What the data for this category looks like
Data sources for chemical fiber research reports include domestic chemical fiber industry association public statistical data, securities firm chemical industry research reports, and spot quotation data from compliant commodity trading platforms. Update frequencies fall into three categories:
- Spot price data updates daily
- Industry supply and demand monthly reports are released monthly
- In-depth research reports are released according to the research team's schedule
Document structures include industry overview, supply and demand analysis, price trends, downstream demand analysis, and other sections. Some in-depth research reports include Excel-format raw data table attachments, with fields including upstream and downstream industrial chain prices, monthly output, production capacity scale, and more. Units are mostly yuan/ton and ten thousand tons.
Constraints on Tool Calling and Plugins
Chemical fiber research reports include real-time spot data updated daily, monthly structured supply and demand reports, and unstructured analysis text. Tool calling must support both real-time data pulling and multi-format document parsing.
The chemical fiber industrial chain has high upstream and downstream correlation, so tools must support cross-data source linkage. Examples include combining upstream raw material prices with downstream segmented category demand data. There are many segmented categories, so tools must support filtering recall results by category to avoid mixing irrelevant data.
In-depth research reports include Excel attachments with multiple sets of industry numerical data. Plugins must have structured data extraction capabilities to fully obtain core research report data.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Excel attachments included in chemical fiber research reports usually contain multiple sets of industrial data tables, which take a long time to parse. The default timeout is insufficient for complete parsing |
RECALL_CHUNK_SIZE | 800–1200 characters | Supply and demand analysis paragraphs in chemical fiber research reports are usually long. Too short segmentation will break data correlation, while too long will exceed the context window |
TOOL_CALL_MAX_RETRIES | 3 times | Commodity data interfaces may fail due to network fluctuations. Insufficient retry times will lead to tool call failure |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Some in-depth research reports include large industrial chain database attachments, and the default limit cannot cover complete data uploads |
SIMILARITY_THRESHOLD | 0.75–0.85 | Chemical fiber industry terminology is highly professional, so a high similarity threshold is required to filter irrelevant recall results and avoid accidental recall of non-chemical fiber category research reports |
TOOL_ALLOWED_DOMAINS | Domestic chemical fiber industry association interfaces, compliant commodity trading platform domain names | Restrict the data source scope of tool calls to avoid calling non-compliant interfaces for data acquisition |
The parameter values provided on this page are common recommended starting points for configuration. The actual values are affected by material form, data volume and business rules. Specific issues require specific analysis, and it is recommended to test on your own samples before finalizing.
Three Common Misconfigurations
- Symptom: Tool call returns
413 Request Entity Too Largeerror code. Cause: TheUPLOAD_FILE_MAX_SIZEconfiguration was not adjusted, and the uploaded chemical fiber research report Excel attachment exceeds the default limit. - Symptom: No results returned after tool call, and no call record can be found in the system log. Cause: The
TOOL_CALL_LOG_ENABLEconfiguration was not enabled, and tool call logging was not activated, making it impossible to troubleshoot OneAPI-class tool call failures. - Symptom: The published non-logged-in application cannot obtain user identification when calling tools. Cause: The
PASS_USER_ID_TO_TOOLparameter was not enabled in the tool call configuration, causing the tool to fail to receive user ID information.
How to Verify Successful Configuration
- Upload a chemical fiber research report Excel attachment with a single volume exceeding 500 MB, check that the upload progress bar completes normally and no file size limit exceeded prompt appears.
- Initiate a chemical fiber research report retrieval request, check the system log to confirm that tool call records and structured data extraction results are visible.
- Carry a test user ID when calling the tool interface, check that the tool end can normally receive and identify the user identification.
- Simulate a knowledge base question and answer request on the Pad side, confirm that the interface can normally return retrieved chemical fiber research report data with no cross-domain errors.
