What this type of data looks like
Data sources for commercial real estate research reports include public industry monitoring databases, commercial project operation data disclosed by listed real estate companies, and public reports on regional commercial markets. Updates follow a primarily quarterly routine schedule. Special reports for hot business districts are released temporarily based on market changes.
Document structure includes four parts: basic project information, operation data, competitor benchmarking, and market trend analysis. Fields include project latitude and longitude, base rent value, operation area, customer group and business format composition, among others. Rent is priced per square meter per day. Operation area is measured in square meters. Individual content lengths vary widely, from thousands to tens of thousands of characters.
What constraints these characteristics impose on model integration and configuration
The multi-source heterogeneous nature of commercial real estate research reports requires configuring dual parsing templates for structured reports and unstructured text during the integration phase, corresponding to different field mapping parameters.
Irregular update rhythms require configuring incremental sync trigger rules that distinguish between routine quarterly updates and temporary change reports, to avoid mismatches between sync cycles and data update rhythms.
Generally long document lengths require adapting model context window configuration parameters to avoid truncation of core operation data.
Strict requirements for units and pricing rules of professional fields require configuring field validation rules to ensure unit consistency of imported data.
How to set configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 8000–16000 characters | Most individual commercial real estate research reports range from 5000 to 12000 characters, so this range ensures core operation and trend content is fully loaded |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Individual research reports require parsing multiple sections, so this value prevents task interruptions due to insufficient parsing duration |
vector_field_weight | Set structured field weight to 0.7, unstructured field weight to 0.3 | Commercial real estate retrieval needs prioritize accurate operation data and location information, so structured fields have higher priority |
incremental_sync_interval | 86400 seconds (1 day) | Routine research reports are updated quarterly. Daily incremental sync covers temporarily released change reports |
similarity_threshold | 0.75–0.85 | Filters low-relevance general industry reports, ensuring returned results closely match commercial real estate topics |
rerank_top_n | Top 10 entries | Commercial real estate competitor analysis and location comparison require a small number of accurate results, to avoid interference from excessive redundant information |
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 situations require specific analysis, and it is recommended to test on local samples before finalizing.
Three common configuration errors
- Scenario: When configuring an external vLLM as a vector model, the interface displays a "connection refused" error, and model addition cannot be completed. Cause: Cross-domain access rules for the vLLM service are not configured, or the forwarding service port does not match the actual listening port of vLLM.
- Scenario: After parsing commercial real estate research reports, core operation fields are missing or units are inconsistent. Cause: Field validation rules are not configured, and unit and format unified processing is not performed for multi-source imported data in different formats.
- Scenario: When uploading large commercial real estate research reports, parsing tasks terminate automatically with no clear error prompt. Cause: The
maxContextparameter is not adjusted to a range suitable for document length, and the default context window cannot load complete report content.
How to confirm configuration is complete
- Enter the model management page, check that the status of the connected vector model and language model is "normal", and verify that the configured listening port matches the actual service port.
- Upload a single typical commercial real estate research report to trigger a parsing task, and check that the parsing log has no field missing, format error or timeout prompts.
- Initiate a retrieval test for commercial real estate topics, and verify that the field matching logic of the returned results conforms to the preset weight rules.
- Trigger a manual incremental sync task, and check that the sync record only contains updated research report data, with no duplicate synchronized historical content.
