What This Category’s Data Looks Like
Data comes from public investment and financing disclosures and daily summary documents from defense industry associations. The data updates daily. Common document formats include Excel, text-extractable PDF, and tab-separated text files. Documents use a structured layout with fixed headers. Each entry corresponds to one single defense electronics financing event. Core fields include full financing entity name, defense industry segment classification, financing amount, financing round, disclosure date, investor entity, and post-money valuation. Financing amount units are typically ten thousand yuan or hundred million yuan. Date fields use standard Gregorian calendar formats.
Constraints for Document Parsing and Chunking
Full associated relationships between structured fields must be retained for defense electronics financing daily reports. The complete field set of a single financing event must not be split during chunking. Otherwise, subsequent retrieval loses key associated information such as segment and amount unit. Single daily documents contain a large number of entries. Long document chunking must avoid splitting across entries. Some documents use mixed financing amount units. Parsing requires unified unit conversion. Chunking must retain contextual associations between units and corresponding amounts. Multi-format input documents may include multiple worksheets. Parsing must accurately locate the target worksheet containing data to avoid parsing irrelevant content.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
PARSE_EXCEL_SHEET_INDEX | 0 or specified target worksheet index | Defense electronics financing daily reports typically store data in a single worksheet. Specifying an index avoids parsing unnecessary worksheet content |
CHUNK_SIZE | 800–1200 characters | The complete field combination text length of a single financing event typically ranges from 500 to 1000 characters. This range ensures a single event remains fully intact without splitting |
PARSE_FILE_MAX_SIZE | 50 MB | Single defense electronics financing daily report documents containing multiple days of data typically do not exceed this threshold |
ENABLE_METADATA_EXTRACTION | Enabled | Fields such as financing segment and amount unit must be extracted as metadata and bound to corresponding chunks |
OCR_ENABLED | Triggered based on document text layer status | Scanned financing daily reports require OCR recognition. This setting can be configured to automatically enable only when the document has no built-in text layer |
MAX_CHUNK_OVERLAP | 100–150 characters | Prevents loss of contextual association between chunks. Ensures information such as cross-chunk unit descriptions can be read coherently |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, 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: After an Excel-format defense electronics financing daily report is uploaded, the parsing result only includes content from some worksheets. Cause: The target worksheet index was not specified. When the first worksheet is parsed by default, the target data is stored in another worksheet.
- Symptom: Chunked content is split across multiple entries, leading to loss of associated fields such as segment and amount for a single financing event. Cause: Chunk length was set too small. The length exceeds the text length of a single financing event, forcing splitting of the complete field combination.
- Symptom: Corresponding metadata such as investor and defense industry segment cannot be retrieved after accessing chunks. Cause: Metadata extraction configuration was not enabled. Document fields were not bound to chunks.
How to Verify Proper Configuration
- A test defense electronics financing daily report document must be uploaded. The parsed field list must be reviewed to confirm all preset core fields are correctly extracted.
- Chunking results must be reviewed to confirm each chunk contains complete information for a single financing event, with no cross-event splitting.
- Chunk metadata must be checked to confirm each chunk is bound to corresponding fields such as defense industry segment and financing amount unit.
- Custom parsing rules (if configured) must be tested to confirm custom header formats are correctly identified, with no missing or misaligned fields.
