Document Parsing and Chunking for Joint-Stock Bank Intelligent Due Diligence Reports

Data sources for joint-stock bank intelligent due diligence reports include internal credit approval documents, external regulatory submission files

What the Data for This Category Looks Like

Data sources for joint-stock bank intelligent due diligence reports include internal credit approval documents, external regulatory submission files, public corporate financial reports, and peer due diligence materials. Update rhythm aligns with credit project cycles: generated by operating staff when the project launches, and updated on demand during the credit ongoing period. Most documents are in PDF or DOCX format, with a fixed chapter structure: credit subject basic information, financial data tables, risk control indicators, guarantee status, and industry analysis. Most fields have clear units, such as revenue and asset size marked with ten thousand yuan, hundred million yuan, etc. There are also many nested attachments.

How These Characteristics Impact Document Parsing and Chunking

Large volumes of structured tables require the parsing process to retain the association between cells and their context, preventing financial fields from being separated from their corresponding explanatory text after splitting. Fixed chapter structures nested in long documents require chunking to split at chapter boundaries, ensuring that retrieval can accurately locate the corresponding business module. Financial data with clear units requires the parsing process to retain unit suffixes, avoiding ambiguity between identical fields with different units during matching. Scenarios where multiple attachments are uploaded in a package require the parsing process to support batch associated parsing, preventing disconnection between attachment content and the main document.

Configuration Settings

Configuration ItemRecommended SettingRationale
PARSE_TABLE_ENABLEEnabledThe due diligence report contains a large number of structured financial tables, and the association between cells and their context must be retained
CHUNK_MAX_LENGTH1000–1500 charactersThe content of individual chapters of joint-stock bank due diligence reports is lengthy, balancing context association and retrieval accuracy
UPLOAD_FILE_MAX_SIZE500 MBAdapts to scenarios where a single due diligence report contains multiple attachments, meeting the needs of uploading project-level document packages
PARSE_FILE_TIMEOUT_SECONDS900 secondsLong documents and multi-attachment parsing require sufficient processing time to avoid mid-parsing timeout interruptions
INCLUDE_CHUNK_HEADINGEnabledChapter titles of due diligence reports can assist retrieval in locating specific modules, improving matching accuracy
TABLE_PARSE_KEEP_UNITEnabledRetains unit suffixes in financial data tables, avoiding field ambiguity during retrieval

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

Three Common Misconfigurations

  • Phenomenon: A PDF file uploaded via the API returns a parsing failure with status code 413; Cause: The UPLOAD_FILE_MAX_SIZE configuration was not adjusted, and the document size exceeds the platform's default limit.
  • Phenomenon: RAG retrieval results do not include document chapter title information; Cause: The INCLUDE_CHUNK_HEADING configuration was not enabled, and prefixed chapter content was not associated during chunking.
  • Phenomenon: When using Vllm 0.10-deployed Qwen3-14B to call the parsing component, structured table fields cannot be extracted; Cause: The structured output format of the parsing component does not adapt to the response rules of this model, resulting in failed field extraction.
  • Phenomenon: Uploaded DOCX documents have financial data unit suffixes missing from parsing results; Cause: The TABLE_PARSE_KEEP_UNIT configuration was not enabled, and unit information in table cells was not retained during parsing.

How to Confirm Proper Configuration

  • Upload a sample joint-stock bank due diligence report containing structured financial tables, and check if the parsing result retains the complete table structure and cell content.
  • Initiate a RAG retrieval test to verify that the retrieval results include the chapter title information of the corresponding document.
  • Check the parsing task logs to confirm that the parsing time does not exceed the threshold set by the PARSE_FILE_TIMEOUT_SECONDS configuration.
  • Upload a test document exceeding the platform's default upload limit, and verify whether the UPLOAD_FILE_MAX_SIZE configuration takes effect.
