What this category of data looks like
Data for this category originates from enterprise OA systems, organizational structure repositories, internal system documents, and user feedback. Routinely produced documents include process configuration sheets, approval node tables, form field descriptions, and change records. Most document structures consist of structured tables and step-by-step process descriptions. Fields cover approval node permissions, form validation rules, circulation time limit requirements, and similar items. There are no unified fixed units for these fields. Updates trigger when processes are modified, with an average of at least one update per month.
Constraints on document parsing and chunking
This category of documents mixes structured tables and unstructured process descriptions. The parsing link must accurately distinguish between table data and text paragraphs, and avoid splitting associated permission information across approval nodes. The frequent update schedule requires parsing processes to support incremental synchronization logic, reducing resource consumption from full repeated parsing. Multiple heterogeneous data sources require parsing to be compatible with different document layout formats, and avoid losing the hierarchical circulation relationship of approval nodes. Fields include strongly associated configuration items such as permissions and time limits. Chunking must retain contextual associations to ensure that complete configuration logic for a single node is fully retrievable during recall.
How to set configurations
| Configuration Parameter | Recommended Setting | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Adapts to the length of paragraphs and table blocks in process configuration sheets, avoiding splitting associated configuration information for approval nodes |
chunkSplitter | Paragraph + table recognition | Adapts to the mixed structured and unstructured nature of documents in this category, retaining contextual associations for node permissions |
customPdfParse | Enable enhanced parsing | Adapts to complex layouts of approval node tables, accurately extracting permission configuration and circulation rule fields within tables |
PARSE_FILE_TIMEOUT_SECONDS | 300–600 seconds | Addresses parsing time requirements for large change record documents, avoiding timeout interruptions of parsing tasks |
UPLOAD_FILE_MAX_SIZE | 100 MB | Adapts to batch-uploaded process configuration document volumes for enterprises, covering the size range of conventional office system documents |
chunkSettingMode | Manual configuration | Adjust chunking parameters for different document types (such as node tables, form descriptions) to optimize parsing accuracy |
Three common misconfigurations
- Symptom: Failure to properly extract approval node table content after enabling enhanced PDF parsing. Cause: Failed to correctly configure the
customPdfParseparameter to associate with the parsing engine, or the uploaded document size exceeds theUPLOAD_FILE_MAX_SIZElimit. - Symptom: Loss of column association relationships after table data is parsed and chunked. Cause: Did not set
chunkSplitterto table recognition mode. The default chunking logic breaks the binding relationship between table rows and columns. - Symptom: Timeout errors during parsing of process configuration sheets. Cause: Did not adjust
PARSE_FILE_TIMEOUT_SECONDSto a value adapted to the document volume, or the document contains nested approval rule modules that have not been parsed.
How to verify correct configuration
- Upload a typical approval node table document, review the parsed chunking results, and confirm that the association between table columns and rows has not been split.
- Submit batch change record documents, check the parsing task status information, and confirm that no timeout or file size limit errors occur.
- Enable table-related multi-vector support configuration in knowledge base settings, and verify that parsed table data can be accurately retrieved.
- Call the FastGPT v4.17.0 API to pull the document library interface, and confirm that the returned parsed chunked data includes complete approval node permission configuration fields.
