Two intense days at the NFDI-MatWerk All-hands-on-Deck meeting in Siegburg! Huge kudos to the organising team for making it so fruitful. Loved connecting with the MatWerk community, reflecting on Phase 1 achievements and getting excited for Phase 2. Big shoutout to the @fizise team: @enorouzi @heikef Hossein Beygi Nasrabadi and Alsayed Algergawy!

Yesterday at the #SciLake closing event, we explored how the #SciLake project is helping turn fragmented scientific knowledge into more connected, discoverable insights through Scientific Knowledge Graphs.
We’ll be sharing highlights from the discussion soon.

📢 HMC FAIR Friday Seminar
More than a decade after the FAIR Principles were introduced, a key question remains:
👉 What value has FAIR actually delivered to researchers?
In this talk, Sebastian Hellmann and Jan Forberg explore the microeconomics of FAIR adoption and present open-source tools #Databus and #MOSS from the #DBpedia Association ecosystem.

@Ayenkantun found these pictures from 2011 at the XI Congreso Nacional de Software Libre (XI National Free Software Congress) in #LaPaz, #Bolivia. I talked about #OpenData and #KnowledgeGraphs. Between 2009 and 2011, I worked on Chilean open data projects regarding how to implement the active transparency law at the Ministry of Economy, the open data portal at the Ministry General Secretariat of the Presidency, and the political history knowledge graph at the Library of the National Congress.
We’re looking for a Research Knowledge Engineer (m/f/x) (full time, 3,5 years). If you have a #DigitalHumanities profile with experience in #Ontologies, #KnowledgeGraphs and #LinkedOpenData, then we’re looking for you! Boosts welcome.

Ontop 5.5.0 is out !
What's new?
- Supporting file names as table names greatly helps when working with Databricks, Apache Spark, and @duckdb .
- Time intervals
- Major improvements to the code, to ensure the software remains maintainable and well-performing in the future
Congratulations to all contributors who made this, again, a great release of @ontop .
SurrealDB v3 solves the graph RAG ugliness of a vector DB here, a graph DB there, a document store somewhere else. With native vectors, documents, and graph relations all in one engine, SurrealDB v3 finally gives a unified substrate for #GraphRAG. One query language. One data model. One place to store chunks, embeddings, entities, and edges.
But as an all‑in‑one platform for building #KnowledgeGraphs, it’s one of the most compelling options available today.
The complementary nature of #knowledgeGraphs and #LLMs has become clear and long-time knowledge engineering professionals like Quentin Reul now routinely combine them in hybrid #neurosymbolicAI systems.
While it's tempting to get caught up in the details of rapidly advancing AI technology, Quentin emphasizes the importance of always staying focused on the business problems your systems solve.
An instructive conversation. Hope you enjoy it too.
The Knwler hairball graph visualization (Cytoscape) has been replaced by a custom layout algorithm and SVG rendering.The layout now depicts much more clearly the relationships. The concentric circles and fading edges (proportional to distance) are organized according to degree and minimize crossings.
Hope you like it.

Memgraph 3.8 is here with real‑time graph intelligence.
Three things stand out:
- Atomic GraphRAG: graph augmented questions with one query.
- Vector Search in the Same Store: new hybrid graph‑vector patterns
- Parallel Runtime Improvements: analytical and traversal-heavy queries now run faster thanks to deeper parallelization across the runtime.
