What data for this category looks like
Data for building construction engineering intelligent due diligence comes mainly from housing and urban-rural development department filing documents, construction logs, supervision reports, cost accounting documents, completion acceptance materials, and similar sources. Update rhythm follows project phases: project initiation, foundation construction, main structure construction, completion acceptance, and other phases. Update cycles range from months to years. Document structure includes structured forms such as project filing forms and cost lists, and unstructured text such as construction logs and supervision rectification notices. Fields include project number, floor area (unit: ㎡), project cost (unit: ten thousand yuan), start and completion dates, construction unit qualification level, and other exclusive information.
What constraints do these characteristics impose on the citation sources and traceability link?
Building construction engineering due diligence data is scattered across sources and updated in phases. Traceability must accurately bind the project's unique identifier and construction phase to avoid mixing materials from different periods of the same project. Documents include structured and unstructured content. Traceability must support dual citation markers: field-level and full-text. Exclusive fields and units require traceability to retain field names and unit information, avoiding citation ambiguity across categories. The long-cycle update rhythm requires traceability to track the effective time of materials, ensuring that the currently valid version is cited.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
Recall count | Top 10-15 entries | Building construction engineering due diligence documents come from many scattered sources. This range must cover key evidence from core links such as construction, cost, and acceptance to avoid missing important materials |
Similarity threshold | 0.75-0.85 | Building construction engineering documents contain a large number of professional standardized terms. A threshold that is too low will introduce irrelevant material quotations or materials from other projects. A threshold that is too high will fail to retrieve associated evidence across documents |
Maximum segment length | 1000-1200 characters | Construction logs and supervision reports for building construction engineering are mostly long paragraph records. A segment that is too long will lose contextual association, while a segment that is too short will destroy the integrity of professional terms |
Citation source display format | Display file name + field name + update time | Building construction engineering materials are updated by project phase. Clearly marking the time and corresponding field avoids confusing files from the same project across different periods |
Knowledge base version matching | Match by project number + phase | Building construction engineering materials are updated in phases. Bind the project's unique identifier and construction phase to ensure traceability points to valid files from the corresponding period |
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 individual analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- The symptom is that citation sources displayed during conversations include non-current project building construction engineering materials. The cause is that the
Knowledge base version matchingparameter is not configured, and the project number and construction phase are not bound. This leads to retrieving invalid documents across projects. - The symptom is that citation sources do not display field names or unit information. The cause is that the
Citation source display formatis not configured, and only the file name is displayed. This prevents users from clearly identifying the specific data item being cited. - The symptom is that variable references in the knowledge base search module cannot correctly match building construction engineering exclusive fields. The cause is that exclusive variables such as project number and floor area are not bound in the configuration, leading to variables that cannot correspond to actual fields in the document.
How to Confirm Proper Configuration
- Upload a completion acceptance filing form for a building construction engineering project. Initiate a query that includes "the floor area of this project". Check whether the citation source displays the file name, the field "floor area", and the filing date.
- Upload materials from different construction phases of the same project. Initiate a query that includes "construction progress during the main structure phase". Check whether citation sources are distinguished by phase and project number, and do not mix up documents from different phases.
- Check the citation source area in the conversation interface. Confirm that relevant information is displayed in the configured format, with no missing fields or units.
- Adjust the
Similarity thresholdto 0.7. Initiate a query that includes "steel bar site inspection". Check whether all retrieved documents are related to construction inspection content for building construction engineering, with no irrelevant non-engineering documents.
