What the Data for This Category Looks Like
Black home appliance parameter data primarily comes from official brand product pages, national energy efficiency label filing databases, and third-party authoritative testing institution reports. Update schedules follow these rules: real-time synchronization for new product parameters from brands, quarterly updates for energy efficiency data, and irregular updates for after-sales policies as brands adjust them.
The document structure for a single model includes fields such as model identifier, core performance parameters, energy efficiency rating, physical dimensions, and after-sales support. Power units are watts (W) or kilowatts (kW). Energy efficiency ratings are marked with levels 1 through 3. The model field must include the brand prefix and serial number.
Constraints Imposed on Citation Sources and Traceability
Different data sources have varying credibility levels. Parameters from official brand product pages have higher priority than third-party reports. The traceability link must mark the source type.
Update frequency is fast, with incremental update requirements. Configure periodic synchronization tasks to avoid data lag.
Fields and units follow fixed specifications. Accurately match field names and units during retrieval to avoid parameter confusion across models.
A single model has a large number of document fragments. Reasonably control the retrieval range to ensure accurate citations and avoid redundant information interfering with due diligence conclusions.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Recall Count | Top 8-12 entries | Black home appliance single model parameter documents have many fragments after splitting, so this range must cover complete sources for core parameters |
Similarity Threshold | 0.75-0.85 | Must distinguish parameters of different models under the same brand and series, avoid retrieving fragments from non-target models |
PARSE_FILE_TIMEOUT_SECONDS | 300 seconds | Third-party testing reports are usually lengthy, so sufficient time must be reserved for parsing |
Segment Length | 800-1200 characters | The field block length of black home appliance parameter documents is moderate, so complete parameter groups can be retained after segmentation |
Knowledge Base Incremental Sync Cycle | Every 7 days | Energy efficiency data is updated quarterly, incremental sync reduces resource consumption of full crawling |
Rerank Return Count | Top 3-5 entries | Must return the most accurate parameter sources, avoid excessive redundant citations interfering with due diligence results |
The parameter values provided on this page are all common recommended starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require case-by-case analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Configuration Mistakes
- The symptom is that retrieval matches knowledge base fragments but only returns a single citation. The cause is that the
rerank return countparameter was not configured, and the default configuration results in only one returned entry. - The symptom is a
408 Request Timeouterror when parsing third-party testing reports. The cause is that thePARSE_FILE_TIMEOUT_SECONDSvalue is set too low, failing to reserve sufficient time for document parsing. - The symptom is cross-model parameter confusion in retrieval results. The cause is that the similarity threshold is set too high, causing accurate fragments of the target model to not be retrieved, and instead matching parameter fragments from similar models.
How to Verify Correct Configuration
- Upload the parameter document for a single black home appliance model. Check if the parsed segments retain complete parameter groups, and verify that the
segment lengthconfiguration takes effect. - Initiate a smart due diligence query. Check if the returned citation sources are marked with data source types, and confirm that the traceability function is enabled.
- View the knowledge base sync logs. Confirm that the incremental sync task runs according to the set cycle, and verify the
knowledge base incremental sync cycleconfiguration. - Test queries for different models under the same brand and series. Confirm that retrieval results only match parameter fragments of the target model, and validate the reasonableness of the similarity threshold configuration.
