What the data for this category looks like
The data for publishing financing daily reports comes primarily from industry regulatory disclosure documents, official announcements from publishing institutions, and professional information platforms. Updates are released daily. Each daily report includes all financing events in the publishing field for that day. Most documents are in PDF format, with some being PDFs exported from structured web pages. The overall structure includes a fixed header (daily report name, release date) and a two-column list of financing events in the main body. Each event contains fields such as full entity name, financing round, financing amount, investor list, and disclosure date. Financing amounts are marked with units of ten thousand yuan or hundred million yuan. Some events include embedded announcement screenshots or tables.
What constraints these characteristics impose on document parsing and chunking
Daily batch document updates require the parsing process to support scheduled triggers and batch queue processing. This prevents single-file parsing timeouts. Fixed fields and structured content require prioritizing structured field extraction rather than full text scraping, to reduce interference from redundant data. Mixed format features (PDF main text, embedded tables, a small number of announcement images) require support for text block extraction, structured table conversion, and OCR text recognition for images. Fields with financing amounts and units require associating numerical values with units during parsing, to avoid losing unit information. Differences between daily report templates require chunking by event boundaries instead of using a fixed character count. This ensures each chunk contains complete financing event information.
How to Configure Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
PARSE_OCR_ENABLE | Enabled | Financing daily report PDFs often contain embedded announcement screenshots or scanned content. OCR is required to recognize text within images |
PARSE_TABLE_STRUCTURE | Enabled | Daily reports include table content such as investor lists and amount details. Structured conversion preserves field correspondence |
maxChunkSize | 800–1200 characters | Each financing event contains 5-8 fields. Cutting by character count ensures a single chunk holds a complete event and avoids cross-event chunking |
chunkOverlap | 50–80 characters | Retain overlapping content between adjacent chunks to prevent key information from being split at chunk boundaries |
UPLOAD_FILE_MAX_SIZE | 50 MB | Single publishing financing daily report PDFs typically do not exceed 20 MB. This setting reserves sufficient space for batch upload scenarios |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Batch parsing multiple daily reports requires sufficient timeout time to avoid timeout errors caused by a large number of files |
The parameter values provided on this page are common recommended 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 settings.
Three Common Configuration Mistakes
- Symptom: Text content from PDF embedded images is missing from knowledge base recall results. Cause: The
PARSE_OCR_ENABLEconfiguration is not enabled, and image text recognition is not activated. - Symptom: A single complete financing event is split into multiple chunk fragments. Cause: Chunk length is set too small, or the chunk unit is incorrectly configured as tokens instead of characters, leading to truncation of event boundaries.
- Symptom: Parsed financing amount fields only show numerical values, without units such as ten thousand yuan or hundred million yuan. Cause: Structured table parsing is not enabled, or field association rules are not configured, causing structured fields and unit information to be separated and lost.
How to Verify Configurations Are Set Correctly
- Upload a test daily report PDF that includes embedded tables and images. Check if parsed tables retain field correspondence, and if image text is extracted normally.
- Review the chunk result list. Confirm each chunk contains complete financing event information, with no cross-event cutting.
- Check parsing logs to confirm there are no file timeout or parsing failure error records. Ensure the configuration status of
PARSE_OCR_ENABLEandPARSE_TABLE_STRUCTUREmatches expectations. - Adjust the chunk length configuration, then compare chunk results across different lengths to confirm single-chunk content meets business requirements.
