Citation Source and Traceability for Gas Industry Investment

What the data for this category looks like

Gas industry investment research data sources include upstream gas source quotes, city gas group pipeline operation reports, industry association monthly analysis reports, public utility regulatory policy documents, and real-time pipeline monitoring data. Update frequencies fall into four categories: real-time (pipeline pressure, gas supply volume), daily (gas source quotes), irregular (policy documents), and monthly (industry reports). Documents include structured reports (fields such as station ID, gas supply volume, pressure value), semi-structured analysis documents, and policy official documents. Some data is pulled in real time via API. Gas supply volume is measured in cubic meters, pressure in megapascals. Unique business identifiers such as station ID and gas source origin are included.

Constraints on citation source and traceability

Gas industry investment research data comes from multiple sources with varying update frequencies. Traceability information must match the collection timestamp of the corresponding data to avoid mixing data across cycles. Structured reports contain unique business fields such as station number and gas supply unit. These must be included in traceability metadata to support business cross-verification for investment research scenarios. Mixed recall of long-form analysis documents and real-time monitoring data requires traceability logic to distinguish source identifiers for different document types, ensuring accurate citation associations. Public utility data has compliance requirements. The traceability link must retain complete file storage paths and collection channel information to facilitate subsequent authenticity verification.

Configuration Settings

Configuration Item	Recommended Approach	Rationale
`retrieve_top_k`	Top 8-12 entries	Gas industry investment research data includes both structured reports and long-form analysis documents. Sufficient sources must be covered while avoiding redundancy that disrupts traceability logic
`source_metadata_fields`	`["file_name", "update_time", "station_code", "gas_unit"]`	Gas industry data contains unique business fields such as station code and gas volume unit. These must be included in traceability metadata to clarify source attributes
`PARSE_FILE_TIMEOUT_SECONDS`	300 seconds	Large pipeline planning PDF documents and monthly operation reports in the gas industry have lengthy content. Sufficient parsing time is required to fully extract traceability information
`api_return_source_detail`	Enable full traceability fields	Investment research scenarios require returning specific business parameters of the source, beyond basic file names, to support data cross-verification
`source_download_enabled`	Enable traceability file download	Gas industry data involves public utility compliance requirements. Full download of traceability files must be supported to complete authenticity verification

The parameter values provided on this page are common starting points for configuration setup. Actual values are affected by material format, data volume, and business rules. Specific issues require individual analysis. It is recommended to test with your own samples before finalizing settings.

Three Common Configuration Mistakes

Insufficient number of citation sources returned when calling the knowledge base, failing to cover all associated data. Cause: The retrieve_top_k configuration value is set too low, not matching the recall requirements for multi-source data in gas industry investment research.
In version 4.8.22, clicking a traceability link fails to download the corresponding file, with the interface prompting "resource does not exist". Cause: The source_download_enabled configuration is not enabled, or the storage path configuration for traceability files is incorrect.
When obtaining citation sources via API, the returned fields only include file names, and lack business fields such as station code and gas supply unit. Cause: Unique business fields are not configured in source_metadata_fields, and only basic metadata collection is enabled.

How to Verify Correct Configuration

Initiate a simulated investment research query, verify that the metadata of citation sources in the returned results includes unique business fields such as station code and gas volume unit.
Access the knowledge base configuration interface, confirm that source_download_enabled is enabled, and test that clicking a traceability link can normally download the corresponding file.
Call the API interface for obtaining citation sources, verify that the returned fields include all content in the configured source_metadata_fields list.
Adjust the retrieve_top_k value, verify that the number of returned citation sources changes with the configuration, matching the expected recall range.
