What the Data for This Category Looks Like
Daily documents for this category include inspection specifications, sampling plans, incoming material reports, supplier audit reports, exception liaison sheets, 8D reports, and concession acceptance approval forms. Data sources cover purchase orders, product drawings and specifications, supplier quality certificates, inspection equipment records, historical quality ledgers, and supplier portal data. Update frequency aligns with each incoming material batch, monthly or quarterly supplier evaluations, and ad-hoc special audits. Most document structures include fields such as batch numbers, sampling rules, nonconformity judgment criteria, and rectification requirements. Some drawing documents include technical parameters with units, such as dimensional tolerances and material grades.
Constraints Imposed on Document Parsing and Chunking
Documents in this category have diverse formats, including structured tables, free text, and drawing content with technical parameters. Parsing tools must support both structured data extraction and non-text content parsing. Data update frequency changes with incoming material batches and supplier evaluation cycles. Parsing tools must support distinguishing chunking ranges by document generation time or batch numbers. Some documents have continuous content across pages, such as complete 8D rectification workflows. Context continuity must be preserved for these sections. Associated fields including technical parameters with units and batch numbers must be accurately bound. Splitting associated information during chunking must be avoided, as this reduces matching accuracy for subsequent Q&A.
Configuration Settings
This guide applies to FastGPT v4.17.0. The following configuration scheme is adapted to this category:
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
customPdfParse | Enabled | This category includes a large number of PDF-format inspection specifications and supplier quality certificates. Enabling this option optimizes extraction of structured tables and technical parameters |
chunkSize | 800–1200 characters | This category’s documents include both short paragraphs with technical parameters and long texts such as complete rectification processes. This range balances context continuity and retrieval accuracy |
chunkSplitter | By paragraph + title | Documents in this category are mostly structured by inspection items and rectification steps. Chunking by title and paragraph preserves business logic integrity |
PARSE_FILE_TIMEOUT_SECONDS | 300–600 seconds | Parsing some large supplier audit reports or drawing documents takes a long time. This range avoids timeout failures |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Some supplier audit reports include multi-page attachments. This setting supports parsing large file uploads |
chunkSettingMode | Custom chunking | Documents in this category have large structural differences. Custom mode adapts to chunking needs for different document types |
Three Common Mistakes
- Issue: After enabling the enhanced PDF parsing option in knowledge base settings, parsing tasks always fail or return empty content. Cause: The locally deployed MinerU service port is not configured correctly, or FastGPT has no network connectivity to the MinerU service.
- Issue: After uploading structured table documents such as incoming material reports, the parsing result does not extract fields such as sampling plans and AQL values from the table. Cause: The
customPdfParseconfiguration item is not enabled correctly, or chunking settings do not adapt to structured data extraction logic. - Issue: When uploading multiple supplier audit reports in bulk, some tasks trigger timeout errors. Cause: The
PARSE_FILE_TIMEOUT_SECONDSconfiguration value is set too low, and does not adapt to parsing time for large documents.
How to Confirm Successful Configuration
- Upload a standard incoming material report PDF document, and check if the parsed text content includes core fields such as batch numbers, sampling rules, and nonconformity judgment criteria.
- Enable the enhanced PDF parsing function in knowledge base settings, call the FastGPT parsing interface, and verify that the returned structured data covers the table content in the document.
- Upload a supplier audit report larger than 500 MB, and confirm that the parsing task does not trigger a timeout prompt.
- Enter the keyword "sampling plan" to search the knowledge base, and check if the returned chunked content includes complete business information for the corresponding section.
The values provided here are common starting points, and should be evaluated against the samples used for the relevant deployment.
