# Document Intelligence Pipeline – Cognilium AI

On one engagement, scanned financial statements extracted at roughly 12% accuracy with text-only parsing; a multimodal change to the parse stage took the same documents to roughly 94%. Same model, different pipeline — which is the whole argument for building the stages rather than buying a box.


## In short

On one engagement, scanned financial statements extracted at roughly 12% accuracy with text-only parsing; a multimodal change to the parse stage took the same documents to roughly 94%. Same model, different pipeline — which is the whole argument for building the stages rather than buying a box.

Manual data entry from unstructured PDFs

Analysts copy fields out of PDFs into the system of record by hand, one keystroke at a time.

Off-the-shelf OCR misses values in tables, stamped fields and multi-column layouts — exactly where the important numbers live.

A single prompt against a document will produce plausible-looking dates, account IDs and amounts that were never in it. You cannot put that near a system of record.

The same claimant, contract or patient is re-extracted from scratch every time, so cross-document context is lost and duplicate entities pile up.

A vendor updates a form template and extraction quality falls without an error being raised. The damage accumulates downstream for weeks.

**Hybrid parser stack** A router picks the parser per page: native text extraction where the PDF has text, OCR services where it does not, and multimodal handling for pages that are effectively images.

**Fine-tuned classifier** A lightweight classifier trained on your document taxonomy routes each file to the right extraction schema, so a contract is not read with an invoice's expectations.

**Model, regex and schema together** The model pulls fields with high recall; deterministic patterns and typed schemas enforce shape; a second model pass reviews the output as a critic rather than an author.

**Confidence-calibrated validation** Cross-field consistency rules — date ranges, sum checks, lookups against your own records — plus a per-field confidence score, so low-confidence values route to a person.

**Entity resolution and linking** Extracted entities are deduplicated and linked across documents, so the same claimant, matter or patient is recognised rather than recreated.

**Drift gates and an eval harness** Every deployment ships with a labelled eval set and CI gates. When quality drops on a critical field, the pipeline blocks the release instead of shipping it quietly.

**Parse** The router selects the right parser per page rather than per document, because one scanned page in a native PDF is the common case.

**Classify** What kind of document is this? The answer decides which schema and which rules apply downstream.

**Extract** The model pulls fields with high recall; deterministic patterns catch the formats that never vary; layout-aware extraction handles tables.

The model pulls fields with high recall; deterministic patterns catch the formats that never vary; layout-aware extraction handles tables.

**Validate** A second pass reviews the extracted structure. Cross-field rules check sums, date ranges and lookups against your source systems.

A second pass reviews the extracted structure. Cross-field rules check sums, date ranges and lookups against your source systems.

**Score** Each field gets a calibrated confidence. Below threshold it goes to a person; above it, it proceeds. That threshold is a dial you own.

**Graph** Entities — people, organisations, accounts, claims, contracts — are deduplicated and stored as nodes with their embeddings alongside.

**Link** New documents are linked into the existing graph, so an amendment finds its contract and a follow-up finds its original.

**Output** The final payload is shaped to your downstream contract, so the system of record receives what it expects rather than what we produced.

**Medical record abstraction** Discharge summaries, operative notes and lab reports parsed into standard clinical resources, with de-identification running at the parse stage before anything leaves your environment.

**First-notice-of-loss automation** Loss packets — reports, repair estimates, photos, standard forms — extracted into structured claim records and pushed into the claims system.

**Contract abstraction at portfolio scale** Agreements abstracted to a structured schema and linked to the matter in your document system, with amendments and exhibits resolved to their parents.

**Investment document parsing** Statements, subscription documents and capital-call notices parsed into an accounting system, with entity resolution linking each one to the right holding.

**Form intake and case files** Citizen submissions, request packets and case files routed to the right downstream system with confidence-scored fields, deployable on-premises.

**Discovery and schema design** We sample 50 to 100 of your real documents, design a typed schema per document type, and define the eval set with you.

**Prototype** A working end-to-end pipeline on your sample corpus, with an evaluation harness your team can use to grade every field itself.

**Production deployment** The pipeline deployed into your own environment, integrated with your systems of record, with drift gates and evaluation running in CI.

**Hand-off and monitoring** Runbooks, coverage and regular drift reports. Your team owns the schemas; we own pipeline reliability until you choose to take it in-house.

Documents read, classified, extracted and validated, with confidence you can audit.

Eight stages from a PDF nobody can query to structured data your system of record will accept — and a per-field confidence score deciding what a person still needs to look at.

cross-field validation rules, plus 16 across documents

stages, each replaceable without rewriting the rest


## Five failure modes, and a stage against each

Every stage of the pipeline below exists to catch one of these before it reaches your system of record.


## The eight-stage pipeline

Each stage is a named component with its own evaluation set. You can swap any one of them without rewriting the rest.


## Confidence comes from evidence, not self-assessment

Every extracted value carries its source quote and page. A value without a traceable source is not an answer; it is a guess.

The buyer's real question is what happens when it is wrong, and the answer is that it says so: per-field confidence, alternatives queued for a person, and nothing silently written to the system of record.


## Six capabilities, wired into one pipeline

No black box. Every component is named, swappable, and runs in your own environment.


## The same pipeline, configured per domain

Schemas, integrations and compliance posture change. The architecture does not.


## Every milestone has something you can grade

The evaluation harness is a deliverable, not an internal tool: your team grades the output rather than taking our word for it.

Send 50 to 100 of your real files. We run a benchmark on your own corpus, hand you the report, and tell you plainly which fields are reliable enough to automate and which ones will still need a person.
