What the data for this category looks like
Tender announcement data comes from public resource trading platforms at all levels, official government procurement websites, and official websites of industry regulatory authorities. Update frequency fluctuates with project progress: daily updates are standard during normal periods, and update frequency increases during concentrated project launch phases. Individual documents contain fields including project number, bidder information, tender scope, budget amount, bid deadline, qualification requirements, and section division. Budget amounts are measured in ten thousand yuan, time fields use standard Gregorian calendar format, and some documents include detailed parameters for each section.
What constraints these characteristics impose on model access and configuration
Public documents from multiple sources have inconsistent formats. Configure parsing rules adapted to different websites when connecting models to avoid extraction failures caused by DOM structure differences. Fields such as budget amount and bid deadline are highly structured. Require models to support precise structured extraction, and adjust context recall scope to cover complete content related to the fields. Update frequency fluctuates with project progress. Configure timed synchronization to match business rhythms to avoid data lag or resource waste. Fields have fixed units and format requirements. Configure field standardization mapping rules to unify the content format input to the model.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 8000–12000 characters | The length of individual tender announcements typically ranges from 3000 to 8000 characters. Complete context must be retained to support structured field extraction |
Recall count | Top 8–12 entries | Relevant information for tender announcements is mostly concentrated in the same section or domain range. Excessive recall will introduce irrelevant interfering content |
Rerank result count | Top 3–5 entries | Structured extraction only requires context related to core fields. Reducing returned content lowers model computation overhead |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Some large tender announcements take longer to parse. 600 seconds covers parsing requirements for most scenarios |
Similarity threshold | 0.75–0.85 | Precise matching of structured tender announcement fields is required. A threshold that is too low will introduce irrelevant announcements, while a threshold that is too high will miss valid relevant content |
FIELD_STANDARDIZATION | Enabled | Budget amount and time fields in tender announcements have differences in units and formats. Standardization unifies the content format input to the model |
The parameter values provided on this page are common starting points for determining configurations. Actual values are affected by material form, data volume, and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Mistakes
- Symptom: The model call returns a
401 Unauthorizederror. Cause: The API key for model access is not configured correctly, or the key has insufficient permissions to access the target model service. - Symptom: The AI model dropdown list in the workflow is empty. Cause: The target model has not been configured in the FastGPT model management page, or the configured model has not passed validity verification.
- Symptom: A timeout error occurs when parsing tender announcements. Cause: The configured
PARSE_FILE_TIMEOUT_SECONDSvalue is too low, and cannot cover the parsing time required for large tender announcements.
How to Confirm the Configuration is Complete
- Manually upload a locally saved tender announcement document, run the model’s structured extraction function, and verify whether the returned results cover the preset core fields.
- View the knowledge base synchronization logs to confirm that the scheduled task triggers at the set interval and pulls new tender announcement data.
- Enter a snippet of a tender announcement in the model test interface to verify that the model can correctly identify fields with units or format requirements such as budget amount and bid deadline.
- Check the model access key configuration page to confirm that the key status is valid, with no expiration or permission abnormality prompts.
