Citation Sources and Traceability for Oilfield Services

What data for this category looks like

Data for oilfield services engineering financing daily reports draws from three main sources: public reports from the China Petroleum Engineering and Construction Association, financing updates disclosed in quarterly financial filings of listed oilfield services enterprises, and third-party oil and gas industry financing databases. Updates occur once daily. The system releases financing project information from the prior business day on the same day. Most datasets use structured JSON format. Fields include project name, full financing party name, financing amount, currency, financing round, investor list, release date, and original data source link. Amount units are uniformly marked as ten thousand yuan or hundred million yuan.

Constraints for citation sources and traceability

The large number of clearly defined structured fields in this data requires precise matching of specified fields during citation traceability, to avoid retrieving irrelevant unstructured content. The daily incremental update data pattern requires configuring incremental synchronization tasks to only import newly added financing projects each day, preventing duplicate data from consuming storage space. Fields that include original data source links require attaching the corresponding link when generating citations, to meet industry compliance requirements. Mixed use of abbreviations and full names for oilfield enterprise names requires configuring entity normalization rules to standardize financing party name formats, ensuring consistent information during traceability.

Configuration Settings

Configuration Item	Recommended Value	Rationale
`maxContext`	`800–1200 characters`	Matches the average length of single entries in oilfield services engineering financing daily reports, avoiding truncation of key fields
`Recall Count`	`Top 3 entries`	Single financing daily report entry has small data volume. Excessive recall causes redundancy and increases computing costs
`Similarity Threshold`	`0.75–0.85`	Differentiates similar financing projects, avoiding confusion between financing of the same enterprise in different rounds
`UPLOAD_INCREMENTAL_SYNC`	`Enabled`	Adapts to the daily incremental update data source feature, reducing duplicate data processing
`PARSE_FILE_TIMEOUT_SECONDS`	`60 seconds`	Matches the parsing speed of structured JSON files, avoiding timeout interruptions
`SOURCE_LINK_REQUIRED`	`Mandatory Enabled`	Meets industry compliance requirements, ensuring original data source links are attached when generating citations

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

Three Common Mistakes

When calling the knowledge base, insufficient citation entries are returned, and the 400 Bad Request error prompt appears. Failing to adjust the default value of the Recall Count configuration item often results in the citation limit not meeting business needs.
Clicking a citation source link fails to open or download original data, and the interface shows 404 Not Found. This occurs when the SOURCE_LINK_REQUIRED configuration is not enabled, or imported data source links have expired.
After importing a structured JSON file, the knowledge base content is empty with no error prompt displayed. This happens when field mapping rules are not correctly configured, or incremental synchronization is not enabled, leading to old data not being properly identified.

How to Confirm Proper Configuration

Upload a test oilfield services engineering financing daily report JSON file, and verify that all preset fields are present in the knowledge base with no truncation or missing content.
Send a knowledge base recall request, and check that the number of returned citation entries matches the preset Recall Count configuration, and that similarity scores fall within the configured range.
Generate citation content, and confirm that every result includes the original data source link with no missing entries.
Wait for the next day’s incremental synchronization task to run, and check that the knowledge base has added the day’s financing project data with no duplicate imports.
