Google‘s AI team has released a new tool to help researchers traverse through a trove of coronavirus papers, journals, and articles. The COVID-19 research explorer tool is a semantic search interface that sits on top of the COVID-19 Open Research Dataset (CORD-19). 

The team says that traditional search engines are sufficient at answering queries such as “What are the symptoms of coronavirus?” or “Where can I get tested in my country?”. However, when it comes to more pointed questions from researchers, these search engines and their keyword-based approach fail to deliver accurate results.

Google‘s new tool helps researchers solve that problem. The CORD-19 database has over 50,000 journal articles and research papers related to coronavirus. However, a simple keyword search wouldn’t yield reliable results. So, Google uses Natural Language Understanding (NLU) based semantic search to answer those queries. 

NLU is a subset of Natural Language Processing (NLP) that focuses on a smaller context while trying to derive the meaning of the question and draw distinct insights.

The COVID-19 research explorer tool not only returns related papers to the query, but it also highlights parts of papers that might provide relevant answers to the question. You can also ask follow-up questions to further narrow down results.

The semantic search is powered by Google’s popular BERT language model. In addition to that, the AI has been trained on BioASQ, a biomedical semantical search model to enhance results.

The team built a hybrid term-neural retrieval model for better results. While the term-based model provides accuracy with search results, the neural model helps with understanding the meaning and context of the query.

You can read more technical details about the model here and try out the search explorer here.

If you’re looking for data, your search should start here. Google’s Dataset Search just launched as a full-fledged search tool, and it’s about as good as you’d expect. Google does a masterful job of collating all kinds of datasets from all across the internet with useful info like publication data, authors and file types available before you even click through. From NFL stats from the ’70s to catch records of great white sharks in the northwest Pacific, it seems to have it all. There are about 25 million datasets available now — actually just “a fraction of datasets on the web,” Google told the Verge — but more will be available as data hosts update their metadata.

Is there a word for that? Last week, as I took what must have been my hundredth Uber or Lyft ride at the tail end of two weeks of travel, I publicly wondered if there was a word for the specific type of small talk you make with a rideshare driver. (There isn’t, but I tip my hat to my former editor, Anne Glover, for whipping “chauffeurenfreude” together.) Different languages often feature unique words that capture seemingly indescribable feelings or experiences that don’t translate well at all. Here’s a website that keeps track of them.

This messaging app will self-destruct in 10 seconds. Literally. Well, not literally. There’s no explosion. But with Yap, messages (between up to six people) exist only until you type your next message, taking “ephemeral” to a whole new level. It seems to me that this is more of a proof of concept that shows the internet doesn’t have to be forever (imagine that!) and less of an actual useful tool for journalists. But the folks who subscribe to this newsletter are smart cookies. Prove me wrong.

Facebook just gave you access to some more of what it knows about you. Because of multi-site logins and Facebook ads, Facebook receives all kinds of information about users’ activities on other apps and websites. With the new Off-Facebook Activity tool, you can see and control exactly where that happens. “You might be shocked or at least a little embarrassed by what you find in there,” writes Washington Post tech columnist Geoffrey A. Fowler, and he couldn’t be more right — by piecing info together from my history, you can tell that I have a chronic bad habit of ordering late-night Domino’s pizza.

If you needed another reminder to use caution online, here it is. The Tampa Bay Times, which Poynter owns, was the latest news organization to be hit by a nasty ransomware attack. The Times reported that it is unclear how the attack was carried out, so I can’t give you specific tips for avoiding a similar fate, but it’s a good reminder that any organization is only as safe as its weakest link. There are tools that can help — a good password manager and a well-placed firewall, for starters — but exercising good internet safety hygiene is the best first step. Be skeptical of emails from unknown senders, especially those with attachments. Keep your operating systems and software updated. And don’t use weak passwords (and especially don’t use the same weak passwords across multiple websites).

Weird news is often harmful to the most vulnerable members of society. I cringe every time I see a “Florida Man” story (my colleague Al Tompkins lays out why that is here), but many stories labeled “weird” or “dumb/stupid criminals” capitalize on human misery. Some of these stories may seem funny, but at whose expense?

Here’s a tool that displays every road in a city. It’s an interesting way to look at any metropolitan area, town or hamlet — from the world’s biggest city of Chongqing, China (population: 30 million), all the way down to my humble hometown of Gasport, New York (population: 1,248). Plus, you can export each one as a .png or editable .svg file. (Just a warning: Smaller locales seem to take a long time to load, if they even do at all.)


Bookmark this publishing tool in case it’s the next best thing (it probably is). The founding CEO of Chartbeat, a ubiquitous realtime analytics tool for newsrooms, is back at it with new project. It’s called Scroll and it massively improves the reading experience by removing ads and loading pages faster. My colleague, Rick Edmonds, has more about its founder and the future of the platform.

WikiHow’s bizarre art has been plastered all over the internet since 2005. Many of its pieces feature odd scenes that would probably never happen in real life. You’ve probably seen them repurposed in meme form. Here’s the strange story about how they’re made (and yes, it features some human misery, though we’re not making fun of it here).

Australians can now trust that Dr Google is providing them with reliable information.

Google search results will now show accurate information, fact checked by a panel of doctors and the Mayo Clinic, for over 900 commonly searched for health conditions.

The new "health cards" feature, launched by the internet giant on Wednesday, will include an outline of the condition, symptoms, diagnosis, and prevalence according to age at the top of search results.

For some conditions you'll also see high-quality illustrations from licensed medical illustrators.


With one in 20 online searches related to health, Google says they want to empower their users.

The Australian Medical Association (AMA) has welcomed the new Google health tool but has issued caution.

Tony Bartone from the AMA says anything that improves or supports a patient's health literacy is a good thing.

"What this has done has improved the quality and accuracy of the information people will get when they do the very frequent health searches because up until now the results of the searches were indiscriminate in terms of their veracity and reliability."

But the information should not be used to form a diagnosis, warned Dr Bartone.

"It is information - it is not knowledge. It is essentially to aid a person's understanding around a certain condition," he said.

"A diagnosis is based upon taking a history, an examination and knowing the past medical history of that patient and a management plan is formulated on all those inputs," said Dr Bartone.

Any health concerns should be discussed with a GP.

A new Canadian-made Internet search tool that detects child sexual abuse images online has logged more than five million unique web pages with 40,000 images in the past six weeks alone, the Toronto Star has learned.

Project Arachnid, created by the Winnipeg-based Canadian Centre for Child Protection, is searching 150 web links a second for child abuse imagery in an effort to have it removed from public view, a form of lingering abuse for victims.

When the search tool identifies illegal material, the centre sends notices to the site host requesting its removal.


“If we can make this content more difficult to find, the breadth of exposure for victims will diminish over time,” says Signy Arnason, director of Cypertip.ca, a project of the Centre which receives tips about child abuse from across the world.

One of the most powerful findings from an international survey of 128 child abuse victims being released today by the centre is the lifelong impact that exploitative images published online can have on victims, including ongoing paranoia and fear of being stalked, sleeplessness, poor self-image, “powerlessness” and “shame and humiliation.”

“The fact that images/videos of a child’s sexual abuse were created at all, not to mention that they may still be possessed by the abuser and be publicly available for others to access, has an enormous negative impact on the individual,” the study says. “The impact can perpetuate into adulthood and may reduce the ability of an individual to recover and function in society.”

Among respondents, 73 per cent said they worry about being recognized; 88 per cent believe it has affected their education/academics; 91 per cent believe it has affected their employment; and 93 per cent believe it has affected friendships.
