Tracing Recurrent and Emergent Hallucination Patterns in Decomposed Text-to-SQL Generation

Read the original on arXiv Computation and Language →

The paper introduces a drill‑down evaluation framework that breaks down Text‑to‑SQL queries into simpler executable sub‑queries and natural‑language questions, enabling analysis of hallucination patterns along the generation path. It distinguishes recurrent hallucinations—those appearing in both early and final steps—from emergent hallucinations that only surface at the end. Experiments on five large language models and an expanded BIRD‑mini benchmark reveal varying recurrence and emergence probabilities across categories, with conversational history generally increasing recurrence and decreasing emergence.

Not All Needles Are Found: How Fact Distribution and Don't Make It Up Prompts Shape Retrieval, Reasoning, and Hallucination in Long-Context LLMs

arXiv:2601. 02023v2 Announce Type: replace-cross Abstract: As Large Language Models (LLMs) increasingly utilize massive context windows as working memory for autonomous tasks, their reliability fluctuates significantly depending on how information is distributed in real-world corpora.

DialFork: Going Beyond Factuality to Evaluate Procedural Hallucination in Conversational Agents

DialFork is a new benchmark that evaluates procedural hallucination in conversational agents, a failure mode where agents produce fluent, factually plausible utterances but deviate from the intended dialogue process. The benchmark consists of 36,278 dialogues across 24 tasks in 12 domains, created by forking conformant dialogues and injecting one of four hallucination types, with validation by 30 human annotators. Three evaluation tasks are defined—monitoring overall deviation, procedural retrieval of a single dialogue, and real‑time detection of off‑track turns—using dialog‑flow‑aware metrics FlowKL and FlowScore, which outperform baseline semantic similarity metrics.
