An Agentic Retrieval Framework for Autonomous Context-Aware Data Quality Assessment
This paper proposes a unified agentic-retrieval framework that leverages large language models and a multi-agent workflow to autonomously generate context-aware, executable data quality validation logic, incorporating a feasibility-gated execution stage to ensure reliability and adaptability across diverse usage scenarios.

Imagine you have a massive warehouse full of boxes (your data). In the past, checking if these boxes were in good shape was like hiring a single inspector who used the exact same checklist for every single box, no matter what was inside. If the box contained a fragile vase, the inspector checked for cracks. If it contained a hammer, they checked for rust. But if the inspector used the "hammer checklist" on the "vase," they might miss a crack or waste time checking for rust that doesn't matter.
This paper introduces a new, smarter system for checking data quality. Instead of a rigid checklist, it uses a team of AI robots (agents) that act like a highly adaptable quality control team. Here is how it works, broken down into simple steps:
1. The "What Are We Doing?" Conversation
First, you don't just dump the data on the system. You tell it, in plain English, what you plan to do with the data.
- Example: "I'm going to use this data to approve bank loans," or "I'm going to use this data to train a robot to predict the weather."
- The Analogy: Think of this as telling the quality control team, "We are packing these boxes for a delicate art museum," versus "We are packing them for a construction site." The team now knows exactly what kind of damage would be a disaster in each scenario.
2. The Team of Specialized Robots
The system doesn't use one brain; it uses a team of specialized AI agents that pass the work down a line:
- The Interpreter: Listens to your goal and figures out what "good quality" means for that specific goal.
- The Planner: Decides which rules to check. If you are doing loans, it focuses on money and identity. If you are training a robot, it focuses on consistency and patterns.
- The Rule Maker: Writes the actual computer code (the "checklist") to test the data based on the plan.
- The Safety Inspector (The Feasibility Gate): This is the paper's big new idea. Before the rules are actually run, this robot double-checks them. It asks: "Is this rule even possible to run? Does it make sense for this specific data?"
- The Metaphor: Imagine the Rule Maker writes a rule saying, "Check if the temperature is above 100 degrees." The Safety Inspector looks at the data and says, "Wait, this data is about ice cream. The temperature will never be above 100. That rule is useless and might crash the system. Let's fix it."
- The Reporter: Once the rules are run and the data is checked, this robot writes a clear report explaining what was found, strictly based on what the computer actually saw.
3. The "Memory Book" (Retrieval)
To make sure the robots don't make things up (a problem called "hallucination"), the system has a Memory Book.
- Before the Rule Maker writes a new rule, it looks up similar situations in its Memory Book.
- The Analogy: If the team is checking medical data, they don't guess what rules to use. They look at a library of "proven medical checklists" they have used before. They adapt those trusted rules to the new data rather than inventing new ones from scratch. This keeps the rules safe and accurate.
4. The "Do-Over" Loop
If the Safety Inspector rejects a rule (because it's impossible or unrealistic), the Rule Maker doesn't just give up. It gets the feedback, fixes the rule, and tries again. This happens until the rules are perfect and ready to run.
What Did They Prove?
The authors built a working prototype and tested it with a dataset of credit records (like loan applications). They showed three main things:
- Context Matters: When they told the system the data was for "approving loans," it flagged missing money details as a huge problem. When they told it the data was for "training a machine learning model," it ignored the missing money and focused on whether the data was consistent and unique. The same data got two different quality reports based on the goal.
- Safety First: The "Safety Inspector" successfully stopped the system from trying to run impossible rules (like checking for values that don't exist in the data), preventing errors and crashes.
- Trustworthy Results: Because the system separates the "thinking" (AI) from the "doing" (running the code), the final report is 100% based on what actually happened, not on what the AI thought might happen.
In Summary
This paper presents a system that treats data quality not as a one-size-fits-all checklist, but as a customized inspection process. It uses a team of AI agents to understand your goal, a library of past knowledge to stay grounded, and a strict safety gate to ensure the rules it creates are actually possible to run. The result is a data quality check that is smart, safe, and tailored exactly to what you need the data to do.
