What the data for this category looks like
The data for textile manufacturing research reports is mainly sourced from public reports from domestic industry associations, detailed sector research reports from securities firms, annual reports of listed companies’ textile divisions, and customs import and export statistical documents. Updates follow a schedule of quarterly and semi-annual regular reports, paired with temporary supplementary documents for sudden industry events. Most documents are in PDF or Excel format, with structures that include fields such as industry supply and demand data, raw material prices, downstream demand breakdowns, and corporate operating indicators. Field units use professional industrial units including yuan/ton, percentage, unit, meter, and others.
What constraints these characteristics impose on deployment and upgrade
Multiple scattered data sources require support for multi-path batch import during the deployment phase, to avoid repetitive work from manual organization. The regular update cycle requires configuring incremental synchronization logic during the upgrade phase, to reduce resource usage from full synchronization. The diversity of professional fields and units requires the parsing link to support custom field mapping and unit conversion, to avoid matching deviations caused by inconsistent units during retrieval. The combination of long documents and structured data requires adjusting parsing timeout and segmentation parameters during deployment, to ensure complete extraction of core data from research reports.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 200 MB | Single in-depth textile manufacturing research report in PDF or Excel format typically does not exceed 200 MB, to avoid upload interception triggered by oversized files |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Long document parsing requires sufficient time to complete structured extraction, to avoid task interruption from mid-process timeout |
maxContext | 8000–12000 characters | Research report content is dense and contains many technical terms; sufficient context preserves the logical relationships between data |
Recall count | Top 8 entries | Textile manufacturing research reports cover multiple dimensions including supply and demand, costs, and downstream demand; an appropriate number of recalled entries covers core retrieval scenarios |
Similarity threshold | 0.75–0.85 | Filter general industry reports, retain research report content with high matching degree for textile manufacturing sector-specific topics |
Incremental synchronization cycle | 2:00 AM daily | Securities firm research reports are typically updated outside trading hours; scheduled synchronization ensures data timeliness |
The parameter values provided on this page are general recommendations used as a starting point 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
- An error stating "parsing failed" appears when uploading Excel research reports containing raw material price data. The cause is that the
PARSE_EXCEL_SHEET_INDEXparameter is not configured. The default setting reads the first worksheet, but some research reports place valid data on the second worksheet. - Some files return a 413 status code during batch import of multiple research reports. The cause is that the
UPLOAD_FILE_MAX_SIZEsetting is smaller than the actual size of a single research report, triggering the upload size limit. - The document input function module does not display when using the feature in version 4.9.10alpha. The cause is that this test version disables the document input function by default. The corresponding configuration item must be manually enabled.
How to Verify Correct Configuration
- Upload a standard textile manufacturing research report in Excel format, check that the parsing result correctly extracts preset fields such as "pure cotton yarn price" and "loom operating rate", and confirm that field mapping is correct.
- Trigger an incremental synchronization task, check the synchronization log, and confirm that only research report files updated on the current day are newly synchronized, with no repeated processing of historical data.
- Initiate a retrieval test, enter "2024 textile export tax rebate rate adjustment", and check that the number of returned results matches the
Recall countconfiguration, and that the similarity meets the threshold requirements. - Upload a research report in PDF format exceeding 100 MB, confirm that the upload is not intercepted, and that the parsing process does not trigger timeout errors.
