🚨 Can we trust LLM-generated ontologies?
At #ESWC2026 / #llms4kgoe, I presented:
"Pitfalls in AI-Generated Ontologies: Strategies for Detection and Mitigation" where I discuss how to detect and mitigate common mistakes in AI-generated ontologies

Une étude (French et al., Information Systems Frontiers 2025) propose un modèle puissant pour comprendre comment nous consommons les fake news sur les réseaux sociaux.

Spoiler: ce n’est pas une question de crédulité. C’est une question d’émotions.

@claudeai @GeminiApp @ChatGPTapp @MistralAI @Alibaba_Qwen We released our best fine-tuned model, named PERSEUS. Benchmark results detailed at https://t.co/kfzG9dhfCz

Excited to have presented the Text2KGBench-LettrIA benchmark at the KB-LLM workshop at @iswc_conf. ~5k sentences annotated with respect to 19 ontologies to train #LLMs to build Knowledge Graphs.

We have then compared numerous closed LLMs (@claudeai @GeminiApp @ChatGPTapp) with fine-tuned open weights LLMs (@MistralAI @Alibaba_Qwen Gemma3, Phi4). There are clearly 2 leagues: fine-tuned specialized models OUTPERFORM larger closed models and are more efficient.
