What This Category of Data Looks Like
Data for minor metal financing daily reports comes from industry news platforms, publicly disclosed documents from futures exchanges, and aggregated financing announcements from industrial chain enterprises. It is updated daily with the previous trading day’s financing trading data. Most documents are in docx or pdf format. Their structure includes a daily overview page and per-commodity entry pages. Core content is presented in structured tables, alongside images such as market trend charts and screenshots of financing entity announcements. Fields include commodity name, daily financing scale (unit: ten thousand yuan / hundred million yuan), number of financing transactions, financing entity type, fund provider, financing term, collateral quantity (unit: ton), daily price change (unit: yuan / ton), and more.
What Constraints Do These Characteristics Impose on the Document Parsing and Chunking Link?
The mixed table and image layout requires the parsing engine to accurately identify table structures and contextual associations of images, to avoid splitting core data during chunking. The high-frequency daily update requirement means the parsing process needs batch processing capabilities, and must match a reasonable parsing time threshold for single documents. The diversity of fields and units requires establishing a binding relationship between fields and their corresponding units during parsing, to prevent mismatched units and data. Some documents contain embedded Excel-format detailed data tables, so support for simultaneous parsing of embedded Excel images and tables is needed to avoid missing content.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 120–180 seconds | A single minor metal financing daily report contains 5–15 pages, with multiple structured tables and images. Normal parsing time falls within this range |
CHUNK_SIZE | 800–1200 characters | A single daily report includes financing entries for multiple independent commodities. Chunking must preserve the integrity of per-commodity financing information, avoiding cross-commodity splitting |
ENABLE_TABLE_PARSE | Enabled | The core data of the daily report is presented in structured tables. Enabling this option preserves the association between fields and their corresponding units |
IMAGE_INCLUDE_IN_CHUNK | Bound to text context | Market charts and announcement screenshots in the daily report must be associated with the text block of the corresponding commodity, to prevent images from being separated from business context |
UPLOAD_FILE_MAX_SIZE | 500 MB | Limits the per-file upper limit in batch processing scenarios, to avoid parsing timeouts or excessive resource usage |
PARSE_IMAGE_ENABLE | Enabled | Supports extracting embedded images in the daily report and associating them with text, to avoid loss of business information related to images |
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 case-by-case analysis. Testing on independent samples is recommended before finalizing settings.
Three Common Misconfigurations
- Issue: After uploading a docx-format daily report containing images, an
Invalid image fileerror is returned. Cause: ThePARSE_IMAGE_ENABLEconfiguration is not enabled, or the image format is not supported by the parsing engine. - Issue: A timeout error occurs when batch parsing multiple daily reports, with a 504 status code returned. Cause: The
PARSE_FILE_TIMEOUT_SECONDSvalue is set too low, and does not match the parsing time required for documents with multiple tables and images. - Issue: When parsing an Excel-format detailed financing daily report, the data fields corresponding to images in the table are empty. Cause:
ENABLE_TABLE_PARSEis not enabled, and Excel embedded image association parsing is not configured, resulting in separation of tables and images.
How to Verify Correct Configuration
- A single minor metal financing daily report document containing tables and images is uploaded, and the parsed data table fields, units and values are checked against the original document.
- Image association content in the parsing results is reviewed, confirming that images and the financing information of the corresponding commodity are in the same chunk.
- 3–5 daily report documents are batch uploaded, confirming that parsing time does not exceed the set
PARSE_FILE_TIMEOUT_SECONDSvalue. - Parsing logs are reviewed, confirming that no
Invalid image fileerrors occur, and all embedded images are correctly associated.
