What the data for this category looks like
Commercial building construction financial report data primarily comes from internal company engineering ledgers, completed project settlement documents, monthly progress payment declaration forms, annual audit reports, and project filing archives from housing and urban-rural development authorities. Data update cadence follows project milestones: monthly progress payment declaration forms update monthly, annual audit reports update per fiscal year, and completed settlement documents generate and archive once after project completion. Document structures typically include modules such as project overview, cost breakdown details, progress payment records, variation order items, and audit adjustment explanations. Fields include project ID, building number, cost item code, settlement amount (in RMB yuan), construction period (in calendar days), construction area (in square meters), and other unique identifying tags.
What constraints do these characteristics impose on the citation sources and traceability workflow?
The multi-source, decentralized nature of commercial building construction financial reports requires the traceability workflow to associate unique identifiers across multiple data sources such as internal ledgers, filing archives, and audit reports, to avoid cross-data-source confusion. The varying update cadences of different documents require traceability markers to distinguish version identifiers for incremental updates and full updates, to ensure referenced content matches the project status at the corresponding time node. The presence of unique fields such as project ID and building number requires the recall phase to prioritize matching these fields, using general keywords as secondary matching items to reduce false recall rates. The relatively long content length of individual financial report documents requires traceability to accurately locate the specific position of the referenced snippet in the original document, to avoid situations where the snippet alone cannot be traced back to the original file.
How to Configure Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
recall_match_fields | ["project_id", "building_no", "cost_item_code"] | Match the unique project, building, and cost item codes specific to commercial building construction financial reports, to avoid false recalls caused by generic fields |
max_context | 800–1200 characters | Individual commercial building construction financial report snippets are relatively long; retaining sufficient context ensures complete citation logic |
similarity_threshold | 0.75–0.85 | Unique field matching takes priority; setting a medium range balances recall precision and coverage |
UPLOAD_FILE_DUPLICATE_MODE | content_hash + metadata_id | Combine file content hash and project metadata ID for deduplication, to avoid duplicate uploads of financial reports for the same project with different versions |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Commercial building construction financial report files typically have large file sizes; reserve sufficient parsing time |
enable_metadata_id_in_reference | Enabled | Enable metadata ID as the traceability identifier, to ensure referenced content links to the unique fields of the original file |
The parameter values provided on this page are general recommendations used as a starting point for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require case-by-case analysis, and it is recommended to test against your own samples before finalizing settings.
Three Common Misconfigurations
- After uploading 100 5KB files, half fail during training, and the console shows "parsing failed" with status code 400. The cause is that some files lack the
project_idfield in their metadata, and parsing interrupts because no unique commercial building construction project identifier is matched. - After switching the conversation component to variable reference mode, the temperature adjustment slider disappears from the "model parameter configuration" area. The cause is that variable reference mode inherits preset parameters from context variables by default; configure temperature values through context variables instead.
- The
{{id}}field in the knowledge base citation template returns a null value, and the generated citation traceability does not display a unique identifier. The cause is that theenable_metadata_id_in_referenceconfiguration is not enabled, and no unique metadata ID for commercial building construction projects is linked as a traceability identifier.
How to Confirm Configuration is Active
- Upload a single commercial building construction financial report file, and check that the parsing log returned by the console includes the preset unique fields to confirm the matching rules take effect.
- Upload two commercial building construction financial report files with identical content but different metadata, and check that only entries matching the deduplication rules are retained after knowledge base deduplication to confirm the deduplication configuration takes effect.
- Submit a test query, and check that the traceability fields referenced in the generated results include project-specific identifiers to confirm the traceability configuration takes effect.
- Adjust the recall matching field range, and compare changes in recall result precision to confirm the matching configuration takes effect.
