The pith

ArcDeck reconstructs a paper's logical flow into slides by first building a discourse tree and commitment document then refining them through coordinated agents.

A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.

The paper introduces a framework that treats turning research papers into presentation slides as a task of rebuilding the original narrative structure rather than simply condensing the text. It begins by extracting a discourse tree and a global commitment document to hold onto the paper's high-level intent and argumentative sequence. These elements then steer a series of specialized agents that repeatedly critique and adjust an outline before the final slides are designed and laid out. The authors also release ArcBench, a set of paired papers and slides, to measure how well the resulting presentations keep their narrative thread intact. If the approach holds, it would reduce the common problem of slides that feel disconnected from the research story they are meant to convey.

Core claim

ArcDeck formulates paper-to-slide generation as structured narrative reconstruction. It parses the input paper to construct a discourse tree and a global commitment document that preserve high-level intent. These priors guide an iterative multi-agent process where agents critique and revise the presentation outline, followed by rendering visual layouts. Evaluation on ArcBench shows that this explicit modeling and coordination significantly enhances narrative flow and logical coherence over direct summarization methods.

What carries the argument

The discourse tree paired with the global commitment document, which act as structural priors that coordinate role-specific agents during iterative outline refinement.

If this is right

  • Slides produced this way retain the sequence of arguments and evidence from the source paper rather than presenting disconnected points.
  • The multi-agent refinement step catches and corrects breaks in logical progression that single-pass summarizers often miss.
  • The same parsing and coordination steps can be reused for other long-document to structured-output tasks that require preserving narrative intent.
  • ArcBench supplies a reusable test set for measuring how well any generation method maintains discourse structure across academic domains.

Where Pith is reading between the lines

These are editorial extensions of the paper, not claims the author makes directly.

  • If the discourse parsing step generalizes, the same pipeline could convert grant proposals or technical reports into executive briefings without manual restructuring.
  • Combining the outline refinement agents with existing layout generators might allow end-to-end creation of complete presentation decks from a manuscript draft.
  • The benchmark could serve as a starting point for studying how narrative quality changes when the same paper is presented to audiences with different levels of domain expertise.

Load-bearing premise

That parsing a discourse tree and global commitment document from raw paper text reliably captures the author's high-level intent without loss or bias.

What would settle it

A side-by-side human evaluation on ArcBench papers where raters score narrative coherence and logical flow of slides made by the framework versus direct text-to-slide baselines, with no statistically significant improvement detected.

read the original abstract

We introduce ArcDeck, a multi-agent framework that formulates paper-to-slide generation as a structured narrative reconstruction task. Unlike existing methods that directly summarize raw text into slides, ArcDeck explicitly models the source paper's logical flow. It first parses the input to construct a discourse tree and establish a global commitment document, ensuring the high-level intent is preserved. These structural priors then guide an iterative multi-agent refinement process, where specialized agents iteratively critique and revise the presentation outline before rendering the final visual layouts and designs. To evaluate our approach, we also introduce ArcBench, a newly curated benchmark of academic paper-slide pairs. Experimental results demonstrate that explicit discourse modeling, combined with role-specific agent coordination, significantly improves the narrative flow and logical coherence of the generated presentations.

Referee Report

2 major / 2 minor

Summary. The paper introduces ArcDeck, a multi-agent framework for paper-to-slide generation that treats the task as narrative reconstruction. It parses the input paper into a discourse tree and global commitment document to preserve high-level intent and logical flow, then uses specialized agents for iterative critique and refinement of the presentation outline before final rendering. The authors also contribute ArcBench, a new benchmark of paper-slide pairs, and claim that explicit discourse modeling plus role-specific agent coordination yields significantly better narrative flow and logical coherence than direct summarization baselines.

Significance. If the central claims hold after addressing the validation gaps, the work would advance automated academic presentation generation by demonstrating the value of explicit discourse structures and multi-agent coordination for coherence. The introduction of ArcBench provides a reusable resource for future benchmarking in this domain, which is a clear positive contribution.

major comments (2)
  1. [Method / Approach] The central claim that discourse modeling and agent coordination improve narrative flow (abstract and method description) rests on the assumption that the initial parsing step reliably extracts a discourse tree and global commitment document without loss, bias, or misrepresentation of cross-section arguments. The manuscript supplies no parser implementation details, accuracy metrics, error analysis, or ablation isolating this step, which is load-bearing because downstream refinement and ArcBench results cannot be attributed to the modeling if the input representation is flawed.
  2. [Experiments / Evaluation] The experimental results section asserts significant improvements in narrative flow and coherence but, consistent with the abstract, provides insufficient detail on baselines, quantitative metrics (e.g., specific scores or statistical tests), ablation studies (with vs. without discourse tree), or inter-annotator agreement on ArcBench. This weakens the ability to evaluate whether the multi-agent refinement is the causal factor.
minor comments (2)
  1. [Abstract] The abstract would be strengthened by including at least one key quantitative result or metric to support the 'significantly improves' claim, rather than leaving all evidence to the full text.
  2. [Method] Notation for the discourse tree and commitment document could be formalized earlier (e.g., with a small example or diagram) to improve readability for readers unfamiliar with discourse parsing.

We thank the referee for the constructive feedback on our work. We address each major comment below and have revised the manuscript to incorporate additional details and analyses where appropriate.

  1. Referee: [Method / Approach] The central claim that discourse modeling and agent coordination improve narrative flow (abstract and method description) rests on the assumption that the initial parsing step reliably extracts a discourse tree and global commitment document without loss, bias, or misrepresentation of cross-section arguments. The manuscript supplies no parser implementation details, accuracy metrics, error analysis, or ablation isolating this step, which is load-bearing because downstream refinement and ArcBench results cannot be attributed to the modeling if the input representation is flawed.

    Authors: We agree that the reliability of the discourse parsing step is foundational to our claims and that the original manuscript provided insufficient implementation details. In the revised version, we have added a new subsection in the Method section that specifies the parser implementation (including the underlying discourse parsing model and any fine-tuning procedures), reports accuracy metrics on a held-out set of academic papers, includes an error analysis of common parsing failures (such as cross-section argument misidentification), and presents an ablation study that isolates the contribution of the discourse tree and global commitment document. These changes allow readers to evaluate the input representation quality and attribute downstream results appropriately. revision: yes

  2. Referee: [Experiments / Evaluation] The experimental results section asserts significant improvements in narrative flow and coherence but, consistent with the abstract, provides insufficient detail on baselines, quantitative metrics (e.g., specific scores or statistical tests), ablation studies (with vs. without discourse tree), or inter-annotator agreement on ArcBench. This weakens the ability to evaluate whether the multi-agent refinement is the causal factor.

    Authors: We acknowledge that the experimental section required more rigorous documentation to support the claims. The revised manuscript now includes expanded descriptions of all baselines with their specific configurations, full reporting of quantitative metric scores accompanied by statistical significance tests, comprehensive ablation studies that isolate the discourse tree and multi-agent refinement components, and inter-annotator agreement statistics for the ArcBench annotations. These additions provide clearer evidence regarding the causal role of the proposed components. revision: yes

Circularity Check

0 steps flagged

No circularity: framework and benchmark are independently introduced without self-referential reductions

full rationale

The paper describes ArcDeck as a novel multi-agent system that parses input papers into a discourse tree and global commitment document to guide slide generation, then evaluates on a newly introduced ArcBench benchmark of paper-slide pairs. No equations, fitted parameters, or derivations are present in the abstract or described process. The central claim rests on experimental results comparing to existing methods, with no load-bearing self-citations, uniqueness theorems, or ansatzes imported from prior author work. The parsing step is presented as an input processing stage rather than a self-defined or fitted output, and the benchmark is explicitly new rather than a renamed or internally validated pattern. This satisfies the criteria for a self-contained contribution with no reduction of claims to their own inputs by construction.
