What this category of data looks like
Data sources include daily financing report documents from textile manufacturing enterprises, loan receipt ledgers from cooperating financial institutions, and daily updated data from regional textile industry supply chain finance platforms. Updates occur daily. Each document covers all business entries for the current day. The core structure of the document is a structured table, with a small amount of accompanying text instructions. Fields include subject name, financing amount, received amount, financing period, and guarantee type. The unit for amount fields is ten thousand yuan. The unit for period fields is natural day or natural month.
What constraints do these characteristics impose on document parsing and chunking
The requirement to include all daily business entries results in a large number of entries per single document. Chunking must use business entries as the smallest unit to avoid context confusion caused by cross-entry merging. The high proportion of structured tables requires enabling table-enhanced parsing mode to preserve cell hierarchy and prevent misaligned table content. There is a potential risk of mixed use of field units, so unit verification rules must be configured to ensure amount fields consistently match the preset unit. The small amount of accompanying text instructions must be chunked in association with their linked table entries to avoid breaking business logic from independent splitting.
How to set the configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
PARSE_TABLE_ENABLE | Enabled | The document uses structured tables as its core carrier. Enabling this option preserves cell hierarchy and business association relationships |
Segment Length | 800–1000 characters | The average length of a single business entry plus associated supplementary instructions falls within the 600-900 character range. This range ensures each chunk contains a complete business unit |
PARSE_CHUNK_OVERLAP | 100–150 characters | Supplementary instructions with cross-chunk links exist between business entries. The overlap length preserves context connection information |
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | A single document contains dozens of business entries, and complex table parsing requires a longer processing duration |
ENABLE_PARSE_REFERENCE | Enabled | This function was added in version 4.9.0. Some documents include reference information for financing basis. Enabling this option fully extracts and binds the information to associated chunks |
The parameter values provided on this page are standard recommended starting points for defining configurations. Actual values are affected 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
- Symptom: After the parsing node runs, it returns "File parsing failed" or status code
408, and the corresponding file field in the knowledge base is empty. Cause:PARSE_FILE_TIMEOUT_SECONDSis not configured to a duration adapted to the scenario, causing parsing timeout for multi-entry documents. - Symptom: Table content in imported Word documents is misaligned, and chaotic data spanning multiple cells appears after chunking. Cause:
PARSE_TABLE_ENABLEis not enabled, and only the basic text parsing mode is used, which cannot recognize the hierarchical relationship of structured tables. - Symptom: The
referencesfield content in the document cannot be extracted after parsing, and the chunks do not include reference information. Cause: TheENABLE_PARSE_REFERENCEconfiguration item is not enabled, causing the system to ignore reference metadata in the document.
How to confirm configurations are correctly set
- Upload a single test textile manufacturing financing daily report document, check the table parsing results in the parsing log, and confirm that the cell hierarchy matches the original document.
- Access the document details page in the knowledge base, review the generated chunk list, and verify that each chunk contains complete single business information and associated supplementary content.
- Run a debug node, pass in the parsed document data, and check whether the reference field content in the document is extracted.
- Adjust the segment length configuration, compare the chunk splitting effects under different values, and confirm that the current value ensures the integrity of business logic.
