PPTAgent: Generating and Evaluating Presentations Beyond Text-to-Slides

ACL ARR 2025 February Submission1123 Authors

Abstract:

Automatically generating presentations from documents is a challenging task that
requires accommodating content quality, visual appeal, and structural coherence.
Existing methods primarily focus on improving and evaluating the content
quality in isolation, overlooking visual appeal and structural coherence,
which limits their practical applicability. To address these limitations, we
propose PPTAgent, which comprehensively improves presentation generation through
a two-stage, edit-based approach inspired by human workflows.
PPTAgent first analyzes reference presentations to extract slide-level functional
types and content schemas, then drafts an outline and iteratively generates
editing actions based on selected reference slides to create new slides.
To comprehensively evaluate the quality of generated presentations, we
further introduce PPTEval, an evaluation framework that assesses presentations
across three dimensions: Content, Design, and
Coherence. Results demonstrate that PPTAgent significantly
outperforms existing automatic presentation generation methods across all
three dimensions.
