What the data for this category looks like
Decoration and fit-out investment research data primarily comes from industry association monthly reports, building material manufacturer product manuals, government procurement bidding announcements, construction project logs, and cost quota documents. Data update cycles vary significantly: building material market prices are updated weekly or daily, bidding announcements are released immediately as projects progress, and industry research reports are updated quarterly. Document formats include structured cost lists (with fields such as material code, brand, and unit price), unstructured construction specification PDFs, and mixed-format bidding documents. Some fields use specialized units, such as yuan per square meter, meters, and construction team workdays.
What constraints these characteristics impose on model integration and configuration
The multi-source mixed formats and specialized field characteristics of decoration and fit-out investment research data impose clear constraints on model integration and configuration. Fixed fields of structured cost lists must match the model's structured extraction capabilities to avoid field parsing mismatches. Frequently updated building material price data requires configuring an incremental synchronization mechanism to ensure the latest information is available when the model is called. Large bidding documents and long-text construction specifications require adjusting file parsing timeout and segmentation parameters to avoid parsing interruptions. The presence of multiple unit fields requires configuring unit verification rules to ensure consistent units in investment research data output by the model.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
UPLOAD_FILE_MAX_SIZE | 1000 MB | Decoration and fit-out bidding documents can reach several hundred MB per file, to accommodate large file upload requirements |
PARSE_FILE_TIMEOUT_SECONDS | 900 seconds | Large construction specification PDFs take longer to parse, to avoid timeout interruptions of parsing tasks |
maxContext | 800–1200 characters | Decoration and fit-out investment research documents often contain long-text process descriptions, to accommodate segmentation length requirements |
Recall Count | Top 8 entries | Investment research data needs to cover multiple dimensions including materials, costs, and bidding, to expand recall coverage |
Similarity Threshold | 0.72–0.78 | Distinguish similar building material models and construction processes, to avoid recalling irrelevant content |
FUNCTION_CALL_ENABLE | Enabled | Adapt to the function call requirements of Qwen2-72B-Instruct-Int8, to support structured cost data extraction |
The parameter values provided on this page are all conventional recommendations, used as a starting point for configuration. Actual values are affected by material formats, data volume, and business rules. Specific issues require case-by-case analysis, and it is recommended to test on your own samples before finalizing settings.
Three common configuration mistakes
- After batch uploading decoration and fit-out documents, only the first dozen entries parse successfully, with subsequent
ETIMEDOUTerrors returned. ThePARSE_FILE_TIMEOUT_SECONDSparameter was not adjusted, and parsing time for a single large bidding document exceeded the default threshold. - After configuring function calls for
Qwen2-72B-Instruct-Int8, structured cost data extraction performs poorly, and cannot correctly output the correspondence between material unit prices and specifications. TheFUNCTION_CALL_ENABLEconfiguration was not enabled, or a function template matching decoration and fit-out fields was not specified. - After attempting to connect casdoor identity verification, a 403 status code is returned when accessing the knowledge base. The casdoor callback domain was not added to the
ACCESS_CONTROL_ALLOW_ORIGINconfiguration, causing cross-domain requests to be blocked.
How to confirm successful configuration
- Upload a single large decoration and fit-out bidding document, check that the parsing task status is completed, with no timeout or parsing failure errors.
- Submit a test query containing building material specifications and tax-included unit prices, verify that the model can correctly extract preset investment research fields.
- After configuring the casdoor identity verification callback, verify that the knowledge base access permission verification process completes normally.
- Upload building material-related images to the workflow module, check that image content can be correctly identified and associated with corresponding investment research data.
