What data looks like for this category
The data for aerospace equipment financing daily reports primarily comes from official record platforms in the national defense and military industry sector, project announcements publicly disclosed by industry associations, and public bidding information. It is updated daily, covering financing projects related to aerospace equipment disclosed on the same day. Each document has a fixed structure, including fields such as project unique identifier, equipment model, manufacturing contractor, financing amount, financing method, and disclosure date. The unit for financing amount is ten thousand yuan or hundred million yuan. The date field uses standard Gregorian calendar format.
Constraints on knowledge base retrieval and recall from these characteristics
Daily updated data sources require the retrieval pipeline to support incremental recall. Avoid repeated loading of full historical data to reduce retrieval latency. The fixed field structure requires retrieval matching to prioritize preset field semantics. Irrelevant fields will interfere with recall accuracy. The numerical characteristic of large financing amounts requires retrieval to support numerical range filtering. This allows accurate matching of projects with target magnitudes. The delayed public disclosure feature requires the recall logic to have a configurable delay filtering threshold. This filters information that has not reached the public disclosure time limit. The project unique identifier requires the deduplication logic to use this identifier. This avoids repeated recall of the same project.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Recall count | Top 10 entries | The daily volume of documents for aerospace equipment financing daily reports is limited. Excessive recall increases context redundancy and reduces generation accuracy |
Similarity threshold | 0.85–0.92 | Semantic similarity of aerospace equipment financing projects has high differentiation. This range effectively filters low-correlation results |
Chunk size | 800–1200 characters | Each financing daily report document has a moderate length. This segment length preserves complete field semantics and avoids context fragmentation |
Incremental Sync Cycle | 3600 seconds | Daily updated data sources do not require high-frequency synchronization, balancing real-time performance and system resource usage |
Numeric Field Matching Switch | Enabled | Financing amount is a core screening condition. Enabling this allows accurate matching of target numerical ranges |
Delay Filter Threshold | 24 hours | Public disclosure has a delay of up to 1 day. This threshold filters information that has not reached the public disclosure time limit |
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 specific analysis. It is recommended to test on your own samples before finalizing the configuration.
Three common configuration mistakes
- The phenomenon is that retrieval results with semantic similarity lower than 0.9 are still returned. The cause is that the
Similarity thresholdconfiguration value is below the reasonable range, and the parameter has not been adjusted for the high semantic differentiation of aerospace equipment financing projects. - The phenomenon is that the page continuously displays the "Retrieving" status with no results returned. The cause is that the
Incremental Sync Cycleconfiguration is too short. The system repeatedly pulls full historical data to occupy resources, or the document parsing times out without triggering a reasonable retry mechanism. - The phenomenon is that retrieval results include duplicate financing projects. The cause is that the deduplication logic based on the project unique identifier is not enabled, or the deduplication configuration uses a non-unique field as the matching basis.
How to confirm configuration is complete
- Manually import a single aerospace equipment financing daily report document, initiate a retrieval request, check the field matching completeness of the returned results, and confirm that the segment configuration preserves complete project information.
- Initiate a retrieval request containing financing amount keywords, verify that only results matching the target numerical range are returned, and confirm that the numerical field matching switch is correctly configured.
- View the knowledge base synchronization logs, confirm that incremental synchronization runs according to the set cycle, and there are no records of repeated full synchronization triggers, to verify that the synchronization cycle configuration takes effect.
- Simulate a retrieval request with low semantic similarity, verify that the results are automatically filtered, and confirm the actual interception effect of the similarity threshold configuration.
