What the data for this category looks like
Investment research teams source plastics and rubber industry data from multiple places. These include spot and futures quotes on regulated commodity exchanges, industry survey data from national industry associations, import and export statistics from national customs authorities, real-time data from third-party commodity quotation platforms, and in-depth industry research reports from professional institutions. Data updates follow four cycles. Daily updates cover real-time spot quotes. Weekly updates include industry weekly reports and inventory data. Monthly updates cover import and export and warehouse receipt statistics. Quarterly updates deliver in-depth analysis reports. Document types fall into three categories. Structured tables include fields such as brand, delivery grade, premium/discount, and warehouse receipt quantity, with units mostly yuan/ton, ten thousand tons, and percentage. Semi-structured industry analysis manuscripts and unstructured market dynamic content make up the remaining types.
Constraints on citation source and traceability
The data’s characteristics create multiple constraints for the citation source and traceability process. A high share of structured data requires precise matching of specific fields and release cycles during traceability. This prevents confusion between quote data for different delivery brands. Multiple data sources have widely varying update frequencies. Traceability information must clearly label data source types and release times. This stops teams from using expired data to support investment research conclusions. Single document lengths vary drastically. Ranges span from hundreds of-word instant quote sheets to dozens of pages of in-depth research reports. Traceability tools must support position marking for both short and long document slices. Fields include professional terms and industry-specific definitions. Traceability systems must retain original field names. This lets investment research personnel quickly verify data accuracy and compliance.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
segment length | 1000–1500 characters | Adapts to the plastics and rubber industry’s document structure, which includes both short quote sheets and long-cycle research reports, and retains the integrity of table and paragraph information |
recall count | Top 8–12 | Covers multiple data sources such as exchanges, industry associations, and customs authorities, and avoids exceeding context limits that affect response coherence |
citation limit | 1200–1800 token | In-depth plastics and rubber research reports have relatively high effective information density, reserving sufficient space to display complete traceability content |
similarity threshold | 0.72–0.85 | Filters low-relevance historical archived data, and accurately matches keywords such as brand and delivery period in current investment research questions |
citation source display toggle | Enabled | Meets compliance and verifiability requirements for investment research scenarios, and clearly labels data sources |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Adapts to the parsing duration of large industry research reports, and avoids truncating key content due to timeout |
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 settings.
Three Common Configuration Errors
- Symptom: After setting the
citation limitto 1500, the returned result still exceeds this limit. Cause: In FastGPT 4.6.7, themaxContextparameter is not adjusted synchronously, or the chunk length is set too large, causing a single chunk to occupy too much context quota. - Symptom: The cited content does not include file addresses or publishing organization information. Cause: The full path display option for
citation source formatis not enabled, or document metadata fields are not extracted during parsing. - Symptom: A
504 Gateway Timeouterror is triggered when parsing large plastics and rubber industry research reports. Cause: ThePARSE_FILE_TIMEOUT_SECONDSsetting value is too low, and sufficient parsing duration is not reserved.
How to Verify Correct Configuration
- Upload a plastics and rubber spot quote sheet, launch a targeted query, and check whether the number of citations in the returned result matches the
citation limitsetting. - View the citation source module in the response, and confirm that it includes metadata information such as file path, publishing organization, and release date.
- Adjust the
similarity thresholdto 0.6, launch the same query, observe the change in the relevance of recall results, and verify that the parameter takes effect. - Upload a plastics and rubber industry research report with more than 100 pages, and check whether the traceability information of the parsed slices includes chapter numbers and page numbers.
