What this category's data looks like
Aerospace equipment financial report data mainly comes from public periodic reports of listed companies, public white papers of the defense industry, and monthly delivery announcements from aircraft manufacturers. The update schedule is that quarterly reports are disclosed within 1 month after the end of the quarter, annual reports are disclosed within 4 months after the end of the year, and temporary announcements are released immediately corresponding to relevant events. PDF is the core document format, supplemented by multi-sheet Excel financial and business supplementary tables. Fields include delivery sorties, total revenue, total R&D investment, order amount, etc. Units are mostly sorties and RMB yuan.
What constraints do these characteristics impose on the "document parsing and chunking" link
The multi-source and multi-format features of aerospace equipment financial reports require the parsing link to support both PDF and multi-sheet Excel documents. The high-frequency update feature creates demand for batch parsing, so the system must adapt to load balancing for multi-task single batches. The mixed layout of embedded structured tables and unstructured business descriptions requires the chunking link to retain semantic connections between content, and avoid splitting tables and descriptions of the same topic into different chunks. The existence of multiple fields and differentiated units requires the parsing link to accurately identify fields and their corresponding units to avoid data confusion. The non-standard format of temporary announcements requires the parsing link to have high fault tolerance.
How to set configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
PARSE_EXCEL_SHEET_MODE | Parse all sheets and retain association relationships | Excel supplementary tables for aerospace equipment financial reports include multiple independent sheets such as balance sheets and delivery details. Retaining association relationships avoids fragmentation of business data |
PDF_PARSE_ENHANCE | Enabled | PDF documents of aerospace equipment financial reports contain multi-format tables and professional terms. Enabling enhanced parsing improves table recognition and term matching accuracy |
CHUNK_SIZE | 800–1200 characters | Financial report content includes compact financial data and long business descriptions. This range ensures complete semantic content within chunks and adapts to general context windows |
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | Single aerospace equipment financial report includes PDF main text and multi-sheet Excel attachments. Parsing time is longer than general documents |
SPLIT_BY_DOC_SECTION | Enabled | Aerospace equipment financial reports divide business segments by chapter. Chunking by chapter retains the document's logical structure and improves subsequent recall relevance |
UPLOAD_FILE_MAX_SIZE | 500 MB | Aerospace equipment financial reports often come with multiple supporting industry documents. This upper limit covers most batch upload scenarios |
The parameter values provided on this page are common recommendations used as a starting point for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis, and it is recommended to test on your own samples before finalizing.
Three common errors
- Phenomenon: Only the first sheet content is displayed after parsing Excel attachments, and the remaining sheet data is lost. Cause:
PARSE_EXCEL_SHEET_MODEis not configured to parse all sheets mode. The default logic only extracts the first sheet. - Phenomenon: After importing PPT or DOC format financial report documents, enabling
PDF_PARSE_ENHANCEhas no effect, and table recognition accuracy is low. Cause:PDF_PARSE_ENHANCEonly applies to PDF format documents. Non-PDF format documents require separate configuration of text parsing enhancement parameters. - Phenomenon: When batch uploading multiple aerospace equipment financial reports, some parsing tasks time out and fail. Cause:
PARSE_FILE_TIMEOUT_SECONDSis not adjusted to the duration adapted to aerospace equipment financial reports. The default timeout time is insufficient to complete multi-attachment parsing.
How to confirm the configuration is correct
- Upload a single Excel financial report attachment with multiple sheets, check if the parsing result includes all sheet content and corresponding names.
- Upload a PDF format financial report, compare the table recognition effect with and without
PDF_PARSE_ENHANCEenabled, and confirm whether the enhancement function is effective. - Upload a single large-volume financial report document, check if the parsing task is completed within the preset timeout period.
- Initiate a batch upload task, confirm that the number of uploaded files meets the batch upload upper limit specified in the configuration.
