OpenAlex rewrite enters beta! �
Jason: It’s a big week at OpenAlex. On Monday, we announced that OpenAlex is now our top-level brand (and retired the “OurResearch” name). Yesterday we unveiled our new logo. And today, we’re thrilled to launch the beta release of our fully-rewritten codebase (codenamed Walden)!Walden is faster, bigger, and more maintainable–that means quicker bug fixes, more content, easier feature development, and a smoother experience all around.Throughout October, we’ll be running Walden and the old system (Classic) side by side, with Classic remaining the default. On November 1 2025, Walden becomes default, and we’ll publish the last data snapshot from the old system (more info on timelines here).How to test-drive WaldenWalden beta is already live in the API and UI so you can start exploring it right away!In the UI: click the little test-tube icon in the top right (or click here).In the API: just add data-version=2 to your request, like this: https://api.openalex.org/works?data-version=2.In OREO: Compare Classic to Walden using the OpenAlex Rewrite Evaluation Overview (OREO, yum). Using OREO you can see exactly what’s changed (good and bad), view known issues, and track our continuous improvements throughout our October betaJust remember that it’s still in beta: there are lots of known issues and it’s changing every day. If you notice an that’s not already in OREO tests or known issues, report it here.Key improvementsWhen you check it out, what should you expect to see? The best way to view a list of improvements is to check out the tests in OREO, especially work tests. But here’s a high-level overview:150M new works: Newly indexed articles, books, datasets, software, dissertations, and more! You can explore just the newly added works here.Better consistency: Unpaywall and OpenAlex will now always agree.Better metadata: more citations, more language and retraction coverage, better keywords, more OA data.Looking AheadThe last year of rewriting OpenAlex was tough. We couldn’t move as fast as we wanted on new features, and support often lagged. But now we’re equipped to move fast without breaking things. Expect faster improvements, better support, and more ambitious features dropping in Q4, including:Community curation: fix mistakes (like in Wikipedia) and see them reflected in days.Vector search endpoint: find relevant works and other entities based on semantic similarity of free-form textDownload endpoint: Access PDF text from DOI or OpenAlex IDBetter funding metadata: New grants entity with better coverage of grant objects and linkages to research outputs and fundersThis is a turning point for OpenAlex—and we’re excited to build the future of research infrastructure together with you. The engine’s rebuilt. The road ahead is wide open. Let’s go.PS want to learn more about Walden? Come to our webinar Oct 7th at 10am Eastern. You can register to attend here.The post OpenAlex rewrite enters beta! � appeared first on OpenAlex blog.

We’re now OpenAlex
Jason: For years, we’ve been working under the name OurResearch. That name sat at the top of our org chart, with three child projects under it: OpenAlex, Unpaywall, and Unsub.Starting today, things are simpler: that org chart now has just one parent—OpenAlex—with Unpaywall and Unsub beneath it.Why the change? Three reasons:1. Fewer brands is clearerWe’re a tiny team, and having so many brands has always been confusing. People wondered: are we OurResearch (or Our Research), or OpenAlex, or Unpaywall, or something else? From now on, the answer is simple: we’re OpenAlex.2. OpenAlex is what we doMore and more, OpenAlex is the center of our work. It’s our biggest project and the one that takes most of our time. And it’s also the data engine behind our other projects: Unpaywall and Unsub both run on OpenAlex data. In fact, with the launch of our fully rewritten OpenAlex codebase (codenamed Walden) this week, Unpaywall runs as a subroutine of the OpenAlex codebase.So in a real sense, Unpaywall and Unsub are just friendly wrappers around OpenAlex. Improving OpenAlex improves them automatically.And the name OpenAlex, with its homage to the ancient Library of Alexandria, captures our long-term vision to gather, organize, and make open all scholarly information.3. New name, new startLegally, nothing dramatic is happening—our official name has always been Impactstory, Inc., and “OurResearch” was just a DBA. But this moment is more than just a bookkeeping change.This is a new chapter for us. The past year has been tough: not much visible progress, a lot of repaying technical debt, and a long slog to rewrite our entire codebase. But that rewrite launches (in beta) this week. And with a fresh codebase comes a fresh start: we get to focus harder, move faster, and pour our energy into making OpenAlex as comprehensive, accurate, and open as possible.So yes, the name change simplifies things. But more importantly, it marks a new focus and a renewed commitment to our vision: building a universal library of scholarship.And while we’ll continue to support Unpaywall and Unsub for now, we want to be transparent: OpenAlex is the future. As its functionality grows over the next year or two, Unpaywall and Unsub users will be able to meet their use-cases directly via OpenAlex. The rising tide of OpenAlex lifts all boats.This week is about OpenAlexThis post is the first of three announcements:Monday: our name change to OpenAlex (that’s today).Tuesday: our new logo.Wednesday: the beta launch our fully rewritten OpenAlex codebase.When we say we’re focusing on OpenAlex, it’s not just words—we’re shipping, this week. And there’s more coming in Q4:A new API endpoint to directly download PDFs and parsed PDFs.A self-serve curation portal (think Wikipedia editing, but for scholarly metadata), where your changes go live in a day or two.A new vector search API.Improved funder coverage, thanks to our new Wellcome Trust grant.After a year of rebuilding, we’ve finally got the tools and the focus we need start delivering more substantively on our vision: a universal, open library of scholarly information. We’re energized. We’re ready. We’re OpenAlex.The post We’re now OpenAlex appeared first on OpenAlex blog.

National park to remove exhibit of famed photograph showing former slave’s scarred back, says report
Io Dodds: In 1863, at the height of the Civil War, two Baton Rouge photographers captured an image of a former slave's horrifically scarred back that shocked white Americans across the Union.Now that photo is among dozens of exhibits about slavery at several national parks, which have reportedly been ordered removed by the Trump administration.According to The Washington Post, National Park Service officials have taken exception to various signs and displays at the Harpers Ferry National Historic Park in West Virginia and George Washington's old house in Philadelphia, where the first U.S. president kept nine slaves. All were deemed to violate Trump's executive order on

Vivaldi will keine KI-Agenten im Browser
Eva-Maria Weiß: (Bild: photoschmidt/ Shutterstock.com)Wer KI-Agenten im Browser nutzt, lasse Big Tech entscheiden, was man sieht, sagt Vivaldi. Man sei nur noch ein passiver Zuschauer. Alle gängigen Browseranbieter stellen KI-Agenten zur Verfügung. Manche KI-Unternehmen entwickeln Browser, die auf den KI-Agenten basieren. Nur Vivaldi nicht. Das norwegische Unternehmen, das den gleichnamigen Browser entwickelt, stellt sich gegen diesen Trend.

Unpaywall improvements: more gold, better green
Jason: We recently announced that we’d completely rewritten Unpaywall to make it faster, more accurate, and (most importantly) easier to fix and improve. We wanted to move Unpaywall from product to process, something we could continuously improve along with the community.Well, we’ve been working hard on that over the last few months and here’s an update!Better Gold coverageBy far the most common OA color is gold. In fact, based on our manual sampling, 25% of Crossref DOIs are gold OA, which is much higher than I’d expected and much higher than it used to be. (note: in this and all following stats we exclude component DOIs, which aren’t indexed in Unpaywall).Coverage of gold is very tricky, because it’s all about the status of the work’s source, not the work itself. So we need very comprehensive coverage of sources, which is as hard as it sounds.Of course there’s DOAJ which is fantastic but they only cover a small subset of gold OA journals. And even for those journals, DOAJ often only tells us that a given journal is fully OA since a certain date—we still need to figure out if the back catalog is open or not.In recent weeks, we’ve finished several projects to add the “this is gold OA” flag to new journals:We crawled 50k OJS journals, adding gold status to 17,000 of them (many thanks to Juan Pablo Alperin and Diego Chavarro for their help in getting a list of OJS journals!)We marked 1,200 new journals gold using data from J-STAGE.We marked 100 new journals gold using data from SciELOWe added gold status to several dozen journals from fully-OA publishers including including MDPI, Academic Journals, and Edorium.We also modified our algorithm to assign gold instead of bronze when we know an article is OA, but we can’t figure out its source. Since gold is 2.5x more common than bronze, this will result in fewer errors overall.Overall, this has made a big change in our gold coverage: now 19% of Unpaywall is gold, compared to 14% in May.Green OAWe’ve made several changes in our green OA approach. These have not increased our total green percentage, but they have made our assignment of colors more consistent.The rule for green has always been that if the best OA location is in a repository, it’s green. But, like gold, this is very dependent on us correctly describing the source as a repository. We’re very good at this for institutional repositories—but we’ve not been so good for preprint and data repositories, which are both much more common today then they were when we started Unpaywall.Other changesWe fixed a bug causing us to list works published under the Elsevier User License as Hybrid. Since we don’t consider that to be an OA license, we moved these to bronze.We marked SSRN as an open repository…it’s on the bubble but since all works are available free right away, for us it counts.ResultsThe “ground truth” dataset is a random sample of 500 DOIs from Crossref. It excludes component DOIs and DOIs that don’t resolve. Each DOI is manually annotated by our team, which often includes doing lots of research on the journals and repositories that host the content. The definitions of oa_status colors come from here, which is in turn based on the original 2018 Unpaywall paper in PeerJ.As you can see, we’re moving in the correct direction when it comes to gold and hybrid, green isn’t changing, and bronze coverage is going backwards a bit, although it’s still pretty close to the ground truth number. Our roadmap will prioritize green and gold for the next few months at least.The futureThe most important change for Unpaywall moving forward is the upcoming rewrite of OpenAlex, which will be gradually rolled out October-November of this year. That’s because when this rewrite is deployed, OpenAlex and Unpaywall will finally share the exact same codebase. Of course this will eliminate those pesky, embarrassing bugs where Unpaywall and OpenAlex disagree. But more importantly, it’ll link the large Unpaywall and OpenAlex communities, allowing everyone to improve both products together.Even before that, though, we’ll be unveiling another exciting change: a new and improved curation portal. This will make it easier to fix article-level bugs in Unpaywall, including bugs that current curation solution doesn’t address (like missing PDF URLs and incorrect licenses). Even cooler, though it’ll allow users to fix source-level bugs, particularly fixing journals that should be marked gold, but aren’t. Although someday AI might let us automate this, for now, we think that active community curation is the only viable way to keep that data accurate and up to date. The unification of OpenAlex and Unpaywall codebases means that all these changes will propagate to both systems within days.Ok, that’s all for now! Thanks for your support and as always, please get in touch with any suggestions or feedback!The post Unpaywall improvements: more gold, better green appeared first on OurResearch blog.

Gavin Newsom is expertly trolling Fox News stars by mimicking Trump online — right down to the nicknames
Justin Baragona: Over the past week, Gavin Newsom’s press office has been deliberately aping Donald Trump’s over-the-top social media posting style in an obvious attempt to not only troll the president’s most ardent defenders but also force them to come to grips with Trump’s bullying and bombastic tone.The pitch-perfect parody, which comes as the California governor goes on the attack against Trump while clearly eying a run for president, has also resulted in a number of Fox News stars taking the bait – and seemingly making Newsom’s point for him.“DANA ‘DING DONG’ PERINO (NEVER HEARD OF HER UNTIL TODAY!) IS MELTING DOWN BECAUSE OF ME, GAVIN C. NEWSOM!” the governor’s press office account tweeted on Tuesday. “FOX HATES THAT I AM AMERICA’S MOST FAVORITE GOVERNOR (

This was worse than the last time Trump met Zelensky. It was also deeply weird
Holly Baxter: After Friday’s red carpet love-in with Russian president Vladimir Putin, President Trump sat down with Ukrainian leader Volodymyr Zelensky today at the Oval Office to talk peace and the world hoped it would go better than the last White House meeting between the U.S. and Ukraine. Before meeting with Zelensky, or any other world leaders in town for the event, Trump was already telling reporters that peace could come “almost immediately” if Zelensky ditched NATO and gifted Putin Crimea - the diplomatic equivalent of telling someone to end a mugging by handing over their wallet and the deed to their house. Zelensky, of course, is a man in the awkward position of being the democratically elected leader of the country Trump’s friend is currently trying to dismantle. And the body language of today’s meeting told its own story: gone were the grinning asides and admiring jokes, replaced with the brittle civility of a man forced to pose with the victim while still swooning over the perpetrator.Zelensky, perched on the edge of his seat while Trump leaned back, opened by thanking Trump for arranging the meeting. Inevitably, he wore a suit rather than his signature military fatigues. Anyone who witnessed the horror of their last Oval Office encounter will recall how he was repeatedly chided by the president, J.D. Vance and far-right reporter Brian Glenn for not “suiting up.” Zelensky was also criticized for not being “grateful” enough — which explains why today he began by thanking Trump for arranging the meeting.Luckily for Zelensky and unluckily for the rest of us, it became clear that Trump wasn’t going to do a repeat performance of February’s attack — because he had other things on his mind anyway. Questions from the gathered media were direct: “Is today’s meeting ‘deal or no deal?’” asked one.Trump equivocated. “I can never say that.” What could he say, then? Well, it soon became unfortunately apparent.“This isn’t my war, this is Joe Biden’s war. He’s the one who —” There was a pause, where it seemed like the president was genuinely about to suggest that Biden started the war in Ukraine himself, before he ended up at “—had a lot to do with that happening.” No mention of Putin, of course. I mean, why would there be?And then it went on. And on, and on, and on. Asked directly about what was happening in Ukraine, Trump would wheel out an irritated, detail-free “We’re going to have lasting peace,” before going right back to his own agenda.Donald Trump spoke to reporters in the Oval Office alongside Ukrainian leader Volodymyr Zelensky. They started talking about peace - but then Trump meandered into his usual complaints. (REUTERS)“I used to get great publicity. Now I get the worst publicity that anyone’s ever had in office,” he said, after an unconnected question. Moments later, apropos nothing: “Joe Biden’s a very corrupt politician — not a smart man, by the way. Go back 40 years and he wasn’t smart then, either.” This tirade continued for a while, took a left turn into how the 2020 election was supposedly stolen from him, and ended with a Biden jab: “He was a horrible, corrupt president!” Zelensky had only minutes to talk about a one-and-a-half-year-old child who had just been killed in Kharkiv by Russian missiles.And Trump went right back to carrying on. Trump wants to end “corrupt” mail-in ballots and “the machines” (never mind the defamation lawsuits already lost by right-wing media spreading conspiracy theories about voting machines giving inaccurate results.) Mail-in voting is “a fraud” and “the Democrats want it because it’s the only way they get elected.” By the way, they also want “transgender for everybody.” And “they love crime”. Zelensky was, at this point, shifting a little uncomfortably in his chair. Utterly nonplussed, Trump continued. His freewheeling narrative alighted, for a second, on immigration: “In 90 days, not one person came in illegally to our country. Even I find that hard to believe!” And some more stuff about how the Democrats had let the southern border get out of control. A final question, attempting to get the president back onto a topic even remotely related to the Ukrainian leader seated opposite him, ended up with: “I love the Ukrainian people but I love all people. I love Russian people. I love them all.”This meeting, unlike February, didn’t have Oval Office confrontations. However, that didn’t mean it was better. (Samuel Corum/PA Wire)The stand-out moment was probably when Zelensky responded to a reporter’s question about why elections are difficult to arrange during active wartime, in terms of logistics. Having taken a while to explain how much extra security is needed, he then added that democratic elections in Ukraine would soon be arranged. And with a laugh, Trump said, “‘So you’re saying if we happen to be in a war with somebody, no more elections?” For any other politician, this might mark somewhat of a career low point. But of course today, under the Trump administration, it was just Monday.And so, somehow, Biden — who isn’t even in the room, who hasn’t been for months — became the central villain of the narrative, eclipsing both Putin and the ongoing missile strikes killing civilians. It’s a remarkable inversion: the man praising the aggressor, lecturing the victim and saving his deepest rage for his domestic rival. If you want to know what obsessions animate Trump’s foreign policy, don’t look to maps of Ukraine; look to the 2020 election.I’ll admit to believing that it couldn’t get worse than the school bully-style treatment of Zelensky last time he visited Washington, but this was worse. To listen to this press conference, you’d think Biden really was the one rolling tanks into Donetsk. A grievance recital that used the background of war for the foreground of Trump’s hurt feelings is so much less than what the world deserves.We all saw the red carpet on Friday, the festival-style “ALASKA 2026” and the photo-ops. We all saw the apathy today. Civilians die in Kharkiv, Europe flies in en masse to prop up Ukraine and Trump still finds a way to make the story about his ratings, his stolen thunder, his petty personal rants. If Friday was Broadway-style theater, today was a tragicomedy. And somehow, in the midst of war and mourning, the only thing that got center stage was Trump’s ego.

We’ve Located the Criminals in D.C.
Alexandra Petri: Thank goodness the National Guard is being called in. Lawlessness in D.C. is rampant, and someone needs to take a stand!Stephen Miller was correct to point out that D.C. is awash in crime. Everywhere he looks: criminals. He can barely take three steps without running into one. From the moment he arrives at work in the morning until the second he leaves, one crime after another, piling horrendously high. Illegality everywhere, and casual disregard for the well-being of law-abiding Americans!Some people say that being around crime is just the price of living in a city, and that those intimidated by it just need to toughen up. But it’s so brazen!Get off the Metro at any point in D.C., but especially near the White House, and you might encounter one of these miscreants, flaunting their impunity in broad daylight. Why isn’t law enforcement doing its job? Members of the violent January 6 mob, released back on the streets! A man who three whistleblowers alleged had told Department of Justice employees to ignore a court order and say “Fuck you” to a judge, headed to the federal bench! The people who dismantled the Department of Education, which had been established by an act of Congress, just wandering around!The Supreme Court ultimately decided the dismantling was okay, but the justices weren’t guaranteed to feel that way! There is a word for when you do something that seems illegal and just hope that a judge will let you off. But that’s the trouble with D.C. These judges are just giving slaps on the wrist for the most egregious offenses. And that invites more crime! Now, wherever Stephen looks, people are taking the Constitution as a mere suggestion. With judges like this, you could order SEAL Team Six to assassinate somebody, and you might get away with it. Who could feel safe in a city where that was true?Some madman recently filled the streets with weapons of war! Tanks! Actual tanks! Forget brandishing a gun in a public place—he insisted on tanks!Everywhere, there are people breaking the law, or trying to. Even the man Stephen works for turns out to be a convicted felon, who once said that “when you’re a celebrity, they let you do it.” He also urged a mob of people to descend on the Capitol “peacefully and patriotically.” Technically, not a crime but—an impeachable offense! He accepted a plane from Qatar. He stored classified documents in a bathroom! Never mind what his company was doing in New York State, or what E. Jean Carroll’s civil suit found. The things he is trying to do via executive order boggle the mind! And you should see his associates!The point is, crime is everywhere, if only you know where to look. Including in other neighborhoods of the city, but surely those crimes are best dealt with on a local level, and parachuting in federal law enforcement with an unclear mandate will only make the situation worse.Instead, the National Guard ought to focus on tackling the major terror on the streets of this city! Why, at any moment you or your neighbor could get yanked into an unmarked van by a masked man, without any regard for habeas corpus. Los Angeles all over again! How can anyone feel safe while this keeps happening? People who are trying to do everything the right way, snatched from hallways after their court hearings. Professors, detained after expressing their views. Americans who just want to work hard and support their families, petrified to go to work every day because of the shameless wrongdoers in D.C. and what they have unleashed. And whoever masterminded the abduction of so many people—seized without due process and whisked away to a foreign gulag—is still at large, and staring back at Stephen every time he looks into a mirror. Not safe, not safe!Thank goodness the National Guard is being called in. Lawlessness in D.C. is rampant, and someone needed to take a stand!Oh. Oh, I see. Never mind.About the AuthorAlexandra PetriAlexandra Petri is a staff writer at The Atlantic.
