What the data for this category looks like
Chemical fiber research reports are primarily sourced from industry professional institutions, commodity information platforms, and securities research departments. Updates follow a monthly or weekly schedule, with supplementary releases issued during sudden industry changes. Document structure includes overall industry trends, supply and demand data for core categories, price fluctuation records, downstream application scenario analysis, and relevant policy summaries. Fields include output, operating rate, price, import and export scale, and inventory turnover cycle for core categories, with units of ten thousand tons, capacity reference dimension, yuan/ton, ten thousand tons, and days respectively.
Constraints on multi-turn dialogue and prompt engineering
The decentralized sources and varied update cycles of chemical fiber research reports require that multi-turn dialogue clearly define the data source release cycle and institution type, to avoid retrieving conflicting data across cycles. Documents include independent data modules for multiple sub-categories, so multi-turn dialogue must gradually guide users to focus on specific sub-categories to reduce retrieval of non-target data. Fields include multi-dimensional quantitative indicators, so prompt engineering must clearly specify statistical scope to prevent response deviations caused by differences in statistical rules across institutions. Some research reports include unstructured industry charts, so multi-turn dialogue must support users to supplement explanations of the specific indicators corresponding to the charts, to ensure information alignment.
Configuration settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 8000–12000 characters | The length of a single chemical fiber research report ranges from 5000 to 8000 characters. Multi-turn dialogue needs to retain 3-4 rounds of context, with reasonable buffer space reserved. |
RECALL_TOP_N | Top 6–8 entries | The number of chemical fiber sub-category research reports is moderate. Excessive entries will cause context overload, while insufficient entries will fail to cover all relevant information. |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Some research reports contain nested tables and long text paragraphs, which take longer to parse. This setting avoids mid-interruption that causes data loss. |
PROMPT_TEMPLATE | First confirm the specific chemical fiber category and data cycle of the query, then answer based on the specified statistical scope | There are significant differences in statistical scope across chemical fiber research reports. Multi-turn dialogue must first clarify boundaries to avoid response deviations. |
RERANK_TOP_N | Top 3–5 entries | Retain the most relevant research report fragments after reranking, filter redundant information, and adapt to the compact context requirements of multi-turn dialogue. |
UPLOAD_FILE_MAX_SIZE | 200 MB | A single chemical fiber research report PDF is mostly 10-50 MB. Reserve reasonable storage space for batch upload scenarios. |
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 specific analysis. It is recommended to test on your own samples before finalizing settings.
Three common configuration mistakes
- Issue: After uploading a research report PDF, multi-turn dialogue does not call the uploaded document content, and only responds based on the general knowledge base. Cause: The switch to limit the knowledge base scope is not enabled, or the uploaded file is not correctly parsed into structured text.
- Issue: Response lag occurs during multi-turn dialogue, with no return exceeding the preset threshold. Cause: The context window parameter is set too large, or the number of retrieved entries is too high, leading to overload of context processing and data retrieval.
- Issue: A
400 invalid imageerror is returned when calling the API for multimodal research report analysis. Cause: The uploaded research report screenshot is not converted to a format that meets interface requirements, or image metadata is not correctly passed in multi-turn dialogue.
How to verify correct configuration
- Upload a single chemical fiber research report, submit a query containing specific category data, and check whether the response references content from the uploaded document.
- Submit two progressive queries, and verify that the system retains the details from the prior query without requiring repeated background information.
- View the parsing log to confirm that the uploaded research report text fields are complete, with no abnormal truncation or garbled characters.
- Submit a query targeting research report charts, and verify that the interface can normally return analysis results.
