Scientific posters improved by persistent control using semantic contracts

From Transient Prompts to Persistent Control: Scientific Poster Generation via Recursive Semantic-Geometric Contracts

Artificial Intelligence

Summary

Creating scientific posters involves fitting a lot of information into one page in a clear way, which is tricky. The researchers developed PosterVisor, a system that keeps track of all requirements from a paper and its visuals in a consistent way, avoiding mistakes that happen when plans change during the process. This system checks the poster at different steps and fixes issues without causing new problems. They tested it on a set of 100 papers and found it produced better posters than previous methods, as confirmed by both automated tests and human preferences.

What this means in practice

  • For scientific communication teams: Automatically generate posters summarizing research papers with improved accuracy and visual consistency using persistent control contracts.
  • For conference organizers: Produce clearer and more reliable research posters for presentations by applying recursive contract enforcement throughout poster creation.

Abstract

Scientific poster generation distills a multimodal paper into a single-page visual artifact, forcing strict trade-offs between informational coverage and readability under a fixed spatial budget. Existing methods pass plans as transient prompts and validate individual stages in isolation. This strategy causes requirements to drift across content and layout modules, and previous checks to be silently invalidated. We introduce PosterVisor, a control framework that shifts poster generation from transient prompts to persistent control. An Orchestrator grounds rubrics in the paper and visual assets, compiling them into a Semantic-Geometric Contract (SGC) that binds claims and sources to required visuals, budgets, and spatial commitments. Only fully instantiated records become executable assertions; other usable requirements remain soft guidance. Recursive Contract Enforcement (RCE) dynamically triggers checks across stages as evidence emerges. Crucially, during repairs, RCE rechecks affected checkpoint states, preventing repair-induced regressions from propagating silently. We instantiate PosterVisor in HTML/CSS and editable PPTX generators. On the 100-paper Paper2Poster benchmark, PosterVisor-PPT improves observed mean poster-grounded QA accuracy over PosterGen (64.47% vs. 58.53%) and is preferred by human judges in 72.5% of non-tied pairwise comparisons (95% CI, 61.6-83.4%). A secondary 30-paper study also yields higher VLM Overall and PaperQuiz means. These results support rubric-compiled contracts and stage-conditioned enforcement for controllable poster synthesis.
