Citation Sources and Traceability for Plastics and Rubber

Data Profile for This Category

Data sources for this category include periodic reports of listed companies disclosed by the Shanghai and Shenzhen Stock Exchanges, and monthly industry operation data released by a national plastics industry association. Update frequency follows this schedule: annual reports are updated once per year, quarterly reports once per quarter, and industry data once per month. Documents mix structured tables and paragraph text. They include fields such as product output scale, revenue, raw material purchase volume, and production capacity scale. Most field units use physical or currency units such as tons, ten thousand yuan, cubic meters. Some industry classifications use standardized coding identifiers.

Constraints Imposed on Citation and Traceability

The data characteristics of this category create multiple constraints for the citation and traceability process.

There are significant format differences across data sources. Financial reports disclosed by stock exchanges are mostly structured PDF parsed content, while industry association data is mostly Excel tables. This requires adapting to different parsing and recall rules.

Differences in update frequency require targeted recall priority settings. Prioritize recalling content from the last 3 quarters for quarterly financial reports, and content from the last 12 months for monthly industry data.

There are potential differences in field units. Revenue and production volume disclosed by different entities may use ten thousand yuan or hundred million yuan, tons or kilograms as units. The original unit must be marked during traceability.

Standardized industry classification coding requires matching corresponding category identifiers during traceability to avoid cross-category data confusion.

Configuration Settings

Configuration Item	Recommended Value	Rationale
`PARSE_FILE_TIMEOUT_SECONDS`	`600 seconds`	PDF and Excel files for plastics and rubber financial reports usually contain large amounts of structured tables and long text, leading to long parsing times
`recall_top_k`	`Top 8 entries`	This category has a large number of financial report and industry data entries, need to cover core data on production, sales, and costs for major products
`similarity_threshold`	`0.75–0.85`	There are many industry-specific terms, need to ensure relevance between recalled content and queries, avoid mixing irrelevant data
`chunk_size`	`1000–1200 characters`	Financial report paragraphs and table content are lengthy. Too long segments will destroy contextual relevance, too short segments will lose key information
`return_citation`	`Enabled`	Financial report analysis requires clear marking of data sources to meet compliance and traceability requirements
`web_citation_enable`	`Enabled`	Can supplement traceability information for real-time market quotes, industry trends and other online data to improve the citation chain

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

Phenomenon: After calling the API to return a citation link, the corresponding source file cannot be downloaded directly, and a 404 Not Found status code is returned. Cause: The citation_download_auth parameter is not configured, or the access permission of the source file is not opened to the FastGPT parsing service.
Phenomenon: When exporting knowledge base data, only packaging by knowledge base dimension is supported, and export cannot be split by product category or data type. Cause: The knowledge_export_scope configuration item is not adjusted. The default setting only supports knowledge base-level export.
Phenomenon: Industry data obtained using online tools cannot display the citation source field in the response. Cause: The web_citation_enable configuration item is not enabled, or the traceability log storage path of the online tool is not configured.

How to Verify Correct Configuration

Upload a quarterly financial report PDF of a listed company in the plastics and rubber sector, check that the parsing process does not trigger timeout errors, and verify that the parsed text fully covers the core content of the financial report.
Submit a query about the revenue of a specific plastic product, check that the number of citation sources in the returned result matches the configured number of recalled entries, and that the source field includes identification information of the original document.
Call the API interface for obtaining citations, check that the returned result includes citation-related fields, and that the field content contains information such as document name and source path.
Attempt to export industry data from the knowledge base, confirm that the exported file can be sorted and organized by data type (if the corresponding configuration item has been adjusted).
