What the data for this category looks like
Data sources for baijiu financing daily reports include daily financing summary documents from vertical baijiu industry media, public corporate financing filing documents from local financial regulatory bureaus, and public financing announcements from baijiu manufacturers and distributors. Update frequency is mostly daily. Some monthly industry financing summary documents are updated weekly. Document formats cover XLSX spreadsheets, PDF reports, Word organized documents, and PPT presentation materials. Core content primarily uses structured spreadsheets. Some documents include text-and-image financing project descriptions. Fields include full financing entity name, financing scale (unit: ten thousand yuan or hundred million yuan), financing method, fund provider type, implementation date, and baijiu category segment tags. Some documents also include regional distribution fields for financing projects.
What constraints these characteristics impose on document parsing and chunking
Baijiu financing daily reports use structured spreadsheets as their core carrier. Mixed multi-format document types require the parsing module to support multiple file formats, especially multi-sheet content in XLSX files and text-and-image mixed data in PPT files. Daily updated batch document scenarios carry risks of large individual file sizes and batch upload timeouts. Fields include financing scale with units and segment category tags. The binding relationship between fields and corresponding data must be retained during chunking to avoid broken data associations caused by splitting table rows. Some older exported documents use non-UTF-8 encoding, which triggers parsing errors. Additionally, baijiu financing entities may use both abbreviations and full names. The parsing module must extract full entity information to avoid missing information in subsequent knowledge base retrieval.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 300-600 seconds | XLSX multi-sheet documents for baijiu financing daily reports usually contain a large number of rows, leading to long parsing times. This value adapts to most batch parsing scenarios |
UPLOAD_FILE_MAX_SIZE | 500-1000 MB | Monthly summary documents uploaded in batches may reach large sizes. This value covers most daily upload requirements |
maxChunkSize | 800-1200 characters | Retain the field association of financing data, avoid breaking data by splitting complete table rows, and adapt to the structured spreadsheet content of baijiu financing daily reports |
PARSE_ENCODING | Auto-detect | Some older documents use windows-1252 encoding. Auto-detection adapts to multiple encoding scenarios and avoids parsing errors |
enable_multi_sheet_parse | Enabled | Most XLSX documents for baijiu financing daily reports are divided into sheets by region or financing method. Full parsing of all sheet content is required |
chunk_overlap | 100-150 characters | Retain the contextual association of key fields such as financing entities and dates, avoiding key information being disconnected after chunking |
The parameter values provided on this page are general recommendations to serve as a starting point for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing the configuration.
Three common mistakes
- Symptom: After uploading a baijiu financing daily report in XLSX format, fields and data in multiple rows of the parsing result are misaligned, and some row data is missing. Cause: The
enable_multi_sheet_parseconfiguration is not enabled, or the chunk length is set too small, splitting complete table row data. - Symptom: A "the argument ‘windows-1252’ is invalid encoding" error appears during document parsing. Cause:
PARSE_ENCODINGis not configured for auto-detection, and the default UTF-8 encoding is used to parse old documents with non-standard encoding. - Symptom: Parsing tasks time out and fail when uploading multiple baijiu financing daily report documents in batches. Cause: The value of
PARSE_FILE_TIMEOUT_SECONDSis set too small, failing to adapt to the parsing time of multi-sheet documents.
How to confirm the configuration is correct
- Upload a test baijiu financing daily report in XLSX format, check if the number of sheets in the parsing result matches the source file, to confirm that the
enable_multi_sheet_parseconfiguration is effective. - Check the parsing logs to confirm that no errors occur during the encoding detection phase, verifying that the auto-detection configuration for
PARSE_ENCODINGworks properly. - Upload a single large-volume document, monitor the parsing task duration, and adjust
PARSE_FILE_TIMEOUT_SECONDSto a value that allows the task to complete. - Split a section of text containing a complete financing table row, check if the chunking result retains the complete association between fields and corresponding data, verifying the rationality of the
maxChunkSizeandchunk_overlapconfigurations.
