Today in the ISE 2025 lecture on OWL, the Web Ontology Language. Tired of using slide presentations (at temperatures like today and giving the same presentation all over again), I spontaneously decided to design arbitrary OWL ontologies together with the students on the good old blackboard ;-)

#SPARQL query selecting all statements:

sparql.org/sparql?query=SELECT

```
SELECT *
FROM <rdf.greggkellogg.net/distiller>
WHERE {
?s ?p ?o.
}
```

778 specific citations based on Citation Type Ontology. This is not just "document cites document" but specific thing within cites another specific thing elsewhere on the web).

sparql.org/sparql?query=SELECT

```
SELECT *
FROM <rdf.greggkellogg.net/distiller>
WHERE {
?s ?p ?o.
FILTER STRSTARTS(STR(?p), "purl.org/spar/cito/")
}
```

@lysander07 What I like about this view is that info is not necessarily complete. Typical real-world data. So, some queries will not show everything there is to know about a topic while a lot of info may be for other things. Though it can be extended - "pay as you go".

Some students may also be interested in expressing their research output as a #KnowledgeGraph on its own right - playing an important role in #ScholarlyCommunication

eg view: dokie.li/?graph=https://csarve

seeAlso alt text.

#ISE2025

Graph view of http://csarven.ca/linked-research-decentralised-web based on underlying structured data (in RDFa) with legend expressing number of statements (3148) and uniqur nodes (2022), as well as information about the tool generated it ( https://dokie.li/ ) and the license (CC BY 4.0). The graph depicts connected nodes in different colours, with their general class, internal/external references, citations, social connections, datasets, requirements, advisements, specifications, policies, events, slides, and concepts.

VUB 🇧🇪 is hunting for a #postdoc / #Research Engineer who vibes with #nlp + ontologies.

We juggle:
💻 Python & transformers
🗂️ #ontology craft
🔍 #knowledgegraph wizardry

Partial remote? Totally cool.

DM me if you’re curious — and feel free to boost! 🚀 #NLP #semanticweb

In the next tutorial, Lise Stork from University of Amsterdam and Stefano di Grigoris from VU Amsterdam are introducing us into Ontology and Knowledge Modeling.

Cartographier les façons de modéliser les tags

forum.openstreetmap.fr/t/carto

#openstreetmap #pim #knowledgeGraph #triplets

Pour documenter les différentes façons générales d’articuler des tags et aider les personnes qui souhaitent se lancer dans la création ou l’amélioration de modèles de tags, je me disais qu’il serait bien de formaliser les quelques façons générales de faire, et de mettre ça dans une page du wiki. J’avais commencé une ébauche dans la page Anatomie des étiquettes OSM, mais je me dis que ça a peut être déjà été réfléchi ailleurs, peut être sous d’autres noms (du typage de variable?). Nous n’avons ...

Anhand von Opernaufführungen aus dem Portal Partitura des #DHI #Rom zeigt Torsten Schrade die Integration von römischen #Kulturdaten in den #KnowledgeGraph von #NFDI4Culture

💻 partitura.dhi-roma.it/

💡 Mithilfe von Datenföderation bzw. #LinkedOpenData wird es möglich, Vergleiche von Kulturdaten untereinander anzustellen und so ganz neue Forschungsperspektiven zu eröffnen ‼️

Dear registered students for ISWS 2025, please keep in mind that the deadline for the poster submission is not far away...
We are looking forward to your submissions!

#isws2025 #summerschool #semanticweb #semweb #llm #nlp #knowledgegraph #AI #responsibleAI #reliableAI @sourisnumerique @lysander07

Poster of the ISWS 2024 summer school. The image is of a poster affixed to a fence, highlighting topics related to scientific research. The poster discusses the "VIEWSARI Knowledge Graph 1.0" and references Giorgio Vasari's perspectives on his new renaissance in art and science. There seems to be a focus on ontology mapping within this context as well as recognition of works related to different figures or concepts such as Panoisky's theories or methodologies (referred to as lemeks). The overall theme suggests an evolution or advancement in understanding scientific knowledge through a graphical representation, emphasizing both historical and contemporary insights into various works recognized within this field.

Got a #knowledgegraph want some use cases and example queries and how to share them: Read our paper in GigaScience academic.oup.com/gigascience/a Join us in #SPARQLing your #SPARQL to improve your #SPARQL ;)

What does it mean "to know" something? Have you ever thought about it? We tried to make our students think about it in this week's first #ise2025 lecture.

The image features a digital representation of a human face composed of yellow and orange alphanumeric characters, set against a dark background. The face is centrally positioned, with the eyes closed, and the text "What is Knowledge?" prominently displayed at the top in large, bold, yellow font. Below the face, three statements are presented in white text: "I know that climate change is man made," "I believe that climate change is man made," and "It is true that climate change is man made." The background is filled with vertical streams of yellow alphanumeric characters, resembling a digital rain effect, which adds a technological and data-driven atmosphere to the image. The overall color scheme is dark with contrasting yellow and white text, emphasizing the central theme of knowledge and its relationship to climate change.
