What the data for this category looks like
Minor metal financing daily report data mainly comes from domestic non-ferrous metal spot trading platforms, futures exchanges, and industry self-regulatory organizations. Full daily post-close updates are completed by 17:00 each day. Each daily report document is arranged by commodity variety, with core fields including commodity name, financing purchase amount, financing balance, securities lending sales volume, total inventory volume, and others. Units are uniformly set as RMB ten thousand yuan and physical tons. Each data entry in the document corresponds to a unique trading period identifier and source institution number.
What constraints do these characteristics impose on the citation sources and traceability link?
The multi-source nature of minor metal financing daily reports requires the traceability link to associate each data entry with its original publishing institution, to avoid mixing data collected from different sources. The categorized layout by commodity variety requires retrieval to bind the variety identifier and traceability information, to ensure that the traceability tags of returned results fully match the corresponding data blocks. The fixed daily update schedule requires the traceability link to verify data timestamps and filter expired data older than 24 hours, to ensure the timeliness of response content. The special nature of fields and units requires traceability information to fully retain unit labels such as RMB ten thousand yuan and physical tons, to avoid information deviation caused by mixed use of cross-category data.
How to set the configuration
| Configuration Item | Suggested Value | Rationale |
|---|---|---|
chunk_size | 5000 token | Matches the average data density of a single minor metal financing daily report document, avoiding splitting too many or too few valid data entries in a single chunk |
recall count | Top 10 entries | A single minor metal financing daily report document contains 10 to 20 commodity variety data entries; recalling 10 entries can cover the target varieties of most conventional queries |
similarity threshold | 0.8 | There are few homophonous confusing items for minor metal commodity names; this threshold can accurately filter irrelevant retrieval results |
citation limit | 1500 characters | Complies with common configurations in user communities, and can carry complete traceability information such as the source, time, and fields corresponding to each data entry |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | A single minor metal financing daily report document has a large data volume, and the parsing process requires a long time to avoid parsing failure caused by early timeout |
reordered return count | Top 6 entries | Perform secondary screening on recall results to retain traceability data with high relevance to the query topic and avoid interference from redundant information |
The parameter values provided on this page are conventional recommendations used to determine the starting point for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require specific analysis, and it is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Phenomenon: After setting the
citation limitto 1500 characters, retrieval results still exceed this limit. Cause: The matching relationship betweenchunk_sizeandcitation limitwas not adjusted synchronously, and the single chunk content is too long, causing a single returned data entry to exceed the citation limit. - Phenomenon: The generated response does not include the address of the cited file. Cause: The knowledge base traceability function was not enabled, or the output format including the source file address was not configured in the system prompt.
- Phenomenon: Unit labels are missing in the traceability data returned by retrieval. Cause: The option to retain original field units was not enabled in the knowledge base parsing configuration, causing unit information to be lost from chunked data.
How to confirm the configuration is correct
- Upload a minor metal financing daily report document, check the chunked content parsed by the knowledge base, and confirm that each chunk contains complete source, time, field, and unit information.
- Initiate a query for financing daily reports of a specific minor metal commodity variety, check the citation tags of the returned results, and confirm that each citation includes the corresponding source institution and update time.
- Adjust the
citation limitto 1000 characters, initiate a query, and confirm that the total length of the returned traceability content does not exceed this setting. - For FastGPT 4.6.7, check the traceability switch status in the application configuration and confirm that the function has been enabled.
