The Challenge
Beyond Public Document Benchmarks
DocVQA, FUNSD, and RVL-CDIP advanced document understanding research. But production IDP must handle your specific document types, layouts, and extraction targets, not academic benchmarks.
Real-world document processing handles scanned forms, mixed-layout PDFs, handwritten fields, and document types that benchmark datasets never include. IDP models trained on public data underperform when deployed on proprietary document workflows.
Off-the-shelf document datasets suffer from layout diversity gaps (limited template variation per document class) and scan quality mismatch between clean benchmark PDFs and low-quality operational scans.
LXT builds custom document datasets from your actual document types. We annotate layout regions, key-value pairs, tables, and extraction targets across the document variation your IDP system will encounter in production.
Why Teams Upgrade
Limitations of Public Document AI Datasets
Standard benchmarks serve research well. Production deployments need more.
| Dataset | Primary Limitation | Impact |
|---|---|---|
| FUNSD | 49 scanned forms only; simple layout types; English only; insufficient scale and variety for production form understanding models | Limited scale |
| DocVQA | Single-page documents only; VQA framing mismatches most IDP use cases; limited document type diversity | VQA framing |
| RVL-CDIP | Image classification only; no OCR, layout, or extraction annotations; 16 broad document categories | Class only |
| DocLayNet | 6 document categories from public sources; limited enterprise document types; no handwritten or form content | Public bias |
| CORD | Restaurant receipts only; narrow document type; insufficient for multi-document IDP pipeline training | Single-type |

Need a custom configuration?
We've built datasets across dozens of domains and use cases. Let's scope yours.
Capturing Complexity
Edge Cases in Document Processing
High-accuracy models handle rare attributes that public datasets miss.
Mixed Handprint and Printed Text
Many operational forms contain both printed labels and handwritten responses. Models must handle the boundary between machine-printed and handwritten text reliably.
Tabular and Nested Structures
Complex tables with merged cells, nested headers, and spanning rows challenge both OCR and structure recognition models. Expert table annotation captures these relationships.
Degraded Scan Quality
Operational document scans include skew, low contrast, coffee stains, and physical damage. Realistic scan degradation distribution in training data prevents quality-induced failures.
Multi-Page and Multi-Document Flows
IDP pipelines process multi-page documents and document packets. Page boundary detection and document type segmentation annotations support end-to-end pipeline training.
Ground Truth Quality
Human-in-the-Loop Annotation
Precise annotation bridges raw data and learnable signal. Expert annotators deliver precision automated tools can't match.
Layout Annotation
Trained annotators mark page regions with bounding boxes and semantic labels using your target schema. Pixel-accurate annotations for segmentation model training.
Key-Value Extraction Labels
Field name and field value bounding boxes annotated with field type taxonomy. Supports template-free and template-based IDP model architectures.
Table Structure Annotation
Row, column, and cell-level annotations including spanning cells, header rows, and multi-level column headers for complex tabular document understanding.

Frequently Asked Questions
Document Dataset FAQs
Can you use our existing document templates?+
Yes. We work with your document templates to build training corpora that match your production document variation. We analyze existing documents to characterize layout and quality distribution before proposing collection volume.
Do you support handwritten field annotation?+
Yes. We annotate both printed and handwritten fields, with separate confidence flags for handwritten content. Annotators with handwriting recognition expertise handle difficult handwritten value fields.
What formats do you deliver?+
COCO JSON, FUNSD JSON, DocLayNet JSON, and custom formats. Bounding box coordinates in both pixel and normalized formats. Table annotations in structured JSON with cell relationship graphs.
Can you handle multilingual and right-to-left documents?+
Yes. We annotate documents in 40+ languages including Arabic, Hebrew, and other RTL scripts. Annotators are native speakers of target languages with document processing domain training.
How do you handle sensitive document content?+
All sensitive documents are processed under strict access controls. PII fields are flagged in annotations and can be redacted or pseudonymized in delivery based on your data agreement requirements.
What does a custom document dataset cost?+
Projects range from $12K for focused single-document-type datasets (1,000-5,000 pages) to $100K+ for large multi-type, multi-language corpora with complex table and form annotation.
How quickly can you deliver?+
Focused document datasets typically deliver in 3-6 weeks. Multi-type collections with quality reviews run 6-12 weeks depending on annotation complexity and volume.
