Sovereign AI for regulated European environments

Control over a classification model is one part of a document-processing architecture. We propose a review of OCR, hosting, data transfers, access controls and integration dependencies alongside model evaluation. The target design must address the complete workflow and the people responsible for operating it.

DNA Solutions by the numbers

We build and maintain AI, data and billing infrastructure for European enterprises with regulated workloads and high-volume transaction systems.

A senior team of engineers and consultants across Europe.

What the pipeline includes

We build the pipeline inside your cloud and your jurisdiction. Each capability below is measured on a sample of your own documents before any wider rollout.

High-volume invoice parsing

The pipeline parses invoices and structured documents at volume, extracting line items, totals and reference fields automatically into your downstream systems. We build it on OCR with Tesseract and tune feature extraction to the recurring formats your operations generate most.

Custom classification models

Select and evaluate a classifier for the document categories in the workflow. Use representative labeled examples, hold-out tests and error analysis to compare approaches. Define acceptance criteria before deployment. Model ownership does not by itself establish control of OCR, infrastructure, integrations or the complete document-processing pipeline.

Automated metadata extraction

The pipeline extracts dates, parties, amounts and document types from unstructured files. This metadata feeds search, indexing and audit trails at the precision controlled workflows require. Every field remains traceable to its source page, giving downstream teams reliable data and auditors a complete lineage.

Human-in-the-loop validation

For the document classes where an error carries cost, the pipeline routes low-confidence predictions to a human reviewer before the result moves downstream. We set the confidence threshold per document type, so the bulk of clean documents flow through automatically while edge cases land in a review queue.

Secure AI systems delivered by DNA Solutions

Custom AI built for European enterprises and deployed inside private clouds, with no OpenAI or hyperscaler dependency. The three workloads below cover document classification, per-type extraction and structured metadata, each model sized to the precision the workflow requires.

Questions about data control and AI compliance

What clients ask about accuracy, hyperscaler independence and AI Act compliance.

What document types can DNA Solutions classify and extract?

DNA Solutions builds pipelines for invoices, contracts and scanned records, and for the mixed document flows enterprise operations generate day to day. Our team trains a classification model per document type, then extract the structured fields each type carries: dates, parties, amounts, totals and reference numbers, into your downstream systems. The pipeline is sized to the document classes your workflow processes most, so accuracy holds on the formats that matter. When a new document type appears, we add a class and retrain on the existing pipeline. Every extracted field traces back to its source document, which is what lets the output stand up under audit.

How accurate is the classification?

DNA Solutions develops custom document classifiers and evaluates them on representative data. In the published Canon benchmark, the classifier scored higher than Azure AI Document Intelligence on two of three tested datasets and tied on the third. The 94.7% versus 84.2% comparison refers to one dataset. Hosting, OCR, integration and compliance require separate evaluation.

What technology stack does DNA Solutions use?

The pipeline combines OCR with Tesseract for text recognition, word2vec and tf-idf for feature extraction, and an SVM classifier tuned per document type. We select established components that fit the document set, which keeps the pipeline explainable: we can trace why a given document was classified the way it was. That matters when an auditor or a domain expert questions a decision. We run the stack on your own cloud account or on-premise environment, with no proprietary license locking you in, and every stage feeds search, indexing and audit trails. When the document mix shifts, we retrain or adjust the affected stage on the existing pipeline.

Can the pipeline handle high invoice volumes?

Yes. The parsing pipeline is built to process invoices and structured documents at volume, extracting line items, totals and reference fields automatically into downstream systems. We tune the feature extraction to the recurring formats your operations generate, so throughput stays consistent as volume grows and the extracted fields remain traceable back to the source document for audit. We size the pipeline to your production volumes and validate it on a sample of your own invoices before any wider rollout, so the throughput you see in production matches what we measured. Where a value carries cost, low-confidence extractions route to human review before they move downstream, and those corrections feed back into the model. The pipeline absorbs your invoice volume without manual re-keying, while keeping the audit trail intact.
