Data Overview
Data sources for residential development research reports include residential project filing data publicly released by housing and construction authorities, annual and semi-annual performance announcements of listed real estate companies, and special regional residential market reports from professional real estate research institutions. Update cycles cover monthly, quarterly, and annual: monthly sales data is updated monthly, quarterly market supply and demand analysis reports are updated quarterly, and annual industry white papers are updated each calendar year. A single document typically includes five modules: basic project information, development progress, cost breakdown, market supply and demand, and policy relevance. Core fields include project name, land area, calculated floor area, development cycle, and unit cost. Corresponding units are square meters, months, and ten thousand yuan per square meter.
Constraints for Citation and Traceability
Multi-source and heterogeneous data sources cause inconsistent field naming. For example, some documents refer to "calculated floor area" as "sellable area". Field mapping must be completed during traceability to accurately display source information. Data sources with different update frequencies require precise time range filtering during traceability, to avoid recalling outdated monthly sales data or obsolete policy analysis. Long-text research reports must be traced to specific chapters, not entire documents. Otherwise, users cannot locate the corresponding analysis content. Specialized fields and units require retaining original unit markings during traceability, to avoid confusion in cost units.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
chunk_size | 800–1200 characters | Residential development research reports include long-text cost breakdown and policy analysis modules. This segment range preserves module integrity and avoids splitting that breaks logical connections |
recall_top_k | Top 8–12 results | Residential research reports involve multi-dimensional data including projects, markets, and policies. Sufficient relevant entries must be recalled to cover complete analysis logic |
similarity_threshold | 0.75–0.85 | Filter commercial real estate, cultural tourism real estate and other data unrelated to residential development, to accurately match keywords for the target scenario |
source_cite_mode | Cite by document chapter | Residential research reports have clear structures. Citing by chapter allows traceability to point directly to specific analysis modules, rather than entire documents |
parse_file_timeout | 300 seconds | Single residential research report documents are lengthy, requiring sufficient time to complete structured parsing and field mapping |
enable_chunk_cite | Enabled | Sources of text fragments directly linked to the query must be displayed, not just document names, to meet traceability requirements for this scenario |
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 specific analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Phenomenon: Redundant knowledge base search inputs and original prompt text for recalled fragments appear in chat replies. Cause:
source_cite_modeis not correctly configured to only display answer-associated fragments, and the full-process input and output display switch is mistakenly enabled. - Phenomenon:
504 Gateway Timeouterrors occur when parsing long documents. Cause:parse_file_timeoutis not set to a sufficient duration. Structured parsing of single residential research reports takes a long time. - Phenomenon: Field units displayed during traceability do not match the original text, or field names do not match. Cause: Custom mapping is not implemented for specialized fields of residential development research reports. Default parsing rules cannot adapt to specialized terms such as "calculated floor area" and "unit cost".
How to Verify Correct Configuration
- A query including a specific residential project name is submitted, and the cited sources in the reply are checked for marking of the corresponding research report chapter or document name.
- Cited fragments in the reply are reviewed to confirm only text content directly linked to the query is included, with no redundant search process prompts.
- A test for parsing a single residential development research report is triggered, and it is checked whether a chapter-divided citation index is generated after parsing completes.
- The
similarity_thresholdparameter is manually adjusted, and recall results are verified to meet expected relevance filtering effects as the threshold changes.
