What the data for this category looks like
Construction and decoration investment research data primarily comes from industry standard atlases, material supplier quotation sheets, construction process specifications, bidding documents, and on-site supervision logs. Update frequency varies significantly by type: material quotations are updated monthly in line with market fluctuations, process specifications are revised annually, and bidding projects are released in real time.
Documents include structured quotation sheets (fields include material model, unit price, delivery cycle, with units of yuan/square meter, meter, day), unstructured process description PDFs, and project ledger tables (including budget amount, unit of ten thousand yuan). A single structured document can have hundreds of entries, while unstructured documents typically exceed 1,000 words per page.
What constraints do these characteristics impose on deployment and upgrade
The multi-type and high-frequency update characteristics of construction and decoration investment research data impose multiple constraints on the deployment and upgrade process.
- The large number of entries in structured quotation sheets requiring bulk imports means deployment must configure interface thresholds that support bulk uploads.
- The monthly update requirement for material quotations means upgrades must retain an incremental sync configuration entry to avoid full-volume repeated imports.
- The coexistence of multiple units in field designs means deployment must pre-set field mapping rules to prevent unit confusion after parsing.
- The real-time bidding data access requirement means upgrades must support timeout and retry configurations for external APIs.
- The large word count per unstructured process document means adjusting timeout parameters in the parsing pipeline to accommodate long-text processing.
How to set the configurations
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Construction and decoration unstructured process documents have a large number of words per page, so long-text parsing requires longer processing time |
UPLOAD_FILE_MAX_SIZE | 1000 MB | Single unstructured process documents or bulk upload compressed packages are generally large in size |
Incremental Sync Trigger Interval | 7 days | Material quotations are updated monthly, and weekly incremental sync can cover monthly market fluctuations |
Recall count | Top 10 entries | Investment research scenarios need to cover multiple types of materials and processes. Excessive recall will dilute information relevance |
Field mapping rule | Calibrated based on actual testing | Construction and decoration data have diverse fields, requiring matching of dedicated fields for quotation sheets and project ledgers |
API_RETRY_MAX_TIMES | 3 retries | Bidding APIs may experience temporary fluctuations, and limited retries can ensure data sync stability |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material format, data volume and business rules. Each scenario requires individual analysis. It is recommended to test on your own samples before finalizing settings.
Three common mistakes
- Symptom: After starting aiproxy, calling the model returns a
401 Unauthorizederror. Cause: ThePROXY_TARGETconfiguration item was not replaced with the connected service address, and the default proxy configuration remains in use. - Symptom: After bulk uploading construction and decoration quotation sheets, some core fields are empty. Cause: No pre-set field mapping rules, causing the parsing engine to fail to match construction and decoration-specific material model and unit price fields.
- Symptom: After deploying the open-source version, the shared knowledge base link cannot enable identity authentication, and access prompts
invalid token. Cause: TheSHARE_LINK_AUTHconfiguration item was not enabled, and the share authentication function is disabled by default.
How to confirm the configuration is correct
- Upload a construction and decoration material quotation sheet, check if the parsed fields match the pre-set mapping rules. Adjust the field mapping configuration if a mismatch occurs.
- Initiate an incremental sync task, check whether the task log shows successfully synced updated entries. Adjust the
PARSE_FILE_TIMEOUT_SECONDSparameter if timeout prompts appear. - Call the model interface connected via aiproxy, confirm that results related to construction and decoration investment research can be returned normally. Check the proxy address and authentication configuration if the call fails.
- Test the access permission of the shared link, verify that only authorized users can access after identity authentication is enabled. Adjust the
SHARE_LINK_AUTHrelated configuration if an abnormality occurs.
