Lookahead Citation Placement: Predicting Where Citations Are Needed to Support Individual Claims and Preserve Readability

Academic writing requires not only identifying relevant publications but also determining which claims require citations, where citation markers should be placed, and how supporting evidence should be distributed across a document without unnecessarily interrupting readability. Conventional citation recommendation methods primarily focus on identifying relevant publications for a given text passage, while evidence-grounded generation approaches have explored the integration of source attribution into the generation process. However, the relationship between citation placement and the downstream quality of an entire explanation provides an additional decision problem: a citation placement that appears locally appropriate may leave a neighboring claim unsupported, create redundant attribution, or interrupt the logical flow of an argument. This paper proposes Lookahead Citation Placement (LCP), a conceptual framework for predicting the consequences of alternative citation placements before committing to a final citation arrangement. Given a draft containing multiple claims and a collection of verified candidate sources, LCP identifies citation-worthy claims, generates alternative placement configurations, estimates their effects on evidential coverage, claim–source alignment, readability, redundancy, and verification cost, and selects a configuration with the highest predicted utility under a computational budget. The framework distinguishes the decision of whether a claim needs support from the decisions of which source supports it and where the corresponding citation marker should appear. It also incorporates uncertainty-aware selection, claim-level evidence verification, document-level optimization, and optional feedback-based learning. A mathematical formulation, training objectives, inference algorithm, and experimental protocol are presented. The proposal is designed to complement existing citation recommendation, attributed text generation, and evidence-grounded generation methods rather than replace them. No experimental results are claimed. The effectiveness and novelty of LCP must be established through controlled comparisons, particularly against methods that detect unsupported claims and insert citations after drafting.
