and indirect influence of blogs

Direct and indirect influence of blogs

> By Matthieu Latapy, Jean-Philippe Cointet and Adrien Friggeri The study of information diffusion among individuals in a social network is a challenging task as there are different possible definitions for a given concept. Consider for example a blogger who publishes a piece of information on his website; there are mainly two ways of quantifying […]

Files diffusion in a edonkey P2P system

Files diffusion in a edonkey P2P system

> By Abdelhamid Salah Brahim, Bénédicte Le Grand and Matthieu Latapy In the paper Ten Weeks in the Life of an eDonkey Server we present the capture of exchanges between a large eDonkey server and its clients during ten weeks in continuous, leading to the observation of approximately 80 million distinct clients and 275 million […]

Download history of popular files

Download history of popular files

> By Frédéric Aidouni and Matthieu Latapy This plot shows the time-evolution of the number of peers which have downloaded three specific files (one color per file) in a P2P system, as observed during a 10 weeks continuous measurement. We selected three files which have been downloaded many times but did not appear during the […]

Spreading of the Happy Flu experiment

Spreading of the Happy Flu experiment

> By Matthieu Latapy, Adrien Friggeri and Jean-Philippe Cointet Download The Happy Flu experiment aims at observing how an information may spread among web pages. It proposes to anyone who encounters the experiment on a web page he/she visits to participate. The experiment then becomes visible from his/her own page. We then register the date […]

Dynamics of three-state excitable units on Poisson vs power-law random networks

Anne-Ruxandra Carvunis, Matthieu Latapy, Annick Lesne, Clémence Magnien and Laurent Pezard

The influence of the network topology on the dynamics of systems of coupled excitable units is studied numerically and demonstrates a lower dynamical variability for power-law networks than for Poisson ones. This effect which reflects a robust collective excitable behavior is however lower than that observed for diffusion processes or network robustness. Instead, the presence (and number) of triangles and larger loops in the networks appears as a parameter with strong influence on the considered dynamics.
