What the data for this category looks like
Electronic component financing daily report data mainly comes from industry supply chain announcement platforms, securities firm sector-specific research reports, local industry and information department financing filing documents, and listed companies' quarterly financing announcements. The update rhythm is daily; some cross-regional summary documents are updated weekly. Most documents are in PDF or Excel format, with six core fields: component model, supplier entity, financing amount, financing round, release date, and affiliated subcategory. Financing amount units are uniformly ten thousand yuan or hundred million yuan. Model fields include manufacturer prefixes and specification parameter suffixes.
Constraints imposed by these characteristics on document parsing and chunking
Daily high-frequency data updates require parsing processes to support rapid batch file processing, and avoid parsing interruptions due to timeouts. Format differences across multiple source documents require the parsing module to support PDF table extraction and Excel structured reading, and avoid data loss from failed format adaptation. Component model fields contain long strings of specification parameters. Using a general fixed character count for chunking directly will split complete model information. Field integrity for individual data entries must be prioritized. Financing amounts may use both ten thousand yuan and hundred million yuan units. Parsing must automatically identify units and perform unified conversion, to avoid unit confusion during subsequent chunking. Weekly summary documents have larger data volumes. Chunking must support splitting by data entries instead of fixed character counts, to preserve the integrity of individual financing information.
How to configure the settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Electronic component financing daily reports have many data entries per file; 600 seconds covers batch parsing and format conversion processes |
maxChunkSize | 800–1200 characters | Avoid splitting long fields such as component models and financing amounts, while ensuring contextual relevance after chunking meets retrieval requirements |
chunkOverlap | 100–150 characters | Preserve key information connections such as model and round between chunks, avoid losing context across chunks |
PARSE_EXCEL_ENABLE | Enabled | Adapt to standardized daily report documents in Excel format, directly extract structured table data to reduce manual parsing errors |
tableExtractMaxRowsPerBlock | 10–15 rows | Table rows per chunk adapt to the number of entries per page of financing daily reports, avoid overloading single chunks |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require case-by-case analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Symptom: For local deployments, after uploading a file, the parsing node shows no log output or displays a
Parsing failedstatus. Cause: ThePARSE_FILE_TIMEOUT_SECONDSconfiguration value is too low, causing batch file parsing to be terminated by timeout before completion. - Symptom: After uploading an Excel-format financing daily report, only partial entry data is captured. Cause:
PARSE_EXCEL_STRICT_MODEis not enabled, causing merged cells, hidden columns or specially formatted fields in Excel to not be fully extracted. - Symptom: The Markdown-format financing table output by the model is truncated when displayed, with
...[hide 38432 char]shown at the end. Cause: ThemaxChunkSizeconfiguration value is too small, causing individual complete financing information to be split across multiple chunks, preventing full content recall during retrieval.
How to Confirm the Configuration is Correct
- Upload a single standard electronic component financing daily report file, check if the parsing logs show
Table extraction completedandChunk generation successful, and verify that the number of chunks in the logs matches the expected number of entries. - Randomly select 3-5 financing entries, check that the parsed data fields include core information such as component model and financing amount, with no missing or misplaced content.
- Adjust the
maxChunkSizeconfiguration, re-upload the test file, and check that the chunked content retains complete individual financing information, with no split models or amounts. - Check the Docker deployment service logs, confirm there are no timeout error messages such as
slow operation xxxxms, and verify that the MongoDB response time is within normal ranges.
