Abstract: Task-oriented dialogue (TOD) systems support users in achieving domain-specific goals via natural language interactions and critically depend on high-quality datasets. However, existing datasets often lack authenticity, fine-grained semantic annotations, and explicit process control, limiting effectiveness in complex business scenarios. To address these, we introduce CRSA, a Chinese TOD dataset that integrates diverse sources to construct semantically rich, structurally realistic dialogues, and adopts a multi-level annotation framework to model dialogue acts, user intents, and task flows more effectively. To evaluate the quality and application potential of CRSA, we conduct three sets of experiments spanning data quality, system training effectiveness, and task adaptability. Results demonstrate that CRSA provides strong support for process modeling, strategy learning, and response generation, establishing it as a robust and versatile resource for TOD research.
