An approach for influence estimatation in complex networks : application to the social network Twitter
2019
Influence in complex networks and in particular Twitter has become recently a hot research topic. Detecting most influential users leads to reach a large-scale information diffusion area at low cost, something very useful in marketing or political campaigns. In this thesis, we propose a new approach that considers the several relations between users in order to assess influence in complex networks such as Twitter. We model Twitter as a multiplex heterogeneous network where users, tweets and objects are represented by nodes, and links model the different relations between them (e.g., retweets, mentions, and replies).The multiplex PageRank is applied to data from two datasets in the political…
Towards better privacy preservation by detecting personal events in photos shared within online social networks
2015
Today, social networking has considerably changed why people are taking pictures all the time everywhere they go. More than 500 million photos are uploaded and shared every day, along with more than 200 hours of videos every minute. More particularly, with the ubiquity of smartphones, social network users are now taking photos of events in their lives, travels, experiences, etc. and instantly uploading them online. Such public data sharing puts at risk the users’ privacy and expose them to a surveillance that is growing at a very rapid rate. Furthermore, new techniques are used today to extract publicly shared data and combine it with other data in ways never before thought possible. Howeve…

Facebookland: o mundo bizarro-linguístico
2019
Abstract This article investigates the dynamics of contemporary Romanian, focusing on various linguistic structures typically used on social network sites, through which the specific content and interaction strategies are being deployed in virtual communities. The article is part of a larger project devoted to the study of linguistic impoverishment (affecting both the vocabulary and the grammatical structure of the language), social networks being only one of the areas where these “uglified” linguistic structures come from: the mass-media (both print and broadcast), advertising (outdoor, indoor, television commercials), Internet forums, corporate jargon, etc. The structures under scrutiny a…
From the mouth to digital spaces : mediatization and spectacularization of the political “petites phrases”
2023
The political “petites phrases” seems to occupy a growing place in the newspapers and social media. The development of web 2.0 and digital social networks have boosted this political-media phenomenon that was born in the 1970s, thanks to new formats of televised debates. Our study, based on the initial work of Krieg-Planque (2011) and Maingueneau (2012), aims to analyse specific processes and devices accompanying the reproduction of these fragments of political speech on digital social networks. To this end, we will return to the way in which “petites phrases” are detached and put into circulation, as well as to the media devices aimed at putting into spectacle and reinforcing their polemic…

The majorityof websites is now dedicated to social interactions of their users, or offerstools to develop these interactions. Our work focuses on the understanding of theseexchanges, as well as emerging community structures arising, through a semanticapproach. To meet the needs of web analysts, we analyze these community structuresto identify their essential characteristics as their thematic centers and centralcontributors. Our semantic analysis is mainly based on reference light ontologiesto define several new metrics such as the temporal semantic…

What kind of ICT devices should allows inhabitants of the Fontaine D'ouche area to be more resilient? In this case, how …
