What this type of data looks like
Party building study data in the metal material processing field comes from official documents issued by the enterprise party committee office, monthly branch study minutes, industry party building themed policy interpretation documents, and party member study ledger forms. New study materials are added monthly, and policy documents are updated quarterly. Document formats include PDF study manuals, Word meeting records, and CSV party member study ledgers. Document structure is divided into title section, release information section, and main body section. The ledger table includes fields such as party member name, study date, study topic, and assessment score. Assessment score uses percentage as the unit, and study duration uses hours as the unit.
What constraints do these characteristics impose on the document parsing and chunking link
Mixed multi-format data sources require the parsing module to support batch processing of PDF, Word, and CSV files to prevent parsing failures for individual formats. The hierarchical structure of party building documents requires retaining the association between titles and main body during chunking, to ensure correct context can be linked during Q&A. Large PDF manuals and multi-page ledger tables consume significant parsing resources, so reasonable settings for parsing timeout and upload limit parameters are required. The multi-field nature of ledger tables requires complete extraction of all column contents during chunking, to avoid missing key party building study related information.
How to configure the settings
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Party building documents for metal material processing cover policy provisions, operation instructions and other content. 800–1200 characters can retain complete semantic units and avoid splitting that breaks context association |
chunkSplitter | Split by paragraph + title | Party building documents have clear chapter titles and paragraph hierarchy. Splitting according to this rule can retain the document structure, making it easier to link corresponding chapter content during subsequent Q&A |
UPLOAD_FILE_MAX_SIZE | 500 MB | Covers common file types such as large PDF manuals and multi-page ledger tables in metal material processing party building materials, meeting the upload needs of most business scenarios |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Provides sufficient time for format conversion and content extraction for large parsed files, avoiding parsing failures caused by timeout |
customPdfParse | Enabled | Metal material processing party building PDFs may include explanatory text next to industrial drawings. Custom parsing can optimize text extraction effects in such scenarios |
Three common errors
- A 413 error appears after uploading a file. The cause is that the
UPLOAD_FILE_MAX_SIZEparameter is not configured correctly, and the uploaded file exceeds the platform's allowed upload limit. - After importing a CSV format party member study ledger, only the first two columns of content are displayed. The cause is that the table full-column parsing mode is not enabled in the chunking configuration, and the default setting only extracts the first two column fields.
- Party building PDF documents embedded with industrial drawings fail to parse. The cause is that the external parser key corresponding to
customPdfParseis not set correctly, making it impossible to complete text extraction for custom formats.
How to verify the configuration is correct
- Upload a test metal material processing party building PDF manual, and check whether the parsed text content includes complete chapter titles and main body paragraphs.
- Upload a test party member study ledger CSV file, and check whether the parsing result extracts all column field contents.
- Adjust the
chunkSizeparameter, and check whether the chunk length in the chunking preview interface matches the set value range. - Check whether the external parser key corresponding to
customPdfParseis configured correctly, to ensure that PDF documents embedded with industrial drawings can be parsed normally.
