What the data for this category looks like
Feed industry financial report data mainly comes from publicly disclosed periodic reports of listed companies, operation briefs released by industry associations, and operating announcements independently issued by enterprises. Update cycles follow fixed quarterly and annual schedules. Industry briefs are updated monthly or quarterly. Most documents are in PDF format, containing nested tables, long text paragraphs and chart descriptions. Some annual reports include special attachments for raw material procurement and capacity expansion. Core fields include feed-related revenue, raw material procurement volume, per-ton feed production cost, capacity scale, and more. Common units are ten thousand yuan, ten thousand tons, and yuan/ton. Some documents mark special data for segmented feed categories.
What constraints these characteristics impose on document parsing and chunking
Nested structured tables and cross-page business data in feed financial reports can cause table splitting and misalignment during parsing. This also leads to lost data association after chunking. Fixed-cycle batch document requirements demand consistent chunking logic across the same category. This avoids fragment confusion during retrieval. Special units and segmented fields require binding fields to corresponding values during chunking. This prevents separation of units and data. Long-text supply chain analysis and professional terms must be chunked by semantic boundaries, not just character length. This preserves the integrity of business logic.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_TABLE_STRATEGY | nest_table_merge | A large number of nested tables exist in feed financial reports. This strategy merges cross-page or nested table data to avoid splitting |
CHUNK_SIZE | 800–1200 characters | Feed financial reports include long-text analysis and structured tables. This range balances semantic integrity and retrieval density |
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | Large feed annual reports include multiple attachments. This duration covers the complete parsing process |
UPLOAD_FILE_MAX_SIZE | 500 MB | Annual financial reports may include multiple industry analysis charts. This upper limit accommodates complete documents |
ENABLE_OCR_FOR_PDF | auto | Some feed financial reports are scanned PDFs. The automatic mode recognizes text and scanned content, adapting to different document formats |
CHUNK_OVERLAP_RATE | 10% | Chunking structured data requires retaining context association. This ratio prevents key information from being truncated at chunk boundaries |
The parameter values provided on this page are common starting points for configuration setup. Actual values are affected by material form, data volume and business rules. Specific issues require targeted analysis. It is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Phenomenon: After deploying Marker, logs show
ocr error, and the interface returns that file content cannot be read. Cause: Scanned PDF versions of feed financial reports have low-resolution charts or watermarks. The OCR engine cannot recognize structured table text. - Phenomenon: After configuring the knowledge base, synchronization of PPT and PDF documents fails. Cause: The parsing whitelist for the corresponding document type is not enabled. Or the PDF of the feed financial report has encrypted headers and footers, causing synchronization verification to fail.
- Phenomenon: Normal chat works after connecting to Claude 3.7, but an error occurs when adding feed financial report parsing. Cause: The
MAX_CONTEXTparameter is not configured to adapt to long-text chunking. The model context window is exceeded, causing execution to interrupt.
How to confirm the configuration is correct
- Upload a typical feed financial report PDF. Check the parsed table preview to confirm nested tables are not split.
- Upload the largest single feed financial report. Verify the parsing process does not trigger a timeout error. Check if the configured
PARSE_FILE_TIMEOUT_SECONDSduration matches actual time spent. - Compare chunked text to the original document. Confirm core fields and their corresponding units are not split and separated.
- Batch upload feed financial reports from the same batch. Verify chunking logic consistency, and avoid excessive differences in chunking boundaries between documents.
