What the data for this category looks like
Plastic and rubber research report data comes from public reports released by the China Plastics Processing Industry Association and China Rubber Industry Association, segmented chemical industry research reports from securities firms, and documents from commodity spot trading platforms. Two update rhythms apply to the data: weekly spot tracking reports are updated every week. In-depth reports on industry supply and demand and capacity adjustments are released as needed. Document structures include industry overview, supply and demand balance sheet, price trends (units include yuan/ton, ten thousand tons), brand performance parameters, and policy impact analysis. Some research reports include embedded monthly production data tables and trend charts.
Constraints Imposed by These Characteristics on Deployment and Upgrade
Deployments must adapt to multiple document parsing rules due to the multi-source and multi-format nature of plastic and rubber research reports. For reports with embedded tables, structured parsing plugins must be enabled to preserve fields and units. Vector databases must support incremental updates and scheduled synchronization task configuration for weekly spot data and on-demand in-depth reports. This avoids resource consumption from full reindexing. Single in-depth research reports can contain tens of thousands of words. Deployments must adjust document segmentation and context window parameters to prevent information loss from content truncation. When adding new data sources during upgrades, matching thresholds for recall strategies must be adjusted synchronously. This adapts to text similarity differences between research reports from different sources.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Single in-depth research reports have large word counts, requiring sufficient parsing time |
maxContext | 8000–12000 characters | Adapts to long text content of single research reports and retains complete contextual associations |
recall count | Top 10–15 results | Covers valid information from multi-source reports and avoids missing core data for plastic and rubber segmented categories |
rerank return count | Top 5–8 results | Filters low-correlation content and focuses on core parameters and market information for plastic and rubber |
UPLOAD_FILE_MAX_SIZE | 2000 MB | Accommodates batch-imported industry research reports and historical data documents |
SCHEDULER_SYNC_INTERVAL | 604800 seconds (7 days) | Adapts to weekly update rhythms for research reports and reduces unnecessary indexing resource consumption |
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, and it is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Port isolation between login and sharing services is not configured, allowing management pages to be accessed via unauthenticated share links. The symptom is that share links redirect directly to the system login interface. The cause is that
FASTGPT_PORTandSHARE_SERVICE_PORTare not set to different ports, and reverse proxy path isolation rules are not configured. - The backend does not display deployed rerank models. The symptom is that no new rerank model option appears in the model list. The cause is that model configuration files are not mounted to specified container paths, or corresponding model names are not added to the
MODEL_LISTconfiguration item. - A specified model version is configured, but the actual called version does not match. The symptom is that call logs show the used model version differs from the configured one. The cause is that correct model identifiers are not selected in conversation chain configurations, or environment variables do not correctly override default model versions.
How to Verify Successful Configuration
- Upload a plastic and rubber research report with over 10,000 words, and confirm no truncation prompt appears in parsed text.
- Navigate to the model configuration page and confirm deployed rerank models appear in the optional list.
- Submit a research report retrieval request, and verify returned result fields include units such as yuan/ton and ten thousand tons.
- View scheduled synchronization task logs, and confirm weekly updated research report data has been automatically synchronized to the vector database.
