What the data for this category looks like
Financial report data for the plastics and rubber industry comes from public periodic reports of listed companies on domestic and overseas stock exchanges, professional industry databases, and monthly production and sales monitoring data released by industry associations. The update cadence is as follows: annual full financial reports are disclosed once per year, quarterly reports are updated each quarter, and supporting industry monitoring data is updated monthly. Most documents are in PDF format, containing structured financial statements and industry production and sales data tables. Core fields include revenue, total production output, unit production cost, gross profit margin, total import and export volume, and similar metrics. Common units are ten thousand tons, yuan per ton, and percentage.
What constraints these characteristics impose on deployment and upgrade
Plastics and rubber financial reports and supporting industry data have large individual file sizes and high update frequencies, which create multiple constraints for deployment and upgrade. Differences in units across multiple data sources require configuring unified field mapping and unit conversion rules during deployment, to avoid unit confusion in analysis results. Frequently updated quarterly and monthly data require adapting incremental parsing and vector storage incremental synchronization logic. During upgrades, the original incremental update configuration must be compatible, to prevent excessive resource usage caused by full reprocessing. A high proportion of structured reports requires adjusting the table extraction priority of document parsing, to avoid parsing timeouts or content loss.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600–900 seconds | Single financial report PDF contains multiple pages of structured reports with large file sizes, requiring extended parsing timeout |
UPLOAD_FILE_MAX_SIZE | 2000 MB | Supports importing complete annual financial reports and supporting industry data files, to avoid upload failures for large files |
maxContext | 1500–2000 characters | Financial report text includes long paragraphs of financial explanations, requiring an expanded context window to retain complete semantics |
| Similarity threshold | 0.75–0.85 | Filters low-relevance industry data fragments, to avoid redundant information interfering with financial report analysis |
| Number of recalled entries | Top 8–10 entries | Financial report analysis needs to cover core financial indicators and industry-related data, appropriately increasing recall volume to ensure complete information |
EMBEDDING_BATCH_SIZE | 32 | Adapts vector generation batches for large-volume documents, balancing parsing speed and resource usage |
The parameter values provided on this page are common recommended starting points for configuration. 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 values.
Three common mistakes
- Symptom: An
internal server errorpop-up appears when importing the financial report analysis plugin. Cause: ThePARSE_FILE_TIMEOUT_SECONDSparameter was not adjusted, and parsing timeout for large-volume financial reports triggers a server-side error. - Symptom: Model vendor icons fail to load after updating the version. Cause: The original static resource mapping configuration was not retained during the upgrade, or the icon file path depended on by the frontend was not updated synchronously.
- Symptom: Knowledge base disk usage exceeds expected levels. Cause: Incremental vector storage rules were not configured, and full re-generation of embedding vectors causes duplicate disk space usage from original files, split file chunks, and embedding vector data.
How to confirm the configuration is correct
- Upload a typical plastics and rubber financial report PDF, check that the parsed text contains complete financial tables and industry data fields, and verify that parsing time falls within the range specified by the timeout parameter.
- View the knowledge base disk usage statistics, confirm that only three types of data are present: original files, split file chunks, and embedding vectors, with no duplicate stored content.
- Restart the service and verify that model vendor icons load normally, with no loading failure prompts.
- Trigger an incremental update task, check that only newly added financial report data is synchronized to the knowledge base, and no full re-parsing is triggered.
