  1. From raw statements to sound inference. This week's #KDAI2026 session works through the RDF stack top to bottom:
    ▸RDF — typed literals, blank nodes, and Turtle
    ▸RDFS — classes, domains & ranges, subClassOf hierarchies, model-theoretic semantics, reification & RDF*
    ▸SPARQL — first steps

    The triple is the message. 📡

  6. Ik zie dat de Nederlandse #overheid ( @Logius ) de #TOOI ontologieën en thesauri online te raadplegen heeft gemaakt via #ShowVoc. Heel cool!

    standaarden.overheid.nl/showvo

    Al deze informatie kan ook via een SPARQL-endpoint benaderd worden. En #WikiData federeert sinds kort met het TOOI SPARQL-endpoint.

  11. The new #KDAI2026 lecture is out. How to get from a sentence to something a machine can actually reason?

    The greenhouse effect was discovered by Fourier, explained by Eunice Newton Foote. 3 words, 1 triple: subject, predicate, object. Stack enough of them and you get a graph. Add an ontology and the machine starts to infer.

  16. this is amazing

    github.com/andjar/wikitiddler

    extracts data from multiple sources ( #Wikidata #SPARQL, JSON endpoints, RSS feeds ), converts the results to TiddlyWiki tiddlers with Python, builds a single-file #TiddlyWiki with Node.js, and deploys it to GitHub Pages — on a monthly schedule or on demand.

  21. C'est quand même plus pratique de faire des alignements en masse à partir de données ouvertes que de scrapper un site, nettoyer le résultat, aligner... 😇

    > Ajout de plus de 17000 identifiants #FranceArchives Agent sur #wikidata à partir des données #opendata

    > Ajout de la réutilisation (avec des exemples de requêtes #sparql) sur #datagouv :
    data.gouv.fr/reuses/alignement

  23. Strukturierte Daten auf #wikicommons sind ungemein nützlich. Mit ihnen lassen sich z.B. Bildinhalte strukturiert und (dank Linked Open Data) wunderbar maschinenlesbar erfassen und dann auch mit #SPARQL abfragen. Bilder von SPD-Mitgliedern des Weimarer Reichtstags? Kein Problem: qlever.dev/wikimedia-commons/d

    Die Ergänzung von entsprechenden Statements geht mit ein paar Tools relativ bequem. Wie, das habe ich hier beschrieben: commons.wikimedia.org/wiki/Use

    Gibt es da Bedarf an einer kurzen Live-Einführung?

  25. I had a lot of fun implementing a SPARQL editor for DanNet. During this process I also wrote a ton of new documentation, including a SPARQL tutorial that uses the new editor for its interactive examples.

    The idea is, of course, to make the Danish WordNet more broadly accessible. Previously, you would have had to spin up your own RDF triplestore to query DanNet using SPARQL.

  28. The joint plenary by #NFDI4Biodiversity and #NFDI4Earth continues with two Bar Camp style sessions with diverse topics contributed by the participants, pitched to the group, and magically ✨ turned into a programme.

    Great job by the organisers who made it possible that we provide an opportunity for anybody to share their work, questions and get new inputs.

  30. #wikidata est essentiel dans les projets #OpenData, notamment dans les institutions patrimoniales, qui ont tout intérêt à compléter des propriétés qui les concernent.

    Les requêtes #sparql permettent par exemple d'associer des images de provenance différentes dans une galerie, avec les liens vers l'institution d'origine.
    Voir aussi la somme de toutes les #peintures.
    Il existe 2300 catalogues construits à partir de requêtes dans #wikidata, des listes d'#expositions...

  31. @daieuxetdailleurs

    Le rêve : répercuter les données sur #wikipedia et avoir des données intégrales sur préfets, sous-préfets, secrétaires...

    On peut effectuer des requêtes en #sparql, en utilisant resonator pour une visualisation plus didactique, avec notamment une frise chronologique : voir histropedia pour les préfets de l'Aube.
    Merci au roi de la requête @belett 😁

    Elle ajoute aussi des #signatures et des #portraits sur #wikicommons

    Bravo pour cette intervention 👏

  32. [#wikidata #archives] Mise à jour des données du budget des #archivesdepartementales 2017-2020 (après ça ne figure plus dans les données sur #FranceArchives )

    Requête #SPARQL pour la #Bretagne :bretagne: : w.wiki/CgS$

    Une idée pour le pic 2018 des #AD44 🤔 ?! (pour les #AD22, c'est le nouveau bâtiment > chantiers des fonds, reconditionnement, etc)
