What Data for This Category Looks Like
Financial report data related to ordnance and equipment mainly comes from annual reports, semi-annual reports, and quarterly reports of listed companies disclosed by public stock exchanges, as well as industry statistical briefs released by national defense industry regulatory authorities. Disclosure schedules follow these rules: annual reports are released before April each year, semi-annual reports before August each year, and quarterly reports within one month after the end of each quarter. Most documents are in PDF format. They contain standardized financial statements and management discussion and analysis sections. Sections covering equipment business split and list core product model revenue, capacity utilization rate, order delivery volume and other fields. Common units include ten thousand RMB, units/set, kilometers, and similar measures.
Constraints for Document Parsing and Chunking
Document format differences across multiple sources require the parsing module to adapt to two formats: standardized financial reports and self-made industry briefs. This prevents missing key equipment business data. The high-frequency disclosure schedule creates demand for batch parsing. The module must support parallel processing of multiple files. Equipment business fields are strongly tied to model numbers. Chunking must retain contextual associations. Do not split cross-paragraph model, revenue, and capacity information. Diverse unit types require the parsing module to accurately identify and associate units with corresponding fields. This prevents unit confusion in subsequent analysis.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | Single PDF of ordnance and equipment financial reports is usually 50-100 pages. Standard parsing time ranges from 60-90 seconds. Reserve redundant time to avoid timeout interruptions |
UPLOAD_FILE_MAX_SIZE | 500 MB | Bulk uploaded annual financial report PDF collections may exceed 100 MB per file. Reserve sufficient space to adapt to batch scenarios |
maxChunkSize | 800–1000 characters | Equipment business paragraphs usually contain three associated fields: model, revenue, and capacity. This length fully covers single-paragraph business descriptions and avoids contextual breaks |
chunkOverlap | 100–150 characters | Cross-paragraph equipment model association information requires retaining continuity. This prevents loss of key context after chunking |
CSV_IMPORT_ALLOW_COLUMNS | All columns | CSV tables exported from ordnance and equipment financial reports contain multiple columns of data including model, revenue, delivery volume, etc. Full import is required for subsequent analysis |
PARSE_REMOVE_HEADER_FOOTER | Match by template | Header and footer of exchange-traded financial reports contain unified announcement identifiers. Removing them reduces invalid chunk content |
The parameter values provided on this page are common recommendations used as a starting point for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- A 413 error is returned after uploading an ordnance and equipment financial report PDF. The cause is that the
UPLOAD_FILE_MAX_SIZEconfiguration value is smaller than the actual size of the uploaded file. For Docker deployment scenarios, synchronously adjust the request size limit of the reverse proxy within the container. - Only the first two columns of data are available after importing a CSV table exported from a financial report. The cause is that the
CSV_IMPORT_ALLOW_COLUMNSparameter is not configured. The default setting only imports the first two columns of fields. - A timeout interruption occurs when calling a custom parsing service. The cause is that the
PARSE_FILE_TIMEOUT_SECONDSconfiguration value is smaller than the actual required parsing time. This fails to adapt to the long-document parsing requirements of ordnance and equipment financial reports.
How to Verify Proper Configuration
- Upload a single 100-page ordnance and equipment financial report PDF. Check whether the parsing time is within the configured
PARSE_FILE_TIMEOUT_SECONDSrange to confirm the timeout setting is effective. - Import a CSV table exported from a financial report. Check whether all fields specified in the configuration are fully imported to confirm the CSV column configuration is correct.
- Initiate a batch upload test. Check that the uploaded file size does not exceed the
UPLOAD_FILE_MAX_SIZElimit to confirm the upload configuration is effective. - View the parsed chunk content. Confirm that equipment model and revenue data are not split into different chunks to confirm the chunking parameter configuration is reasonable.
