What Data for This Category Looks Like
Commercial real estate research report data primarily originates from public research outputs of industry associations, professional consulting firms, local housing and urban-rural development departments, and business district operators. Updates follow a primarily quarterly regular report schedule, with occasional special reports covering business district dynamics and policy adjustments. Document structures typically include a cover page, core indicator section, district analysis chapters, typical project cases, and an appendix. Fields include project name, business district grade, rent per unit area, vacancy rate, and others. Common units are yuan per square meter per day, percentage, ten thousand person-times, and more. Some reports include metadata such as compiling organization and release date.
What Constraints These Characteristics Impose on the Citation Source and Traceability Link
The segmented district attribute of commercial real estate research reports requires precise matching of fields such as business district and project name in the document during traceability, to avoid incorrect cross-district associations. The irregular update rhythm requires the traceability link to support incremental updates and metadata synchronization, to ensure the timeliness of retrieval result sources. Long documents with professional indicators will have their indicator-to-report binding broken if split improperly, leading to failure to associate complete report metadata during traceability. Additionally, indicator fields with multiple units require synchronous display of corresponding unit information during traceability, to prevent users from confusing statistical calibers of different reports.
How to Set Configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Segment Length | 800–1200 characters | Professional paragraphs in commercial real estate research reports contain complete indicators and analysis logic. This range avoids splitting that breaks field associations |
Number of Retrieved Entries | Top 10 | Covers multi-dimensional analysis content in professional research reports, avoids missing key sources |
Similarity Threshold | 0.75–0.85 | Filters low-relevance retrieval results, ensures matching accuracy of traceability sources |
Citation Metadata Toggle | Enabled | Displays key traceability information such as report compiling organization and release date, meets professional traceability needs of industry users |
Knowledge Base Incremental Update Cycle | Weekly | Adapts to the irregular update rhythm of commercial real estate research reports, ensures synchronization between metadata and document content |
Number of Rearranged Returned Entries | Top 5 | Focuses on core sources, avoids excessive entries interfering with user reading |
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. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Symptom: No retrieval results when passing a custom knowledge base variable in a workflow. Cause: Permission mapping for the
Knowledge Base Selection Variableis not configured, causing the variable to fail to bind correctly to the target knowledge base. - Symptom: The API response displays the citation list before the answer content. Cause: The
Return Citations Firstconfiguration item is enabled, or theCitation Display Priorityparameter is not adjusted. - Symptom: Traceability snippets missing key fields such as business district name and rent unit. Cause: The segment configuration for
Retain Document Metadatais not enabled, causing split snippets to lose bound report metadata.
How to Verify Proper Configuration
- Upload a commercial real estate research report document, initiate a retrieval query containing professional indicators, and check if metadata such as the document's compiling organization and release date is displayed below the answer.
- Call the API to pass a custom knowledge base variable, check if the workflow correctly calls retrieval results from the corresponding knowledge base, and verify the validity of the variable reference.
- Adjust the
Similarity Thresholdto a range below the set value, observe changes in the relevance of returned results, and confirm that the parameter configuration has taken effect. - Upload a new research report document, wait for the set incremental update cycle, initiate a retrieval query, and confirm that the new document's source can be correctly traced.
