Competition among #memes in a world with limited attention | #SNA #ABM #prediction

Competition among #memes in a world with limited attention | #SNA #ABM #prediction | Think About It! | Scoop.it
The wide adoption of social media has increased the competition among ideas for our finite attention. We employ a parsimonious agent-based model to study whether such a competition may affect the popularity of different memes, the diversity of information we are exposed to, and the fading of our collective interests for specific topics. Agents share messages on a social network but can only pay attention to a portion of the information they receive. In the emerging dynamics of information diffusion, a few memes go viral while most do not. The predictions of our model are consistent with empirical data from Twitter, a popular microblogging platform. Surprisingly, we can explain the massive heterogeneity in the popularity and persistence of memes as deriving from a combination of the competition for our limited attention and the structure of the social network, without the need to assume different intrinsic values among ideas.

luiy's curator insight, February 22, 2014 8:06 AM

Here we outline a number of empirical findings that motivate both our question and the main assumptions behind our model. We then describe the proposed agent-based toy model of meme diffusion and compare its predictions with the empirical data. Finally we show that the social network structure and our finite attention are both key ingredients of the diffusion model, as their removal leads to results inconsistent with the empirical data.

 

-----------------------------

Limited attention


We first explore the competition among memes. In particular, we test the hypothesis that the attention of a user is somewhat independent from the overall diversity of information discussed in a given period. Let us quantify the breadth of attention of a user through Shannon entropy S = −Σi f(i) log f(i) where f(i) is the proportion of tweets generated by the user about meme i. Given a user who has posted n messages, her entropy can be as small as 0, if all of her posts are about the same meme; or as large as log n if she has posted a message about each of n different memes. We can measure the diversity of the information available in the system analogously, defining f(i) as the proportion of tweets about meme i across all users. Note that these entropy-based measures are subject to the limits of our operational definition of a meme; finer or coarser definitions would yield different values.

The Future of Digital Retail

The Future of Digital Retail | Think About It! | Scoop.it

The next two years will bring about new behavioural realities of device connected retail environments. What sort of shopper habits will develop as new retail technologies become widespread and expected by the consumer? And most importantly, what can retailers actually do about it?


Yes, current retail environments (both on and offline) are data-rich and increasingly personalised. But culture hasn’t caught up yet. In the past, technological advances in retail have been defined by the friction they introduced to the shopping process, rather than convenience. Think of the current state of self-checkouts; theoretically timesaving, but in practice just an often-broken inconvenience. It hardly feels like progress.


But not for long. Retailers are growing savvy and sophisticated in their use of new technologies to improve customer experience (and their bottom line). As these realities take hold and culture adapts around new technological promise, entirely new consumer patterns and expectations will emerge....

Becoming customer centric isn't easy -and is much harder for companies who have a long history of working with their clients Face to Face. Retailers have a big challenge, they need to balence the high cost of real estate, manage a great on line website and train their staff on new ways to interact. Customer expecations continue to rise and keeping up with an engaging experience requires constant innovation. 

SageRave's curator insight, March 7, 12:52 PM

Internet freelancers should not ignore these predictions, but they be careful about using predictions as their sole basis for client acquisition and retention. They are clues, revealing where freelancers might focus their efforts.

Elaine J Roberts, Ph.D.'s curator insight, March 9, 3:20 PM

Many of us already do a lot of shopping online; some of us shop online almost exclusively. A really powerful insight: "Handled clumsily, retailers who predict consumer preferences will be perceived as subverting customer choice. But retailers who use their predictive algorithms to create simplified choice for their customers, while maintaining a consumer’s ability to evaluate and make unilateral purchasing decisions, will thrive."

What comes after Google Glass? It was at CES, just in pieces | Think About It! | Scoop.it
Will smart glasses, such as Google Glass, go mainstream any time soon? CES 2015 offered a few promising candidates.
John Caswell's insight:

Smartwatches were the wearable darling of CES 2015, but they're easy to create. Start with fitness tracking, throw in some notifications, maybe even park your car with them, and you've got the latest buzzworthy product.

Smart glasses are much harder. Bringing information directly to a person's eye has the potential to reduce the friction between humans and technology more than any other wearable, but they need to walk a difficult tightrope between convenience and intrusion. And to have any hope with consumers, smart glasses can't look like something only the characters from The Big Bang Theory would wear.

The Future of Libraries Has Little to Do with Books

The Future of Libraries Has Little to Do with Books | Think About It! | Scoop.it
Will 2015 be the year that the public library makes a comeback?
John Caswell's insight:

On a Monday morning between Christmas and New Year’s Eve in Paris, the line for modern art museum Centre Georges Pompidou winds around the block. But the patrons waiting in the cold aren’t there to catch a glimpse of a Magritte—they’re young locals queueing for access through the museum’s back door to another attraction: Bibliothèque publique d'information, or the public library.

In a digital age that has left book publishers reeling, libraries in the world’s major cities seem poised for a comeback, though it’s one that has very little to do with books. The Independent Library Report—published in December by the U.K.’s Department for Culture, Media, and Sport—found that libraries across the nation are re-inventing themselves by increasingly becoming “vibrant and attractive community hubs,” focusing on the “need to create digital literacy—and in an ideal world, digital fluency.”

John Caswell's insight:

Free WiFi isn’t an entirely new project. Coke may have lifted its idea from a much more limited project by Japanese soft drink giant Asahi, who in 2011 plopped down hundreds of WiFi-equipped vending machines in tourist hubs with a fifty-meter signal and thirty-minute access limit. Nor is it entirely altruistic when corporations lead it. Coke probably hopes that clustering people around its machines will give it a nice PR and sales boost.
