What this category of data looks like
Telecommunications engineering construction policy and regulatory basis data comes from official announcements, industry standard documents, engineering construction quota documents, etc., issued by the Ministry of Industry and Information Technology, Ministry of Housing and Urban-Rural Development, and local industry regulatory authorities. Updates are synchronized when new policies are released, standards are revised, or annual updates occur. Supported document formats include editable Word, PDF, and some scanned PDFs. Most documents follow a structure that includes document numbers, issuing entities, effective dates, chapters and clauses, attached data tables, and more. Fields covered include policy numbers, applicable scope, specific implementation clauses, engineering parameter indicators, and more. Units used include ten thousand yuan, kilometers, square meters, number of ports, and others.
Constraints imposed on the document parsing and chunking link
Dispersed data sources lead to diverse document formats, including both editable text and scanned PDFs. This requires the parsing process to support multi-format adaptation. Policy documents have strict clause hierarchies. Chunking must retain associated information such as document numbers and chapter numbers to avoid splitting independent clauses. Engineering parameter tables in attachments must fully preserve field associations, and cell content cannot be split. Update frequencies are inconsistent. The system must support batch re-parsing of historical documents, and distinguish between policy versions to avoid confusion.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Policy document clauses are mostly short paragraphs, balancing semantic completeness and indexing density |
chunkSplitter | Chunk by title + paragraph | Matches the hierarchical structure of policy documents, avoiding splitting independent clauses |
customPdfParse | Enable OCR mode | Process some scanned official policy PDFs to fully extract printed text |
PARSE_FILE_TIMEOUT_SECONDS | 300–600 seconds | Large policy compilation files take longer to parse, preventing mid-parsing timeout interruptions |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Adapt to uploads of large industry standard documents containing multiple attachments |
chunkSettingMode | Manual configuration | Adjust chunking parameters for different types of policy documents |
Three Common Misconfigurations
Reference only; verify against the target FastGPT release and deployment documentation.
- Phenomenon: When connecting the minerU document parsing tool, no parsing process is triggered after uploading a file. Cause: The minerU parsing plugin was not enabled in the system plugin management, and the correct API access key and callback address were not configured.
- Phenomenon: Uploaded policy documents are split into scattered character blocks, and clause hierarchies cannot be retained. Cause: The
chunkSplittersetting for chunking by title + paragraph was not enabled, and default character-based chunking was used, which destroys clause associations.
How to Verify Correct Configuration
- Upload a telecommunications engineering policy PDF containing scanned pages, check if the parsing result fully extracts the scanned text to confirm that the
customPdfParseconfiguration takes effect. - Adjust
chunkSizeto 800 characters and 1200 characters, upload the same policy document separately, compare the chunking results to confirm that the chunking length meets expectations. - Check the parsing logs in the system backend to confirm that no timeout error was triggered for the uploaded large policy compilation file, and that the
PARSE_FILE_TIMEOUT_SECONDSsetting is reasonable. - Check the running status of the minerU parsing plugin on the plugin management page, confirm that the plugin has been properly connected, and that the parsing process can be triggered after uploading a test file.
