Le questionnement scientifique qui anime le projet ALGOPOL voudrait comprendre la structure des liens sociaux existant au sein de réseaux égocentrés à partir du contenu des échanges et des liens partagés sur Facebook. Les interactions sur cette plateforme se déploient-elles différemment, avec une énonciation différente, autour de contenus partagés différents, selon les segments du réseau social mobilisés ? A-t-on des conversations différentes avec les liens « forts » et les liens « faibles » ? Les objets informationnels mis en partage sont-ils les mêmes selon la forme et la structure de la sociabilité numérique des individus ? Chercher à répondre à ces questions requiert des données fines et précises que les méthodes d’enquête traditionnelle ont beaucoup de difficulté à fournir [11].

How To Detect #Communities Using Social Network Analysis | #SNA | e-Xploration | Scoop.it
luiy's insight:

Think of communities as very similar to the segments identified in a brand’s customer segmentation model. (With demographics analysis layered on, you might even find that they’re the same.)

While direct marketing communications is often customized by segment, historically this hasn’t been something brands have done in social. But, using social network analysis and also Twitter & Facebook ad targeting, it’s possible to send specific messages to specific groups of people.

 

Powered by Pulsar TRAC these could be people engaging in a specific conversation, individuals sharing a piece of content online, or the followers of an account on Twitter. Any group of people, in essence, as long as we can define that audience through some property of its behaviour in social media – such as keyword, user bio, or location.

 

Community analysis allows brands to really understand the behavior of their audiences in a way they can’t replicate with offline, non-social data.

L’application Algopol vous permet de visualiser et d’explorer votre réseau d’amis Facebook I #dataviz

L’application Algopol vous permet de visualiser et d’explorer votre réseau d’amis Facebook I #dataviz | e-Xploration | Scoop.it
L'application Algopol vous permet de visualiser et d'explorer votre réseau d'amis Facebook en fonction de l'histoire de votre compte et des interactions avec vos amis (likes, commentaires).
luiy's insight:

Déroulement de l'enquête

La mise en place de l’application se déroule en 3 étapes.

 

1 - Accord pour participer à l’enquête

A cette étape, il vous est demandé de prendre connaissance des conditions d’utilisation de l’application, et de donner votre accord pour participer à l’enquête.

 

2 - Collecte et description des informations

A partir de votre accord, l’application vous demande de vous connecter sur Facebook, et vous propose de paramétrer l’application. Nous ne collectons pas votre mot de passe Facebook. Le navigateur sera connecté à votre compte Facebook tant que vous serez connecté à l'application. Nous ne publions rien en votre nom sur votre mur Facebook, sauf si vous souhaitez que nous informions vos amis de votre participation à l’enquête, ou que nous publiions la carte de votre réseau. Une fois que vous êtes authentifié, l’application va collecter votre profil Facebook, le profil de vos amis, et votre activité (statut, like, commentaire). Cette collecte peut prendre plusieurs minutes.

En parallèle de la collecte, nous vous demanderons de répondre à trois questions sur vous, puis à cinq questions sur cinq de vos amis.

 

3 - Exploration du réseau social

L’application affiche une page avec la cartographie de votre réseau d’amis : il s’agit d’une carte où chaque point est un de vos amis, les liens entre les points signifient que vos amis se connaissent, et le regroupement des amis se fait en fonction du nombre de liens entre eux. Vous n’êtes pas sur la carte, puisque vous connaissez tout le monde ! Vous pouvez:

zoomer, dézoomer, déplacer la carte avec votre souris pour voir plus précisément vos amis;paramétrer l'affichage de la couleur et la taille des points de votre réseau avec le menu à droite de la carte;faire bouger la période d'observation avec la timeline en bas de la carte, et retrouver ainsi le début de votre Facebook;rechercher dans vos statuts ceux qui sont les plus populaires avec l'onglet en haut à droite du paramétragedécrire vos amis pour une meilleure analyse

Pour voir toutes les fonctionnalités possibles de l’exploration, référez-vous à la page FAQ et au mode d'emploi

Pour sortir de l’application, vous pouvez vous déconnecter en utilisant le bouton en haut à droite de l'écran.

 

L’application Algopol est un protocole expérimental qui peut avoir des bugs : merci de nous remonter toute question, anomalie, ou remarque soit par email à contact@app.algopol.fr, soit sur notre page Facebook.

Industrializing Personal Data Production (First Monday)


Via Pierre Levy
luiy's insight:

Free trade and free speech: the Internet ideal

Facebook text didn’t just arrive on our screens; rather, it echoes key discourses embedded in abstractions offered by other monopoly new media dominating our desktops. It developed, built upon and extended a set of pre–existing structures hardcoded in online globally consumed interfaces, referred to here as “the Web’s commercial interface” (Patelis, 2010). The Web’s commercial interface, of which Facebook is now an integral part, lies at centre stage of the online of experience of a majority of users in the West. Its properties cannot be exhausted within the confines of this paper.

Instead we wish to focus on a key component crucial to Facebook: the integration of commerce and communication. The Internet mediates the integration of commerce and communication, unifying and demanding the synchronous development and integration of very dissimilar services and by extension objects. In other words, at the heart of text offered by monopoly new media software, lies the liberal ideal according to which commerce and communication can and should be integrated online, the idea that free speech and free trade are two sides of the same coin and that, by extension, online commerce and online communication are complementary ideals in the democratic capitalist ideal. In representational terms, such integration is so naturalised that a kilo of potatoes for sale and an opinion on paedophilia are literally represented as similar objects across outlets. To quote Bill Gates from 1996:

 

“Capitalism, demonstrably the greatest of the constructed economic systems, has in the past decade clearly proved its advantages over the alternative systems, As the Internet evolves into its broadband, global interactive network, those advantages will be magnified. Product and service providers will see what buyers want a lot more efficiently than ever before and consumers will buy more efficiently. I think Adam Smith would be pleased.” [2]

 

We argue that Facebook has been central to the further restructuring and commodification of the media industry around this ideal by establishing further integration of commerce and communication in two ways. Firstly, through the demonization of anonymity and secondly, through the industrialisation of the production of personal data. Coupled with Facebook’s endeavour to colonise the Web, this restructuring has taken centre stage in the development of the media industry recently. Facebook text is key to understanding the broader standardization process of communication on the Web, mainly because it demands user participation in the production process and naturalizes the commodification and industrialisation of personal data. Personalization is a large part of communication in Facebook to the point that personalization — and hence standardization — constitute the product. Thus, individualized information is less important than the fact that information will be archived and ‘pprocessed’, with more personal data produced as a result. This processing allows Facebook to industrialise the production of data.

Pierre Levy's curator insight, March 12, 2013 1:13 PM

This article examines Facebook.com as a cultural text. It casts a critical eye on the stories told by the Facebook monopoly interphase, focusing on how these intergrate commerce with communications. It struggles with the text’s key abstractions arguing that Facebook industrialises personalised data production by demanding the constant production on customised communcation objects.

Your Digital Image: Factors Behind #Demographic and #Psychometric #Predictions from Social Network Profiles |  #identity | e-Xploration | Scoop.it
luiy's insight:

Our system allows users to examine the factors influencing the predictions, so users can determine how “Liking” a certain item changes the predictions regarding their intel ligence, or how changing the number of friends they have affects the predictions regarding their personality. Clearly, these factors are under the control of the user, and users may modify their behavior on Facebook to be perceived in a positive manner. As people can form judgments on others based on their social media profiles [4], this phenomenon is not new. However, we believe an automated tool can allow people to easily determine how others may perceive thembased on their behavior on social networks.

How People Consume #Conspiracy Theories on Facebook | #sna #controverses

How People Consume #Conspiracy Theories on Facebook | #sna #controverses | e-Xploration | Scoop.it
… in much the same way as mainstream readers consume ordinary news, say computer scientists.
luiy's insight:

And that raises an interesting question. How do conspiracy theories spread through the Internet and do people treat these ideas in a way that is fundamentally different to conventional stories from established news organizations?

 

To find out, Alessandro Bessi and pals at the Institute for Advanced Studies in Lucca, Italy, examined the way people on Facebook consume conspiracy theories versus the way they consume mainstream news. And they say there are remarkable similarities but also some interesting differences that may help to better understand the way that false information spreads around the web.

 

The team began by studying over 270,000 posts created on 73 different Facebook pages. They classified these pages according to the kind of information they contained, whether conspiracy news or mainstream scientific news. They also counted the number of likes each post received, a total of almost 10 million, the number of shares, as well as the individuals who contributed.

 

Having divided up the posts, they found that around 60,000 involved mainstream scientific news and over 200,000 involved alternative conspiracy news. And while the scientific news received 2.5 million likes, the alternative news had over 6.5 million likes.

Paul Butler – Visualizing Facebook Friends: #EyeCandy in #R I #dataviz

Paul Butler – Visualizing Facebook Friends: #EyeCandy in #R I #dataviz | e-Xploration | Scoop.it
luiy's insight:

I’ve received a lot comments about the image, many asking for more details on how I created it. When I tell people I used R, the reaction I get is roughly what I would expect if I told them I made it with Microsoft Paintand a bottle of Jägermeister. Some people even questioned whether it was actually done in R. The truth is, aside from the addition of the logo and date text, the image was produced entirely with about 150 lines of R code with no external dependencies. In the process I learned a few things about creating nice-looking graphs in R.

 

Transparency and Faking It

My first attempt at plotting the data involved plotting very transparent lines. Unfortunately there was just too much data to get a meaningful plot — even at very low opacity, there were enough lines to make the entire image just a bright blob. When I increased the transparency more, the opacity was rounded down to zero by my graphics device and the result was that nothing was drawn.

The solution was to manipulate the drawing order of the lines. I used a simple loop over my data to draw the lines, so it was easy to control which lines are drawn first using order(). I created an ordering based on the length of the lines, so that longer lines were drawn “behind” the shorter, more local lines. Then I used colorRampPalette() to generate a color palette from black to blue to white, and colored the lines according to order they were drawn.

luiy's insight:
But sharing can be exhausting. You hear about people taking “Facebook vacations.” It’s an interesting phenomenon. We have two ways to turn off Facebook: deactivate and delete. The group who chooses to turn Facebook off permanently is relatively small, but there’s a larger set of people who will deactivate their account for a day or two because they want to focus and study for a test—it’s the equivalent of locking yourself in the library. It’s actually a very popular feature. Did you ever take a Facebook vacation? I don’t think I ever have. I certainly turn off my phone from time to time. Changes made to Facebook used to reliably draw outrage, especially over privacy concerns. But when you announced Graph Search, which allows users to find more personal information shared by their friends, there wasn’t much of an outcry. What have you learned? One of the things we did a lot better this time is we talked to a lot of folks to understand the concerns of organizations and others. Typically we have an iterative approach, but here we felt, in terms of privacy, everything had to be there at the beginning. The project was actually ready to go in December, but we took an extra month to build more privacy tools. You say Facebook follows “the Hacker Way.” How is it core to what happens here? It really is our philosophy for how we build stuff. There are a bunch of companies that try to make every release perfect, and Apple is the best at that. That’s wonderful, but there’s another way of doing things that’s potentially even better over the long term—allow yourself room to experiment and don’t try to make each individual release as polished as possible. You’re not yet 30 and you’ve begun to make some significant charitable contributions. What’s your thinking on this? Bill Gates offered me some advice: Don’t just give your money away—it’s something that requires practice to get good at. So why wait? Clearly I have a day job that takes up 99 percent of my time, so I can’t be running a foundation. But I can take a venture capital approach, where you invest in people. I made the investment in Newark schools because I really believed in the governor and mayor over there, and they’ve delivered.

Facebook's Graph Search worries security experts

Facebook's Graph Search worries security experts | e-Xploration | Scoop.it
Post highlighting embarrassing things raises questions of user privacy with Graph Search, which Facebook users cannot opt out of

 

Facebook believes its responsibility is to provide the privacy settings, while users are responsible for using them. "You control who you share your interests and likes with on Facebook," the company said Thursday in an emailed statement.

 

When joining Facebook, people trade their personal information for free use of the social network. Given that, security experts agree that people are responsible for controlling who sees that information.

 

However, some experts believe Facebook does not go far enough in educating users about the potential threats in keeping information public. Because Graph Search makes all that personal information easily searchable, education on its dangers should be a much higher priority for Facebook.

 

===> "Some people do not grasp the importance of Graph Search," said Bogdon Botezatu, a senior e-threat analyst for Bitdefender. "So maybe it would be better for Facebook to actually inform people that some things will change." <===
