What the data for this category looks like
Data sources for refining financial report analysis are public periodic reports of listed companies disclosed by domestic and overseas stock exchanges, and annual/semi-annual operating financial report documents officially released by enterprises. Update frequency follows regular disclosure regulations: quarterly reports are updated within 45 days after the end of each quarter, annual reports must be disclosed within four months following the year, and temporary operating data announcements are released as needed.
Document structure includes a general financial statement module and a special operating data module for the refining sector. The module contains fields such as current crude oil processing volume, refined oil output, and unit processing energy consumption. Crude oil processing volume is measured in tons, revenue in RMB yuan, and unit processing energy consumption in kilograms of standard coal per ton of crude oil.
What constraints do these characteristics impose on HTTP interfaces and external systems
The multi-source, multi-format nature of refining financial reports requires HTTP interfaces to support parsing and adaptation of multiple document formats such as PDF and HTML, while also being compatible with the differentiated layouts of disclosure documents from different stock exchanges.
The fixed-cycle and temporary trigger update schedule requires the interface to support both scheduled pull and manual trigger invocation modes, to meet the needs of obtaining regular financial reports and temporary operating announcements.
The refining sector has exclusive operating data fields, so the interface must provide custom field mapping configuration capabilities to convert special data in original documents into standardized structured fields.
When a single financial report document has a large file size, the interface must configure reasonable timeout thresholds and chunk processing logic to avoid interruptions due to single-request timeouts.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Refining financial report documents usually contain a large amount of special operating data, resulting in long parsing times. 600 seconds covers the parsing process for most documents |
UPLOAD_FILE_MAX_SIZE | 1000 MB | A single annual refining financial report PDF document can reach hundreds of MB in size. 1000 MB meets the upload requirements for conventional documents |
API_TRIGGER_MODE | Scheduled pull + manual trigger | Financial report data has two scenarios: fixed-cycle updates and temporary operating announcements. Dual modes cover full data acquisition needs |
CUSTOM_FIELD_MAPPING | Enabled | Refining financial reports contain exclusive operating data fields. Custom mapping rules are required to convert special fields in original documents into standardized output |
RETRY_MAX_TIMES | 3 retries | External data interfaces may experience temporary network fluctuations. 3 retries improve the success rate of data acquisition |
EMBEDDING_INPUT_MAX_LENGTH | 8192 characters | The special operating data text in refining financial reports is long. This adapts to the input length limit of large model embedding interfaces |
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 conduct practical tests on appropriate samples prior to finalizing settings.
Three Common Mistakes
- Symptom: A
{"error":{"code":"Invaliderror is returned when invoking a multimodal embedding interface. Cause: The embedding input length configuration was not adjusted for the long text content of refining financial reports, and the input text exceeded the maximum character limit supported by the model. - Symptom: No special operating data for the refining sector is extracted in the knowledge base after uploading a financial report document via the HTTP interface. Cause: Custom field mapping configuration was not enabled. The default parsing rules cannot recognize exclusive fields in financial reports, resulting in data loss.
- Symptom: Multiple consecutive request failures occur when pulling external financial report data sources on a scheduled basis. Cause: Reasonable retry times were not configured. A single network fluctuation caused the request to fail, and no automatic retry was performed, leading to data acquisition interruption.
How to Verify Proper Configuration
- Upload a refining financial report document, check whether the parsing result returned by the interface includes exclusive fields such as crude oil processing volume and unit processing energy consumption, to confirm that the custom field mapping configuration takes effect.
- Invoke the scheduled pull interface, verify that the latest financial report data can be automatically obtained according to the preset cycle, to confirm that the trigger mode configuration is correct.
- Simulate the upload of a large-volume document, check whether the interface completes parsing within the preset timeout period, to confirm that the timeout configuration is reasonable.
- Invoke the embedding interface to process long text fragments of refining financial reports, check whether normal embedding vectors are returned, to confirm that the input length configuration adapts to model requirements.
