What the Data for This Category Looks Like
Data sources for commercial real estate investment research include officially registered property qualification documents, scanned original lease contracts, monthly operation reports, commercial district passenger flow monitoring data, and third-party industry research documents. Update frequency varies by document type: lease contracts are updated at renewal milestones, operation reports are updated monthly, and commercial district data is updated quarterly. Document structure has two categories: structured tables and long text. Structured tables contain fields such as property building area, rental unit price, and core operation indicators, with units of square meters, yuan per square meter per day, respectively. Long text content includes investment promotion brochures, compliance rectification reports, and similar materials.
Constraints Imposed on the Citation Source and Traceability Link
The scattered, multi-source data nature requires traceability processes to associate unique identifiers for data from different sources, preventing cross-source data confusion. The mixed structure of structured tables and long text requires traceability to support precise positioning of both file paragraphs and structured table fields, rather than relying only on file names. The varied update cycles require traceability to mark the collection or update time of data, helping users assess information timeliness. Clear field and unit requirements require traceability to return the unit information matching each field, avoiding numerical ambiguity in investment research analysis. Commercial real estate investment research data has strong interconnections, so traceability must support cross-reference association across multiple documents, improving information credibility.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
recall_count | top 8 | Commercial real estate investment research data is mostly a mix of structured tables and long documents; 8 entries cover core indicators and associated context |
similarity_threshold | 0.72–0.85 | Need to distinguish rental data for different properties in the same commercial district; a threshold that is too low will retrieve irrelevant industry data |
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | Large lease contract PDFs take longer to parse; 120 seconds covers parsing for standard files |
enable_cite | enabled | Citation sources must be clearly identified for investment research scenarios; when enabled, the system automatically generates citation traceability information |
structured_data_cite_fields | all core fields | Commercial real estate structured data requires complete traceability of field information, preventing missing key identifiers in investment research analysis |
enable_unknown_answer | disabled | Investment research scenarios require strict limits on response scope; when disabled, the system only returns citations for questions covered by the knowledge base |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume and business rules. Each scenario requires targeted analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Phenomenon: Citations from knowledge base files are still returned when searching for questions outside the knowledge base coverage. Cause: The default enabled state of the
enable_unknown_answerparameter was not disabled, causing the system to force association with existing documents to generate a response. - Phenomenon: No
citefield is present in the conversation interface response results. Cause: Theenable_citeconfiguration item was not enabled, or the citation traceability switch was not turned on in the knowledge base management page. - Phenomenon: Traceability for structured operation tables only returns the file name, without marking corresponding field information. Cause: The
structured_data_cite_fieldsparameter was not configured, and the core fields requiring traceability were not specified.
How to Verify Proper Configuration
- Submit a simulated retrieval request, enter a specific question related to commercial real estate investment research, and check whether the returned results include the
citefield. The field content must include the file name, paragraph position or field identifier. - Construct a question outside the knowledge base coverage, and confirm that no citation source information is returned in the results.
- Upload a structured property operation table, retrieve the corresponding indicators, and check whether the traceability information includes field and unit information.
- View the logs of knowledge base parsing tasks, and confirm that no timeout errors corresponding to the
PARSE_FILE_TIMEOUT_SECONDSparameter are triggered.
