What the data for this category looks like
Bid rejection item bidding data is sourced from publicly available bid rejection announcements on public resource trading platforms and internal enterprise tender filing archives. Data updates align with status changes of corresponding tender projects, with no fixed cycle. Updates are completed within 24 hours after a single project is rejected. Each data document includes fields such as project identification number, tender subject, bid rejection reason, number of involved bid sections, original bid limit price, public announcement release time, and more. Field units are mostly "unit", "yuan", and "year/month/day". Some fields have multiple values; for example, involved bid sections can include multiple independent bid section numbers.
What constraints these characteristics impose on multi-turn dialogue and prompt engineering
Dispersed data sources require multi-turn dialogue to associate and recall across multiple knowledge bases. The context window must be restricted to retain only data related to the current tender project to avoid interference from cross-project content. No fixed update rhythm requires the dialogue process to support real-time knowledge base refresh, and fixed timed synchronization mechanisms should not be relied on. Fixed fields and units require prompts to clearly specify extraction rules to avoid unit confusion or missing fields. The existence of multi-value fields requires multi-turn dialogue to support step-by-step follow-up questions to confirm details, ensuring complete extracted information. The project identification associated with a single data entry must be retained as a key context identifier during multi-turn interactions to prevent confusion of dialogue context.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 8000–12000 characters | Matches the average length of a single bid rejection item document, retains context information for the current tender project to avoid cross-project interference |
recallTopK | Top 3–5 entries | There are relatively few single-project entries for bid rejection item data; excessive recall will introduce irrelevant announcement content |
similarityThreshold | 0.75–0.85 | Filters low-relevance bid rejection announcements to ensure recalled content is strongly associated with the current tender project |
promptTemplate | Extract according to the bid rejection item field template, retain the project identification number and corresponding units | Matches the fixed field structure of bid rejection items to avoid incorrect unit or field extraction |
timeout | 600 seconds | Cross-platform recall of announcements takes a long time, prevents early termination of dialogue |
PARSE_FILE_MAX_SIZE | 20 MB | Adapts to the size of batch-imported bid rejection announcement archive files |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require individual analysis, and testing on local samples is recommended prior to final deployment.
Three Common Mistakes
- Symptom: Dialogue terminates directly after the knowledge base recall step with no follow-up response. Cause: The
timeoutparameter is set too short, and the request times out before cross-platform announcement recall is completed. - Symptom: Dialogue frequently returns 504 gateway timeout errors. Cause: The
similarityThresholdis set too high, resulting in insufficient valid data being recalled, leading to system wait timeout. - Symptom: Ordinary dialogue sessions automatically pull in bid rejection item knowledge base content. Cause: The default knowledge base association switch is not disabled, causing irrelevant data to be recalled in non-specified scenarios.
How to Verify Correct Configuration
- Upload a single bid rejection item announcement document, verify that extracted results include preset fields and corresponding units.
- Initiate a multi-turn dialogue involving multiple tender projects, confirm that context only retains bid rejection item data for the current project.
- Check dialogue execution logs to confirm no early termination or timeout errors occur.
- Test plugin trigger scenarios, confirm that the prompt template is only called in specified links.
