What the data for this category looks like
Paper industry research reports primarily come from public reports released by securities firm light manufacturing research teams, the National Paper Industry Information Center, and industry associations. Update cycles focus on weekly industry updates, monthly production and sales data, and quarterly capacity tracking. Temporary supplementary reports are issued when major raw material price fluctuations occur. Document structure follows a fixed format, including issuing organization, release date, price trends of core raw materials (wood pulp, waste paper), capacity, output, and inventory data for each segmented category (cultural paper, packaging paper, household paper), as well as order changes on the downstream demand side. Most data fields use tons, yuan per ton, and percentage as units. Some reports include individual plant operation data for enterprises.
What constraints do these characteristics impose on deployment and upgrade?
The high-frequency updates and temporary report nature of paper industry research reports require configuring incremental synchronization tasks during deployment. This avoids full data pulling that occupies server resources. The fixed segmented field structure requires compatibility with newly added enterprise operation data fields during upgrades. This prevents missing fields in parsing logic. The presence of long-form temporary reports requires adjusting parsing timeout and context truncation thresholds. This prevents core data from being truncated. The requirement for unified units requires verifying the consistency of data field measurement units after upgrades. This avoids unit confusion in retrieval results.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Paper industry research reports have long length; conventional parsing duration may exceed default values. Extending the timeout prevents parsing failures |
UPLOAD_FILE_MAX_SIZE | 20 MB | Most individual paper industry research report PDFs do not exceed 20 MB, while accommodating upload needs for large-sized collections |
maxContext | 8000–12000 characters | Required to cover complete raw material price and capacity data paragraphs, to avoid truncation of critical information |
Recall count | Top 8–10 entries | Segmented data in paper industry research reports is scattered across different paragraphs; appropriate recall ensures coverage of core indicators |
Similarity threshold | 0.75–0.85 | Filters low-relevance general industry discussions, retaining report fragments directly related to paper industry segmented categories |
PARSE_CHUNK_SIZE | 1500–2000 characters | Single-paragraph data in paper industry research reports (such as raw material price trends) has moderate length; this chunking length preserves complete logical units |
The parameter values provided on this page are general recommendations for starting configuration points. Actual values are affected by material form, data volume, and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Symptom: Running the docker pull command returns a
404 Not Founderror, or image pull progress stalls. Cause: Domestic mirror acceleration sources are not configured. Official image repositories have restricted access in some network environments. - Symptom: After upgrading from version 4.9.0 to 4.12.3, existing research report parsing configurations fail, and some fields cannot be retrieved. Cause: Field mapping configurations for parsing rules were not updated synchronously. The new version adjusts field verification logic for research report parsing.
- Symptom: Uploading a paper industry research report shows parsing failure, with an
ETIMEDOUTerror in logs. Cause: ThePARSE_FILE_TIMEOUT_SECONDSparameter was not adjusted. The default timeout duration is insufficient for processing long-form research reports.
How to confirm configuration is complete
- Run the docker pull command to pull the specified version of the image, confirm no network errors occur to complete image pull verification.
- Upload a typical paper industry research report PDF, wait for parsing to complete, then view the parsed text fragments. Confirm that core fields such as raw material prices and capacity data have been correctly extracted.
- Initiate a research report retrieval test, enter specified paper industry keywords, check the number and relevance of returned results. Adjust recall count and similarity threshold to meet requirements.
- View the server resource monitoring panel, confirm that CPU and memory usage of parsing tasks do not exceed thresholds, to avoid insufficient resources during subsequent batch processing.
