Fake online identities... "A hard act to Swallow"


Via Pierre Levy
luiy's insight:

The case of Santiago Swallow is intriguing. Swallow was born in Mexico, took up residence in the USA, and rapidly rose to prominence as a respected and influential guru in the world of social media. Now 42, Swallow is a veteran of the TED and SXSW conference circuit, and regularly tweets out his wisdom and insight to more than 76,000 Twitter followers. His recent nuggets have included: 'The first cloud computer was us' and 'to write is to live endlessly'.  Swallow's eagerly awaited book - entitled Imaginary Identities in the Age of the Internet - has been predicted to have such impact potential that it will define an entire generation. Indeed, Swallow has been hailed by some commentators as 'one of the greatest thinkers of the Millennial Generation'.

So just who is Santiago Swallow?

The answer, surprisingly for his many followers, is that Santiago Swallow doesn't actually exist - he is in fact a fictional character. Swallow is the alter ego of Kevin Ashton, a British technology pioneer who is famous for coining the phrase 'the Internet of Things.' If you search on Wikipedia for Santiago Swallow right now, you will be redirected to Ashton's page. The whole Swallow charade was concocted as a social experiment, a way of exploring how many people online create their own legends, often by buying Twitter followers, creating false email accounts and generally masquerading as someone else.  It was easy to create the legend of Santiago Swallow, Ashton says in his blogpost 'How to Become Internet Famous for $68'. He first created a new gmail account, and then a Twitter account.The next stage was to acquire 90,000 Twitter followers for a small sum of about £33. A Wikipedia page was created, and the final step was to construct a Swallow website with its own domain name for another £12. Others soon noticed Swallow's presence and started to follow, assuming that he was indeed who he said he was. This fascinating social online experiment has revealed how easy it is to fake an identity, or in this case, simply create a new one from nothing but a germ of an idea.

Popularity Prediction in Microblogging Network: A Case Study on Sina Weibo

ukituki's curator insight, April 17, 2013 9:02 AM

Predicting the popularity of content is important for both the host and users of social media sites. The challenge of this problem comes from the inequality of the popularity of con- tent. Existing methods for popularity prediction are mainly based on the quality of content, the interface of social media site to highlight contents, and the collective behavior of user- s. However, little attention is paid to the structural charac- teristics of the networks spanned by early adopters, i.e., the users who view or forward the content in the early stage of content dissemination.

 

In this paper, taking the Sina Weibo as a case, we empirically study whether structural character- istics can provide clues for the popularity of short messages. We find that the popularity of content is well reflected by the structural diversity of the early adopters. Experimental results demonstrate that the prediction accuracy is signif- icantly improved by incorporating the factor of structural diversity into existing methods

luiy's insight:

CREATING YOUR "WEB REPUTATION"

The Whuffie Bank, for example, is a nonprofit organization dedicated to building a new currency based on reputation that can be redeemed for real and virtual products and services. The term whuffie was coined by Cory Doctorow, a science fiction writer, to denote a unit of reputation-based currency in his novel Down and Out in the Magic Kingdom. The Whuffie Bank issues whuffies based on a reputation algorithm that blends information from different social networks. It aims to build a platform that measures the online reputation of contributors on various sites. “As we develop and refine the algorithm that tracks public user activity over the net, the whuffie will become an accurate reflection of your web reputation,” the site (currently offline) explains. “And as the Internet and social networks become a large part of people’s lives, your web influence will become an increasingly accurate reflection of you.”

 

The newest and most striking incarnation of this idea can be found in an online game called Empire Avenue, which simulates a stock market in which shares in individuals can be traded and one can track individuals’ market value based on their following in various social media sites, such as Facebook, Twitter, YouTube, and others, as well as demand for their shares by other players.

 

Commodifying social contributions--turning these into currencies that can be accumulated, hoarded, traded, and invested--may have unintended consequences. It could undermine precisely the kind of exchanges and volunteer contributions that are integral to the gift economies they are supposed to promote. In fact the word currency may be the wrong way to describe the incentives for facilitating flows inherent to social creation. The MetaCurrency Project coined the term current-see to emphasize the social flows of the exchanges it is trying to enable. Indeed, we need to invent new language and new terminology to describe the kinds of exchanges and values that comprise core elements of social production. This puts tremendous responsibility on people who design social platforms, because it is these design elements that will determine whether the platforms will foster gift exchange, competition, generosity, or new forms of greed.

We created social technologies. Our next task is to create social organizations: systems for creating not merely goods but also meaning, purpose, and greater good. Can we imagine a society of “private wealth holders whose main objective is to lead good lives, not to turn their wealth into capital?” asks political economist Robert Skidelsky. Or better yet, might they turn their wealth into a different kind of capital—social, emotional, or spiritual? Our technologies are giving us an unprecedented opportunity to do so.

The regression analysis, data visualization and computationally driven sound effects were definitely different. Still, there was much about the weekend's bicoastal datafest that made a newsroom veteran feel right at home: the room full of bleary-eyed obsessives, the wrinkled piles of notes, clothes and discarded potato chip bags, and yes, the bouquet of stale bagels and flop sweat as deadline approached.

We Know Who You Followed Last Summer: Inferring Social Link Creation Times In Twitter

luiy's insight:

ABSTRACT


Understanding a network’s temporal evolution appears to require multiple observations of the graph over time. These often expensive repeated crawls are only able to answer questions about what happened from observation to observation, and not what happened before or between network snapshots. Contrary to this picture, we propose a method for Twitter’s social network that takes a single static snapshot of network edges and user account creation times to accurately infer when these edges were formed. This method can be exact in theory, and we demonstrate empirically for a large subset of Twitter relationships it is accurate to within hours in practice.


We study users who have a very large number of edges or who are recommended by Twitter. We examine the graph formed by these nearly 1,800 Twitter celebrities and their 862 million edges in detail, showing that a single static snapshot can give novel insights about Twitter’s evolution. We conclude from this analysis that real-world events and changes to Twitter’s interface for recommending users strongly influence network growth.

Vanilla contagion: and another Types Of Contagion - Global Economy | Influence et contagion | Scoop.it
In one of a few early hints that Europe might surprise the world with its Cyprus bailout, on February 10th the Financial Times leaked the content of a secret EU memo.
luiy's insight:

In one of a few early hints that Europe might surprise the world with its Cyprus bailout, on February 10th the Financial Times leaked the contentof a secret EU memo. It reported that bank depositor haircuts were among three options being considered to reduce bailout costs. And the memo also warned ominously that "such drastic action could restart contagion in eurozone financial markets."

 

Clearly, policymakers decided to take their chances. And now we're living through the contagion that the memo's authors predicted. But what exactly does that mean? Sure, we can see volatility in asset prices, but how long will it last? Some pundits say it'll blow over like a late afternoon shower on an otherwise sunny day. I disagree.

 

I'll suggest there's more to it than rising market volatility and that we should take a closer look at the meaning of contagion. I'll argue there are three different types at work today: vanilla contagion, latent contagion and stealth contagion. And when you add up the three effects, Cyprus will have a bigger global impact than many expect.

 

Vanilla contagion

This is the term I'll use for a rapid transmission of volatility from one region to another - what most people simply call contagion. We've seen vanilla contagion in financial markets since the announcement of the first bailout agreement on March 16th. We've also seen it in reports of bank customers in the European periphery rethinking their loyalties. Both effects should continue for awhile, especially as EU officials have warned uninsured depositors that their assets aren't protected in government bailouts. This is by far the most significant development of the past two weeks. And it'll play out slowly, since it takes depositors time to find a new home for their assets once they've decided their banks are too risky.

Social selection and peer influence in an online social network

Disentangling the effects of selection and influence is one of social science's greatest unsolved puzzles: Do people befriend others who are similar to them, or do they become more similar to their friends over time? Recent advances in stochastic actor-based modeling, combined with self-reported data on a popular online social network site, allow us to address this question with a greater degree of precision than has heretofore been possible. Using data on the Facebook activity of a cohort of college students over 4 years, we find that students who share certain tastes in music and in movies, but not in books, are significantly likely to befriend one another. Meanwhile, we find little evidence for the diffusion of tastes among Facebook friends—except for tastes in classical/jazz music. These findings shed light on the mechanisms responsible for observed network homogeneity; provide a statistically rigorous assessment of the coevolution of cultural tastes and social relationships; and suggest important qualifications to our understanding of both homophily and contagion as generic social processes.

How Data Science Is Advancing the “Nudge” to Influence Mobile Behaviors

While standing in the checkout line, most shoppers will not weigh all of the pros and cons of donating two dollars to the charity at hand.

Via Don Dea
luiy's insight:
Influencing behaviors that matter

That’s what fuels the application of Nudge — the ability to positively impact business metrics. Every decision that a customer makes, whether to make a purchase, extend service, deepen engagement or recruit friends and family, is a Nudge opportunity and a chance to impact the bottom line.

If mobile operators are applying Nudge to create positive and sustainable changes in customer behaviors that have a real impact on customer revenue and retention, it’s only a matter of time before businesses in other industries discover for themselves that with the help of Data Science, sometimes a Nudge can be more effective than a push or a shove.

Discovering the who, when and how of nudging mobile customers

Leveraging data-driven technologies such as pattern recognition, behavioral clustering, social graphing and predictive analytics, mobile operators are turning to data science and machine learning to advance the application of the Nudge theory — moving from a broad-brush approach to one of micro-targeting.

So how do you determine “who” to Nudge? By understanding how individuals behave over time, we can use pattern recognition approaches to establish fingerprints of each customer and group according to behaviors they have in common — e.g., usage frequency and type, elasticity recharge cycle, social graph authority, etc.

Collective Contagion

Collective Contagion | Influence et contagion | Scoop.it
Intense scientific debate is going around the definition of the foundational concepts and appropriate methodological approaches to deal with the understanding of social dynamics. These challenges are aiming to understand human behavior in its complexity driven by intentional (and not necessarily rational) decisions and influenced by a multitude of factors. The functioning of communication-based mechanisms requires individuals to interact in order to acquire information to cope with uncertainty and thus deeply rely on the accuracy and on the completeness of information (if any). In fact, people’s perceptions, knowledge, beliefs and opinions about the world and its evolution, get (in)formed and modulated through the information they can access. Moreover their response is not linear as individuals can react by accepting, refusing, or elaborating (and changing) the received information. Technology-mediated social collectives are taking an important role in the design of social structures. Yet our understanding of the complex mechanisms governing networks and collective behaviour is still quite shallow. Fundamental concepts like authority, leader-follower dynamics, conflict or collaboration in online networks are still not well defined and investigated – but they are crucial to illuminate the advantages and pitfalls of this form of collective decision-making (which can cancel out individual mistakes, but also make them spiral out of control).

Cyber-harcèlement et e-réputation

Cyber-harcèlement et e-réputation | Influence et contagion | Scoop.it

La publication de contenu sur internet est devenue tellement facile qu'il n'existe plus de profil "type" du cyber-harceleur. Tout le monde peut être victime de cyber-harcèlement.

Toutefois, retrouver, sur internet, des photos ou des vidéos de soi, publiées par un "ex" ou par un tiers mal intentionné, n'est pas une fatalité insurmontable.

De même, diffamations et injures postées sur un blog peuvent être effacées, si l'on sait s'y prendre.

Nous vous proposons ici un vade-mecum des situations de cyber-harcèlement et des solutions existant pour nettoyer sa e-réputation et faire disparaitre des photos ou des vidéos intimes, des textes diffamants, injurieux et/ou dénigrants.

Il est même possible de retrouver et de poursuivre la personne ayant publié les contenus litigieux sur internet (même si certains croient parfois à tort qu'un pseudo leur confère anonymat et impunité).

Le jeu de piste des informations cachées sur internet ne fait que commencer...

La "e-réputation" se définit comme toute information disponible sur internet concernant une personne physique ou une entreprise. 

Le "cyber-harcèlement" consiste à publier de manière répétée dans le temps et/ou sur un grand nombre de sites internet, des informations destinées à salir la e-réputation une personne physique ou morale. 

A l'origine du mal, on notera toujours les mêmes (res)sentiments humains menant au délit : jalousie, rancune, racisme, sexisme, homophobie ou plus simplement un mécontentement. 

Le plus souvent, les auteurs de cyber-harcèlement sont un ancien salarié, un ex-conjoint, un concurrent, un client mécontent, ou plus simplement un autre internaute croisé sur un réseau social, un site de rencontre ou un blog... 

On retrouve même des victimes de cyber-harcèlement dans les écoles et les conséquences peuvent aller, dans des cas extrêmes, jusqu'à la tentative de suicide. 

Le mode d'expression choisi est souvent le même et il se traduit par la publication sur internet d'un texte diffamant, injurieux ou dénigrant ; d'images relevant de la vie privée, parfois très intimes et dénudées...

Structural diversity in social contagion

luiy's insight:

Discussion


Detailed traces of Facebook adoption provide natural sources of data for studying social contagion processes. Our analysis provides a high resolution view of a massive social contagion process as it unfolded over time and suggests a rethinking of the underlying mechanics by which such processes operate. Rather than treating a person’s number of neighbors as the crucial parameter, consider instead the number of distinct social contexts that these neighbors represent as the driving mechanism of social contagion.

 

The role of neighborhood diversity in contagion processes suggests interesting further directions to pursue, both for mathematical modeling and for potential broader applications. Mathematical models in areas including interacting particle systems (28, 29) and threshold contagion (3, 30) have explored some of the global phenomena that arise from contagion processes in networks for which the behavior at a given node has a nontrivial dependence on the full set of behaviors at neighboring nodes. Neighborhood diversity could be naturally incorporated into such models by basing the underlying contagion probability, for example, on the number of connected components formed by a node’s affected neighbors. It then becomes a basic question to understand how the global properties of these processes change when such factors are incorporated.


More broadly, across a range of further domains, these findings suggest an alternate perspective for recruitment to political causes, the promotion of health practices, and marketing; to convince individuals to change their behavior, it may be less important that they receive many endorsements than that they receive the message from multiple directions. In this way, our findings propose a potential revision of core theories for the roles that networks play across social and economic domains.

Here's a bit of science that's contrary to what a heavy utilizer of social networks might expect.

Via BrainHealth

The Harvard study does indicate another thing, which is that social networks are, for now, “light” social interaction. Breaking into a new genre of music, discovering a new favorite director, getting book recommendations, these things don’t occur nearly as much on social networks as their proponents and heavy users would like to think. That’s changing, but Facebook doesn’t appear to be in a hurry to make the change to “serious” social interaction: the kind of trusted exchanges you have with friends in conversation or in repeated encounters over years that slowly convert you into a fan of David Lynch, or Scarlatti, or David Foster Wallace. Those are still the province of real life, it seems, even among the Facebook generation. But for how long?

Social influences kill the wisdom of the crowd

A crowd can sometimes provide wisdom that its individual members lack. But, if you let those individuals talk among themselves, their individual errors can spread throughout the crowd, dragging its wisdom down.

Via Viktor Markowski
luiy's insight:

How important are these effects? Although popular culture has adopted the phrase "wisdom of the crowd" to apply to anything that involves more than a handful of people, the original description of a crowd's wisdom made it clear that it only applied to a limited number of question types and circumstances. So, finding additional limits really shouldn't be much of a surprise. It does, however, serve as an added caution that, just because there's a crowd involved, we shouldn't assume that anything that comes out of the crowd is wise. As the authors note, we seem to have a tendency to make exactly that assumption. "Opinion polls and the mass media largely promote information feedback and therefore trigger convergence of how we judge the facts," they conclude. "The wisdom of crowd effect is valuable for society, but using it multiple times creates collective overconfidence in possibly false beliefs."
