What This Category of Data Looks Like
Oil and gas extraction financing daily report data comes from public financing announcements of domestic and overseas oil and gas extraction enterprises, stock exchange disclosure documents, and daily monitoring data from authoritative industry institutions. Updates run daily, covering all financing information for oil and gas extraction entities disclosed on the same day. Document structure includes fields such as full financing entity name, financing amount, financing method, financing completion time, fund usage, and disclosure source institution. Amount units are mostly ten thousand yuan RMB or million USD, with some cross-border financing projects noting the corresponding currency.
Constraints for Citation Sources and Traceability
Scattered data sources across domestic and overseas announcements require the traceability link to support cross-channel association matching, avoiding missed instances of the same financing event disclosed across platforms. The daily update rhythm requires the traceability system to support incremental indexing and incremental verification, preventing repeated recall of historical data. Fields such as fund usage and currency require precise binding of source documents to specific fields during traceability; only associating the main entity name cannot cover complete financing information. Delayed disclosure of some financing projects requires the traceability link to support marking of incompletely disclosed information, while retaining the full citation path of the original disclosure document.
Configuration Setup
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
rag_recall_top_k | Top 8-12 entries | Data sources for oil and gas extraction financing daily reports cover multiple channels including domestic and overseas announcements and industry monitoring. Recall enough relevant documents to cover complete financing information, while controlling redundant content |
parse_chunk_size | 800-1200 characters | Oil and gas industry financing announcements contain long disclosure paragraphs. This chunk length retains core information such as complete financing terms and fund usage, avoiding truncation of key traceability content |
incremental_index_enabled | Enabled | This category of daily reports uses daily updated data sources. Incremental indexing avoids repeated processing of historical files, improving traceability efficiency |
rag_reference_whitelist | Financing Entity, Financing Amount, Financing Time, Disclosure Source | The four listed items are the core traceability association fields for this category. Configuring the whitelist ensures only source documents matching the specified fields are bound, improving traceability accuracy |
rag_similarity_threshold | 0.75-0.85 | Oil and gas financing terminology is highly specialized. This threshold filters low-correlation non-financing announcements, while covering multiple financing entries for the same entity |
upload_file_max_size | 50 MB | Individual publicly disclosed oil and gas financing announcement files are mostly under 50 MB. This configuration adapts to conventional upload requirements |
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 the configuration.
Three Common Misconfigurations
- Phenomenon: API call results do not include traceability fields such as
source_filenameandpublish_time. Cause: Therag_return_source_infoconfiguration item is not enabled, or the whitelist of traceability fields to return is not specified in the configuration. - Phenomenon: Documents cited in generated results are not the highest matching oil and gas financing entries in the knowledge base. Cause: The configured
rag_similarity_thresholdis too low, or core fields such as "Financing Entity" and "Fund Usage" are not included in the similarity calculation weight, causing sorting logic to deviate from business requirements. - Phenomenon: Generated results contain fictional oil and gas extraction financing events not included in the knowledge base, with no prompt for unreasonable citations. Cause: The
rag_reference_validationconfiguration is not enabled, and cross-verification between large model generated content and knowledge base content is not performed, making it impossible to identify statements beyond the data source scope.
How to Confirm Proper Configuration
- Upload a single oil and gas extraction financing announcement document, check the chunked results after parsing, and confirm core fields are not truncated.
- Call the test API with oil and gas financing related queries, verify returned results include the configured traceability field information.
- Adjust the similarity threshold value, compare the number of recalled documents across different values, and confirm matching logic meets business requirements.
- Upload multiple oil and gas financing daily report documents from different dates, check that the incremental index only synchronizes newly added files with no repeated processing records.
