Back in the lecture hall again after two exciting weeks of #ESWC2025 and #ISWS2025. This morning, we introduced our students to RDF, RDFS, RDF Inferencing, and RDF Reification.
#ise2025

Slide from the ISE 2025 lecture on Resource Descriptiuon Framework (RDF) as simple data model. The slide is showing a small knowledge graph, indicating that Climate Change was explained by Eunice Newton Foot in 1856 as well as by John Tyndall in 1859. To represent this n-ary (multi-valued) relations, we are using so-called blank nodes, representing an "explanation" each, which bundles the discoverer and the discovery date. This is done via "dereferencable" blank nodes here.

Good Morning ESWC2025! The last conference day is about to start. Looking forward to an interesting keynote, more presentations and interesting discussions! Most interesting to see for me this year was the presence of neurosymbolic topics almost everywhere in our community.

The background features a hilly landscape with a densely populated area, likely a town or city, characterized by numerous buildings and greenery. T…

LLMs are starving for knowledge graphs. Raphael Troncy was pointing out that many LLM company crawlers are constantly visiting their KGs. Some crawlers even perform explicit SPARQL queries on the KGs.

The image shows a presentation slide titled "LLMs are starving for KGs" (Large Language Models are starving for Knowledge Graphs). The slide is projected onto a screen and features a list of crawlers visiting various Knowledge Graphs (KGs), including OpenAI, ByteDance, Apple, Meta AI, Anthropic, Microsoft, DuckDuckGo, CommonCrawl, Amazon, and Perplexity. Each crawler is associated with a specific KG, and the number of requests made to each KG is listed. For example, OpenAI has made 3,430,585 re…
