What This Category's Data Looks Like
Party building learning data in the bulk commodity trade sector mainly comes from internal party building office systems and business-integrated training platforms. Updates follow a schedule of monthly centralized updates and ad-hoc temporary policy updates. Document types include PDF official documents with letterheads, Word study manuals, and PPT training slides. Structures include fixed document headers, chapter main text, and business attachments. Fields include issuing authority, effective date, and topic classification. Units include "ten thousand tons" and "hundred million yuan" related to bulk commodity business, as well as "study hours" and "person-times" related to party building learning.
What Constraints Do These Characteristics Impose on Document Parsing and Chunking?
The fixed formats, mixed content, and fluctuating update rhythm of bulk commodity trade party building documents create multiple constraints for the parsing and chunking process. Documents with letterhead formats include redundant headers and footers, which must be filtered in advance to avoid interference from invalid content. Long documents mixing business terminology and party building content require balancing semantic coherence and term integrity to prevent chunking from splitting business logic. Multi-type mixed documents require adapting parsing rules for different formats such as PDF, Word, and PPT. Non-standard files uploaded temporarily require the parsing tool to maintain compatibility. Additionally, some documents contain sensitive classified fields, and sensitive content must be identified and filtered before chunking.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Bulk commodity party building documents mix business terminology and party building content. This range ensures complete single-chunk semantics and avoids splitting business logic across chunks |
chunkSplitter | Split by paragraph + title | Documents have fixed chapter structures. Splitting by title preserves document hierarchy, which facilitates matching topics during subsequent retrieval |
customPdfParse | Enable header and footer filtering | Letterhead document headers include redundant document numbers and institution information. Filtering improves the validity of parsed content |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Long documents such as annual party building work summaries take longer to parse. This duration prevents timeout interruptions |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Bulk commodity trade party building training slides often include high-definition images, resulting in large single-file sizes. This upper limit covers conventional upload requirements |
chunkSettingMode | Manual configuration | Adjusting chunking parameters is required for documents mixing business and party building content. Manual configuration adapts to scenario requirements |
Three Common Errors
- Phenomenon: PDF parsing returns error logs with no valid parsed content. Cause: The header and footer filtering configuration for
customPdfParseis not enabled. Complex formatting of letterhead documents triggers parsing engine exceptions. - Phenomenon: After uploading multiple party building documents, knowledge base retrieval results cannot distinguish sources. Cause: Metadata extraction logic is not configured, and identification information such as file name and upload time is not carried during chunking.
- Phenomenon: Expected content is not returned when searching for party building policy keywords. Cause:
chunkSplitteris not set to split by title, causing content from the same chapter to be split across multiple chunks, resulting in insufficient matching during retrieval.
How to Verify Proper Configuration
- Upload a single letterhead PDF document, and check whether the parsed result has removed fixed administrative content from headers and footers.
- Upload a party building training slide with multiple chapters, and check whether the chunking results match the document's title hierarchy.
- Upload multiple party building documents, and confirm that retrieval results can be associated with the corresponding original file names.
- Adjust the
chunkSizeparameter, and verify that single-chunk character counts fall within the preset range.
