What the data for this category looks like
Railway and highway related financial report data primarily comes from periodic reports of domestic and overseas listed transportation enterprises, and public operation statistics released by industry regulatory authorities. Disclosure timelines follow regulatory requirements: quarterly reports are released within 30 days after the end of the quarter, annual reports are released within 4 months after the end of the year, and monthly operation data is published by the 15th of the following month.
Document structures include consolidated financial statements and detailed operation schedules. Fields cover passenger volume, freight turnover, toll revenue, maintenance mileage, and similar metrics. Most units use standardized formats such as ten thousand person-trips, hundred million ton-kilometers, ten thousand yuan, and kilometers.
What constraints these characteristics impose on model access and configuration
The multi-time granularity, lengthy detailed documents, and specialized field traits of railway and highway financial reports create multiple constraints for model access and configuration. Multi-cycle operation data requires configuration of time tag-based data source filtering to prevent mixing of monthly, quarterly, and annual data. Long-form operation schedules need adjusted paragraph parsing parameters to adapt to single-file length limits. Specialized measurement fields such as freight turnover and toll revenue have dedicated measurement units. Model prompts must bind corresponding rules to avoid mismatches between numerical values and units. Data surges during concentrated disclosure periods require configuration of API call concurrency limits to avoid rate-limiting risks. Some public operation data comes from industry web pages, so non-local file access rules must be adapted.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 900 seconds | Railway and highway financial report operation schedules have lengthy content; standard parsing durations are insufficient for complete splitting |
CHUNK_MAX_SIZE | 8000–12000 characters | Adapt to long-length detailed operation schedules and avoid truncating combinations of specialized fields during segmentation |
RECALL_TOP_N | Top 8 entries | Railway and highway financial reports have multiple dimensions of operation fields; sufficient segmented recall is needed to cover core data |
SIMILARITY_THRESHOLD | 0.75–0.85 | Distinguish similar operation indicator fields in financial reports and avoid recalling irrelevant financial data paragraphs |
UPLOAD_FILE_MAX_SIZE | 500 MB | Some annual financial reports include multi-page detailed operation attachments; larger file upload support is required |
MODEL_SELECTOR | gpt-4o-mini / claude-3-haiku | Adapt to text understanding requirements for financial report analysis and balance cost and accuracy |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require case-by-case analysis. Testing on relevant samples is recommended before finalizing configuration settings.
Three common configuration errors
- Phenomenon: Workflow calls return a
401 Unauthorizederror, or display the prompt "Invalid API Key". Cause: Global universal API keys and application-specific API keys are mixed, and the bound key of the target workflow is not used. - Phenomenon: After uploading financial report images converted by an external Python script, the workflow cannot read the file content, and the file list is empty. Cause: Unified file storage path rules are not configured, so the workflow cannot locate the uploaded target files.
- Phenomenon: No response is returned after initiating a workflow call, or the prompt "Workflow does not exist" is displayed. Cause: The call is not initiated using the unique identifier ID of the workflow, or the ID parameter is misspelled.
How to confirm successful configuration
- Upload a standard railway and highway financial report file, verify that the parsed segments completely cover the detailed operation content, and check that the segments conform to the configured segment length rules.
- Initiate a single workflow call, review the returned status code, and confirm that no permission or rate-limiting related errors appear.
- Configure a test prompt to initiate queries targeting financial report fields, verify that the recalled text paragraphs match the target operation indicators, and adjust relevant parameters to optimize recall effects.
- Batch upload multiple financial report datasets of different cycles, check that the workflow can correctly distinguish data sources of different time granularities.
