What this category’s data looks like

This data primarily supports bidding risk control and compliance review for finance, insurance, and wealth management sectors. It originates from government procurement bidding announcement documents and official notices from industry bidding platforms. Updates follow the bid opening and qualification review progress of corresponding bidding projects. A single document may contain a summary of bid rejection items for all sections of one project, or a batch list of multiple projects. Some documents include original scanned attachments for qualification pre-examination. Fields include project number, section name, bid rejection reason, involved bidding entities, bid quotation, qualification review items, and more. Most bid quotation fields use Chinese Yuan (RMB) or ten thousand Yuan as units.

How these characteristics impose constraints on document parsing and chunking

The data format for this category is inconsistent. It includes both structured table-style batch bid rejection lists and public announcements mixing text and attachments. A single document may contain dozens of bid rejection item entries. Entries are linked via fields such as project number and section name. When splitting content, the binding relationship between fields and their corresponding bid rejection reasons must be preserved to avoid losing contextual links after splitting. There is no fixed upper limit for the number of historical documents uploaded in batches. The system must support parsing large files in chunks, and handle structured data extraction from scanned attachments processed via OCR to ensure accurate field alignment. Some bid rejection reasons contain professional bidding terminology. Chunk length must fit the semantic completeness of these terms to avoid over-splitting.

Configuration Settings

Configuration ItemRecommended ValueRationale
PARSE_FILE_TIMEOUT_SECONDS600-900 secondsBid rejection item documents may include multiple attachments and have large individual file sizes. Sufficient parsing time must be reserved. For open-source versions 4.9.2 and above, resumable upload logic must be additionally adapted
maxChunkSize800-1200 charactersProfessional terminology and linked fields for bid rejection items require complete semantics to avoid breaking the binding relationship between project details and bid rejection reasons during splitting
chunkOverlap100-150 charactersPreserve contextual links between fields and bid rejection reasons, preventing cross-chunk breaks that would prevent complete information matching during retrieval
UPLOAD_FILE_MAX_SIZE500-1000 MBBatch bid rejection item lists may include a large number of scanned attachments. Large file uploads must be supported to avoid interception due to exceeding file size limits
PARSE_OCR_ENABLEEnabledSome bid rejection item documents include qualification review scanned documents. Text content from these must be extracted to fully parse bid rejection item information
rerankTopNTop 3-5 resultsBid rejection item retrieval requires precise matching of project numbers and bid rejection reasons. Too many results will interfere with positioning for the business scenario

The parameter values provided on this page are common starting points for configuration setup. Actual values are affected by material format, data volume, and business rules. Specific issues require case-by-case analysis. It is recommended to test with your own samples before finalizing settings.

Three Common Configuration Mistakes

  • Symptom: Batch upload of bid rejection item documents is interrupted mid-process, and parsing progress cannot be resumed after restarting the service. Cause: PARSE_FILE_TIMEOUT_SECONDS is not configured to a duration suitable for large files, and resumable parsing is not enabled. Parsing status is not retained after timeout.
  • Symptom: After parsing a bid rejection item document, the model’s response does not reference the bid rejection item data from the document. Cause: maxChunkSize is set too small. Splitting breaks the semantic binding between project numbers, section names, and bid rejection reasons, preventing complete linked information from being retrieved during searches.
  • Symptom: After uploading a bid rejection item document in scanned format, no parsing logs or error prompts appear in the backend. Cause: PARSE_OCR_ENABLE is not enabled. The parsing module cannot extract text content from the scanned document, so it skips the parsing process directly.

How to Verify Correct Configuration Setup

  • Upload a single test document containing bid rejection items for multiple sections. Check if parsed fragments retain the binding relationship between project numbers and their corresponding bid rejection reasons. Adjust maxChunkSize until the linked information is complete.
  • Upload a batch of historical bid rejection item documents. Verify that the upload progress completes without mid-process interruptions, and confirm that PARSE_FILE_TIMEOUT_SECONDS and resumable upload configurations are active.
  • Upload a bid rejection item document in scanned format. Check if the parsed result includes text content extracted via OCR, and confirm that PARSE_OCR_ENABLE is enabled.
  • Check system memory usage. Confirm that no abnormal increase occurs due to uploading oversized documents. Adjust UPLOAD_FILE_MAX_SIZE to a range that meets business requirements.
