What the data for this category looks like
Data for professional chain intelligent due diligence reports primarily comes from store operation weekly reports, supply chain reconciliation ledgers, franchise cooperation agreements, and regional compliance self-inspection documents. The core data update cycle is monthly. Franchise-related documents are updated in real time when cooperation is renewed or changed. All documents follow a fixed structure with four modules: basic store information, revenue details, cost composition, and compliance qualifications. Fields include average daily customer traffic per store (unit: person-times), per-square-meter efficiency (unit: yuan/square meter), monthly revenue per store, supplier settlement cycle, and others. Some documents include attachment links to real store photos.
What constraints these characteristics impose on document parsing and chunking
The fixed module structure of professional chain due diligence reports requires content to be split along preset chapter boundaries during parsing, preventing mixing of revenue, compliance, and other information across chapters. Real-time updated franchise cooperation documents require incremental parsing logic, so only updated content fragments are processed. Parsing components must recognize and retain attachment links for real store photos, to preserve associated relationships. For field content with clear units, chunking must retain the binding between units and indicators, avoiding confusion between similar business indicators during subsequent retrieval. Long-form regional summary reports require limiting individual chunk length, to fit model context windows.
How to set configurations
| Configuration Item | Recommended Value Range | Rationale |
|---|---|---|
PARSE_CHUNK_SIZE | 800–1200 characters | Fits the chapter content length of professional chain due diligence reports, prevents single chunks from containing excessive cross-module information |
PARSE_CHUNK_OVERLAP | 150–200 characters | Retains chapter titles and indicator associations between adjacent chunks, improves context integrity during retrieval |
PARSE_ENABLE_INCREMENTAL | Enabled | Adapts to real-time update requirements for franchise documents, reduces overhead from repeated full-file parsing |
PARSE_ATTACHMENT_LINK_PARSE | Enabled | Recognizes and retains attachment links for store photos in documents, prevents loss of supplementary information |
PARSE_FIELD_UNIT_BIND | Enabled | Binds indicators to their corresponding units, avoids confusion between similar business indicators during retrieval |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Adapts to parsing time for long-form regional summary reports, prevents timeout interruptions |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Phenomenon: RAG retrieval results only return body fragments, and do not include document chapter titles. Cause: Chapter title binding configuration is not enabled, and chapter metadata is stripped during chunking.
- Phenomenon: When deploying a model using Vllm 0.10 version, parsed business fields cannot be extracted by subsequent nodes. Cause: Vllm 0.10 has compatibility limitations with structured field output formats. Parsing prompts must be adjusted or the version must be adapted.
- Phenomenon: After uploading a document in the server environment, the parsing node returns a 404 error. Cause: The server has not configured access permissions for the file upload path, or the parsing node cannot access the mapped storage directory.
How to confirm configurations are set correctly
- A test document including chapter titles and unit fields may be uploaded. Parsed chunk content is checked to confirm chapter titles and indicator units are included in the chunk content.
- A franchise document marked as updated may be uploaded. The processing scope of the parsing task is checked to confirm only updated content is parsed.
- A parsing task for a long-form regional summary report may be triggered. The task is confirmed to not be interrupted due to timeout.
- A document including attachment links may be uploaded. Associated information in the parsing results is checked to confirm links are correctly recognized and retained.
