What the data for this category looks like
Data for shipping port financing daily reports comes from port operation management systems, vessel scheduling platforms, customs clearance data, and credit ledgers from cooperating financial institutions. Data is fully collected and validated for the previous day every early morning. Each daily report document uses a structured table as its core, with route notes and special operating condition explanations attached. Core fields include vessel voyage number, berth number, total cargo loaded/unloaded, financing application amount, approved quota, arrival time, departure time, and affiliated route. Total cargo loaded/unloaded is measured in tons. Monetary fields use Chinese Yuan as their unit. Time fields follow a standard format precise to the minute.
What constraints these characteristics impose on model integration and configuration
Daily updated data sources require the integration link to support scheduled incremental pulling, and adapt to batch data processing during fixed daily time periods. The structured document structure requires the model parsing module to prioritize identifying table field mappings, and avoid interference from unstructured content. Fields include standardized base fields and custom enumeration items such as routes and berths. Custom field mapping rules must be configured. The time field format requires the parsing module to retain records precise to the minute, to avoid format conversion errors. When batch data scale is large, concurrent processing parameters must be adjusted to avoid timeouts.
How to configure the parameters
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
incremental_sync_cron | 0 1 * * * | Aligns with the daily early morning update rhythm of the daily report, triggering synchronization after data collection and validation are complete |
parse_table_enable | enabled | The core content of the daily report is a structured table. Enabling this allows accurate field extraction, rather than only extracting text paragraphs |
custom_field_mapping | Configure vessel voyage number and berth number as custom mapping items | The data source has non-general enumeration fields, requiring manual alignment of knowledge base fields with data source formats |
timestamp_parse_pattern | yyyy-MM-dd HH:mm:ss | Matches the standard format of the data source's time fields, avoiding parsing failures |
batch_process_concurrent_limit | 3 | Adapts to the scale of single-batch daily report data, avoiding system timeouts caused by excessive concurrency |
rerank_top_k | top 5 entries | Shipping port financing related entries usually fall within the range of 4-6 entries, retaining sufficient candidates while reducing redundant calculations |
The parameter values provided on this page are general recommendations used as a starting point for configuration. Actual values are affected by material form, data volume and business rules. Each situation requires specific analysis. It is recommended to test on your own samples before finalizing settings.
Three common configuration mistakes
- Symptom: After configuring the re-ranking model, the order of knowledge base retrieval results does not change. Cause: The
rerank_top_kparameter is not set to a value greater than the number of recalled entries, so the re-ranking model does not receive enough candidate entries for sorting. - Symptom: The locally deployed parsing module cannot extract daily report table fields, but the online version works normally. Cause: The local deployment did not enable the
parse_table_enableconfiguration item, or did not install the supporting dependency packages for table parsing. - Symptom: An
ETIMEDOUTerror occurs after the scheduled synchronization task triggers. Cause: The time period set byincremental_sync_cronoverlaps with the data backup time period of the port system, causing the synchronization request to be rejected.
How to confirm the configuration is complete
- Manually trigger a data synchronization, check if there are field parsing failure errors in the synchronization log, and confirm that all fields configured in
custom_field_mappingare matched successfully. - Initiate a knowledge base retrieval, check if the order of retrieval results meets business expectations, and adjust the
rerank_top_kparameter until the sorting logic meets requirements. - Check the running records of the scheduled task, confirm that the daily synchronization task completes normally within the specified time period, with no timeout or interruption records.
- Verify that the parsed fields include all core business fields, and confirm that
timestamp_parse_patternmatches the time format of the data source.
