Hallucination Detection in Structured Query Generation via LLM Self-Debating

EMNLP 2025

Hallucination remains a key challenge in applying large language models (LLMs) to structured query generation, especially for semi-private or domain-specific languages underrepresented in public training data. In this work, we focus on hallucination detection in these low-resource structured languag

Enhancing Hyperbolic Knowledge Graph Embeddings via Lorentz Transformations

ACL 2024findings

Knowledge Graph Embedding (KGE) is a powerful technique for predicting missing links in Knowledge Graphs (KGs) by learning the entities and relations. Hyperbolic space has emerged as a promising embedding space for KGs due to its ability to represent hierarchical data. Nevertheless, most existing hy…
