What the data for this category looks like
The financial report data for the defense electronics category comes primarily from public disclosure announcements of domestic defense electronics listed companies, and regular business reports from subsidiaries of defense industry groups. Updates follow a core schedule of quarterly and annual reports, with supplementary temporary announcements including major contracts and qualification changes. Document structures include standard financial statement modules, plus dedicated fields such as military product order amounts, proportion of defense business revenue, and progress of core supporting models. Units include standard ones like ten thousand yuan and hundred million yuan, plus specialized defense industry units such as sets and propellant charge volume. A single annual report document can be dozens of pages long. Quarterly reports and temporary announcements have significant structural differences, and some content is stored as scanned documents.
What constraints do these characteristics impose on the document parsing and chunking process
The dedicated fields and structural features of defense electronics financial reports create multiple constraints for the parsing and chunking process. First, the integrity of specialized terminology and business fields must be maintained to avoid losing military product model and order-related information during parsing. Second, the coexistence of multiple types of units requires the parsing process to retain original unit labels instead of performing uniform conversions. Third, the structural differences between temporary announcements and regular reports mean fixed templates cannot be relied on for chunking, requiring adaptation to dynamic document structures. Fourth, the demand for multi-file parsing in batch analysis scenarios requires the process to have sufficient concurrent processing capabilities and timeout fault tolerance.
How to set the configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
marker_model | v0.1 | Supports parsing of complex business tables and specialized terminology in defense electronics financial reports, with stable compatibility on versions 4.8.20 and above |
chunk_size | 800–1200 characters | Defense electronics financial reports contain dense financial and business-related fields. This range preserves information integrity and avoids splitting order and corresponding model data |
chunk_overlap | 150–200 characters | Covers cross-paragraph related fields in defense electronics financial reports, such as military product revenue proportion and corresponding quarterly production capacity data, preventing context breaks |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Single defense electronics annual reports have many pages and take longer to parse. This threshold prevents routine parsing timeouts |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Supports batch uploading of multiple defense electronics financial report files, adapting to quarterly batch analysis scenarios |
enable_ocr | Enabled | Some defense electronics financial reports are released as scanned documents. OCR accurately extracts financial data and redacted business fields from tables |
The parameter values provided on this page are general recommendations to serve as a starting point 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
- Symptom: A 504 Gateway Timeout error is returned when calling the file parsing tool, or the parsing result is empty. Cause: The
PARSE_FILE_TIMEOUT_SECONDSparameter was not adjusted, and defense electronics financial report parsing exceeded the default threshold. - Symptom: Parsed chunked content loses the association between military product models and order amounts. Cause: The
chunk_sizesetting is too small, causing related fields to be split into different chunks and breaking business logic coherence. - Symptom: The built-in parsing function throws an error when using version 4.9.0. Normal functionality is restored after switching to version 4.8.20 or the
marker_images:v0.1image. Cause: The built-in parsing model in version 4.9.0 has compatibility issues with complex tables in defense electronics financial reports, requiring a switch to a stable version of the parsing image.
How to confirm the configuration is correct
- Upload a single quarterly financial report PDF from a defense electronics listed company, view the parsed chunk list, and confirm that core fields such as defense business revenue and contract liabilities are not truncated.
- Check the parsing log to confirm that the
marker_modelparameter is set to thev0.1version, with no version compatibility-related errors. - Test batch uploading of three or more defense electronics financial report files, and confirm that the upload and parsing process has no timeouts or interruptions.
- Verify that when OCR is enabled, scanned defense electronics financial reports can accurately extract financial data and business fields from tables.
