Data Characteristics of This Use Case
The sources of these research reports mainly include public reports released by defense industry research institutes, internal technical documents from defense-focused organizations, and specialized analysis from defense information aggregation platforms. Update cycles fall into two categories: regular quarterly/annual reports and ad-hoc analyses for emergency events. Document formats are mostly multi-chapter PDF files, with some Excel attachments containing nested parameter tables. Core document fields include equipment model, in-service quantity, unit cost, delivery cycle, and more. Specialized units include exclusive identifiers such as sets, units, rounds, and ten thousand yuan per unit. Individual long documents can range from hundreds to thousands of pages in length.
Constraints for Document Parsing and Chunking
The fact that individual documents can range from hundreds to thousands of pages increases parsing timeout risk. Adjust parsing timeout parameters to accommodate this. The presence of specialized fields and exclusive units requires retaining key parameter contexts during parsing, and chunking must preserve full field associations. Some data sources come from internal platforms such as intranet Confluence, so adapt intranet access permissions and content extraction logic to avoid failed intranet document parsing. Multi-chapter nested document structures require retaining hierarchical relationships during chunking, to avoid information logic breaks from flat splitting.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 1000–2000 MB | Accommodates the file size of single defense research report PDFs with hundreds of pages, to avoid upload truncation |
PARSE_FILE_TIMEOUT_SECONDS | 600–900 seconds | Longer processing time is required for long PDF parsing, to avoid mid-process timeout interruptions |
Chunk size | 800–1200 characters | Balances the integrity of specialized fields and retrieval granularity, to avoid splitting core parameter paragraphs |
Parent-child Chunking Switch | Enabled | Retains the hierarchical relationship between model chapters and technical parameter subsections in research reports, to avoid context breaks |
INTRANET_PARSE_ENABLE | Enabled | Adapts to parsing requirements for internal data sources such as intranet Confluence, to extract content from intranet documents |
FIELD_RECOGNITION_RULE | Match against defense specialized field library | Accurately identifies exclusive fields such as in-service quantity and unit cost, to avoid misjudgment of units |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require targeted analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Symptom: Hierarchical information is still lost after enabling the parent-child chunking switch. Cause: The nested level threshold for parent-child chunking was not configured correctly, causing deep subsections to be split flatly.
- Symptom: Content cannot be extracted from intranet Confluence pages. Cause: Intranet data source parsing permissions were not enabled, or proxy and authentication parameters for intranet access were not configured.
- Symptom: Invalid command prompt is returned after uploading an Excel document containing defense equipment data. Cause: The table structured parsing switch was not enabled, causing native table content to be split as plain text, failing to recognize specialized data associated with rows and columns.
How to Verify Proper Configuration
- Upload a single defense research report PDF with more than 500 pages, check whether the parsing task completes within the configured timeout threshold without abnormal errors.
- Upload a test document to an intranet-deployed Confluence page, confirm that complete research report content can be extracted after parsing, with no empty fields or missing content.
- After enabling the parent-child chunking switch, check whether the chunk list retains the chapter hierarchy of the research report, such that subsections under "Technical Parameters of a Certain Model Equipment" are not processed flatly.
- Upload an Excel table containing specialized fields, confirm that structured fields such as in-service quantity and unit cost can be extracted after parsing, with no invalid command prompts.
