Knowledge-Graph Based Augmentation versus Retrieval Augmented Generation for Cultural-Related Question Answering

Pablo Poulenard, Yannis Karmim, Valentin Barrière

Large language models (LLMs) suffer from a long-tail deficit: culturally specific facts, particularly those concerning underrepresented regions such as Latin America, appear too ra…

Multi-Hop Knowledge Composition is Bound by Pretraining Exposure

Yannis Karmim, Luis Marti, Djamé Seddah +1

Large Language Models fail at implicit multi-hop reasoning: a model answers "When was born?" and "Who is 's closest friend?" correctly but fails on "When was 's closest f…
