What this category of data looks like
Party building learning data in the oilfield engineering services sector originates primarily from official documents issued by the internal party committee, monthly branch study minutes, post-level party building operation manuals, and on-site party building ledgers. The update rhythm is adjusted per superior party building deployments. Special study materials are updated on a monthly basis, while annual party building planning documents are updated quarterly. Supported document formats include PDF lecture courseware, Word study plans, and Excel attendance and party fee ledgers. Most documents include fixed fields such as issuing unit, effective date, and applicable construction teams. Some ledger documents contain multi-row and multi-column data items.
Constraints on document parsing and chunking
Mixed-format party building documents (PDF courseware, Word plans, Excel ledgers) require the parsing module to support multiple structured extraction workflows. Multi-row and multi-column associated data in Excel ledgers must retain cell correspondence to avoid data misalignment caused by simple paragraph-based splitting. Long documents such as annual party building summaries may contain tens of thousands of characters. Cross-chapter splitting must be avoided to preserve semantic integrity. Fixed fields such as applicable construction teams must be accurately identified to prevent splitting that separates fields from corresponding study content. High-frequency small entries in on-site ledger documents, such as daily study sign-ins, require small-grain chunking to meet precise matching needs during retrieval.
Configuration Settings
These configurations follow the official setup logic for FastGPT v4.17.0:
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Adapts to the length of single-chapter study content in oilfield party building documents, avoids overly fine or coarse splitting |
chunkSplitter | Split by title + paragraph | Matches the chapter-based structure of party building documents, preserves semantic integrity of study content |
PARSE_FILE_TIMEOUT_SECONDS | 300–600 seconds | Addresses parsing time for large PDF courseware or complex Excel ledgers, avoids premature timeout failures |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Supports uploading large documents such as annual party building summaries, adapts to full study material imports for oilfield engineering services |
customPdfParse | Enable structured extraction mode | For PDF lecture courseware, retains embedded tables and annotation information to improve parsing accuracy |
chunkSettingMode | Manual configuration mode | Adjusts chunking rules separately for different document formats, adapts to mixed-format characteristics of party building documents |
Three Common Mistakes
- After uploading an Excel party fee ledger, the parsing result only displays the header without content. This occurs because structured parsing mode for table documents is not enabled; default text-based splitting causes table data to be lost.
- After uploading a large PDF lecture courseware, the request fails after parsing takes more than 2 minutes. This occurs because the
PARSE_FILE_TIMEOUT_SECONDSconfiguration value is lower than the actual required parsing time, and insufficient time is reserved for processing complex format documents. - Post-chunking retrieval results include cross-chapter party building content that cannot match precise study topics. This occurs because
chunkSplitteris configured to split by character count, not by document title hierarchy, leading to broken semantic associations.
How to Verify Proper Configuration
- A typical Excel party building ledger is uploaded, and the parsing result is checked for retained cell row and column correspondence to confirm structured extraction is active.
- A PDF lecture courseware larger than 100MB is uploaded, and parsing completion is confirmed with no triggered timeout failure prompt.
chunkSizeis set to 800 characters, an annual party building summary document is parsed, and chunking results are checked for chapter-based splitting without cross-chapter content.- The
UPLOAD_FILE_MAX_SIZEconfiguration value is checked to confirm the single-document upload limit meets the maximum volume requirement for oilfield party building materials.
