- Abstract: Argument generation is a challenging task in natural language processing,
which requires rigorous reasoning and proper content organization. Inspired by
recent chain-of-thought prompting that breaks down a complex task into
intermediate steps, we propose Americano, a novel framework with agent
interaction for argument generation. Our approach decomposes the generation
process into sequential actions grounded on argumentation theory, which first
executes actions sequentially to generate argumentative discourse components,
and then produces a final argument conditioned on the components. To further
mimic the human writing process and improve the left-to-right generation
paradigm of current autoregressive language models, we introduce an argument
refinement module which automatically evaluates and refines argument drafts
based on feedback received. We evaluate our framework on the task of
counterargument generation using a subset of Reddit/CMV dataset. The results
show that our method outperforms both end-to-end and chain-of-thought prompting
methods and can generate more coherent and persuasive arguments with diverse
and rich contents.

- Unlocking Varied Perspectives: A Persona-Based Multi-Agent Framework with Debate-Driven Text Planning for Argument Generation [25.43678472601801]
We propose a persona-based multi-agent framework for argument writing.
Inspired by the human debate, we first assign each agent a persona representing its high-level beliefs from a unique perspective.
We then design an agent interaction process so that the agents can collaboratively debate and discuss the idea to form an overall plan for argument writing.

Mixed-initiative dialogue tasks involve repeated exchanges of information and conversational control.
Agents gain control by generating responses that follow particular dialogue intents or strategies, prescribed by a policy planner.
Standard approach has been fine-tuning pre-trained language models to perform generation conditioned on these intents.
We instead prompt large language models as a drop-in replacement to fine-tuning on conditional generation.
