What This Category’s Data Looks Like
Railway and highway financing daily report data is sourced from the official website of the Ministry of Transport, public announcement platforms of provincial transportation departments, and project filing channels of the National Development and Reform Commission. Data is updated daily to aggregate newly disclosed financing projects released on that day. Each structured record includes fields such as project name, affiliated section/route, financing amount, financing subject, capital source channel, disclosure date, and approval document number. Amounts are marked in ten thousand yuan or hundred million yuan. Some data includes the original link to the official approval document.
Constraints on Citation Sources and Traceability Workflow
Since data sources are scattered across national and provincial official platforms, configure multi-source recall priority rules to ensure the most authoritative official disclosure information is retrieved first. Each record includes unique identifier fields such as approval document number and disclosure date. Use these fields as core traceability association bases to avoid matching deviations during recall. Financing amounts use two units: ten thousand yuan and hundred million yuan. Complete unit standardization verification before traceability to ensure numerical consistency in cited content. The data has a daily incremental update feature. Configure incremental synchronization rules to avoid repeatedly recalling already processed historical projects.
Configuration Settings
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
recall_top_k | 6-8 results | Railway and highway financing daily reports have large per-record information volume. Too many recalled results will cause redundant context. Too few will fail to cover complete financing details |
similarity_threshold | 0.75-0.85 | Most fields in financing daily reports are structured content. A high similarity threshold is required to avoid recalling irrelevant transportation project data |
source_link_enable | Enabled | Most railway and highway financing projects include official approval links. Retaining these links allows direct traceability verification |
incremental_sync_interval | Every 24 hours | Data is updated daily to disclose new projects. Incremental synchronization prevents repeated processing of historical data |
id_field_name | Approval document number | The approval document number is the unique identifier for each financing project, and can be used as the traceability ID for cited data |
parse_pdf_keep_origin_page | Enabled | Some financing daily reports are released in PDF format. Retaining original page numbers allows precise location of the source position of cited content |
The parameter values provided on this page are conventional recommendations used to set starting points for configurations. Actual values are affected by material format, data volume, and business rules. Specific issues require individual analysis. It is recommended to test on your own samples before finalizing settings.
Three Common Misconfigurations
- Scenario: After batch uploading 100 5KB financing daily report files, half of the training tasks fail. The cause is that no reasonable value is configured for the
file_parse_timeoutparameter, leading to timeout interruptions during batch parsing of small files. - Scenario: Original official disclosure pages cannot be linked when citing content. The cause is that the
source_link_enableparameter is not enabled, and official source link information for the data is not retained. - Scenario: Duplicate citations of historical financing projects appear after incremental synchronization. The cause is that
id_field_nameis not configured with a unique identifier field such as the approval document number. Instead, a generic file collection ID is used as the traceability identifier, making it impossible to accurately distinguish between different projects.
How to Verify Proper Configuration
- Randomly select 3 uploaded financing daily report data entries, check that the amount units in the cited content are unified, and confirm that the field mapping rules are effective.
- View the recall results in the knowledge base, confirm that each cited content includes an official source link, and verify that the
source_link_enableparameter is configured correctly. - Run an incremental synchronization task, check that only newly added financing projects on that day are recalled, and no historical data is processed repeatedly, confirming that the incremental synchronization interval configuration is reasonable.
- View the traceability ID of the cited content, confirm that it displays the approval document number, and verify that the
id_field_nameparameter is configured correctly.
