What the data for this category looks like
Data sources for financial due diligence reports in the chemical fiber category mainly include upstream petroleum and petrochemical raw material ex-factory price databases, publicly monitored data from the China Chemical Fiber Industry Association, operating reports publicly disclosed by downstream weaving enterprises, and industry compliance inspection reports. Data update frequencies vary by dimension: raw material price data is updated daily, industry production capacity and inventory data is updated monthly, and enterprise operating data is updated annually. A single due diligence report document usually includes fields such as raw material grade, capacity utilization rate, inventory turnover days, and product gross margin. Units include yuan/ton, ten thousand tons, %, days, etc. The document structure is layered according to the upstream-midstream-downstream industrial chain.
What constraints do these characteristics impose on the "citation sources and traceability" link
The multi-dimensional update frequency differences require matching data collection times during traceability, to avoid mixing cross-cycle data. Fields involve multiple units, so unit information for corresponding fields must be marked during traceability to prevent parameter confusion. Data sources are scattered across different public channels, so different recall rules need to be configured for different data types. For example, prioritize recalling real-time database entries for raw material price data, and prioritize matching monthly report sources for industry association data. Some compliance inspection reports are unstructured documents, so additional segment parsing rules must be configured to accurately locate citation fragments. Due diligence report documents are lengthy, so segment length must be adapted to the content length of different data dimensions to avoid truncating critical information in citation fragments.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_SEGMENT_LENGTH | 800–1200 characters | The single-segment content of raw material price and production capacity data in chemical fiber due diligence reports usually falls within the 800-1200 character range, to avoid truncating associated information between fields and units |
RECALL_TOP_K | Top 6 entries | Data sources for the chemical fiber category are scattered, so enough entries must be recalled to cover three data dimensions: upstream raw materials, midstream production capacity, and downstream demand |
SIMILARITY_THRESHOLD | 0.75–0.85 | Most chemical fiber data fields are standardized numerical values, so a relatively high threshold is needed to filter irrelevant generalized industry content and retain precisely matched segmented data |
REFERENCE_TEMPLATE | Calibrated based on actual testing | Must adapt to the field and unit marking rules of chemical fiber reports, and embed field names and collection time placeholders in the template |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | A single chemical fiber due diligence report document usually contains integrated content from multiple data sources, so parsing takes a long time. Extending the timeout period avoids interruptions |
MAX_REFERENCE_COUNT | Top 4 entries | Citations in due diligence reports need to focus on core data, avoiding too many entries that disrupt response logic |
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, and it is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Issue: After upgrading to version
4.9.7, the citation source is not displayed at the end of knowledge base answer paragraphs. Cause: TheREFERENCE_SHOW_ENABLEswitch is not enabled, or the reference template does not use the correct placeholder format. - Issue: A
504 Gateway Timeouterror is returned when parsing chemical fiber due diligence reports. Cause:PARSE_FILE_TIMEOUT_SECONDSis not configured to a value greater than300 seconds, leading to timeout during long document parsing. - Issue: The units of recalled citation data do not match the report fields. Cause: The
SIMILARITY_THRESHOLDthreshold is not adjusted for the chemical fiber category, resulting in recall of generalized industry data with non-matching units.
How to confirm configurations are correctly set
- Upload a local chemical fiber due diligence report document, trigger knowledge base question answering, and check if citation content marked with data source, field, and unit is displayed at the end of answer paragraphs.
- Check system logs to confirm that document parsing time does not exceed the threshold set by
PARSE_FILE_TIMEOUT_SECONDS, with no timeout errors. - Compare recalled citation data with the original document content to confirm that field and unit matching meets expectations.
- Initiate multiple consecutive rounds of question answering, check that context association logic is normal, and citation sources are dynamically adjusted with conversation context.
