What This Category's Data Looks Like
Hotel and catering due diligence data mainly comes from four sources: business qualifications publicized by market supervision departments, store operation data from third-party lifestyle platforms, qualification documents of food material suppliers, and daily operation ledgers of stores. Qualification data updates quarterly. Platform operation data syncs daily. Ledger data is submitted monthly by stores. A single due diligence document typically includes fields such as basic store information, hygiene compliance rating, passenger flow fluctuation data, and supply chain partner information. Common units include person-times/day, yuan/person, square meters, and other concrete measurement identifiers.
What Constraints These Characteristics Impose on Citation and Traceability Workflows
Dispersed multi-source data requires traceability identifiers to map to three channels: regulatory public notices, third-party lifestyle platforms, and store operation ledgers. This prevents traceability confusion. Differing update frequencies across data sources require the traceability workflow to adapt to distinct timeliness verification rules. For example, qualification data must verify records updated in the most recent quarter. Platform operation data must verify synchronization status within the last 24 hours. The specificity of fields and units requires binding field names with corresponding measurement identifiers during traceability. This prevents measurement matching errors. Some third-party platform data has copyright restrictions. Traceability must clearly mark the specific node or page path used to acquire the data.
How to Configure the Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Recall Count | Top 10-15 entries | Hotel and catering due diligence data has many scattered fields, and needs to cover qualification, operation, and supply chain information. Too many entries increase context burden, too few fail to cover core fields |
Similarity Threshold | 0.75-0.85 | Must distinguish similar operation data of stores in the same category, to avoid incorrectly associating passenger flow data of nearby stores with the target store. A threshold that is too low introduces irrelevant data |
Citation Content Template | {{content}} (Source: {{source}}, Update Time: {{update_time}}) | Adapts to traceability identifier requirements for multi-source data, clearly marks source channels and update times, and complies with compliance requirements for due diligence reports |
Data Timeliness Verification Duration | Qualification type: 7 days, platform type: 1 day, ledger type: 30 days | Matches update rhythms of different data sources, ensures cited data does not exceed the compliant timeliness range |
Traceability Field Binding Switch | Enabled | Must force binding of field names with corresponding measurement identifiers, prevent unit matching errors, and meet the field specificity requirements of hotel and catering data |
Reranked Return Count | Top 5-8 entries | Prioritizes returning traceability data strongly related to the target store, improving the accuracy of due diligence reports |
The parameter values provided on this page are common 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 settings.
Three Common Misconfigurations
- Symptom: No optional values are available for variable references when configuring the traceability link. Cause: Outputs for traceability-required variables such as store identification and update time are not configured in associated data source nodes. This leaves no corresponding options in the variable pool.
- Symptom: A "Cannot redefine property: toString" error is thrown during online environment operation. Cause: The custom traceability processing script repeatedly declares the toString global method, which conflicts with the platform's built-in prototype method.
- Symptom: The citation content of generated due diligence reports does not include data source channel labels. Cause: The citation content template does not include the {{source}} placeholder, or the traceability field binding switch is not enabled. This prevents automatic association of source information.
How to Verify Proper Configuration
- Upload qualification documents and operation data for a single hotel or catering store, trigger knowledge base recall, and confirm that source tags in recall results correctly match regulatory platforms or third-party platforms.
- After configuring the citation template, generate a test due diligence report, and check that each citation entry includes actual filled values for source channel and update time.
- Adjust the similarity threshold to 0.7, run a recall test, and confirm that no irrelevant operation data from non-target stores appears in results.
- Trigger the data timeliness verification rule, upload a qualification file that has not been updated for more than 7 days, and confirm that the system prompts a data timeliness exception.
