What the Data for This Category Looks Like
This category of data originates from the unified budget management system, centralized treasury payment system, accounting system, and asset management system. The update frequency is once per year. Daily documents include department final account statements, balance sheets, income and expenditure final account statements, final account explanations, and government financial reports. Most documents are a mix of structured tables and explanatory text. Fields include revenue and expenditure details, assets and liabilities items, budget execution difference explanations, and more. Units are mostly yuan and ten thousand yuan. Some documents contain multi-level nested sub-tables.
What Constraints Do These Characteristics Impose on the "Document Parsing and Chunking" Link
Documents in this category are mostly mixed batches of structured tables and explanatory text generated annually. They contain nested sub-tables and fixed fields. When parsing, the table structure and field correspondence must be retained. Avoid splitting key table rows or budget execution difference explanation paragraphs across pages. Document formats exported from different systems have minor differences, so multiple import formats must be supported. The number of documents updated in annual batches is large, so performance requirements for batch parsing must be met. Also avoid chunking failures caused by overly long single documents. The party building learning Q&A scenario requires ensuring the integrity of data fragments, avoiding missing key policies or data explanations due to chunking errors.
Configuration Settings
The following configurations apply to FastGPT v4.17.0.
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Adapts to the mixed length of table rows and explanatory text in documents of this category, avoiding splitting key data segments |
chunkSplitter | Split by paragraph + table boundary | Retains the integrity of final account explanations and report tables, avoiding damage to field associations during chunking |
customPdfParse | Enabled | Adapts to PDF documents with nested sub-tables, retaining original typesetting and field structure |
UPLOAD_FILE_MAX_SIZE | 500 MB | Compatible with the size of single final account documents exported in annual batches, avoiding upload failures |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Addresses parsing time consumption for complex nested tables, avoiding mid-process timeout interruptions |
chunkSettingMode | Custom mode | Adjusts chunking rules for structured documents of this category, adapting to fixed fields and nested structures |
Three Common Mistakes
- Parsing succeeds after uploading a document, but the table content is not included in the large model output. Cause: The
customPdfParseconfiguration is not enabled, causing the structure of nested tables to be flattened and split, losing field association information. - A "only supports .txt, .m" type error is returned during parsing. Cause: The uploaded Word or Excel document was not processed by the built-in parser, or the file upload size limit was not configured correctly, causing pre-parsing verification to fail.
- Chunking results do not meet expectations after custom chunk length is set. Cause: The
chunkSplitterrule was not adjusted based on the table structure of documents in this category; only modifyingchunkSizecauses key table rows to be split across chunks.
How to Confirm the Configuration Is Correct
- Upload a single typical final account report document, view the parsed text preview, and confirm that the table structure matches the original document, with no key rows split across chunks.
- Upload batch annual documents, check the status logs of parsing tasks, and confirm that no timeout failure records appear.
- Test Q&A calls related to party building learning, and confirm that the returned results contain complete fragments of final account explanations and report data, with no missing field content.
- View the backend upload logs, and confirm that documents of normal size are not blocked by the
UPLOAD_FILE_MAX_SIZEconfiguration.
