Translating Research to Slides: Audience-Grounded Presentation Generation via Verifiable Transduction Graphs

Generating a scientific talk from a paper is a constrained translation problem: one shared deck must serve listeners with different knowledge and goals while preserving evidence, required conditions, and claim scope. Prior systems address important components of presentation generation—including source-content organization, audience-conditioned planning, and render-grounded refinement—but generally leave implicit how a shared narrative links source meaning to audience purpose, presentation order, and preservation requirements. We formulate this setting as joint-audience semantic transduction: audience needs may change expression and order, but cannot authorize unsupported claims. AudienceDeck aligns source-anchored semantic units and audience specifications into a frozen contract defining evidence bindings, audience goals, required conditions, and presentation budgets. Each adaptation becomes an executable transduction graph that records source meaning, transformation operation, story role, and conditions that must remain visible. Complete candidates are filtered by fidelity, core coverage, structure, slide, and time budgets; claims exposed before their required conditions are rejected before selection. Among feasible graphs, a prefix-sensitive selector estimates inference risk over visible narrative prefixes and terminal goal attainment after the complete narrative. The selected graph is compiled into traceable page contracts and slide objects, then checked through rendered-output verification and bounded repair. On Academic50, AudienceDeck ranks first among seven evaluated systems in macro coverage (0.7811), correctness (0.9744), and correctness-discounted time efficiency (1.9604), while ranking second in uncorrected time efficiency (2.015). On ArcBench, Judge and Quiz means reach 86.6 and 83.8. The resulting selection record connects source bindings, gate outcomes, selector decisions, rendered audits, and benchmark results in one auditable presentation process.
