Citation Source and Traceability for Chemical Fiber Research

What the data for this category looks like

Data for this category comes primarily from public statistics released by the China Chemical Fiber Industry Association, petrochemical industry research reports from leading securities firms, real-time quotes from commodity spot trading platforms, and regular and interim announcements from listed companies.

Update frequencies vary by data source:

Industry association statistics are released monthly
Securities firm research reports are updated alongside industry events and earnings report deadlines
Spot quote data is updated daily

Typical document structures include overall industry overviews, upstream and downstream supply and demand data for the industrial chain, core product specification parameters, price trend analysis, and policy impact interpretations.

Clear field and unit classifications apply: output for core products such as polyester filament and PTA is measured in ten thousand tons, spot prices in yuan per ton, and production capacity in ten thousand tons per year. Product specifications cover physical parameters including fiber fineness and breaking strength, with units of decitex and newtons per tex.

What constraints do these data characteristics impose on citation traceability

The data characteristics of chemical fiber research reports impose multiple constraints on the traceability link.

Multi-source heterogeneous data sources and differentiated update rhythms require traceability information to clearly mark the data source type and data collection time, to avoid confusion between statistics and spot data from different time windows.

There are many specification parameters and physical indicators for segmented products. Traceability work must accurately extract the original text content of the corresponding fields, rather than broadly labeling the source as an industry research report.

Data sources from listed company announcements must be linked to specific announcement numbers and release times to ensure traceability is verifiable.

Document structures differ significantly across data sources. Unified extraction rules for traceability fields must be established to avoid missing or misplaced fields.

Daily updated spot quote data requires adding the collection time point to traceability information, to ensure the timeliness and accuracy of citations.

How to configure the settings

Configuration Item	Recommended Value	Rationale
`maxContext`	`8000–12000 characters`	Adapts to the 5000-10000 character length of individual chemical fiber research reports, and accommodates complete documents and traceability fields
`Max knowledge base citations`	`Top 3–5 entries`	Core information of chemical fiber research reports is concentrated in 3-5 highly relevant documents. Excessive references will increase context redundancy
`responseMaxTokens`	`2000–3000 characters`	Reserves sufficient space to output responses and complete traceability information, avoiding truncation of key content
`Similarity threshold`	`0.75–0.85`	Filters low-relevance search results for segmented chemical fiber product parameters, retaining highly matched research report content
`sourceDisplayMode`	`Full data source + release time`	Clearly displays the source and timeliness of traceability information to meet verifiability requirements
`parseChunkSize`	`1000–1500 characters`	Adapts to the long paragraph structure of chemical fiber research reports, accurately splits and locates traceability fields

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 specific analysis. It is recommended to test on your own samples before finalizing.

Three common configuration errors

Phenomenon: API call results forcibly include reference information and cannot be hidden. Cause: The sourceDisplayMode parameter is not configured correctly, and the full reference display mode is enabled by default.
Phenomenon: The number of reference documents returned by the search exceeds the preset range, or recalled documents do not match the chemical fiber category. Cause: The Max knowledge base citations and Similarity threshold parameters are not set reasonably, leading to redundant recalls or low-relevance results being included.
Phenomenon: Red error prompts appear in reference traceability information, and source content cannot be displayed normally. Cause: A reasonable duration for the parseFileTimeoutSeconds parameter is not configured, causing document parsing to time out and preventing normal extraction of traceability fields.

How to confirm the configuration is complete

Manually run a search for a single chemical fiber research report, check the display format of reference information in the returned results, and confirm it matches the requirements of the configured sourceDisplayMode.
Adjust the Max knowledge base citations parameter, and verify whether the number of reference documents returned by the search conforms to the modified setting logic.
Upload a single chemical fiber research report document, check the segmented content after parsing, and confirm that the parseChunkSize splitting logic adapts to the document structure.
Call the test API interface, check whether the returned response content contains complete traceability information with no truncation or missing content.

Question material comes from public community discussions. Configuration values are common starting points and should be measured against your own samples. Verified on 2026-09-14.
