Platforms struggle to keep up with moderating content amid COVID-19 – Clearwater Times

Published

 on


While hundreds of thousands of companies across the country have seen work grind to a halt amid COVID-19, Chris Priebe is experiencing the opposite.

The owner of Two Hat, an artificial intelligence-powered content moderation company based in Kelowna, B.C., has never been busier helping customers including gaming brands Nintendo Switch, Habbo, Rovio and Supercell sift through billions of comments and conversations and quickly identify and remove anything harmful to users.

“We processed 60 billion last month. It used to be 30 billion. That’s how bad coronavirus is. That is at least twice the normal volume,” said Priebe in April, before monthly processing volumes hit 90 billion.

“(Platforms) are faced with, in some cases, 15 times the volume. How can they possibly care for their audience? Because that doesn’t mean that the revenues are up 15 times or that they can afford to hire that many more people.”

Priebe is not alone in the scramble to keep online, social media and gaming platforms safe amid COVID-19. Companies including Facebook, Instagram, Twitter, YouTube and Google have all been warning users since at least April that they are experiencing shortages of content moderators, causing a backlog in the removal of harmful posts.

The stakes are high. Record numbers of people around the globe are spending increased amounts of time at home on their favourite platforms, challenging servers and turning messaging services, social networks and comment sections into a wild west.

The situation has heightened privacy experts’ worries about the spread of misinformation and the likelihood that users will stumble upon hate speech, pornography, violence and other harmful content.

“Quite a few people are fairly dissatisfied with the content moderation process as it is…and then you add on this pandemic…You are seeing a huge increase in harassing behaviour and problematic behaviour and then having the content stay up longer,” said Suzie Dunn, a University of Ottawa professor who specializes in the intersection of technology, equality and the law.

“It’s a real challenge because content moderators are a little bit like frontline workers. They’re an essential service that we need to have at a time like this, so we would hope to see more content moderators working.”

However, unlike workers in other sectors who have been working from home since the COVID-19 pandemic arrived, such a shift is difficult for many content moderators as their jobs deal with images and language you wouldn’t want kids or other family members catching a glimpse of.

“Some of them may not be able to work on certain things that they would work on in the office,” Kevin Chan, Facebook Canada’s head of public policy, told The Canadian Press.

“They’re looking at potentially private, and sensitive things that have been reported to them and we need to make sure….that these things can be treated in the secure and private manner that they deserve.”

Full-time Facebook employees have stepped up and are taking on some of the moderating work, including from contractors who can’t have proprietary and sensitive content at home. These workers are dealing with content related to “real-world harm” like child safety and suicide and self-injury.

“There is no question this is going to pose challenges to the degree to which we can be as responsive,’ Chan said.

To deal with the situation, Facebook has rolled out measures meant to curb the flow of COVID-19 misinformation and is focused on weeding out and removing content around terrorism and anything inciting violence or linking to “dangerous” individuals and organizations.

At Twitter, machine learning and automation is being used to help the company review reports most likely to cause harm first and to help rank content or “challenge” accounts automatically.

“While we work to ensure our systems are consistent, they can sometimes lack the context that our teams bring, and this may result in us making mistakes,” Twitter said in a blog. ”As a result, we will not permanently suspend any accounts based solely on our automated enforcement systems.”

Google has also upped its reliance on machine-based systems to reduce the need for people to work from the office and said the increase in automation has many downsides, including a potential increase in content classified for removal and slower turnaround times for appeals.

“They are not always as accurate or granular in their analysis of content as human reviewers,” added a Google blog released in March.

This is a sentiment Priebe has encountered many times, but he has a counter-argument: “AI is not perfect but…humans are also not perfect.”

He gives the example of a child playing a game at home during the pandemic, when pedophiles might be more active online and trying to contact young people.

“You have three different humans look at the same conversation and they’re not going to give you the same answer. Some of them are going to call it grooming and some of them aren’t,” said Priebe.

Priebe believes an ideal system blends humans and AI because the latter is good at knowing what to do with obvious cases like when a user’s content is flagged almost a dozen times in a short period of time or when someone gets a message that only reads hello and hits report just to see what the button does.

“You don’t need a human to have to be looking at their screen and looking at this absolutely sexual content in front of potentially their children who snuck up behind them because artificial intelligence is going to win every time on that,” he said.

“Let humans do what humans do well, which is deal with that middle category of stuff that is subjective, difficult or hard to understand, that the AI is not confident about.”

Regardless of how the moderation gets done, some things will always slip through the cracks, especially in a pandemic, said Dunn.

“No system is perfect.”

Here’s how Helene and other storms dumped a whopping 40 trillion gallons of rain on the South

Published

 on

 

More than 40 trillion gallons of rain drenched the Southeast United States in the last week from Hurricane Helene and a run-of-the-mill rainstorm that sloshed in ahead of it — an unheard of amount of water that has stunned experts.

That’s enough to fill the Dallas Cowboys’ stadium 51,000 times, or Lake Tahoe just once. If it was concentrated just on the state of North Carolina that much water would be 3.5 feet deep (more than 1 meter). It’s enough to fill more than 60 million Olympic-size swimming pools.

“That’s an astronomical amount of precipitation,” said Ed Clark, head of the National Oceanic and Atmospheric Administration’s National Water Center in Tuscaloosa, Alabama. “I have not seen something in my 25 years of working at the weather service that is this geographically large of an extent and the sheer volume of water that fell from the sky.”

The flood damage from the rain is apocalyptic, meteorologists said. More than 100 people are dead, according to officials.

Private meteorologist Ryan Maue, a former NOAA chief scientist, calculated the amount of rain, using precipitation measurements made in 2.5-mile-by-2.5 mile grids as measured by satellites and ground observations. He came up with 40 trillion gallons through Sunday for the eastern United States, with 20 trillion gallons of that hitting just Georgia, Tennessee, the Carolinas and Florida from Hurricane Helene.

Clark did the calculations independently and said the 40 trillion gallon figure (151 trillion liters) is about right and, if anything, conservative. Maue said maybe 1 to 2 trillion more gallons of rain had fallen, much if it in Virginia, since his calculations.

Clark, who spends much of his work on issues of shrinking western water supplies, said to put the amount of rain in perspective, it’s more than twice the combined amount of water stored by two key Colorado River basin reservoirs: Lake Powell and Lake Mead.

Several meteorologists said this was a combination of two, maybe three storm systems. Before Helene struck, rain had fallen heavily for days because a low pressure system had “cut off” from the jet stream — which moves weather systems along west to east — and stalled over the Southeast. That funneled plenty of warm water from the Gulf of Mexico. And a storm that fell just short of named status parked along North Carolina’s Atlantic coast, dumping as much as 20 inches of rain, said North Carolina state climatologist Kathie Dello.

Then add Helene, one of the largest storms in the last couple decades and one that held plenty of rain because it was young and moved fast before it hit the Appalachians, said University of Albany hurricane expert Kristen Corbosiero.

“It was not just a perfect storm, but it was a combination of multiple storms that that led to the enormous amount of rain,” Maue said. “That collected at high elevation, we’re talking 3,000 to 6000 feet. And when you drop trillions of gallons on a mountain, that has to go down.”

The fact that these storms hit the mountains made everything worse, and not just because of runoff. The interaction between the mountains and the storm systems wrings more moisture out of the air, Clark, Maue and Corbosiero said.

North Carolina weather officials said their top measurement total was 31.33 inches in the tiny town of Busick. Mount Mitchell also got more than 2 feet of rainfall.

Before 2017’s Hurricane Harvey, “I said to our colleagues, you know, I never thought in my career that we would measure rainfall in feet,” Clark said. “And after Harvey, Florence, the more isolated events in eastern Kentucky, portions of South Dakota. We’re seeing events year in and year out where we are measuring rainfall in feet.”

Storms are getting wetter as the climate change s, said Corbosiero and Dello. A basic law of physics says the air holds nearly 4% more moisture for every degree Fahrenheit warmer (7% for every degree Celsius) and the world has warmed more than 2 degrees (1.2 degrees Celsius) since pre-industrial times.

Corbosiero said meteorologists are vigorously debating how much of Helene is due to worsening climate change and how much is random.

For Dello, the “fingerprints of climate change” were clear.

“We’ve seen tropical storm impacts in western North Carolina. But these storms are wetter and these storms are warmer. And there would have been a time when a tropical storm would have been heading toward North Carolina and would have caused some rain and some damage, but not apocalyptic destruction. ”

‘Big Sam’: Paleontologists unearth giant skull of Pachyrhinosaurus in Alberta

Published

 on

 

It’s a dinosaur that roamed Alberta’s badlands more than 70 million years ago, sporting a big, bumpy, bony head the size of a baby elephant.

On Wednesday, paleontologists near Grande Prairie pulled its 272-kilogram skull from the ground.

They call it “Big Sam.”

The adult Pachyrhinosaurus is the second plant-eating dinosaur to be unearthed from a dense bonebed belonging to a herd that died together on the edge of a valley that now sits 450 kilometres northwest of Edmonton.

It didn’t die alone.

“We have hundreds of juvenile bones in the bonebed, so we know that there are many babies and some adults among all of the big adults,” Emily Bamforth, a paleontologist with the nearby Philip J. Currie Dinosaur Museum, said in an interview on the way to the dig site.

She described the horned Pachyrhinosaurus as “the smaller, older cousin of the triceratops.”

“This species of dinosaur is endemic to the Grand Prairie area, so it’s found here and nowhere else in the world. They are … kind of about the size of an Indian elephant and a rhino,” she added.

The head alone, she said, is about the size of a baby elephant.

The discovery was a long time coming.

The bonebed was first discovered by a high school teacher out for a walk about 50 years ago. It took the teacher a decade to get anyone from southern Alberta to come to take a look.

“At the time, sort of in the ’70s and ’80s, paleontology in northern Alberta was virtually unknown,” said Bamforth.

When paleontogists eventually got to the site, Bamforth said, they learned “it’s actually one of the densest dinosaur bonebeds in North America.”

“It contains about 100 to 300 bones per square metre,” she said.

Paleontologists have been at the site sporadically ever since, combing through bones belonging to turtles, dinosaurs and lizards. Sixteen years ago, they discovered a large skull of an approximately 30-year-old Pachyrhinosaurus, which is now at the museum.

About a year ago, they found the second adult: Big Sam.

Bamforth said both dinosaurs are believed to have been the elders in the herd.

“Their distinguishing feature is that, instead of having a horn on their nose like a triceratops, they had this big, bony bump called a boss. And they have big, bony bumps over their eyes as well,” she said.

“It makes them look a little strange. It’s the one dinosaur that if you find it, it’s the only possible thing it can be.”

The genders of the two adults are unknown.

Bamforth said the extraction was difficult because Big Sam was intertwined in a cluster of about 300 other bones.

The skull was found upside down, “as if the animal was lying on its back,” but was well preserved, she said.

She said the excavation process involved putting plaster on the skull and wooden planks around if for stability. From there, it was lifted out — very carefully — with a crane, and was to be shipped on a trolley to the museum for study.

“I have extracted skulls in the past. This is probably the biggest one I’ve ever done though,” said Bamforth.

“It’s pretty exciting.”

The ancient jar smashed by a 4-year-old is back on display at an Israeli museum after repair

Published

 on

 

TEL AVIV, Israel (AP) — A rare Bronze-Era jar accidentally smashed by a 4-year-old visiting a museum was back on display Wednesday after restoration experts were able to carefully piece the artifact back together.

Last month, a family from northern Israel was visiting the museum when their youngest son tipped over the jar, which smashed into pieces.

Alex Geller, the boy’s father, said his son — the youngest of three — is exceptionally curious, and that the moment he heard the crash, “please let that not be my child” was the first thought that raced through his head.

The jar has been on display at the Hecht Museum in Haifa for 35 years. It was one of the only containers of its size and from that period still complete when it was discovered.

The Bronze Age jar is one of many artifacts exhibited out in the open, part of the Hecht Museum’s vision of letting visitors explore history without glass barriers, said Inbal Rivlin, the director of the museum, which is associated with Haifa University in northern Israel.

It was likely used to hold wine or oil, and dates back to between 2200 and 1500 B.C.

Rivlin and the museum decided to turn the moment, which captured international attention, into a teaching moment, inviting the Geller family back for a special visit and hands-on activity to illustrate the restoration process.

Rivlin added that the incident provided a welcome distraction from the ongoing war in Gaza. “Well, he’s just a kid. So I think that somehow it touches the heart of the people in Israel and around the world,“ said Rivlin.

Roee Shafir, a restoration expert at the museum, said the repairs would be fairly simple, as the pieces were from a single, complete jar. Archaeologists often face the more daunting task of sifting through piles of shards from multiple objects and trying to piece them together.

Experts used 3D technology, hi-resolution videos, and special glue to painstakingly reconstruct the large jar.

Less than two weeks after it broke, the jar went back on display at the museum. The gluing process left small hairline cracks, and a few pieces are missing, but the jar’s impressive size remains.

The only noticeable difference in the exhibit was a new sign reading “please don’t touch.”
