Knowledge Base Retrieval and Recall for Rural Commercial Bank Financial Report Analysis

Data sources for rural commercial bank financial reports include public disclosure documents from local banking and insurance regulatory bureaus

Data Characteristics of This Category

Data sources for rural commercial bank financial reports include public disclosure documents from local banking and insurance regulatory bureaus, official annual reports and quarterly operation briefs of institutions. Annual reports are disclosed by April 30 of the following year. Semi-annual reports are disclosed by August 31 of the same year. Quarterly operation data is updated within 15 days after the quarter ends. Document structure includes balance sheet, income statement, cash flow statement, regulatory operation indicator statistical table, and special statistical table for agriculture-related and micro and small enterprise loans. Fields include total loan balance, agriculture-related loan balance, core tier 1 capital net amount, provision balance, and others. Units are uniformly ten thousand yuan or hundred million yuan.

Constraints Imposed on Knowledge Base Retrieval and Recall

Multi-source data formats for rural commercial bank financial reports vary. Metadata alignment must be completed before retrieval to avoid naming or format discrepancies for the same field across different sources. Layered update schedules require setting incremental update tasks per cycle to reduce resource consumption from repeated full data processing. Documents include general reports and special statistical tables with many subdivided fields. Exclusive retrieval weights must be configured for special fields. Units primarily use ten thousand yuan and hundred million yuan. Unified conversion rules must be set to avoid matching deviations. Special loan data is a core retrieval requirement. Recall scope must be limited to specified fields to reduce irrelevant result interference.

Configuration Settings

Configuration ItemRecommended ValueRationale
Recall countTop 8-12 entriesSpecial fields for rural commercial bank financial reports are concentrated. A small number of precise entries can cover analysis needs. Excessive entries will increase context load
Similarity threshold0.72-0.80Financial report terminology is highly professional. A high matching degree is required to avoid irrelevant document recall, while retaining tolerance for terminology variants
PARSE_FILE_TIMEOUT_SECONDS120 secondsRural commercial bank financial reports contain multiple structured tables. Parsing takes a long time. This setting avoids parsing failure due to timeout
Chunk size800-1000 charactersFinancial report tables have compact content. Too long segments will lose context association. Too short segments will destroy the logical integrity of tables
Incremental Update Scheduling RuleTrigger daily updates quarterly, trigger full updates semi-annually and annuallyMatches the layered update schedule of rural commercial bank financial reports, reducing resource consumption from repeated full data processing
FIELD_WEIGHT_MAPSet the weight of agriculture-related loan balance and micro and small enterprise loan balance to 1.5, set the weight of other fields to 1.0Special loan data is the core retrieval requirement for rural commercial bank financial report analysis. This setting increases the recall priority of corresponding fields

Three Common Mistakes

  • Phenomenon: Calling knowledge base retrieval in a conversation returns empty results, but retrieval works normally in the knowledge base backend test. Cause: Knowledge base permission binding for the conversation scenario is not configured, or the token threshold for conversation context is too low, causing truncation of retrieval request parameters.
  • Phenomenon: Parsing fails after uploading rural commercial bank financial report files, and the backend log returns 413 Request Entity Too Large error. Cause: The UPLOAD_FILE_MAX_SIZE configuration item is not adjusted. The size of a single annual report file for rural commercial banks usually exceeds the default limit.
  • Phenomenon: Parsed document fields have mixed units, with some data shown in yuan instead of the preset ten thousand yuan unit. Cause: The UNIT_AUTO_CONVERT switch is not enabled, or unified unit conversion rules are not configured.

How to Verify Successful Configuration

  • Upload a single rural commercial bank annual financial report file. Check the parsed field list to confirm that preset fields including agriculture-related loan balance and core tier 1 capital net amount are correctly extracted.
  • Enter a retrieval keyword that includes "agriculture-related loan". Initiate retrieval on both the knowledge base backend test page and the conversation interface. Compare the number and content of recalled documents to confirm that the configured weight rules take effect.
  • View the scheduling logs of incremental update tasks. Confirm that daily updates are triggered quarterly, and full updates are triggered semi-annually and annually according to the corresponding cycles, with no abnormal interruption records.
  • Adjust the terminology variants of retrieval keywords, such as replacing "micro and small enterprise loans" with "small and micro enterprise loans". Confirm that the matching degree of returned results meets the preset similarity threshold requirements.
