What the data for this category looks like
Data typically comes from national public resource trading platforms, natural resource trading systems, property right exchange systems, and state-owned asset supervision systems, with a daily update frequency. Daily processed documents include transfer announcements, trading notices, bid application forms, margin payment vouchers, transaction confirmation letters, listing result announcements, and property right transfer specifications. Most fields relate to ownership numbers, target valuations, margin amounts, transaction times, and similar details. Document structure varies slightly based on the type of trading target.
What constraints do these characteristics impose on the document parsing and chunking link
Documents updated at high frequency every day require parsing processes to have stability and speed. Format differences across multiple types of trading documents require strong parsing adaptability. The accuracy of core fields such as ownership information, margin amounts, and transaction confirmations directly affects business compliance, so the parsing link must accurately extract key information. Large documents such as transaction specifications have considerable length, which places high requirements on chunking rationality and completeness. This avoids truncating core transaction clauses that would cause errors in subsequent verification steps.
How to Set Configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Matches the average paragraph length of core trading documents for this category, avoiding truncation of key fields such as ownership information and margin amounts |
chunkSplitter | Segment by fixed character count plus line breaks | Adapts to fixed-format announcements and notice content in trading documents, reducing chunk breaks |
PARSE_FILE_TIMEOUT_SECONDS | 1200 seconds | Covers the parsing time of large property right transfer specifications, avoiding timeout errors |
customPdfParse | Enabled | Adapts to trading PDF documents with complex signatures and tables, improving parsing completeness |
UPLOAD_FILE_MAX_SIZE | 500 MB | Meets upload requirements for single large trading documents, adapting to batch document processing scenarios in property right exchanges |
Three Common Misconfigurations
- A
timeout of 360000ms exceedederror occurs when uploading trading documents larger than 10 MB. The cause is that thePARSE_FILE_TIMEOUT_SECONDSsetting does not match the parsing duration of large documents. - Some docx documents with special formatting have empty fields or missing content after parsing. The cause is that
customPdfParseis not enabled to adapt to non-standard docx layouts. - Imported question-and-answer pair knowledge bases return content that deviates from the original text. The cause is that
chunkSizeandchunkSplitterare not configured correctly, leading to incorrect chunking and truncation of question-and-answer pairs.
How to Confirm Configurations Are Applied Correctly
- Upload a single state-owned property right transfer specification PDF under 100 MB, check that parsing time meets business expectations and no timeout errors occur.
- Upload a docx document containing bid application forms and transaction confirmation letters, verify that extracted fields after parsing fully cover target information.
- Import a preset question-and-answer pair knowledge base, submit corresponding queries, confirm that returned content exactly matches the original text in the knowledge base.
- Complete the above tests under FastGPT v4.17.0 to ensure configurations take effect.
