Engineering guide
For scanned PDF ingestion for a knowledge base, map costs to work packages, deliverables and external inputs as shown below. This defines scope rather than a lump-sum price, fixed schedule, payment terms or default charging rules.
An OCR workflow quotation should establish the material, downstream users and error-handling process before separating engineering from ongoing operating costs. Count files, pages, scanned pages and layout types separately; a file count does not describe the entire workload.
Counting samples for a quotation
This is an illustrative count, not customer data: 10 PDF files contain 250 pages, including 30 scanned pages requiring recognition. The document inventory counts 10 files, page processing counts 250 pages, and candidate OCR input counts 30 pages. Image text, complex tables or pages requiring field extraction need separate task definitions. Processing only 30 pages does not necessarily complete the document workflow.
Include clear pages, poor-quality pages, tables, content spanning pages and unreadable pages in the sample, with agreed disclosure boundaries. Confirm ground truth, field rules and the review method together with the sample.
Separating engineering and ongoing costs
Swipe the table horizontally to view all columns.
| Work package | Engineering output to agree | Workload or expense to list separately |
|---|---|---|
| Inventory and scope | Format inventory, layout groups, samples and acceptance definitions | Data preparation, ground truth and material rights |
| Parsing and OCR integration | Page extraction, recognition API, failure records and retry flow | Unusual formats, model-service calls or runtime resources |
| Recognition postprocessing | Field mapping, table organization and source-page references | New layouts, changed field rules and human review |
| Business integration | Upload, task status, exports and authorization APIs | Existing-system changes, accounts and storage integration |
| Deployment and maintenance | Configuration, operating instructions, logs and agreed test records | Servers, licenses, hosting and later model updates |
Confirm fees against actual samples and agreed outputs. This table specifies no lump-sum price and does not assume that continuing human review is included in a one-time development fee.
Establishing workflow completion
Check page parsing, detection and retry of failures, and navigation from outputs back to the source page. Then compare text or fields against the frozen sample. Character recognition, field extraction, table structure and business usability need separate metrics and acceptance conditions. A demonstration page without ground truth cannot establish overall accuracy.
The Chinese-language local knowledge-base project report includes multiple-format parsing, local OCR and source navigation. It does not establish recognition accuracy for arbitrary new material. Submit anonymized samples, page counts, output fields, review responsibilities and deployment conditions through the Chinese-language knowledge-base development service to assess one representative workflow before pricing expansion.
Work packages and deliverables
Swipe the table horizontally to view all columns.
| Work package | Deliverables to agree | External inputs and scope |
|---|---|---|
| OCR integration | Page extraction, recognition interface, failure records and retry cases | List OCR licensing, runtime resources and document permissions separately |
| Samples and correction | Layout inventory, reference annotations and error-handling rules | Assign responsibility for sample preparation and ongoing human correction |
| Indexing and references | Chunking, source fields, update/delete handling and retrieval tests | Itemize models, storage, incremental processing and maintenance scope |
What inputs are needed before starting?
De-identified scans, sample OCR output, fixed test questions, a permissions matrix and deployment conditions. Check document versions and availability first and retain missing items as unresolved inputs.
How should delivery and acceptance be defined?
Use fixed file versions to test normal, failed and cross-page content, updates, deletions and denied access; retain the reference path. Passing ingestion and source-reference checks does not establish answer accuracy; test retrieval, access control and generated answers separately.
Enterprises in Beijing, China, can submit these inputs for remote review. Agree prototype integration, sample shipment, site work and associated costs for the specific project.
