Data Characteristics for This Category
Infrastructure construction financial report data is primarily sourced from project ledgers, bidding documents, monthly progress reports, and quarterly and annual settlement reports. Update frequency is adjusted based on project cycles and official disclosure requirements. A single project financial report document typically includes five modules: project overview, bill of quantities, cost accounting, progress payment, and safety and quality inspection. Fields include section numbers, project IDs, engineering quantities (units such as cubic meters, square meters, tons, etc.), unit costs (unit: yuan per unit engineering quantity), construction periods (unit: days), and other professional content. Some data exists in unstructured text format, with no unified, fixed general report template.
Constraints on Model Access and Configuration
The multi-source, dispersed nature of infrastructure construction financial reports requires configuring multi-source data access adaptation rules to accommodate format differences between structured ledgers and unstructured reports. Frequently updated project data requires configuring trigger parameters for scheduled synchronization tasks, to ensure the model’s data source always matches the latest project progress. The combination of long documents and specialized fields requires adjusting context window and segmentation parameters, to avoid breaking the associated integrity of professional fields. Differences in fields across projects require configuring custom mapping rules for entity extraction, to adapt to the financial report formats of different projects.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
maxContext | 8000-12000 characters | Single infrastructure construction financial report documents have high word counts, and need to accommodate complete project ledgers and progress data to avoid context truncation |
PARSE_FILE_TIMEOUT_SECONDS | 900 seconds | Parsing large infrastructure financial report documents takes significant time, and default parameters cannot cover the full parsing cycle |
UPLOAD_FILE_MAX_SIZE | 2000 MB | Single bidding and settlement report files are typically large, requiring support for large file uploads |
chunkSize | 1500-2000 characters | Infrastructure financial reports include specialized engineering quantity fields. Excessively long segments will damage the associated integrity of these fields |
similarity_threshold | 0.75 | Professional fields such as project ID and engineering quantity unit must be accurately identified to reduce the probability of incorrect extraction |
recall_top_k | Top 8 entries | Professional fields in infrastructure financial reports have strong relevance, requiring recall of sufficient associated paragraphs to support analysis |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis, and it is recommended to test on your own samples before finalizing the configuration.
Three Common Configuration Mistakes
- Phenomenon: The model call returns the
413 Request Entity Too Largeerror. Cause: TheUPLOAD_FILE_MAX_SIZEparameter is not adjusted, and large infrastructure financial report files cannot be uploaded because they exceed the default limit. - Phenomenon: Missing or incorrect units appear in parsed financial report fields. Cause: The
similarity_thresholdparameter is not configured, or the value is set too high, resulting in failure to correctly extract professional engineering quantity units. - Phenomenon: A
model not founderror occurs after accessing a third-party self-developed model. Cause: The unique model identifier provided by the manufacturer is not correctly filled in the model configuration, causing the platform to fail to match the corresponding model.
How to Verify Successful Configuration
- Upload a single large infrastructure financial report document, confirm the upload progress completes without
413-class errors. - Trigger a model parsing task, and check that parsed fields include preset professional fields such as project ID and engineering quantity unit.
- Initiate a financial report analysis request, confirm the response completes within the preset timeout period with no interruption prompts.
- Adjust the segments of the test financial report document, confirm that the engineering quantity analysis output by the model has no logical breaks.
