A new arXiv paper introduces CITECHOICE, a causal audit framework for studying citation allocation in multi-turn agentic search, where an answer engine cites only some of the retrieved sources that support the same claim. The study is built from 129 everyday queries and examines how the way documents are presented redistributes credit among sources.
A new arXiv paper addresses the problem that citations attached to LLM answers in clinical question answering usually reference whole documents, which makes verification slow for busy clinicians. The authors propose an evaluation approach that works at the level of individual claims, requiring verbatim citation support that can be checked directly. The stated goal is to make system outputs verifiable by construction rather than by trust.
A new arXiv paper examines how context compression in retrieval-augmented generation affects citation attribution, not just answer quality. The authors benchmark reranking and extractive compression approaches under varying compression budgets to map what they call the attribution-compression frontier. The work suggests that evaluating answer accuracy alone misses important degradation in source attribution.
A new arXiv paper describes "citation laundering," where retrieval-augmented generation systems surface citations that appear legitimate but do not actually support the claims they are attached to, weakening the audit trail users rely on. The authors propose a counterfactual defense aimed at detecting and mitigating this manipulation across multiple retrieved sources. The work sits in the cs.CL area and is listed as a cross-list announcement.
A new arXiv paper presents CiteGuard-RAG, a retrieval-augmented generation system built around validating answers rather than only retrieving supporting passages. The authors argue that fetching evidence does not by itself guarantee that responses are properly grounded, carry valid citations, or are refused when appropriate. The work proposes a validation-focused design intended to enforce those checks.
