We are happy to announce an update to our article “Semantic Web: Past, Present, and Future”, published in TGDK 2(1): 3:1–3:37 (2024). ✨ The article has been extended with learning methods on knowledge graphs and language models and knowledge graphs. 🤖📚 🔗 lnkd.in/eDNDYSp5 Feedback is very welcome! 💬

An interesting new paper on the Distances Between Formal Concept Analysis Structures just published in @tgdkjournal.bsky.social See: drops.dagstuhl.de/entities/doc...

I wonder how many conferences taking place this year in the US will be online only / in parts virtual because of what is going on there - Or to put it in MeidasTouch's Tennessee Brando's words, "America Is Now a Dictatorship", see substack.com/inbox/post/1...

When Springer renames a journal from IR to "Discover Computing", it sucks! Now it looks like our article with @lukasgalke.bsky.social and Iacopo Vagliano appeared in there. I don't even know what "Discover Computing" is, nor does my AI-companion. Stop doing this. The journal impact factor is now 0.

Thank you, we still have sane people in the US! @meidastouch.com Now it is time for US research institutions to stand up! @columbiauniversity.bsky.social you can do better! Make Ron happy!

In the US, classes are back online — not due to a pandemic, but because students fear being snatched off the street and deported 😟📚 Meanwhile, in Germany, some still act like it’s a game To students & scholars: you’re welcome here. To Europe’s academics: wake up. This is not a drill. ⏰🌍 #50501

The AI that DOGE allegedly uses is obviously a simple list of regular expressions (aka a Gazetteer approach) and aims to delete all web content, fire all people, etc., that match on trans*, gay*, dei * ... see also the "Enola Gay" story, www.youtube.com/watch?v=CQ90...

📢 A major tech-related legal case is back in the spotlight! A well-documented scandal in the British Post Office—caused by programming errors—led to serious miscarriages of justice. Great to see *Comm. of the ACM* covering this important issue in their latest edition. cacm.acm.org/news/how-sof...

American scientists, come to Europe! 🌍✈️ We all speak English, we have excellent affordable health care 🏥💊, safe schools 🏫🔒, and free university education for your kids 🎓👨‍👩‍👧‍👦. Enjoy more money after deduction of taxes and living expenses 💰📉. We care for you! ❤️🤝 www.youtube.com/watch?v=9_l0...

When fact's don't matter anymore, you end up with Elon and Donald. -

German public news authority @tagesschau.de.web.brid.gy's front page calls the Trump government by the right words: dictatorship and coup. As a researcher, I need unfiltered facts. I deleted the @cnn.com app weeks ago. Tune in to Prof @meiselasb.bsky.social and @meidastouch.com Src:

After people have left X, they will also leave Facebook after this move. Luckily, not many researchers are actively pushing research content on FB anyway. So I won't care :-) @thebulwark.bsky.social www.thebulwark.com/p/mark-zucke...

Preventing catastrophic forgetting in NLP! 🌟 Our discrete key-value bottleneck enables efficient continual learning in encoder-only language models—no major updates, just localized tweaks. With Andor Diera and @lukasgalke.bsky.social Learn more! 🚀 arxiv.org/abs/2412.08528

Standard GNNs excel on homophilic graphs but depend on neighborhood patterns. ES-MLP, a student project by Matthias Kohn and co-supervised with Marcel Hoffmann, presented at #log2024, combines Graph-MLP with edge-splitting for faster, robust, edge-free inference. openreview.net/forum?id=BQE...

Hierarchical Text Classification (HTC) vs. eXtreme Multilabel Classification (XML) are two research areas that have been disconnected so far. A team of students and with @lukasgalke.bsky.social we show that it is crucial to cross the two worlds. Read more arxiv.org/abs/2411.13687

I grew up with Twitter, me and my academic life. We used it at conferences, saw it struggle financially & wondered if it’d survive. I never imagined a billionaire would buy it for $44B, overrun it, & turn it into a hate platform. Now, Twitter-based research is part of scientific history?

Hierarchical text classification does not need a graph encoder or label semantics. Work at the European Conference on Artificial Intelligence 2024 (ECAI) by Yousef Younes and with @lukasgalke.bsky.social - learn more: ebooks.iospress.nl/doi/10.3233/...

... but it would be no fun if I just left X without saying anything further. From now on, I will advertise all my messages on Mastodon, BlueSky, and LinkedIn with a link from X and encourage people to move on and turn the page. Meanwhile, my X account is labeled as (legacy account) 😛 Elon

I decided weeks ago to leave Twitter, prepared it, and now it is done. So many others have done so by now, too.
