Abstract

Massive amounts of fake news and conspiratorial content have spread over social media before and after the 2016 US Presidential Elections despite intense fact-checking efforts. How do the spread of misinformation and fact-checking compete? What are the structural and dynamic characteristics of the core of the misinformation diffusion network, and who are its main purveyors? How to reduce the overall amount of misinformation?

To explore these questions we built Hoaxy, an open platform that enables large-scale, systematic studies of how misinformation and fact-checking spread and compete on Twitter. Hoaxy filters public tweets that include links to unverified claims or fact-checking articles. We perform k-core decomposition on a diffusion network obtained from two million retweets produced by several hundred thousand accounts over the six months before the election. As we move from the periphery to the core of the network, fact-checking nearly disappears, while social bots proliferate. The number of users in the main core reaches equilibrium around the time of the election, with limited churn and increasingly dense connections.

We conclude by quantifying how effectively the network can be disrupted by penalizing the most central nodes. These findings provide a first look at the anatomy of a massive online misinformation diffusion network.

“Lovereading.co.uk has published a new infographic that begs the question of what would happen if some of our favorite villains from children’s books were put on trial in a UK court.

The graphic lists sixteen characters, including their crimes, literary source, and estimated punishment.

Do you see any characters missing that should go on this graphic? (Mattilda’s dad is absent, for example, and so is the Wizard of Oz.)”

Storytelling app Wattpad raises $51M at a $398M valuation

“Content, as they say, is king — but these days, that may be true only for as long as you can figure out a good business model to deliver it. And today, a startup based out of Toronto, Canada is re-upping its coffers to fill out its ambition to do just that.

Wattpad, a storytelling and reading/viewing app that combines crowdsourced content with professionally produced material, has picked up another $51 million (C$61.25 million) in venture funding — money that it plans to use to invest in its tech (such as the machine learning that helps match its creators with consumers, and which identifies stories that are ‘trending’ and worth revisiting for more creative writing and video shooting around them as themes); and in its expansion into more formats.”

Wired: AI BEAT HUMANS AT READING! MAYBE NOT

AI BEAT HUMANS AT READING! MAYBE NOT

https://www.wired.com/story/ai-beat-humans-at-reading-maybe-not/

“NEWS SPREAD MONDAY of a remarkable breakthrough in artificial intelligence. Microsoft and Chinese retailer Alibaba independently announced that they had made software that matched or outperformed humans on a reading-comprehension test devised at Stanford. Microsoft called it a “major milestone.” Media coverage amplified the claims, with Newsweek estimating “millions of jobs at risk.”

Those jobs seem safe for a while. Closer examination of the tech giants’ claims suggests their software hasn’t yet drawn level with humans, even within the narrow confines of the test used.”
