The new AI Risk โ€œontologyโ€: A Map with No Rules
The new AI Risk โ€œontologyโ€: A Map with No Rules
A Map with No Rules The new AI Risk โ€œontologyโ€ (AIRO) maps regulatory concepts from the EU AI Act, ISO/IEC 23894, and ISO 31000. But without formal constraints or ontological grounding in a top-level ontology, it reads more like a map with no rules. At first glance, AIRO seems well-structured. It defines entities like โ€œAI Provider,โ€ โ€œAI Subject,โ€ and โ€œCapability,โ€ linking them to legal clauses and decision workflows. But it lacks the logical scaffolding that makes semantic models computable. There are no disjointness constraints, no domain or range restrictions, no axioms to enforce identity or prevent contradiction. For example, if โ€œProviderโ€ and โ€œSubjectโ€ are just two nodes in a graph, the system has no way to infer that they must be distinct. Thereโ€™s nothing stopping an implementation from assigning both roles to the same agent. Thatโ€™s not an edge case. Itโ€™s a missing foundation. This is where formal ontologies matter. Logic is not a luxury. Itโ€™s what makes it possible to validate, reason, and automate oversight. Without constraints and grounding in a TLO, semantic structures become decorative. They document language, but not the conditions that govern responsible behavior. If we want regulations that adapts with AI instead of chasing it, we need more than a vocabulary. We need logic, constraints, and ontological structure. #AIRegulation #ResponsibleAI #SemanticGovernance #AIAudits #AIAct #Ontologies #LogicMatters

Graph Learning Will Lose Relevance Due To Poor Benchmarks
Graph Learning Will Lose Relevance Due To Poor Benchmarks
๐Ÿ“ฃ Our spicy ICML 2025 position paper: โ€œGraph Learning Will Lose Relevance Due To Poor Benchmarksโ€. Graph learning is less trendy in the ML world than it was in 2020-2022. We believe the problem is in poor benchmarks that hold the field back - and suggest ways to fix it! We identified three problems: #๏ธโƒฃ P1: No transformative real-world applications - while LLMs and geometric generative models become more powerful and solve complex tasks every generation (from reasoning to protein folding), how transformative could a GNN on Cora or OGB be? P1 Remedies: The community is overlooking many significant and transformative applications, including chip design and broader ML for systems, combinatorial optimization, and relational data (as highlighted by RelBench). Each of them offers $billions in potential outcomes. #๏ธโƒฃ P2: While everything can be modeled as a graph, often it should not be. We made a simple experiment and probed a vanilla DeepSet w/o edges and a GNN on Cayley graphs (fixed edges for a certain number of nodes) on molecular datasets and the performance is quite competitive. #๏ธโƒฃ P3: Bad benchmarking culture (this one hits hard) - itโ€™s a mess :) Small datasets (donโ€™t use Cora and MUTAG in 2025), no standard splits, and in many cases recent models are clearly worse than GCN / Sage from 2020. It gets worse when evaluating generative models. Remedies for P3: We need more holistic benchmarks which are harder to game and saturate - while itโ€™s a common problem for all ML fields, standard graph learning benchmarks are egregiously old and rather irrelevant for the scale of problems doable in 2025. ๐Ÿ’ก As a result, itโ€™s hard to build a true foundation model for graphs. Instead of training each model on each dataset, we suggest using GNNs / GTs as processors in the โ€œencoder-processor-decoderโ€ blueprint, train them at scale, and only tune graph-specific encoders/decoders. For example, we pre-trained several models on PCQM4M-v2, COCO-SP, and MalNet Tiny, and fine-tuned them on PascalVOC, Peptides-struct, and Stargazers to find that graph transformers benefit from pre-training. --- The project started around NeurIPS 2024 when Christopher Morris gathered us to discuss the peeve points of graph learning and how to continue to do impactful research in this area. I believe the outcomes appear promising, and we can re-imagine graph learning in 2025 and beyond! Massive work with 12 authors (everybody actually contributed): Maya Bechler-Speicher, Ben Finkelshtein, Fabrizio Frasca, Luis Mรผller, Jan Tรถnshoff, Antoine Siraudin, Viktor Zaverkin, Michael Bronstein, Mathias Niepert, Bryan Perozzi, and Christopher Morris (Chris you should create a LinkedIn account finally ;)

Lessons Learned from Evaluating NodeRAG vs Other RAG Systems
Lessons Learned from Evaluating NodeRAG vs Other RAG Systems
๐Ÿ”Ž Lessons Learned from Evaluating NodeRAG vs Other RAG Systems I recently dug into the NodeRAG paper (https://lnkd.in/gwaJHP94) and it was eye-opening not just for how it performed, but for what it revealed about the evolution of RAG (Retrieval-Augmented Generation) systems. Some key takeaways for me: ๐Ÿ‘‰ NaiveRAG is stronger than you think. Brute-force retrieval using simple vector search sometimes beats graph-based methods, especially when graph structures are too coarse or noisy. ๐Ÿ‘‰ GraphRAG was an important step, but not the final answer. While it introduced knowledge graphs and community-based retrieval, GraphRAG sometimes underperformed NaiveRAG because its communities could be too coarse, leading to irrelevant retrieval. ๐Ÿ‘‰ LightRAG reduced token cost, but at the expense of accuracy. By focusing on retrieving just 1-hop neighbors instead of traversing globally, LightRAG made retrieval cheaper โ€” but often missed important multi-hop reasoning paths, losing precision. ๐Ÿ‘‰ NodeRAG shows what mature RAG looks like. NodeRAG redesigned the graph structure itself: Instead of homogeneous graphs, it uses heterogeneous graphs with fine-grained semantic units, entities, relationships, and high-level summaries โ€” all as nodes. It combines dual search (exact match + semantic search) and shallow Personalized PageRank to precisely retrieve the most relevant context. The result? ๐Ÿš€ Highest accuracy across multi-hop and open-ended benchmarks ๐Ÿš€ Lowest token retrieval (i.e., lower inference costs) ๐Ÿš€ Faster indexing and querying ๐Ÿง  Key takeaway: In the RAG world, itโ€™s no longer about retrieving more โ€” itโ€™s about retrieving better. Fine-grained, explainable, efficient retrieval will define the next generation of RAG systems. If youโ€™re working on RAG architectures, NodeRAGโ€™s design principles are well worth studying! Would love to hear how others are thinking about the future of RAG systems. ๐Ÿš€๐Ÿ“š #RAG #KnowledgeGraphs #AI #LLM #NodeRAG #GraphRAG #LightRAG #MachineLearning #GenAI #KnowledegGraphs

๐Ÿ“ฃ Byte #21: For those of you who want to visualize their graphs inside Jupyter notebooks - we have an exciting development! We recently released an integration with yWorks, who extended their yFiles Jupyter Graphs widget to support Kuzu databases! โœ… Once a Kuzu graph is created, we can instantiate the yFiles Jupyter KuzuGraphWidget, and use the `show_cypher` method to display a subgraph using regular Cypher queries. โœ… There are numerous custom layouts in the yFiles widget (tree, hierarchical, orthogonal, etc.). Give them a try! Here's an example of the tree layout, which is great for visualizing data like this that has rich tree structures. We can see the two-degree mentors of Christian Christiansen, a Nobel prize-winning laureate, in this example. โœ… You can customize the appearance of the nodes in the widget through `add_node_configuration` method. This way, you can display what you're looking for as you iterate through your graph building process. โœ… The Kuzu-yFiles integration is open source and you can begin using it right away for your own interactive visualizations. Give it a try and share around with fellow graph enthusiasts! pip install yfiles-jupyter-graphs-for-kuzu Docs page: https://lnkd.in/g97uSKRe GitHub repo: https://lnkd.in/gjA6ZjiF

RDF-specific functionality for VS Code
A little peek into our developments of RDF-specific functionality for VS Code: 1๏ธโƒฃ The autocompletion and hover-help for RDF vocabularies. Some are stored within the VS Code plugin, the rest are queried from LOV, giving intellisense to the most prominent ontologies. 2๏ธโƒฃ We can use the ontology of the vocabularies to show when something is not typed correctly 3๏ธโƒฃ SHACL has a SHACL meta-model. As we built a SHACL engine into VS Code, we can use this meta model to hint if something is not done correctly (e.g., a string as part of a datatype). We plan to release the plugin to the marketplace in some time (However, we are still building more functionality). To not take too much credit: https://lnkd.in/eFB2wKdz delivers important features like most syntax highlighting and auto-import of the prefixes.

What if your LLM isโ€ฆ a graph?
What if your LLM isโ€ฆ a graph?
What if your LLM isโ€ฆ a graph? A few days ago, Petar Veliฤkoviฤ‡ from Google DeepMind gave one of the most interesting and thought provoking conference I've seen in a while, "Large Language Models as Graph Neural Networks". Once you start seeing LLM as graph neural network, many structural oddities suddenly falls into place. For instance, OpenAI currently recommends to put the instructions at the top of a long prompt. Why is that so? Because due to the geometry of attention graphs, LLM are counter-intuitively biased in favors of the first tokens: they travel constinously through each generation steps, are internally repeated a lot and end up "over-squashing" the latter ones. Models then use a variety of internal metrics/transforms like softmax to moderate this bias and better ponderate distribution, but this is a late patch that cannot solve long time attention deficiencies, even more so for long context. The most interesting aspect of the conference from an applied perspective: graph/geometric representations directly affect accuracy and robustness. As the generated sequence grow and deal with sequences of complex reasoning steps, cannot build solid expert system when attention graphs have single point of failures. Or at least, without extrapolating this information in the first place and providing more detailed accuracy metrics. I do believe LLM explainability research is largely underexploited right now, despite being accordingly a key component of LLM devops in big labs. If anything, this is literal "prompt engineering", seeing models as nearly physical structure under stress and providing the right feedback loops to make them more reliable. | 30 comments on LinkedIn

Choosing the Right Format: How Knowledge Graph Layouts Impact AI Reasoning
Choosing the Right Format: How Knowledge Graph Layouts Impact AI Reasoning ... ๐Ÿ‘‰ Why This Matters Most AI systems blend knowledge graphs (structured data) with large language models (flexible reasoning). But thereโ€™s a hidden variable: "how" you translate the graph into text for the AI. Researchers discovered that the formatting choice alone can swing performance by up to "17.5%" on reasoning tasks. Imagine solving 1 in 5 more problems correctly just by adjusting how you present data. ๐Ÿ‘‰ What They Built KG-LLM-Bench is a new benchmark to test how language models reason with knowledge graphs. It includes five tasks: - Triple verification (โ€œDoes this fact exist?โ€) - Shortest path finding (โ€œHow are two concepts connected?โ€) - Aggregation (โ€œHow many entities meet X condition?โ€) - Multi-hop reasoning (โ€œWhich entities linked to A also have property B?โ€) - Global analysis (โ€œWhich node is most central?โ€) The team tested seven models (Claude, GPT-4o, Gemini, Llama, Nova) with five ways to โ€œtextualizeโ€ graphs, from simple edge lists to structured JSON and semantic web formats like RDF Turtle. ๐Ÿ‘‰ Key Insights 1. Format matters more than assumed: ย ย - Structured JSON and edge lists performed best overall, but results varied by task. ย ย - For example, JSON excels at aggregation tasks (data is grouped by entity), while edge lists help identify central nodes (repeated mentions highlight connections). 2. Models donโ€™t cheat: Replacing real entity names with fake ones (e.g., โ€œFranceโ€ โ†’ โ€œVerdaniaโ€) caused only a 0.2% performance drop, proving models rely on context, not memorized knowledge. 3. Token efficiency: ย ย - Edge lists used ~2,600 tokens vs. JSON-LDโ€™s ~13,500. Shorter formats free up context space for complex reasoning. ย ย - But concise โ‰  always better: structured formats improved accuracy for tasks requiring grouped data. 4. Models struggle with directionality: ย  Counting outgoing edges (e.g., โ€œWhich countries does France border?โ€) is easier than incoming ones (โ€œWhich countries border France?โ€), likely due to formatting biases. ๐Ÿ‘‰ Practical Takeaways - Optimize for your task: Use JSON for aggregation, edge lists for centrality. - Test your model: The best format depends on the LLMโ€”Claude thrived with RDF Turtle, while Gemini preferred edge lists. - Donโ€™t fear pseudonyms: Masking real names minimally impacts performance, useful for sensitive data. The benchmark is openly available, inviting researchers to add new tasks, graphs, and models. As AI handles larger knowledge bases, choosing the right โ€œdata languageโ€ becomes as critical as the reasoning logic itself.
