What the data for this use case looks like
Documents for internal office and employee services at power generation groups mainly come from sources such as internal operation and maintenance systems, office OA platforms, and equipment management platforms. Document types include operation and maintenance repair reports, safety production rules and regulations, employee attendance reports, meeting minutes, power generation equipment technical manuals, and more. Update frequencies cover three categories: daily (such as daily operation and maintenance records), quarterly (such as safety system revisions), and annual (such as equipment archive filing).
Document structures include long text paragraphs, structured tables, and hierarchical title systems. Fields involve equipment numbers, maintenance durations, attendance counts, power generation capacities, and more. Units include hours, person-times, megawatts, and more.
What constraints these characteristics impose on the document parsing and chunking link
Operation and maintenance repair reports for power generation groups are usually lengthy and contain many technical terms. Chunking must avoid splitting coherent expressions that span technical terms. Otherwise, the accuracy of subsequent knowledge retrieval will be reduced.
Structured documents such as attendance reports and equipment ledgers must retain table formats and field correspondence. Otherwise, scenarios such as employee queries and data statistics cannot be supported.
Frequently updated operation and maintenance records have requirements for parsing efficiency. An overly long timeout will slow down office workflows. An overly short timeout will cause parsing failures for large documents.
Hierarchical rule documents must retain chapter structures to match employees' hierarchical query habits.
How to set the configurations
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Value Range | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Adapts to the content density of lengthy maintenance reports and technical manuals for power generation groups, avoiding splitting paragraphs with technical terms |
chunkSplitter | Split by paragraph + title | Retains the hierarchical structure of documents, adapting to rule documents and technical materials with chapters |
PARSE_FILE_TIMEOUT_SECONDS | 300–600 seconds | Matches the parsing time of large equipment operation and maintenance archives, avoiding parsing failures due to timeouts |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Supports the upload requirement of single large equipment operation and maintenance archives |
customPdfParse | Enabled | Retains table, formula, and embedded text formats in PDF documents, adapting to structured power generation technical documents |
chunkSettingMode | Manual configuration | Adjusts chunking rules for industry-specific technical terms, adapting to content characteristics of targeted scenarios |
Three common mistakes
- Parsed document content is missing, shown as unrendered tables or technical term text. The cause is not enabling
customPdfParse, which causes loss of non-plain text content during PDF parsing. - Technical terms are split across chunks, shown as the same term appearing in two separate chunked content blocks. The cause is using generic default chunking rules without adjusting the
chunkSplitterconfiguration for power generation industry terms. - Parsed text streams lose segment formatting, shown as a single unbroken block of text in front-end displays. The cause is not configuring chunking rules based on document structure, leading to missing reasonable line break markers during chunking.
How to confirm the configuration is correct
- Upload a maintenance report containing power generation equipment technical terms and tables, check if the parsed content retains complete table structures and unsplit technical terms.
- View the
PARSE_FILE_TIMEOUT_SECONDSconfiguration item, confirm the set duration matches the estimated parsing time of the target document to avoid timeout issues. - Test chunked text fragments, confirm no cross-paragraph technical terms have been split.
- Upload a test file at the maximum allowed size, confirm upload and parsing processes complete normally, verifying that the
UPLOAD_FILE_MAX_SIZEconfiguration takes effect.
