Self-Service or Not? How to Guide Practitioners in Classifying AI Systems Under the EU AI Act
This study addresses the gap in empirical research on EU AI Act compliance by evaluating a self-service decision-support tool with 78 practitioners, revealing that while legal interpretation remains challenging, targeted guidance significantly improves the accuracy of AI system risk classification.

Imagine the European Union just handed down a massive, complex rulebook for Artificial Intelligence called the EU AI Act. Think of this rulebook like a strict traffic code for self-driving cars. Just as a car can be a harmless toy, a daily commuter vehicle, or a dangerous racing machine, AI systems vary wildly in how risky they are.
The law says: "The more dangerous the AI, the stricter the rules it must follow."
But here's the problem: The rulebook is written in "Legalese"—a language full of confusing jargon, cross-references, and vague definitions. For a regular engineer or business owner trying to figure out if their AI is a "toy" (low risk) or a "racing machine" (high risk), it's like trying to navigate a maze blindfolded while holding a dictionary written in a dead language.
This paper is about a team of researchers who built a digital "GPS" (a web-based tool) to help people navigate this maze. They wanted to see: Can regular people use this GPS to find their way, or do they need a professional tour guide?
The Experiment: Two Ways to Test the GPS
The researchers didn't just build the tool; they tested it with 78 real-world practitioners (engineers, product managers, and tech experts) from a giant global company. They did this in two phases:
- The "Co-Pilot" Phase (Beta): Imagine sitting in a car with a driving instructor. The researchers watched 11 people use the tool, took notes on where they got stuck, and answered their questions in real-time.
- The "Solo Drive" Phase (Final): Imagine giving the car keys to 67 people and letting them drive alone. The researchers didn't watch; they just looked at the data logs (how long they stared at a question, how many times they clicked "Help") and asked them how they felt afterward.
What They Discovered: The Roadblocks
The researchers found that while the GPS was helpful, the road was full of potholes. Here are the main bumps they hit, explained with simple analogies:
1. The "What is a Car?" Confusion
The law defines what an "AI system" is, but the definition is fuzzy.
- The Analogy: Imagine the law says, "A vehicle is anything with wheels." Is a skateboard a vehicle? Is a shopping cart? Is a toy car?
- The Problem: Practitioners struggled to decide if their specific AI actually counted as an "AI" under the law.
- The Fix: The tool needed to provide clear examples (like showing a picture of a skateboard vs. a car) to help users understand the definition.
2. The "Safety Helmet" Mystery
To be classified as "High Risk," an AI often needs to be a "safety component."
- The Analogy: The law says, "If you wear a safety helmet, you are in the High Risk zone." But the law's definition of a "safety helmet" is different from the definition used by the construction industry or the medical industry.
- The Problem: A user might think, "My AI is a safety feature!" but the law says, "No, under this specific regulation, it doesn't count." This caused massive confusion.
- The Fix: The tool needed to explain which specific rulebook applied to the user's situation, not just quote the law.
3. The "Cross-Reference" Trap
The AI Act points to 20 other European laws (like laws about medical devices or machinery).
- The Analogy: To pass the test, you have to know the rules of the "Medical Game," the "Construction Game," and the "Transport Game" all at once.
- The Problem: Most engineers know their tech, but they don't know the specific legal rules of 20 different industries. They didn't know if their AI needed a "third-party inspection" (like a car needing a safety inspection).
- The Fix: The tool had to act as a translator, summarizing these complex laws into plain English.
4. The "Expert" Lifeline
The most surprising finding was about human help.
- The Analogy: Even with the best GPS, sometimes you hit a roadblock where the map is blank. You need to call a local who knows the terrain.
- The Data: In the "Solo Drive" phase, very few people clicked the button to "Contact an Expert." They thought they could figure it out alone. However, when asked later, they admitted that having an expert available was the most valuable thing they could have had.
- The Lesson: People are overconfident. They don't ask for help until they are stuck, but having the option to ask a pro gives them the confidence to drive.
The Verdict: Self-Service or Not?
The title asks, "Self-Service or Not?" The answer is a "Yes, but..."
- Yes: You can use a self-service tool to classify your AI.
- But: You cannot just give them the raw law. You must wrap the law in context, examples, and clear explanations.
If you just hand a user a 1,000-page legal document, they will get lost. But if you give them a smart assistant that says, "Here is the rule, here is what it means for your specific project, and here is an example of a similar project that passed," then they can do it.
The Takeaway for the Real World
The researchers concluded that for the EU AI Act to work, regulators and tool-makers need to stop thinking like lawyers and start thinking like user experience designers.
- Don't just quote the law: Explain it.
- Don't assume expertise: Provide examples for every confusing term.
- Offer a safety net: Make it easy to talk to a human expert when the "GPS" signal gets weak.
In short, the AI Act is a complex mountain. Practitioners can climb it, but they need a good map, a guidebook with pictures, and a radio to call for help when the path gets steep. This paper proved that with the right tools, regular people can successfully navigate the climb.
