VISAR: A Human-AI Argumentative Writing Assistant with Visual Programming and Rapid Draft Prototyping
This addresses the challenge of improving argumentative writing for writers by providing better control and sensemaking, though it is incremental as it builds on existing LLM capabilities.
The paper tackles the problem of argumentative writing by introducing VISAR, an AI-assisted system that helps writers brainstorm hierarchical goals, organize argument structures, and enhance persuasiveness, with a lab study confirming its usability and effectiveness.
In argumentative writing, writers must brainstorm hierarchical writing goals, ensure the persuasiveness of their arguments, and revise and organize their plans through drafting. Recent advances in large language models (LLMs) have made interactive text generation through a chat interface (e.g., ChatGPT) possible. However, this approach often neglects implicit writing context and user intent, lacks support for user control and autonomy, and provides limited assistance for sensemaking and revising writing plans. To address these challenges, we introduce VISAR, an AI-enabled writing assistant system designed to help writers brainstorm and revise hierarchical goals within their writing context, organize argument structures through synchronized text editing and visual programming, and enhance persuasiveness with argumentation spark recommendations. VISAR allows users to explore, experiment with, and validate their writing plans using automatic draft prototyping. A controlled lab study confirmed the usability and effectiveness of VISAR in facilitating the argumentative writing planning process.
