AI总结:

针对现有聊天机器人多聚焦单用户的问题,本文提出多用户聊天机器人3W设计维度与基于LLM的MUCA框架,含三大模块确定回应内容、时机与对象,还提出MUS加速开发,实验验证其在中小规模目标对话中有效提升参与度等表现。

摘要:

大语言模型(LLMs)的最新进展为聊天机器人开发提供了新途径。然而,现有大多数研究主要聚焦于单用户聊天机器人,这类机器人仅需确定要回答“什么”。本文指出了多用户聊天机器人的复杂性,提出了3W设计维度:说“什么”、“何时”回应以及回答“谁”。此外,我们提出了Multi-User Chat Assistant(MUCA,多用户聊天助手),这是一个专为群组讨论定制的基于LLM的框架。MUCA包含三个主要模块:子主题生成器、对话分析器和对话策略仲裁器,这些模块共同确定合适的回应内容、时机以及恰当的接收对象。本文进一步提出了基于LLM的Multi-User Simulator(MUS,多用户模拟器)以简化MUCA的优化,能够更快地模拟聊天机器人与模拟用户之间的对话,加快MUCA的早期开发。在中小规模参与者的目标导向对话中,案例研究和用户研究表明,MUCA在适时插话、生成相关内容以及提升用户参与度等任务上展现出有效性。

英文摘要:

Recent advancements in large language models (LLMs) have provided a new avenue for chatbot development. Most existing research, however, has primarily centered on single-user chatbots that determine "What" to answer. This paper highlights the complexity of multi-user chatbots, introducing the 3W design dimensions: "What" to say, "When" to respond, and "Who" to answer. Additionally, we proposed Multi-User Chat Assistant (MUCA), an LLM-based framework tailored for group discussions. MUCA consists of three main modules: Sub-topic Generator, Dialog Analyzer, and Conversational Strategies Arbitrator. These modules jointly determine suitable response contents, timings, and appropriate addressees. This paper further proposes an LLM-based Multi-User Simulator (MUS) to ease MUCA's optimization, enabling faster simulation of conversations between the chatbot and simulated users, and speeding up MUCA's early development. In goal-oriented conversations with a small to medium number of participants, MUCA demonstrates effectiveness in tasks like chiming in at appropriate timings, generating relevant content, and improving user engagement, as shown by case studies and user studies.
