DialogStudio: Towards Richest and Most Diverse Unified Dataset Collection for Conversational AI

Abstract: Despite advancements in conversational AI, LLMs encounter challenges to handle diverse conversational tasks, and existing dialogue dataset collections often lack diversity and comprehensiveness. To tackle these issues, we introduce DialogStudio: the largest and most diverse collection of dialogue datasets, unified under a consistent format while preserving their original information. Our collection encompasses data from open-domain dialogues, task-oriented dialogues, natural language understanding, conversational recommendation, dialogue summarization, and knowledge-grounded dialogues, making it an incredibly rich and diverse resource for dialogue research and model training. To further enhance the utility of DialogStudio, we identify the licenses for each dataset, design external knowledge and domain-aware prompts for selected dialogues to facilitate instruction-aware fine-tuning. Furthermore, we develop conversational AI models using the dataset collection, and our experiments in both zero-shot and few-shot learning scenarios demonstrate the superiority of DialogStudio. To improve transparency and support dataset and task-based research, as well as LLM pre-training, all datasets, licenses, codes, and models associated with DialogStudio are made publicly accessible\footnote{\url{https://github.com/salesforce/DialogStudio}}.

• The paper introduces DialogStudio, aggregating 80+ diverse dialogue datasets into a unified format for versatile conversational AI research.
• It standardizes dataset formatting, facilitating easier training and robust evaluation of language models across various dialogue tasks.
• Empirical results demonstrate superior zero-shot and few-shot performance, validating the benefits of integrated external knowledge and instruction tuning.
