What the data for this category looks like
This data originates from Party Building learning archives of state-owned and state-controlled enterprises in the refinery and chemical sector. It includes Party Building study guidelines issued by superior Party committees, internal enterprise Three Meetings and One Lecture records, Theme Party Day study materials, and some Party Building presentation documents tied to production safety themes. Superior documents are updated quarterly, while internal team study materials are updated monthly. Most documents are in Word or PDF format with multi-level headings. Some contain embedded study Q&A questions and images. Fields include document number, issuing entity, study theme, and applicable workshop scope, with units covering workshops, Party branches, and Party committees.
What constraints these characteristics impose on the document parsing and chunking link
When chunking multi-level nested heading documents, retain title hierarchy associations to avoid splitting study content from the same theme. Some documents contain embedded study Q&A questions and images. Identify these embedded elements during parsing, ensure chunking does not interrupt Q&A logic, and handle associated image binding. For documents with applicable workshop or section scope, retain contextual context during chunking to avoid splitting study content for the same applicable scenario into unrelated chunks. Monthly updated internal materials and quarterly updated superior documents require the parsing process to support stable batch processing, to avoid parsing failures caused by differences in document formats.
How to set configurations
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Refinery and chemical Party Building documents often combine production terminology. Chunks that are too long will cause redundant context, while chunks that are too short will split the Party Building logic related to production |
chunkSplitter | Split by heading + paragraph | Documents have multi-level headings. Splitting by headings preserves theme integrity and adapts to the hierarchical structure of Party Building study materials |
customPdfParse | Enabled | Some documents have embedded study Q&A and images. Enabling custom PDF parsing preserves the associated relationships of embedded elements and avoids content loss |
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | A single Party Building document can be up to 30 pages. Sufficient parsing time must be reserved to avoid timeout failures |
chunkSettingMode | Manual configuration | The format of refinery and chemical Party Building documents varies widely. Manual configuration allows flexible adjustment of chunking rules to adapt to different types of study materials |
Three common mistakes
- Phenomenon: A PDF document is uploaded and parsing succeeds, but embedded study Q&A or image content does not appear in knowledge base search results. Cause: The
customPdfParseconfiguration is not enabled. The default parsing logic does not retain the associated binding of embedded elements. - Phenomenon: The number of search results after chunking is far lower than expected, and content is abnormally truncated. Cause: The
chunkSizevalue is too small. The complete theme of a single Party Building document is split into multiple unrelated small chunks, making it impossible to match the complete study logic during search. - Phenomenon: When multiple Party Building documents are uploaded in batch, some documents fail parsing and return a timeout error. Cause: The
PARSE_FILE_TIMEOUT_SECONDSvalue is lower than the actual parsing time required by the document, and sufficient processing duration is not reserved.
How to confirm the configuration is correct
- Upload a Party Building document with multi-level headings and embedded Q&A, check the parsed text structure to confirm that the heading hierarchy matches the original document.
- Enter Party Building study theme keywords in a knowledge base search test, check the chunk integrity of returned results to confirm that no content truncation or theme splitting has occurred.
- Upload the longest single Party Building document, wait for parsing to complete, confirm that no timeout error is triggered, and verify that the timeout configuration value adapts to the current document size.
- Upload 3 to 5 different types of Party Building study materials in batch, check that all documents have a successful parsing status, and confirm that the configuration adapts to multi-format documents.
