What the data for this category looks like
Data sources for snack food financing daily reports include third-party industry monitoring institutions, local market supervision public platforms, and official corporate announcement channels. The system updates the previous day's public financing events every early morning. There are two mainstream document formats: PDF documents are multi-page. The first page displays the daily financing overview, and subsequent pages list event details by financing round or snack food sub-category, with mixed text and image content. Excel documents are single-column event detail tables. Each row is an independent financing event, and some cells contain embedded logo images of fundraisers or investors. Core fields include financing entity name, main snack food sub-category, financing amount, investor institution, financing round, disclosure date, and document source link. The financing amount unit is uniformly ten thousand RMB.
What constraints do these characteristics impose on document parsing and chunking
The multi-format sources (mixed text-image PDFs, Excel with inline images) require the parsing module to support both text extraction and image recognition, to avoid missing structured information. The daily update schedule causes fluctuating data volume, so the system must adapt to single documents of different lengths, avoiding abnormal event splitting due to fixed chunking thresholds. Fields have clear structured attributes (financing amount, financing round), so chunking must preserve field boundaries to prevent chunks spanning multiple financing events. Scenarios where inline images are bound to text require chunking logic to associate text and image information, rather than only extracting isolated text. The number of events in a single document varies widely, so chunking granularity must balance information completeness and retrieval efficiency.
How to set the configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
PARSE_SUPPORT_IMAGE | Enabled | Adapts to inline images in PDFs and Excel, retains the associated text-image information of financing events |
MAX_SEGMENT_LENGTH | 800–1200 characters | Adapts to the number of events and the text length of a single event in daily reports, avoids cross-event splitting or overly long chunks |
PARSE_EXCEL_INLINE_IMAGE | Enabled | Processes embedded images such as fundraiser logos in Excel-format daily reports, fully restores document content |
PARSE_TIMEOUT_SECONDS | 300 seconds | Adapts to the document size and parsing complexity of single daily reports, avoids timeout interruptions |
SEGMENT_FIELD_BOUNDARY | Split by financing event ID | Strictly preserves the field integrity of each financing event, prevents chunks spanning multiple events |
UPLOAD_FILE_MAX_SIZE | 500 MB | Adapts to batch daily report upload scenarios, avoids parsing failures due to oversized 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 case-by-case analysis, and it is recommended to test on your own samples before finalizing.
Three Common Mistakes
- Phenomenon: After parsing an Excel-format daily report, embedded fundraiser logos are not extracted, and only text is displayed in cells. Cause: The
PARSE_EXCEL_INLINE_IMAGEconfiguration item is not enabled, causing embedded images to be ignored. - Phenomenon: A
504 Gateway Timeouterror is returned when parsing a large PDF daily report. Cause: ThePARSE_TIMEOUT_SECONDSparameter is not adjusted to a value adapted to the document size, resulting in parsing timeout. - Phenomenon: Chunking results include text blocks spanning two financing events. Cause:
SEGMENT_FIELD_BOUNDARYis not set to split by financing event ID, causing the chunking logic to only cut text by fixed length.
How to Confirm the Configuration Is Correct
- Upload a single test snack food financing daily report document, check whether images in the parsing results are fully displayed.
- Check that each chunk in the chunking results only contains complete field information for a single financing event.
- Adjust the
MAX_SEGMENT_LENGTHparameter, compare the number and completeness of chunks under different values, and select the configuration that meets business requirements. - Upload multiple test documents in different formats (PDF, Excel) to verify the parsing module's compatibility with multiple formats.
