Contract data extraction turns unstructured agreement text into structured fields such as parties, dates, fees, clauses, obligations, and renewal windows.

Contract data extraction is the AI technique of pulling structured data — parties, dates, amounts, clauses, obligations — out of a contract and into queryable fields. It is the front door of contract intelligence: without extraction, the rest of the stack has nothing to work with.

Foundation

Contract data extraction sits between the source PDF and every downstream answer. Modern systems extract 50+ standard fields with high accuracy. Custom fields via playbook or fine-tuning extend the model to organization-specific data shapes.

TL;DR

Contract data extraction = pulling structured fields (parties, dates, amounts, clauses) from contracts.
Broader than clause extraction: covers entities and metadata in addition to clauses.
Output is queryable structured data, not a search index over PDFs.
Vallor extracts every standard field from every contract in your portfolio as the first step of its intelligence layer.

The contract data extraction pipeline

Ingest the source document

PDF, DOCX, email body, or e-signature platform export. Format-agnostic ingestion is table stakes.

OCR and layout parsing

Scanned PDFs go through OCR; layout-aware parsing preserves clause, section, and table structure.

Entity extraction

Parties, dates, amounts, jurisdictions, governing law. The metadata that anchors every downstream query.

Clause identification and classification

Identify clause boundaries and label by type (liability, indemnity, termination, IP, audit, etc.).

Field-level extraction inside each clause

Liability cap amount, indemnity scope, termination notice window, audit frequency. The granular details that drive comparison-to-playbook.

Validate and route low-confidence extractions

Edge cases (bespoke language, ambiguous structure) flagged for human review. Mature systems learn from the corrections.

Output: queryable structured data with citations

Every field is queryable; every answer traces back to the source clause and contract.

How Vallor handles contract data extraction

Extract from every source you already haveExisting CLM, shared drives, email, ERP attachments. No migration required.

Structure entities, clauses, and obligations togetherParties, dates, amounts, governing terms, clauses, and obligations all extracted into one queryable layer.

Maintain source-anchored citationsEvery extracted field points back to the source location in the contract. Audit-ready.

Where teams trip up

✗

Treating extraction as searchSearch returns text that contains a keyword. Extraction returns structured data. The two are fundamentally different — search cannot answer 'which contracts cap liability above 2x?'.

✗

Trusting pre-trained models on custom dataOff-the-shelf models handle common contract fields well. Organization-specific fields (custom audit rights, unusual price escalators) need playbook-driven extraction or fine-tuning.

✗

Not preserving source citationsAn extracted field without a source pointer cannot be audited or trusted. Enterprise legal teams cannot operate on uncitable extraction.

✗

Extracting once and not maintainingContracts are amended. Side letters get added. Extraction must keep up with contract evolution, not just initial signing.

FAQ

What is the difference between contract data extraction and document AI?

Document AI is the broader category — extraction, classification, summarization across any document type. Contract data extraction is the application of document AI to contracts specifically, with contract-aware models, fields, and playbooks.

How many fields can be extracted from a typical contract?

Modern systems extract 30-70 standard fields per contract (parties, dates, amounts, clauses, terms) plus any organization-specific fields defined in the playbook. Total extracted data points per contract can be 100+.

What is the accuracy of contract data extraction?

On standard fields in well-formatted contracts, accuracy is typically 90%+. On bespoke language or poorly-scanned PDFs, accuracy drops. Mature systems route low-confidence extractions to human review.

Can extraction work on contracts in languages other than English?

Yes, with multilingual models. Quality depends on the language coverage and on whether the playbook has been calibrated for that language.

How does Vallor handle contract data extraction?

Vallor extracts entities, clauses, and obligations from every contract in your portfolio with source-anchored citations. The team can query in plain English and trust that every answer traces back to a specific clause in a specific contract.
