What Data for This Category Looks Like
Chemical fiber investment research data is sourced from upstream petrochemical raw material quotation platforms, public production scheduling information from domestic chemical fiber manufacturers, customs import and export declaration data, monthly industry reports from the China Chemical Fiber Industry Association, and daily spot market transaction prices. Data update cycles vary widely: raw material prices such as PTA and MEG are updated daily, enterprise production scheduling plans are updated weekly, and industry trend reports are released monthly.
Documents include structured quotation forms (containing brand, specification model, ton price, delivery warehouse), semi-structured industry analysis documents, and unstructured policy news. Core fields include product specification, transaction unit price, and origin identifier. Common units are yuan/ton, kg/m, and similar units.
Constraints on Citation Source and Traceability
The data characteristics of the chemical fiber category impose multiple constraints on the citation source and traceability process. First, structured quotation data accounts for a large share and has clearly segmented fields. Precise matching of fields such as product specification and origin is required to complete traceability, and to avoid mixing data from different chemical fiber product brands. Second, update cycles differ significantly across data sources. Independent update timestamp verification rules must be configured for each data source, to prevent outdated raw material prices or outdated production scheduling information from being cited. Third, scattered data sources lead to inconsistent field naming. Unified field mapping rules must be configured to ensure accurate association to original data entries during traceability. Finally, mixed-type document recall must be sorted by data source priority, returning daily updated spot quotation data first, followed by monthly industry report content.
Configuration Settings
| Configuration Item | Recommended Value | Rationale | |||
|---|---|---|---|---|---|
recall_count | Top 20 entries | Chemical fiber data includes multiple data source types. Excessive recall leads to redundant context, while insufficient recall fails to cover core quotation and analysis content | |||
similarity_threshold | 0.75–0.85 | Chemical fiber product specifications have high segmentation granularity. A higher threshold is needed to filter irrelevant non-similar product data and avoid traceability errors | |||
reranked_return_count | Top 8 entries | Core spot quotation and key industry report content must be retained, balancing recall accuracy and context length | |||
citation_template | `{{source}} | {{update_time}} | {{product_spec}} | {{price}}` | Chemical fiber traceability requires clear labeling of data source, update time, product specification, and transaction unit price to meet traceability requirements for investment research scenarios |
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | Structured quotation forms typically contain multiple rows of data, with long parsing times. Extending the timeout period avoids parsing failures | |||
maxContext | 8000–12000 characters | Chemical fiber investment research requires referencing raw material prices, product quotations, and industry analysis simultaneously. A longer context can cover multi-dimensional traceability information |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require targeted analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Symptom: The system returns a
504 Gateway Timeouterror when parsing multiple structured quotation forms. Cause: ThePARSE_FILE_TIMEOUT_SECONDSconfiguration value is lower than the time required to parse the forms, causing the parsing process to time out and interrupt. - Symptom: Mixed retrieval results include chemical fiber product data of different specifications, and traceability information does not label the corresponding product model. Cause: Field matching verification rules are not enabled, and recall entries are not filtered by the
product_specfield, leading to irrelevant data being included in the context. - Symptom: When consecutively submitting investment research queries, subsequent questions cannot associate previously cited quotation data, and responses deviate from the current chemical fiber category query scope. Cause: The
maxContextconfiguration value is too small, failing to retain context information from previous traceability, leading to context window overflow and loss of key associated data.
How to Verify Proper Configuration
- Upload a single structured chemical fiber quotation document, check if the extracted fields after parsing cover core information such as product specification, transaction unit price, and update time, and confirm that the field mapping configuration is effective.
- Submit a query containing a specified product model, verify that the returned citation sources only match data for that model of chemical fiber product, and confirm that the similarity threshold and field filtering rules are working correctly.
- Submit multiple consecutive investment research queries associated with the same data source, check if subsequent responses can associate previously cited traceability information, and confirm that the context window configuration meets requirements.
- View system operation logs, confirm that no timeout errors occur when parsing batch structured documents, and confirm that the parsing timeout configuration matches actual parsing needs.
