What the data for this category looks like
Data sources for commercial property intelligent due diligence reports include local housing and urban-rural development department filing systems, property party monthly rent ledgers, water and electricity energy consumption payment vouchers, surrounding business district passenger flow monitoring data, and real estate property right registration documents. Update frequencies vary: rent ledgers are updated monthly, property information is updated quarterly, and surrounding passenger flow data is updated weekly. A single report typically includes four core modules: property overview, rent revenue, operation and maintenance records, and surrounding supporting facilities. Each module contains subfields. Fields and units follow industry general standards: building area is measured in square meters, monthly rent is measured in yuan per square meter per month, property registration numbers are alphanumeric combination strings, and energy consumption data is measured in kilowatt-hours.
What constraints these characteristics impose on deployment and upgrade
Multiple data sources with varying update frequencies require configuring multi-data-source synchronization rules during deployment. Distinguish full and incremental synchronization trigger logic to avoid resource waste. Long document structures require tailored chunking and context parameters to prevent core module information from being split apart. Multi-field document structures require knowledge base field mapping rules that align one-to-one with report modules to avoid data confusion. Access to third-party passenger flow data requires configuring stable retry and timeout mechanisms to handle external interface instability. During upgrade, maintain compatibility with old synchronization scripts to ensure data links with different update frequencies do not interrupt. Add sensitive information filtering rules to meet data compliance requirements.
Configuration Settings
| Config Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 1000 MB | Single commercial property due diligence reports often span dozens of pages, and individual file sizes typically do not exceed 1000 MB |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Long document parsing requires extended time to avoid interrupting the parsing process due to timeout |
maxContext | 8000–12000 characters | Adapt to context association after long document chunking, covering complete module information |
Recall count | Top 8–10 entries | Commercial property data has many fields, requiring sufficient recall volume to cover core module content |
Incremental synchronization interval | 3600 seconds | Matches the minimum granularity of monthly rent ledger updates, balancing real-time performance and resource consumption |
Sensitive word filtering rules | Trigger filtering based on property and owner information | Prevent sensitive field leaks and meet data compliance requirements |
The parameter values provided on this page are conventional recommendations used as a starting point for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require specific analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Phenomenon: File upload succeeds but parsing fails, and the interface displays a
504 Gateway Timeouterror. Cause: ThePARSE_FILE_TIMEOUT_SECONDSparameter is not adjusted, and long document parsing exceeds the default timeout limit. - Phenomenon: Knowledge base recall results fail to cover the rent revenue module, and core data is not retrieved. Cause: The
Recall countparameter is set too low, failing to match the multi-field requirements of commercial property reports. - Phenomenon: All model calls report errors, and due diligence reports cannot be generated normally. Cause: No third-party passenger flow data interface key is configured, or the key has expired, causing the data link to interrupt and triggering chain errors.
How to Verify Proper Configuration
- Upload a standard commercial property due diligence report, and confirm that parsing progress completes within the set timeout period.
- Initiate a question and answer targeting the core modules of the report, and verify that recall results cover the four modules: property, rent, operation and maintenance, and surrounding supporting facilities.
- View data source synchronization logs to confirm that incremental synchronization tasks automatically trigger and complete data updates at the set interval.
- Test team member permission settings, and confirm that team members can access the deployed due diligence report application and call related functions.
