What Data for This Category Looks Like
The data sources for kitchen and bathroom appliances mainly include brand official parameter pages, compliance reports issued by national energy efficiency testing institutions, product detail pages published on e-commerce platforms, and qualified sampling lists released by industry associations. Data update rhythm fluctuates with new product launches and compliance standard adjustments, with no fixed cycle. The structure of a single product document usually includes fields such as product model, rated power, installation dimensions, energy efficiency rating, and safety certification number. Units mostly use standardized metric expressions such as watts, millimeters, cubic meters per minute, and rating numbers. Some certification fields require corresponding unique numbers from official institutions.
Constraints Imposed by These Characteristics on the "Citation Sources and Traceability" Link
Decentralized data sources and non-fixed update cycles require the traceability link to associate multiple heterogeneous knowledge bases to avoid information bias from a single source. Fields contain a large number of parameters with units and unique certification numbers, requiring strict matching of field names and units during traceability to prevent traceability errors caused by expression differences. Core information of product documents is concentrated in fixed fields, requiring recalled content to prioritize matching official compliance data sources to ensure the authority of traceability results. Additionally, certification fields must be traced to public pages of corresponding official institutions, and cannot rely solely on non-compliant content from third-party platforms.
How to Configure Settings
| Configuration Item | Recommended Approach | Basis for This Approach | |||
|---|---|---|---|---|---|
Recall Count | Top 8 entries | Single parameter document for kitchen and bathroom appliances has moderate length; too many recalls will cause context redundancy, while too few cannot cover all core parameters | |||
Similarity Threshold | 0.72–0.85 | Matches the precision requirement for product model and parameter field matching, avoids mixing low-relevance non-target product content into recall results | |||
Reranked Return Count | Top 4 entries | Prioritizes recalling official compliance documents and brand official data sources to ensure the authority of traceability content | |||
Citation Content Template | `{source_title} | {product_model} | {fieldname}: {fieldvalue} | Certification Number: {cert_no}` | Matches the core parameter fields of kitchen and bathroom appliances, facilitating quick location of corresponding information and sources during traceability |
Knowledge Base Auto-refresh Interval | 7 days | Adapts to the fluctuating rhythm of new product launches and compliance standard updates, ensuring data timeliness | |||
Field Matching Rule | Strictly match field names and units | Prevents traceability errors caused by inconsistent units, such as the expression difference between watts and kilowatts |
The parameter values provided on this page are common recommended starting points for configuration setup. Actual values are influenced by material form, data volume, and business rules. Individual circumstances require tailored analysis, and testing on local samples is recommended prior to finalizing settings.
Three Common Misconfigurations
- Phenomenon: Citation content includes parameter values with mismatched units, such as failing to correctly convert "2100 watts" to "2.1 kilowatts". Cause: The
field matching ruleis not configured, and consistency checks for field names and units are not enforced. - Phenomenon: Variable citation results for a specified product model cannot be obtained when called, and empty values are returned after entering a query. Cause: The product model variable entered in the form is not bound to the pre-node of knowledge base recall, resulting in uncompleted variable assignment.
- Phenomenon: Recalled results contain expired safety certification information, such as invalid 3C certification numbers. Cause: The
knowledge base auto-refresh intervalis not set, or the refresh cycle is too long, failing to cover the frequency of compliance information updates.
How to Verify Proper Configuration
- Upload an official parameter document for a kitchen and bathroom appliance, trigger the knowledge base parsing process, and verify whether the parsed fields include core items such as product model, rated power, and safety certification number.
- Enter a test query such as "installation dimensions of a certain model of built-in dishwasher", and check whether the recall results include the source title and field information of the corresponding document.
- Adjust the
similarity thresholdto 0.6, trigger a query, and check whether low-relevance non-kitchen and bathroom appliance content appears in the recall results to verify that the threshold configuration is effective. - Manually trigger the knowledge base refresh operation, wait for the refresh to complete, upload a new product parameter document, and verify that the new content is normally recalled.
