What the Data for This Category Looks Like
Infrastructure engineering research report data primarily originates from financial institution industry research reports, public notices issued by housing and urban-rural development authorities, industry bidding platforms, design institute deliverables, and construction unit monthly progress reports. Update frequency varies significantly by document type: bidding announcements are updated in real time, annual industry research reports are released quarterly, and individual project progress reports are updated monthly. Document structures typically include basic project information, budget details, construction node plans, and material consumption ledgers. Fields covered include project ID, budget amount (unit: ten thousand yuan), construction period (unit: days), contractor qualification level, compliance approval document number, and more. Some large project reports can reach tens of thousands of words in length.
Constraints for Model Integration and Configuration
The long-form documents, multiple fields, and varied update cycles of infrastructure engineering research reports create multiple constraints for the model integration and configuration process. Individual documents have high word counts, so long text segmentation logic must be adapted to avoid truncating core information such as budget details and construction nodes. Multiple fields include numerical content with specific units, so metadata indexing rules must be configured to ensure the model can associate fields with their unit semantics during recall. The coexistence of real-time updated bidding announcements and periodically released research reports requires distinguishing trigger logic for incremental synchronization and full updates, to avoid duplicate indexing or data lag. Some compliance-related fields require separate metadata filtering rules to support precise retrieval requirements.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_SEGMENT_LENGTH | 800–1200 characters | Aligns with the distribution of core fields in infrastructure engineering research reports, avoiding truncation of key information such as budget and construction period |
RECALL_TOP_K | Top 8–12 results | Covers retrieval needs for multiple associated infrastructure projects, balancing recall accuracy and response speed |
SIMILARITY_THRESHOLD | 0.72–0.85 | Filters non-infrastructure documents with low semantic matching, retaining valid associated results for detailed projects |
API_ENABLE_MODEL_LIST | Includes vector models and general large models | Supports specifying different models and knowledge bases via API interfaces, meeting flexible invocation requirements for financial scenarios |
INCREMENTAL_SYNC_INTERVAL | 300 seconds | Balances real-time update needs for bidding announcements and server load |
METADATA_INDEX_FIELDS | Project ID, budget amount, construction period | Matches core filtering dimensions for infrastructure engineering retrieval, supporting precise targeting of target projects |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Adapts to parsing times for large infrastructure research reports, avoiding mid-process parsing interruptions |
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. Specific issues require specific analysis, and testing on local samples is recommended before finalizing settings.
Three Common Configuration Errors
- Issue: When calling a publishing channel via the API interface, custom models or knowledge bases cannot be specified. Cause: The permission scope of the corresponding models and knowledge bases is not configured in
API_ENABLE_MODEL_LIST, resulting in restricted interface calls. - Issue: The publishing channel returns outdated workflow logic with no update prompts. Cause: Automatic sync rules for publishing channels and workflows are not configured. Only the local workflow is modified without syncing to the publishing channel node.
- Issue: The similarity value returned by the vector model exceeds 10000, and the built-in 0-1 range filtering rule cannot be applied. Cause: Raw similarity results from the vector model are not normalized to the 0-1 range, and raw output values are directly used as filtering criteria.
How to Verify Successful Configuration
- Upload a test infrastructure engineering research report, review the parsed segmentation results, and confirm that core fields are not truncated.
- Submit a retrieval request for infrastructure projects, check the similarity values of returned results, and adjust the threshold to meet business filtering requirements.
- Modify the associated workflow logic, call the publishing channel interface, and confirm that returned results match the latest workflow configuration.
- Review access permission configurations for the publishing channel, adjust settings to allow access for all users, and retain configuration permissions only for internal administrators.
- View index logs to confirm that incremental sync tasks execute at the set interval, with no duplicate or missing document indexing records.
