Data characteristics for this category
Sources for industrial metals research report data include industry associations, futures exchanges, securities firm research institutes, and professional information platforms. Update frequencies vary: spot market prices are updated daily, futures data is posted after market close, standard reports are released weekly or monthly, and in-depth reports are updated on an irregular basis.
Document structures contain structured market data modules, supply and demand analysis content, policy interpretation sections, and price forecasting sections. Fields include product prices (most often quoted in USD/ton or CNY/ton), total inventory (measured in tons), monthly output (measured in 10,000 tons), plus metadata such as publishing institution and publish time.
Constraints on deployment and upgrade
High-frequency structured data and long-text analysis content coexist in industrial metals research reports. Deployments must support both structured field extraction and unstructured content parsing. High-frequency spot and futures market updates require scheduled synchronization tasks to avoid data lag that harms retrieval timeliness. Fields with multiple units need unified formatting during preprocessing. Unformatted data causes embedding vector deviation. Long documents require adjustments to parsing and context window configurations to prevent content truncation and loss of critical information.
Configuration settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Industrial metals in-depth research reports have long length, require sufficient parsing time |
maxContext | 8000–12000 characters | Cover complete information from structured data and long-text analysis in reports |
RECALL_TOP_N | Top 8–12 results | Match the feature of multiple industrial metals sub-varieties, retrieve enough relevant documents |
EMBEDDING_BATCH_SIZE | 32–64 | Adapt to embedding model memory usage for local CPU server deployment |
SIMILARITY_THRESHOLD | 0.72–0.8 | Filter non-relevant highly professional content, ensure retrieval accuracy |
UPLOAD_FILE_MAX_SIZE | 500 MB | Support uploading complete industry in-depth research report files |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material format, 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 configuration errors
- Phenomenon: Workflow debugging returns
workflow error {"message":"Dangerous behavior"}. Cause:ALLOWED_DANGEROUS_FUNCTIONSis not configured, or resource access scope is not restricted when calling a local embedding model. - Phenomenon: Rule traceability symbols appear at the end of model conversation responses. Cause:
DEBUG_MODEremains enabled, or theRESPONSE_SOURCE_DISPLAYswitch is not configured correctly in FastGPT 4.9.13. - Phenomenon: Multiple price units such as USD/ton and CNY/kg appear in retrieved research reports. Cause: Field unit formats are not unified during data preprocessing, leading to embedding vector matching deviation.
How to confirm correct configuration
- Upload an industrial metals in-depth research report, check the document parsing log to confirm segmented results retain complete structured fields and unit information.
- Initiate a query about industrial metals supply and demand, use retrieval logs to verify the number of returned results matches the configured
RECALL_TOP_Nvalue. - Use the model debugging tool to input industrial metals-related text, confirm the local embedding model generates vectors without errors, and matching degrees align with the expected threshold.
- Disable
DEBUG_MODEthen initiate a conversation, check that no additional rule or source data traceability content appears at the end of returned results.
