What Data for This Category Looks Like
Tender announcement data primarily originates from official websites of government procurement public service platforms, public resource trading centers of various provinces and cities, and industry regulatory authorities. Update frequency adjusts based on project scale: major engineering tender announcements are released in real time, while routine procurement announcements are updated daily. Each document follows a fixed structure, including fields such as project name, tender number, purchaser information, budget amount, bid submission deadline, prequalification requirements, and contact information. Budget amount uses Chinese yuan (yuan or ten thousand yuan) as its unit. Time fields use the uniform format of Gregorian calendar year-month-day hour-minute.
Constraints Imposed by These Characteristics on Citation Sources and Traceability
First, most data sources use official domains. When tracing sources, verify the legitimacy of source domains to prevent non-official content from being included in citations. Second, update frequencies vary. Configure an incremental synchronization mechanism to ensure cited tender announcements are the latest released versions. Third, fixed document structures and clear unique identifier fields (such as tender number) require associating corresponding documents using unique identifiers during traceability. Using only text matching cannot achieve accurate association. Fourth, multi-field content structures require retaining field association relationships during chunking. This ensures cited content fragments can be accurately positioned to the corresponding bidding link.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
recall_count | 3-5 entries | Single tender announcement documents have relatively long content. Excessive recall will lead to redundant context, while a small number of recalls can accurately match core bidding-related content |
similarity_threshold | 0.75-0.85 | Tender announcement content has high professionalism. A relatively high similarity threshold is required to filter irrelevant matches and avoid recalling non-bidding-related announcements |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Tender announcements may contain a large number of attachments or long text, so extended parsing timeout is needed to ensure complete parsing |
chunk_length | 800-1200 characters | Tender announcements have many fields and standardized content. This chunk length can retain the complete semantics of field associations |
knowledge_base_incremental_sync_cycle | Once daily | Routine procurement announcements are updated daily. Incremental synchronization ensures cited content is the latest version |
variable_render_mode | {{}} format | Matches the variable compatibility logic fixed in version V4.8.18-FIX2, ensuring citation source fields can render correctly |
The parameter values provided on this page are conventional recommendations used as a starting point for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Phenomenon: When the chat interface is called, it returns the citation list first and then the answer, and the return order cannot be adjusted. Cause: The
return_reference_orderparameter is not configured correctly, and the default value uses the pre-return mode. - Phenomenon: Timeout errors occur when tender announcements are parsed, with error code 504. Cause: The configured value of
PARSE_FILE_TIMEOUT_SECONDSis less than the actual time required for parsing, resulting in parsing timeout. - Phenomenon: Cited tender announcement fields cannot be rendered into readable text normally, and
{{field_name}}is output as-is. Cause: The {{}} format configuration forvariable_render_modeis not enabled, or the version is lower than V4.8.18-FIX2, which has variable parsing compatibility issues.
How to Verify Proper Configuration
- A single tender announcement document is uploaded to the knowledge base, automatic parsing is triggered, and the parsed chunked content is checked to confirm whether it retains the association relationship between core fields such as project name and tender number.
- A test query is initiated, keywords related to bidding are entered, and the returned results are checked to confirm whether the cited sources are tender announcement content from official domains.
- A workflow or chat interface is called, a custom knowledge base ID variable is passed in, and the knowledge base search node is verified to confirm whether it can correctly associate with the specified tender announcement knowledge base.
- System logs are checked to confirm there are no error messages related to parsing timeouts, variable rendering failures, or abnormal citation sources.
