What the data for this category looks like
Tender announcement data is sourced from public resource trading centers at all levels, official government procurement platforms, and industry-specific tender websites. Updates are triggered by the release of individual tender projects, with no fixed bulk cycle. Each document follows a standardized structure, including fixed fields such as project name, tender number, buyer entity information, budget amount (unit: ten thousand RMB), qualification threshold requirements, bid deadline, submission method, and contact channel. Some projects include technical parameter or qualification requirement attachments.
What constraints these characteristics impose on knowledge base retrieval and recall
Multi-source and heterogeneous data sources create minor differences in document formats across platforms. Field mapping rules must be unified before recall to avoid missing or misaligned fields in retrieval results. The non-fixed bulk update rhythm requires the knowledge base to use an incremental synchronization mechanism, only synchronizing newly added or updated tender announcements. This avoids excessive computing resource usage from full refreshes. Structured fields including numeric budget amounts and time-sensitive bid deadlines require combining semantic retrieval and structured retrieval to accurately match numeric conditions and time ranges. Scenarios with attached technical parameter attachments require the retrieval link to support parsing and recalling attachment content. Key matching information will be missed otherwise.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Tender announcement qualification requirements and technical parameter paragraphs are lengthy. This segment length adapts to long text splitting while preserving semantic integrity |
recallCount | Top 10–15 results | A large number of similar competitive tender announcements exist. Too many recalled results increase context processing load, while too few fail to cover valid matching items |
similarityThreshold | 0.75–0.85 | Tender announcements have relatively high keyword recognition. A threshold that is too low may introduce irrelevant announcements, while a threshold that is too high will miss accurate matching results |
PARSE_ATTACHMENT | Enabled | Some tender announcements include technical parameter attachments. Attachment content must be parsed and included in the retrieval scope |
INCREMENTAL_SYNC_INTERVAL | Every 1–2 hours | Tender announcement updates have no fixed cycle. Short-interval incremental synchronization ensures knowledge base timeliness while avoiding excessive resource usage |
structuredRetrievalEnabled | Enabled | Tender announcements include structured fields such as budget amount and bid deadline. Structured retrieval must be enabled to match numeric and time conditions |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require individual analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Phenomenon: A "Connection error" is returned when calling the semantic retrieval tool, and the interface displays a network abnormality prompt. Cause: Access permissions for the target tender platform have not been configured, or the platform interface has triggered current-limiting mechanisms leading to connection interruptions.
- Phenomenon: The knowledge base cannot add new tender announcements, and an upload prompt indicates storage space is exceeded. Cause: The
KNOWLEDGE_BASE_STORAGE_LIMITparameter has not been adjusted. The default storage space quota is insufficient to accommodate bulk tender announcement files. - Phenomenon: Generated replies do not include source identifiers, making it impossible to confirm whether content originates from the knowledge base. Cause: The
enableCitationconfiguration item has not been enabled, and the citation source display function has not been activated.
How to Verify Proper Configuration
- Perform a single tender announcement upload test, and check whether the parsed fields fully match the original document's project information, qualification requirements, and other content.
- Submit a retrieval request to verify that both semantically matching announcement content and structured field matching results are returned.
- After enabling
enableCitation, generate a reply and check whether corresponding source links or number identifiers for the tender announcement are included. - View the incremental synchronization log to confirm whether newly added tender announcements are automatically synchronized to the knowledge base at the set interval.
