The CIA World Factbook has been a reference work for many, including Wikipedia for many years. It's been killed. Just like that. But facts still matter! Can we rebuild something better on top of @wikidata? Hit me up if you're interested!

We are happy to welcome our new colleague Rafael Petronilo in our FIZ KDAI research team! Rafael originally comes from Portugal and is an expert in deep learning and knowledge graphs and we are very much looking forward to collaborate with him. He will be supporting our BMF project "Themenportal Wiedergutmachung nationalsozialistischen Unrechts"

Rafael standing in front of our grass world map in the FIZ Karlsruhe World Café. 🗨️Here's what Rafael himself says about his new job:
!I am excited to join FIZ as a PhD student and for the opportunity to work with this team. I have been fascinated by the concept of AI from a very young age. While growing up, it was exciting to see the technology evolve and how the line between science fiction and reality started blurring in the field. I aspire to be able to contribute to the further development of AI technologies. At the university, I did a bachelor's and master's degree in Computer Science and Engineering, focusing on multiple different AI topics, among which deep learning, natural language processing, neurosymbolic AI, explainable AI, knowledge representation, and automated reasoning. Now I wish to continue working towards pursuing an AI-focused research career. I think in the ISE department at FIZ I will have the opportunity to work with and learn from incredible people, facing new interesting challenges and finding innovative ways to tackle them."

The Data Shapes Working Group has published a First Public Working Draft of SHACL 1.2 Node Expressions. This document describes Shapes Constraint Language (SHACL) Node Expressions. This specification is part of the SHACL 1.2 family of specifications.
https://www.w3.org/news/2026/first-public-working-draft-shacl-1-2-node-expressions/

The following example contains a node expression that states that the target nodes of the shape ex:EstonianCompanyShape are the instances of ex:Company where the ex:headQuarterCountry is ex:Estonia.
Example 1: A node expression used to compute the target nodes of a shape.

ex:EstonianCompanyShape

sh:targetNode [
shnex:nodes [
shnex:instancesOf ex:Company ;

shnex:filterShape [

Stranded in Fulda thanks to winter vs Deutsche Bahn. Luckily, I‘ve found a cozy Café 😋 to shorten my waiting.

Yesterday, I had the honor to deliver an invited talk with the title "Convenience vs Competence: the Evolving Role of Foundational Knowledge in AI-Driven Research" at the new year's receiption of the computer science faculty at Friedrich-Schiller-Universität Jena. Very happy to be at the place again, where I did my first PostDoc more than 20 years ago and meeting many old friends. :)

Gestern haben @marcuwekling und @linuzifer den Digital Independence Day #diday #didit #did auf dem #39c3 ausgerufen - an jedem ersten Sonntag im Monat wechselt man auf einen datensouveränen Anbieter. Von X zu #Mastodon, von Insta zu #Pixelfed - you get the idea. Wichtig: damit dann auch laut angeben. Dazu gibt es natürlich eine #mastowall:

By chance I've just discovered my 2021 keynote at the GNDCon 2.0 (not as usual at the German National Library in Frankfurt, but online due to COVID19) entitled "Die Welt ist klein und man trifft sich immer zweimal..." (It's a small world and you always meet twice...)

Today at VU Amsterdam for the PhD defense of Shuai Wang. I really liked the traditional and formal procedure in the Netherlands how they conduct a PhD defense and the subsequent investiture of the new PhD.

#PhD #academiclife #Amsterdam @vuamsterdam #AI #knowledgegraphs #semanticweb @fizise @fiz_karlsruhe

PhD defense of Shuai Wang at VU Amsterdam. They really have a rather "traditional" procedure :wink: The picture was taken after the investiture of the newly promoted PhD in front of the bust of the founder of VU. FYI: the head of the committee is the professor with the chain around his neck. Only full professors are allowed to wear gown and hat. The candidate chose to wear traditional formal Mongolian clothing (traditional local clothing from your home country - besides wearing a black formal attire - is recommended in the official dresscode for the candidate). Probably you will recognize Frank van Harmelen (the official supervisor), Aidan Hogan (besides me the other external reviewer), Jacco van Ossenbruggen (the forth professor), Wouter Beek and Illaria Tidi (external reviewers but not full professors), and Peter Bloem (the direct day-to-day supervisor, being an assistant professor). There are two guys in white tie cutaways in the back, who are the "paranymphs" (aka assistants) of the PhD candidate (in old times, they were allowed to wear a sword, and to defend the candidate against (sword) attacks of the opponent professors, which might occur in heavy academic dispute :wink: )

Besides others, he is demonstrating that our #nfdicore ontology is registered at Semantic Farm (= an open source, domain-agnostic, community curated semantic space registry, meta-registry, and compact identifier resolver.)

Conceptual Overlap, Redundancies, and Discrepancies
referring to
a) Redundancies due to same subject (e.g., aspirin) between ChEBI. DrugBank, and PubMed
b) Redundancies due to different topic specificity (as e.g. between IDOMAL, IDOCOVID19, CIDO, VIDO, etc.)
c) Redundancies from highly generic resources (UMLS, MESG, NCIT)
