What the data for this category looks like
Aerospace equipment financing daily report data comes primarily from public announcements of military industrial groups, project notices from aerospace research institutes, military industry research reports from securities markets, and government procurement information for aerospace equipment. The update schedule is one daily report per workday. Some monthly summary documents are updated weekly. Most single documents are in Excel or PDF format. Excel versions include fields such as equipment model, contractor, financing amount, financing method, and disclosure date. Amount units are mostly ten thousand yuan or hundred million yuan. PDF versions contain structured industry financing summaries, with attached project detail tables.
What constraints these characteristics impose on document parsing and chunking
Different data formats require the parsing module to support multiple file types. Excel versions have multiple columns of detailed information, which can cause automatic chunking to truncate single financing records. Nested tables in PDF versions may lead to misaligned fields after parsing. Daily updated batch document requests require parsing timeout settings to match the processing time of single files, to avoid batch task interruptions. Specialized model naming and unique amount units require retaining field correlation during chunking. This avoids splitting contractors and financing amounts into different segments, which would reduce subsequent recall accuracy.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
segment length | 800–1200 characters | A single financing record in aerospace equipment financing daily reports includes multiple fields. This range can fully contain a single detailed entry and its associated content, avoiding split breaks |
PARSE_EXCEL_MERGE_CELLS | Enabled | Excel documents for aerospace equipment financing daily reports often include merged headers. Enabling this setting correctly identifies column attribution, avoiding field misalignment |
CHUNK_OVERLAP_RATE | 10% | Retains the correlation between specialized models, contractors, and financing amounts, preventing information loss across segments |
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | Adapts to the needs of batch processing multiple daily report documents, reserves sufficient parsing time, and avoids task interruptions |
UPLOAD_FILE_MAX_SIZE | 200 MB | Adapts to the size limit of monthly summary aerospace equipment financing daily reports, supporting complete upload and parsing |
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 the configuration.
Three Common Misconfigurations
- After uploading an Excel-format aerospace equipment financing daily report, the parsing result has misaligned multi-column fields, and some contractor fields are empty. The cause is that the
PARSE_EXCEL_MERGE_CELLSconfiguration is not enabled. This prevents recognition of merged headers in the document, leading to incorrect column attribution identification. - After batch uploading multiple PDF versions of aerospace equipment financing daily reports, automatic chunking splits a single financing record into two segments. Subsequent question answering cannot associate complete information. The cause is that the
segment lengthsetting is too small, failing to reserve enough characters to accommodate the multi-field content of a single record. - Extracted fields after parsing the document contain extra punctuation, which cannot execute normally when generating SQL queries. The cause is that the attached configuration for retaining redundant original punctuation is not disabled. This causes the extracted content to damage SQL syntax structure.
How to Verify Correct Configuration
- Upload a single Excel document of an aerospace equipment financing daily report, check the parsed field list, confirm that fields such as contractor and financing amount are not misaligned, and verify that the relevant configurations take effect.
- Upload a PDF document containing complete financing records, check the chunking results, confirm that a single financing record is not split into multiple segments, and adjust the corresponding configuration based on actual content.
- Batch upload 3 to 5 daily report documents, check the task queue status, confirm that there are no timeout errors, and verify that the timeout configuration adapts to batch processing requirements.
- Extract the parsed segment content, check whether the fields contain invalid punctuation, and adjust the relevant configuration to ensure content compliance.
