What Data Looks Like for This Category
Data for this category mainly comes from the "One Task" special zone of the National Government Service Platform, local integrated government service platforms, electronic certificate repositories, and approval systems of various departments. Updates are performed daily. Commonly processed documents include joint handling item lists, one-time notice sheets, joint handling application forms, material circulation forms, parallel approval opinions, and completion receipts. Most document structures include fields such as cross-department item associations, material reuse rules, and processing node requirements. There is no unified fixed format, and some documents embed department-specific approval fields and circulation node identifiers.
Constraints Imposed on the Document Parsing and Chunking Link
Daily updated document volume fluctuates, so the parsing link must support multiple file types to adapt to multi-source and heterogeneous government document formats. Core fields such as cross-department item associations and material reuse rules require retaining context associations during chunking to avoid losing pre- and post-item logic after splitting. Some documents embed department-specific approval identifiers and circulation nodes, so accidental splitting that causes field breaks must be avoided. Completion receipts and parallel approval opinions are mostly short texts. A balance must be struck between chunk length and information integrity to prevent key processing node information from being split apart.
Configuration Settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Adapts to the cross-department association structure of joint handling business documents, retains complete item nodes while avoiding redundancy |
chunkSplitter | Semantic chunking, prioritize matching joint handling item logic | Avoids splitting that breaks the association relationship of cross-department processes |
customPdfParse | Enabled | Retains tables and department-specific identifiers in joint handling application forms and approval opinions, preventing loss during parsing |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Adapts to batch joint handling document packages exported from local government platforms, preventing upload failures |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Handles complex parsing processes for multi-department associated documents, avoiding timeout interruptions |
chunkSettingMode | Manual configuration | Adjust chunking parameters for different types of joint handling documents (such as lists, application forms) |
Three Common Mistakes
- Phenomenon: When uploading a joint handling PDF document containing department approval tables, the interface prompts a request error, or the parsed document content lacks tables and department identifier fields. Cause: The
customPdfParseconfiguration is not enabled, so it cannot adapt to the exclusive table format and department identifiers in government documents. - Phenomenon: After parsing a joint handling application form, the complete content of cross-department material reuse rules is split into multiple chunks. Cause: The
chunkSizevalue is too small, causing complete material association logic to be split apart. - Phenomenon: When uploading a batch joint handling document package, the parsing process is interrupted halfway and returns a timeout prompt. Cause: The
PARSE_FILE_TIMEOUT_SECONDSvalue is lower than the actual required parsing duration, and does not adapt to the complex structure of multi-department documents.
How to Verify Proper Configuration
- Upload a single standard joint handling item list PDF, check whether the parsed chunk content includes complete cross-department association instructions, and adjust
chunkSizeuntil the chunks cover complete logical nodes. - Upload a joint handling application form containing tables, confirm that the parsing result retains table fields and department identifier content, and verify that the
customPdfParseconfiguration is active. - Upload a batch joint handling document package, check that the upload and parsing processes are not interrupted, and confirm that the
UPLOAD_FILE_MAX_SIZEandPARSE_FILE_TIMEOUT_SECONDSconfigurations adapt to the current document scale. - Import a one-time notice sheet document, check whether the chunks retain complete processing requirements and material lists, and adjust the
chunkSplitterlogic to match the document structure.
