Methodology
How TRALEXIA turns an official source into a structured, verified and traceable rule. Each subject explicitly shows its state: verified, partial or no evidence.
Generative AI and decision engine, kept separate
TRALEXIA uses language models to read and structure the regulation and to write readable explanations. The conclusion, however, is determined by a decision engine based on structured rules verified against their source: it is the controlled, traceable layer —not language generation— that sets the position and its level of certainty. The generative layer assists; it does not decide on its own. This does not mean the system is infallible or fully deterministic: coverage depends on the subject and jurisdiction, which is why every answer shows its state —verified, partial or no evidence— rather than feigning a certainty it does not have.
1. Source (SOURCE)
Every rule starts from an identifiable official source — EU regulation, national transposition, resolution or guidance from the competent authority. The reference, jurisdiction and date of the source document are recorded.
2. Structured rule (STRUCTURED RULE)
The source text is translated into a structured, machine-readable rule: explicit conditions, exceptions and scope of application, so that evaluation is controlled and reproducible.
3. Verification (VERIFICATION)
The structured rule is checked against the original source. Until that check is complete, the subject is not presented as verified: it is marked as partial or no evidence.
4. Version (VERSION)
Each rule carries a version and an effective date. When the regulation changes, a new version is created and the history is kept so you can trace which rule applied at any time.
5. Application (APPLICATION)
Given a query or order, the engine selects the applicable rules by subject and jurisdiction and produces a clear position — Yes / No / It depends / Insufficient — with the conditions that support it.
6. Evidence (EVIDENCE)
The result is accompanied by the trace to the applicable regulation: which rule, which version and which source support it. The evidence is traceable and designed for a professional to review.
7. Monitoring (MONITORING)
Sources are monitored to detect regulatory changes. When a relevant update is identified, the affected rule goes through verification again before being considered up to date.
