What Data Falls Under This Category
Data for this category primarily comes from project document libraries, configuration lists, meeting minutes, and test reports. Updates occur at the end of each project phase or upon overall project completion. Commonly processed documents include completion documents, configuration manuals, training records, and acceptance certificates. Document structures include structured fields such as project numbers and acceptance nodes, as well as unstructured business descriptions. Some documents include standardized signature pages. Data is maintained daily by project managers, implementation consultants, and customer archive administrators. The size of individual documents varies with project scale, and the core content revolves around project delivery evidence and subsequent operation and maintenance support.
What Constraints Do These Characteristics Impose on Document Parsing and Chunking
The document characteristics of this category impose multiple constraints on parsing and chunking. The task attribute of batch offline processing requires parsing tools to support batch upload and batch chunking configuration. Document types include structured lists, unstructured minutes, and acceptance certificates with signatures. Targeted chunking rules must be configured to avoid splitting that breaks the association between structured fields or the integrity of signature pages. Historically archived documents may have inconsistent versions. Chunking must retain the context of version identifiers to avoid confusion between different versions of content during retrieval. The size of individual documents varies with project scale. Parsing must adapt to documents of different lengths to avoid overloaded or overly fragmented single chunks that affect retrieval performance.
How to Configure Settings
For FastGPT v4.17.0, the following configuration items can be adapted to the document parsing needs of this category:
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Adapts to the length of business paragraphs in documents of this category, avoiding overloaded or overly fragmented single chunks |
chunkSplitter | Split by paragraph + title | Matches the structured chapter structure of documents in this category, retaining contextual associations |
customPdfParse | Enabled | Adapts to complex PDF documents such as acceptance certificates with signatures, improving parsing integrity |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Addresses the parsing time requirements for large completion documents or batch documents |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Adapts to the maximum individual size of project archive documents |
chunkSettingMode | Manual configuration | Adjusts chunking rules for different document types to meet the accuracy requirements of compliance review |
Three Common Configuration Mistakes
- Phenomenon: Timeout errors are triggered when parsing large PDF documents, and logs show request execution time exceeds 60000ms. Cause: The
PARSE_FILE_TIMEOUT_SECONDSparameter is not adjusted, and the default timeout duration is insufficient for parsing tasks for large completion documents. - Phenomenon: The number of entries returned when retrieving Excel data is less than the source file. For example, results filtered by overseas usage locations are incomplete. Cause: Complete row associations for structured tables are not retained during chunking, or parsing rules for table data are not configured, resulting in partial fields being truncated or omitted.
- Phenomenon: After uploading documents in batch, the signature pages of some acceptance certificates are parsed as empty or have distorted formatting. Cause: The
customPdfParseconfiguration is not enabled, and the default PDF parsing cannot adapt to the archive document format with embedded signatures.
How to Verify Correct Configuration
- A single typical document such as an acceptance certificate is uploaded, and the parsed chunked content is reviewed to confirm that structured fields and signature pages are not incorrectly split.
- The
chunkSizeparameter is adjusted, and chunking results across different values are compared to select a configuration that matches the length of business paragraphs. - A large completion document is uploaded, parsing time is monitored, and the
PARSE_FILE_TIMEOUT_SECONDSparameter setting is confirmed to meet actual time requirements. - A configuration manual containing tables is uploaded, and complete table data fields are verified to be returned during retrieval.
